エレベータ制御装置は、エレベータに供給する電力を出力する電力変換回路部や、商用交流電源などの建屋電源からの電力を受電する受電回路部などが筐体に格納される、制御盤によって構成される。高速および超高速エレベータ用のエレベータ制御装置は、制御盤の寸法が大きくなり、また複数の制御盤からなるため、通常、機械室に配置され、機械室内において、建屋電源や巻上機と電力線(電力ケーブル)によって電気的に接続される。   The elevator control device is configured by a control panel in which a power conversion circuit unit that outputs power to be supplied to the elevator, a power reception circuit unit that receives power from a building power source such as a commercial AC power source, and the like are stored in a housing. . Elevator control devices for high-speed and ultra-high-speed elevators have a large control panel and are composed of a plurality of control panels. Therefore, they are usually placed in the machine room, and the building power supply and hoisting machine are connected to the power line ( Electrically connected by a power cable).

上記従来技術では、制御盤の下方のスペースが少なく、線径が大きく曲げにくい電力線の敷設作業の作業性が低いという問題がある。特に、電力変換回路部に適用される半導体デバイスおよびパワーエレクトロニクス技術の進歩により、電力変換回路部の小型・高密度化が進み、配線スペースがさらに少なくなっている。このため、作業性がより一層低下することが懸念される。   The above-described prior art has a problem that there is little space below the control panel, and the workability of laying a power line that has a large wire diameter and is difficult to bend is low. In particular, advances in semiconductor devices and power electronics technology applied to the power conversion circuit unit have led to a reduction in size and increase in the density of the power conversion circuit unit, further reducing wiring space. For this reason, we are anxious about workability falling further.

さらに、電力線が交差する箇所では、ダクトを深くしたり、床面上に突出させたりしなければならず、作業者の機械室内での作業の妨げになるなど、電力線敷設の作業性や保守作業性の低下を招く。また、電力線が交差しないようにすると、ダクトの幅が広がり、狭い機械室においてダクトが占めるスペースが増えてしまう。   In addition, at locations where power lines intersect, the ducts must be deepened or protruded above the floor, which hinders the operator's work in the machine room. It causes a decline in sex. Further, if the power lines are not crossed, the width of the duct increases, and the space occupied by the duct increases in a narrow machine room.

Filter panel 3 provided with a power supply unit, main circuit boards 41 and 42 provided with power conversion circuit units for converting power from a building power source into AC power of variable voltage and variable frequency, and power control circuit units, and elevator control devices 1 is composed of a signal board 5 having a control circuit unit that communicates with the outside.

図3は、実施例1のエレベータ制御装置の概略回路構成を示す。なお、特に断らない限り、以下の構成において、制御盤間、部品間および回路部間は電力線によって接続される。   FIG. 3 shows a schematic circuit configuration of the elevator control apparatus according to the first embodiment. Unless otherwise specified, in the following configuration, control panels, components, and circuit units are connected by power lines.

商用の三相交流電源が適用される建屋電源81から受電盤2の端子台71に電力線が接続される。受電盤2においては、主遮断器20が端子台71に接続され、主遮断器20から、並列に2系統に分かれて、一方の系統は電磁接触器21を介して端子台72に接続され、他方の系統は電磁接触器22を介して端子台73に接続される。   A power line is connected to the terminal block 71 of the power receiving panel 2 from a building power supply 81 to which a commercial three-phase AC power supply is applied. In the power receiving panel 2, the main circuit breaker 20 is connected to the terminal block 71, divided into two systems in parallel from the main circuit breaker 20, and one system is connected to the terminal block 72 via the electromagnetic contactor 21, The other system is connected to the terminal block 73 via the electromagnetic contactor 22.

フィルタ盤3において、フィルタ回路部31の一端(入力端子)および他端(出力端子)は、それぞれ、受電盤2の端子台72および主回路盤41の端子台74に接続され、フィルタ回路部32の一端(入力端子)および他端(出力端子)は、それぞれ、受電盤2の端子台73および主回路盤42の端子台76に接続される。なお、本実施例1では、フィルタ盤3には端子台を設けずに、フィルタ回路部31,32を構成するリアクトル等の端子に電力線を直接接続する。   In the filter panel 3, one end (input terminal) and the other end (output terminal) of the filter circuit unit 31 are connected to the terminal block 72 of the power receiving panel 2 and the terminal block 74 of the main circuit board 41, respectively. One end (input terminal) and the other end (output terminal) are connected to the terminal block 73 of the power receiving panel 2 and the terminal block 76 of the main circuit board 42, respectively. In the first embodiment, the filter panel 3 is not provided with a terminal block, and a power line is directly connected to terminals such as reactors constituting the filter circuit units 31 and 32.

主回路盤41においては、電力変換回路部10の入力が端子台74に接続され、電力変換回路部10の出力がリアクトル40を介して端子台75に接続される。また、主回路盤42においても、電力変換回路部10の入力が端子台76に接続され、電力変換回路部10の出力がリアクトル40を介して端子台77に接続される。各電力変換回路10は、信号盤5が備える制御回路部50から信号線によって伝送される制御信号によって制御され、所望の電動機速度に応じて、可変電圧可変周波数の三相交流電力を出力する。なお、制御回路部50は、通信用の信号線を介して、外部機器との通信も行う。   In the main circuit board 41, the input of the power conversion circuit unit 10 is connected to the terminal block 74, and the output of the power conversion circuit unit 10 is connected to the terminal block 75 via the reactor 40. Also in the main circuit board 42, the input of the power conversion circuit unit 10 is connected to the terminal block 76, and the output of the power conversion circuit unit 10 is connected to the terminal block 77 via the reactor 40. Each power conversion circuit 10 is controlled by a control signal transmitted from a control circuit unit 50 included in the signal board 5 through a signal line, and outputs three-phase AC power with variable voltage and variable frequency according to a desired motor speed. Note that the control circuit unit 50 also communicates with an external device via a communication signal line.

主回路盤41,42から出力される三相交流電力は、端子台75,77に接続される電力線によって巻上機用の電動機82に供給される。供給された三相交流電力によって電動機82が回転すると、巻上機に巻き掛けられる主ロープ84が駆動される。これにより、図示されない昇降路内において、主ロープ84によって吊られる乗りかご83および釣り合い錘85が、昇降路内を昇降する。   The three-phase AC power output from the main circuit boards 41 and 42 is supplied to the motor 82 for the hoisting machine through a power line connected to the terminal blocks 75 and 77. When the electric motor 82 is rotated by the supplied three-phase AC power, the main rope 84 wound around the hoisting machine is driven. Thereby, in the hoistway (not shown), the car 83 and the counterweight 85 suspended by the main rope 84 move up and down in the hoistway.

図4は、図3における電力変換回路部10の回路構成を示す。図4に示すように、電力変換回路部10は、建屋電源81(図3)からの商用三相交流電力を直流電力に変換するコンバータ101と、コンバータ101の出力電圧を平滑化する平滑コンデンサ103と、平滑コンデンサ103を介してコンバータ101から入力する直流電力を三相交流電力に変換するインバータ102とから構成される。コンバータ101およびインバータ102は、半導体スイッチング素子(図4ではIGBT)およびダイオードが逆並列に接続される上下アームが直列に接続されるアーム回路を内蔵するパワーモジュール100を交流の相数分すなわち3個もちいて3相ブリッジ回路が構成される。図3に示した信号盤5が備える制御回路部50から信号線によって伝送される制御信号によって、半導体スイッチング素子がオン・オフ制御されることにより、コンバータ101は上述したように商用三相交流電力を直流電力に変換するとともに、電動機82が回生運転される場合に回生電力を建屋電源81に回生する。また、半導体スイッチング素子がオン・オフ制御されることにより、インバータ102は、入力した直流電力を、所望の電動機速度に応じて、可変電圧可変周波数の三相交流電力に変換して出力する。   FIG. 4 shows a circuit configuration of the power conversion circuit unit 10 in FIG. As shown in FIG. 4, the power conversion circuit unit 10 includes a converter 101 that converts commercial three-phase AC power from a building power supply 81 (FIG. 3) into DC power, and a smoothing capacitor 103 that smoothes the output voltage of the converter 101. And an inverter 102 that converts DC power input from the converter 101 through the smoothing capacitor 103 into three-phase AC power. The converter 101 and the inverter 102 include three power modules 100 each having the number of AC phases, that is, three power modules 100 each including a semiconductor switching element (IGBT in FIG. 4) and an arm circuit in which upper and lower arms to which diodes are connected in antiparallel are connected in series. Using this, a three-phase bridge circuit is constructed. The semiconductor switching element is controlled to be turned on / off by a control signal transmitted through a signal line from the control circuit unit 50 included in the signal board 5 shown in FIG. Is converted to DC power, and the regenerative power is regenerated to the building power supply 81 when the motor 82 is regeneratively operated. In addition, by turning on / off the semiconductor switching element, the inverter 102 converts the input DC power into three-phase AC power having a variable voltage and variable frequency according to a desired motor speed, and outputs the three-phase AC power.

次に、本実施例1のエレベータ制御装置における電力線の敷設について、図2(a)〜(c)を参照しながら説明する。なお、図2(a)は、エレベータ制御装置の前面側を示し、かつ、配線状態を分かりやすくするため扉あるいは蓋が除かれた状態を示す。図2(b)は、エレベータ制御装置の前面側の反対側、すなわち背面側を示し、かつ、同様に扉あるいは蓋が除かれた状態を示す。図2(c)は、図2(a)における断面A−A’の矢視図である。   Next, the laying of power lines in the elevator control apparatus according to the first embodiment will be described with reference to FIGS.

さらに、図2(a)が示すように、主回路盤41内において、電力変換回路部10は、その上端が主回路盤41の上端側に隣接するように設置され、リアクトル40および端子台74は電力回路部10の下方において、主回路盤41の下端側に隣接するように設置される。また、主回路盤41の前面側において、リアクトル40および端子台74は、この順で右左に横一列に並設される。すなわち、フィルタ盤3と端子台74との間には、主回路盤41のリアクトル40が位置する。また、主回路盤42内において、電力変換回路部10は、その上端が主回路盤42の上端側に隣接するように設置され、リアクトル40および端子台76は電力回路部10の下方において、主回路盤42の下端側に隣接するように設置される。また、主回路盤42の前面側において、リアクトル40および端子台76は、この順で右左に横一列に並設される。すなわち、フィルタ盤3と端子台76との間には、少なくとも主回路盤41のリアクトル40が位置する。なお、本実施例1においては、フィルタ盤3と端子台76との間に、主回路盤41および信号盤5も介在している。   Further, as shown in FIG. 2A, the power conversion circuit unit 10 is installed in the main circuit board 41 so that the upper end thereof is adjacent to the upper end side of the main circuit board 41, and the reactor 40 and the terminal block 74. Is installed below the power circuit unit 10 so as to be adjacent to the lower end side of the main circuit board 41. In addition, on the front side of the main circuit board 41, the reactor 40 and the terminal block 74 are arranged side by side in a horizontal row on the right and left in this order. That is, the reactor 40 of the main circuit board 41 is located between the filter board 3 and the terminal block 74.

In the first embodiment, the main circuit board 41 and the signal board 5 are also interposed between the filter board 3 and the terminal block 76.

なお、端子台72,73,74,76およびフィルタ回路部31,32の一端および他端は、各々、交流3相分の端子すなわち3個の端子を備える。そして、この3個の端子は、各制御盤の幅方向に横一列に並ぶように配置される。   Note that one end and the other end of the terminal blocks 72, 73, 74, and 76 and the filter circuit units 31 and 32 are each provided with terminals for three phases of AC, that is, three terminals. The three terminals are arranged in a horizontal row in the width direction of each control panel.

上記のようなエレベータ制御装置の前面側において、端子台72とフィルタ回路部31の一端は、端子台72とフィルタ回路部31の一端との間に敷設される電力線によって、電気的に接続される。同様に、端子台73とフィルタ回路部32の一端も、電力線によって電気的に接続される。また、同前面側において、フィルタ回路部31の他端と端子台74は、フィルタ回路部31の他端と端子台74との間に敷設される電力線によって、電気的に接続される。同様に、フィルタ回路部32の他端と端子台76も、電力線によって電気的に接続される。   On the front side of the elevator control apparatus as described above, one end of the terminal block 72 and the filter circuit unit 31 is electrically connected by a power line laid between the terminal block 72 and one end of the filter circuit unit 31. . Similarly, the terminal block 73 and one end of the filter circuit unit 32 are also electrically connected by a power line. Further, on the front side, the other end of the filter circuit unit 31 and the terminal block 74 are electrically connected by a power line laid between the other end of the filter circuit unit 31 and the terminal block 74. Similarly, the other end of the filter circuit unit 32 and the terminal block 76 are also electrically connected by a power line.

端子台72に接続される電力線は、受電盤2内を下方へ伸び、配線箱62内で曲げられ、配線箱62内を通って、さらに配線箱63内を通ると共に配線箱63内で曲げられ、受電盤2側のフィルタ盤3の筐体側面に沿ってフィルタ盤3内を上方へ伸びて、フィルタ回路部31の一端に接続される。端子台73に接続される電力線は、受電盤2内を下方へ伸び、配線箱62内で曲げられ、配線箱62内を通って、さらに配線箱63内を通ると共に配線箱63内で曲げられ、受電盤2側のフィルタ盤3の筐体側面に沿ってフィルタ盤3内を上方へ伸びて、フィルタ回路部32の一端に接続される。   The power line connected to the terminal block 72 extends downward in the power receiving panel 2, is bent in the wiring box 62, passes through the wiring box 62, further passes through the wiring box 63 and is bent in the wiring box 63. The filter board 3 extends upward along the side surface of the housing of the filter board 3 on the power receiving board 2 side and is connected to one end of the filter circuit unit 31. The power line connected to the terminal block 73 extends downward in the power receiving panel 2, is bent in the wiring box 62, passes through the wiring box 62, further passes through the wiring box 63 and is bent in the wiring box 63. The filter board 3 extends upward along the side surface of the housing of the filter board 3 on the power receiving board 2 side, and is connected to one end of the filter circuit unit 32.

フィルタ回路部31の他端に接続される電力線は、受電盤2側の反対側(主回路盤41側)のフィルタ盤3の筐体側面に沿ってフィルタ盤3内を下方へ伸び、配線箱63内を通ると共に配線箱63内で曲げられ、さらに配線箱64内を通ると共に配線箱64内で曲げられ、主回路盤41内を上方へ伸びて、端子台74に接続される。フィルタ回路部32の他端に接続される電力線は、フィルタ盤3内を下方へ伸び、配線箱63内を通ると共に配線箱63内で曲げられ、さらに配線箱64内、配線箱65内および配線箱66内を順次通って、さらに配線箱66内で曲げられ、主回路盤42内を上方へ伸びて、端子台76に接続される。   The power line connected to the other end of the filter circuit unit 31 extends downward in the filter board 3 along the side of the housing of the filter board 3 on the side opposite to the power receiving board 2 side (main circuit board 41 side). It passes through 63 and is bent in the wiring box 63, further passes through the wiring box 64 and is bent in the wiring box 64, extends upward in the main circuit board 41, and is connected to the terminal block 74. The power line connected to the other end of the filter circuit section 32 extends downward in the filter panel 3, passes through the wiring box 63 and is bent in the wiring box 63, and further in the wiring box 64, the wiring box 65, and the wiring. The box 66 is sequentially passed through the box 66, further bent in the wiring box 66, extends upward in the main circuit board 42, and is connected to the terminal block 76.

なお、本実施例においては、電力線として、絶縁被覆も含めて直径20〜40mmの電力ケーブルが適用される。従って、本実施例の電力線は、一般的には、大きな曲率では曲げにくい。   In this embodiment, a power cable having a diameter of 20 to 40 mm including the insulation coating is applied as the power line. Therefore, the power line of the present embodiment is generally difficult to bend with a large curvature.

上述したように、端子台72,73,74,76およびフィルタ回路部31,32の端子がエレベータ制御装置1の前面側に配置されているので、制御盤間を接続する電力線はエレベータ制御装置1の前面側において接続され、図2(c)に示すように、各配線箱内において、エレベータ制御装置1の前面側寄りに敷設される。これにより、電力線を、配線箱内において背面側と前面側との間に敷設するような作業が低減されたり不要になったりするとともに、各配線箱内にスペースが確保され、電力線の敷設作業が容易になる。   As described above, since the terminals of the terminal blocks 72, 73, 74, 76 and the filter circuit units 31, 32 are arranged on the front side of the elevator control device 1, the power line connecting the control panels is the elevator control device 1. As shown in FIG. 2 (c), it is laid near the front side of the elevator control device 1 in each wiring box. As a result, the work of laying the power line between the back side and the front side in the wiring box is reduced or unnecessary, space is secured in each wiring box, and the laying work of the power line is performed. It becomes easy.

また、主回路盤41において、端子台74とフィルタ盤3との間には、リアクトル40が介在する。すなわち、端子台74は、主回路盤41において、主回路盤41の筐体側面の内、フィルタ盤3とは反対側の筐体側面により近く位置する。このため、端子台74はフィルタ盤3から横方向に離れているので、フィルタ回路部31の他端に接続される電力線は、配線箱64内において比較的大きな曲率半径で曲げて端子台74に接続することができる。また、端子台76は、主回路盤42において、主回路盤42の筐体側面の内、フィルタ盤3とは反対側の筐体側面により近く位置する。さらに、主回路盤42とフィルタ盤3との間には、主回路盤41および信号盤5が介在する。このため、端子台76はフィルタ盤3から横方向に離れているので、フィルタ回路部32の他端に接続される電力線は、配線箱66内において比較的大きな曲率半径で曲げて端子台76に接続することができる。従って、配線箱内での電力線の制御盤間敷設作業が容易になり、敷設作業の作業性が向上する。   In the main circuit board 41, the reactor 40 is interposed between the terminal block 74 and the filter board 3. That is, in the main circuit board 41, the terminal block 74 is located closer to the side of the casing opposite to the filter board 3 in the casing side of the main circuit board 41. For this reason, since the terminal block 74 is laterally separated from the filter panel 3, the power line connected to the other end of the filter circuit section 31 is bent with a relatively large radius of curvature in the wiring box 64 to the terminal block 74. Can be connected. Further, the terminal block 76 is located closer to the side of the casing on the opposite side of the filter board 3 from the side of the casing of the main circuit board 42 in the main circuit board 42. Further, the main circuit board 41 and the signal board 5 are interposed between the main circuit board 42 and the filter board 3. For this reason, since the terminal block 76 is laterally separated from the filter panel 3, the power line connected to the other end of the filter circuit section 32 is bent with a relatively large radius of curvature in the wiring box 66 to the terminal block 76. Can be connected. Therefore, the work for laying the power lines between the control panels in the wiring box is facilitated, and the workability of the laying work is improved.

次に、図2(b)に示すように、受電用の端子台71は、受電盤2の背面側において、受電盤2の高さ方向の中央付近に位置する。また、端子台75は、主回路盤41の背面側の下端部内において、主回路盤41の筐体側面の内、フィルタ盤3側の筐体側面により近く位置し、かつリアクトル40に対向する。さらに、端子台77は、主回路盤42の背面側の下端部内において、主回路盤42の筐体側面の内、フィルタ盤3側の筐体側面により近く位置し、かつリアクトル40に対向する。   Next, as shown in FIG. 2B, the power receiving terminal block 71 is located near the center of the power receiving board 2 in the height direction on the back side of the power receiving board 2. Further, the terminal block 75 is located closer to the housing side surface of the main circuit board 41 on the filter board 3 side in the lower end portion on the back side of the main circuit board 41, and faces the reactor 40. Further, the terminal block 77 is located closer to the housing side surface of the main circuit board 42 on the filter board 3 side in the lower end portion on the back side of the main circuit board 42, and faces the reactor 40.

なお、端子台71,75,77は、各々、交流3相分の端子すなわち3個の端子を備える。そして、この3個の端子は、各制御盤の幅方向に横一列に並ぶように配置される。   Each of the terminal blocks 71, 75, 77 includes terminals for three AC phases, that is, three terminals. The three terminals are arranged in a horizontal row in the width direction of each control panel.

図2(b)に示すように、建屋電源81からの電力線は、配線箱62の側面から配線箱62内へ引き込まれ、配線箱62内で曲げられて、受電盤2内において受電盤2の高さ方向に伸び、端子台71に接続される。本実施例1のエレベータ制御装置1は2台の主回路盤41,42を備えるため、建屋電源81から取り込む電力が大きくなるので、端子台71には、一相当たり2本(三相で計6本)の電力線が接続される。端子台75に接続される電力線は、主回路盤41内で下方へ伸び、配線箱64内で曲げられ、配線箱64,65,66を通って、配線箱66の側面から外部へ取り出される。また、端子台77に接続される電力線は、主回路盤42内で下方へ伸び、配線箱66内で曲げられ、配線箱66を通って、配線箱66の側面から外部へ取り出される。配線箱66から取り出された各電力線は、エレベータ制御装置1と共に機械室内に設置される巻上機の電動機に接続される。   As shown in FIG. 2 (b), the power line from the building power supply 81 is drawn into the wiring box 62 from the side surface of the wiring box 62, is bent in the wiring box 62, and is connected to the power receiving board 2 in the power receiving board 2. It extends in the height direction and is connected to the terminal block 71. Since the elevator control apparatus 1 according to the first embodiment includes the two main circuit boards 41 and 42, the power to be taken in from the building power supply 81 is increased. Therefore, two terminals per phase (total of three phases are included in the terminal block 71). 6 power lines are connected. The power line connected to the terminal block 75 extends downward in the main circuit board 41, is bent in the wiring box 64, passes through the wiring boxes 64, 65 and 66, and is taken out from the side surface of the wiring box 66. The power line connected to the terminal block 77 extends downward in the main circuit board 42, is bent in the wiring box 66, passes through the wiring box 66, and is taken out from the side surface of the wiring box 66. Each power line taken out from the wiring box 66 is connected to an electric motor of a hoisting machine installed in the machine room together with the elevator control device 1.

上述したように、端子台71,75,77がエレベータ制御装置1の背面側に配置されているので、建屋電源および巻上機用の電動機、すなわち外部と、制御盤との間を接続する電力線は、エレベータ制御装置1の背面側において接続され、図2(c)に示すように、各配線箱内において、エレベータ制御装置1の背面側寄りに敷設される。これにより、電力線を、配線箱内において背面側と前面側との間に敷設するような作業が低減されたり不要になったりするとともに、各配線箱内にスペースが確保され、電力線の敷設作業が容易になる。   As described above, since the terminal blocks 71, 75, 77 are arranged on the back side of the elevator control device 1, the building power supply and the hoisting motor, that is, the power line connecting the outside and the control panel Are connected on the back side of the elevator control device 1 and are laid near the back side of the elevator control device 1 in each wiring box as shown in FIG. As a result, the work of laying the power line between the back side and the front side in the wiring box is reduced or unnecessary, space is secured in each wiring box, and the laying work of the power line is performed. It becomes easy.

また、端子台71は、受電盤2の高さ方向の中央付近に位置するため、配線箱62の側面から引き込まれる電力線は、配線箱62内において比較的大きな曲率半径で曲げて端子台71に接続することができる。さらに、端子台75は、主回路盤41内においてフィルタ盤3側の筐体側面に隣接する。すなわち、端子台75は、主回路盤41の筐体側面の内、電力線が巻上機へ向かって引き出される配線箱66の側面側とは反対側における筐体側面により近く位置する。このため、端子台75に接続される電力線は、配線箱64内で曲げられた後、配線箱64内を水平方向へ伸びるように敷設される。これにより、電力線は、比較的大きな曲率半径で曲げて端子台75に接続することができる。また、端子台77は、主回路盤42内においてフィルタ盤3側の筐体側面に隣接する。すなわち、端子台77は、主回路盤42の筐体側面の内、電力線が巻上機へ向かって引き出される配線箱66の側面側とは反対側における筐体側面により近く位置する。このため、端子台77に接続される電力線は、配線箱66内で曲げられた後、配線箱66内を水平方向へ伸びるように敷設される。これにより、電力線は、比較的大きな曲率半径で曲げて端子台77に接続することができる。従って、配線箱内での電力線の制御盤と外部間における敷設作業が容易になり、敷設作業の作業性が向上する。   Further, since the terminal block 71 is located near the center in the height direction of the power receiving panel 2, the power line drawn from the side surface of the wiring box 62 is bent at a relatively large radius of curvature in the wiring box 62 to the terminal block 71. Can be connected. Further, the terminal block 75 is adjacent to the side surface of the housing on the filter board 3 side in the main circuit board 41. That is, the terminal block 75 is located closer to the side of the casing on the side opposite to the side of the wiring box 66 from which the power line is drawn out toward the hoisting machine among the side of the casing of the main circuit board 41. For this reason, the power line connected to the terminal block 75 is laid so as to extend in the horizontal direction in the wiring box 64 after being bent in the wiring box 64. As a result, the power line can be bent and connected to the terminal block 75 with a relatively large radius of curvature. The terminal block 77 is adjacent to the side surface of the housing on the filter board 3 side in the main circuit board 42. That is, the terminal block 77 is located closer to the side of the casing on the side opposite to the side of the wiring box 66 from which the power line is drawn out toward the hoisting machine among the side of the casing of the main circuit board 42. Therefore, the power line connected to the terminal block 77 is laid so as to extend in the horizontal direction in the wiring box 66 after being bent in the wiring box 66. Thereby, the power line can be bent with a relatively large radius of curvature and connected to the terminal block 77. Therefore, the installation work between the control panel of the power line in the wiring box and the outside becomes easy, and the workability of the installation work is improved.

図2(c)に示すように、受電盤2とフィルタ盤3との間の電力線、フィルタ盤3と主回路盤41,42との間の電力線はエレベータ制御装置1の前面寄りの位置に敷設され、建屋電源と受電盤2との間の電力線、主回路盤41,42と電動機との間の電力線はエレベータ制御装置1の背面寄りに敷設される。このため、配線箱内における電力線の交差を低減あるいはなくすことができるので、作業性が向上すると共に、配線箱の高さを低減することができる。   As shown in FIG. 2 (c), the power line between the power receiving panel 2 and the filter panel 3 and the power line between the filter panel 3 and the main circuit board 41, 42 are laid at a position near the front surface of the elevator control device 1. The power line between the building power supply and the power receiving panel 2 and the power line between the main circuit boards 41 and 42 and the motor are laid near the back of the elevator control device 1. For this reason, since the intersection of the power lines in the wiring box can be reduced or eliminated, the workability is improved and the height of the wiring box can be reduced.

なお、図2(a)〜(c)には図示されないが、信号盤5が備える制御回路部には、配線箱66の側面から引き込まれ、配線箱66,65を通る通信用信号線が接続される。なお、通信用信号線および前述した電力変換回路部を制御するための信号線は、扱う電力が小さいため、電力線に比べ直径が小さくかつ曲げ易い。この通信用信号線は、乗りかご83(図3)が備える機器や図示していない各階乗場に備えられる機器に接続され、これらの機器と信号盤5との間における通信に用いられる。図2(c)に示すように、電力線がエレベータ制御装置1の前面側寄りおよび背面側寄りに敷設されることにより、配線箱65,66図2(c)において破線で記すような通信用信号線を敷設するためのスペースAを広く確保できる。これにより、配線箱内における通信用信号線の敷設作業が容易化され、作業性が向上する。   Although not shown in FIGS. 2A to 2C, communication signal lines that are drawn from the side surface of the wiring box 66 and pass through the wiring boxes 66 and 65 are connected to the control circuit unit included in the signal board 5. Is done. Note that the communication signal line and the signal line for controlling the power conversion circuit unit described above have a small power and are easy to bend compared to the power line because the power handled is small. This communication signal line is connected to equipment provided in the car 83 (FIG. 3) and equipment provided in each floor hall (not shown), and is used for communication between these equipment and the signal board 5. As shown in FIG. 2 (c), the power line is laid near the front side and the back side of the elevator control device 1, so that the communication signal as indicated by the broken line in FIG. A wide space A for laying the wire can be secured. Thereby, the installation work of the communication signal line in the wiring box is facilitated, and the workability is improved.

本発明の実施例2であるエレベータ制御装置について、図5および図6(a)〜(c)を用いて説明する。   An elevator control apparatus that is Embodiment 2 of the present invention will be described with reference to FIGS. 5 and 6A to 6C.

図5は、本実施例2のエレベータ制御装置の外観を示す。なお、図5は、空冷用の吸気口や操作スイッチおよび計器類などが設けられるエレベータ制御装置の前面側を示し、かつエレベータ制御装置の各制御盤の扉あるいは前面蓋が閉じられた状態を示す。   FIG. 5 shows an appearance of the elevator control apparatus according to the second embodiment. FIG. 5 shows the front side of an elevator control device provided with air-cooling air inlets, operation switches, instruments, and the like, and shows a state in which the door or front cover of each control panel of the elevator control device is closed. .

図5に示すように、本実施例2のエレベータ制御装置1は、4台の制御盤、すなわち、建屋電源から電力を受電する受電回路部を備える受電盤2と、電源用のフィルタ回路部を備えるフィルタ盤3と、建屋電源からの電力を可変電圧可変周波数の交流電力に変換する電力変換回路部を備える主回路盤41と、電力変換回路部を制御したり外部機器と通信したりする制御回路部を備える信号盤5とから構成される。各制御盤において、各回路部は各筐体内に収納される。受電盤2、フィルタ盤3、主回路盤41および信号盤5は、この順に、エレベータ制御装置1の前面側に向かって右側から、横一列に並設される。   As shown in FIG. 5, the elevator control device 1 according to the second embodiment includes four control panels, that is, a power receiving panel 2 including a power receiving circuit unit that receives power from a building power source, and a filter circuit unit for the power source. Filter panel 3 provided, main circuit board 41 including a power conversion circuit unit that converts power from a building power source into AC power of variable voltage and variable frequency, and control for controlling the power conversion circuit unit and communicating with external devices It is comprised from the signal board 5 provided with a circuit part. In each control panel, each circuit unit is housed in each housing. The power receiving board 2, the filter board 3, the main circuit board 41, and the signal board 5 are arranged in parallel in this order from the right side toward the front side of the elevator control device 1.

本実施例2のエレベータ制御装置1は、巻上機の電動機を駆動するための電力が実施例1の約半分というように、実施例1よりも出力電力が小さいため、図5に示すように、主回路盤は1台である。さらに、エレベータ制御装置1が扱う電力に応じて、受電盤2や信号盤5は小型化され、本実施例2では受電盤2や信号盤5の各幅が実施例1の半分程度となる。同様にフィルタ盤3もフィルタ回路部を一個として小型化されるが、本実施例2においては、実施例1と同様のフィルタ回路部31を用いて、フィルタ盤3の高さを約半分にする。   As shown in FIG. 5, the elevator control apparatus 1 according to the second embodiment has a lower output power than the first embodiment such that the power for driving the motor of the hoisting machine is about half that of the first embodiment. The number of main circuit boards is one. Furthermore, the power receiving panel 2 and the signal board 5 are downsized according to the electric power handled by the elevator control device 1, and in the second embodiment, each width of the power receiving board 2 and the signal board 5 is about half that of the first embodiment. Similarly, the filter panel 3 is also reduced in size by using one filter circuit unit. In the second embodiment, the filter circuit unit 31 similar to that of the first embodiment is used to reduce the height of the filter panel 3 to about half. .

なお、フィルタ回路部の寸法や形状を変更することにより、フィルタ盤3も幅を狭くして高さは受電盤2などと同じ高さにしてもよい。これにより、フィルタ盤3の接地面積を低減できる。   Note that the filter panel 3 may be narrowed by changing the dimensions and shape of the filter circuit section so that the height thereof is the same as that of the power receiving panel 2 or the like. Thereby, the ground contact area of the filter panel 3 can be reduced.

図5に示すように、受電盤2、フィルタ盤3、主回路盤41および信号盤5の各直下部には、それぞれ配線箱62,63,64および65が設置される。各制御盤間およびエレベータ制御装置外への電力線は、これら配線箱内を通して敷設される。受電用の電力線は、受電盤2下の配線箱62の図中右側の露出側面からエレベータ制御装置外へ取り出され、図示しない配線ダクトや配線管などを用いて建屋電源まで敷設される。また、主回路盤41の出力用の電力線は、図示されないが、信号盤5下の配線箱65の図中左側の露出側面からエレベータ制御装置1外へ取り出され、配線ダクトや配線管などを用いて巻上機の電動機まで敷設される。   As shown in FIG. 5, wiring boxes 62, 63, 64 and 65 are installed immediately below the power receiving panel 2, the filter panel 3, the main circuit board 41 and the signal board 5, respectively. The power lines between the control panels and to the outside of the elevator control device are laid through the wiring boxes. The power line for power reception is taken out of the elevator control device from the exposed side surface on the right side of the wiring box 62 under the power receiving panel 2 and laid to the building power source using a wiring duct or a wiring pipe (not shown). Further, although not shown, the power line for output of the main circuit board 41 is taken out of the elevator control device 1 from the exposed side surface on the left side of the wiring box 65 under the signal board 5, and uses a wiring duct, a wiring pipe, or the like. It is laid down to the hoisting motor.

本実施例2のエレベータ制御装置の回路構成は、図3において、主遮断器20から分岐する2系統の一方を削除したもの、すなわち、電磁接触器22、端子台73、フィルタ回路部32、端子台76、端子台76に接続される電力変換回路部10、この電力変換回路部に接続されるリアクトル40および端子台77を削除したものに相当する。なお、本実施例2においては、図4に示すコンバータ101を、電力回生機能を備えないダイオード整流回路に置き換えても良い。   The circuit configuration of the elevator control apparatus according to the second embodiment is obtained by removing one of the two systems branched from the main circuit breaker 20 in FIG. 3, that is, the electromagnetic contactor 22, the terminal block 73, the filter circuit unit 32, and the terminal. This corresponds to the base 76, the power conversion circuit unit 10 connected to the terminal block 76, the reactor 40 connected to the power conversion circuit unit, and the terminal block 77. In the second embodiment, the converter 101 shown in FIG. 4 may be replaced with a diode rectifier circuit that does not have a power regeneration function.

次に、本実施例2のエレベータ制御装置における電力線の敷設について、図6(a)〜(c)を参照しながら説明する。なお、図6(a)は、エレベータ制御装置の前面側を示し、かつ、配線の状態を分かりやすくするため扉あるいは蓋が除かれた状態を示す。図6(b)は、エレベータ制御装置の前面側の反対側、すなわち背面側を示し、かつ、同様に扉あるいは蓋が除かれた状態を示す。図6(c)は、図6(a)における断面B−B’の矢視図である。   Next, the laying of power lines in the elevator control apparatus according to the second embodiment will be described with reference to FIGS. FIG. 6A shows the front side of the elevator control device and shows a state in which a door or a lid is removed for easy understanding of the wiring state. FIG. 6B shows the opposite side of the front side of the elevator control device, that is, the back side, and shows a state where the door or the lid is similarly removed. FIG. 6C is an arrow view of a cross section B-B ′ in FIG.

図6(a)に示すように、受電盤2の前面側において、主遮断器20は上端側に位置し、端子台72は下端側に位置する。また、端子台72の直上には、電磁接触器21が、端子台72に隣接する。なお、電磁接触器21は、受電盤2の高さ方向において、下方、かつ主遮断器20と端子台72との間に位置する。また、主遮断器20の動作状態を視認できるように、受電盤2の前面側の扉または蓋は開口部を有しても良い。   As shown in FIG. 6A, on the front side of the power receiving panel 2, the main circuit breaker 20 is located on the upper end side, and the terminal block 72 is located on the lower end side. The electromagnetic contactor 21 is adjacent to the terminal block 72 immediately above the terminal block 72. The electromagnetic contactor 21 is located below and between the main circuit breaker 20 and the terminal block 72 in the height direction of the power receiving panel 2. Further, the door or lid on the front side of the power receiving panel 2 may have an opening so that the operating state of the main circuit breaker 20 can be visually recognized.

また、図6(a)が示すように、フィルタ盤3内には、一台のフィルタ回路部31が設けられる。フィルタ回路部31は、その高さ方向すなわちフィルタ盤3の高さ方向において、フィルタ回路部31の一端(入力端子)および他端(出力端子)がこの順で上下に位置するとともに、フィルタ盤3の前面側に位置するように、フィルタ盤3において設置される。   Further, as shown in FIG. 6A, a single filter circuit unit 31 is provided in the filter panel 3. The filter circuit unit 31 has one end (input terminal) and the other end (output terminal) of the filter circuit unit 31 positioned vertically in this order in the height direction, that is, the height direction of the filter panel 3, and the filter panel 3 It is installed in the filter panel 3 so as to be located on the front side.

さらに、図6(a)が示すように、主回路盤41内において、電力変換回路部10は、その上端が主回路盤41の上端側に隣接するように設置され、リアクトル40および端子台74は電力回路部10の下方において、主回路盤41の下端側に隣接するように設置される。また、主回路盤41の前面側において、リアクトル40および端子台74は、この順で右左に横一列に並設される。すなわち、フィルタ盤31と端子台74との間には、主回路盤41のリアクトル40が位置する。   Further, as shown in FIG. 6A, the power conversion circuit unit 10 is installed in the main circuit board 41 so that the upper end thereof is adjacent to the upper end side of the main circuit board 41, and the reactor 40 and the terminal block 74. Is installed below the power circuit unit 10 so as to be adjacent to the lower end side of the main circuit board 41. In addition, on the front side of the main circuit board 41, the reactor 40 and the terminal block 74 are arranged side by side in a horizontal row on the right and left in this order. That is, the reactor 40 of the main circuit board 41 is located between the filter board 31 and the terminal block 74.

なお、端子台72,74およびフィルタ回路部31の一端および他端は、各々、交流3相分の端子すなわち3個の端子を備える。そして、この3個の端子は、各制御盤の幅方向に横一列に並ぶように配置される。   Note that one end and the other end of the terminal blocks 72 and 74 and the filter circuit unit 31 are each provided with terminals for three phases of AC, that is, three terminals. The three terminals are arranged in a horizontal row in the width direction of each control panel.

上記のようなエレベータ制御装置1の前面側において、端子台72とフィルタ回路部31の一端は、端子台72とフィルタ回路部31の一端との間に敷設される電力線によって、電気的に接続される。また、同前面側において、フィルタ回路部31の他端と端子台74は、フィルタ回路部31の他端と端子台74との間に敷設される電力線によって、電気的に接続される。   On the front side of the elevator control device 1 as described above, one end of the terminal block 72 and the filter circuit unit 31 is electrically connected by a power line laid between the terminal block 72 and one end of the filter circuit unit 31. The Further, on the front side, the other end of the filter circuit unit 31 and the terminal block 74 are electrically connected by a power line laid between the other end of the filter circuit unit 31 and the terminal block 74.

端子台72に接続される電力線は、受電盤2内を下方へ伸び、配線箱62内で曲げられ、配線箱62内を通って、さらに配線箱63内を通ると共に配線箱63内で曲げられ、受電盤2側のフィルタ盤3の筐体側面に沿ってフィルタ盤3内を上方へ伸びて、フィルタ回路部31の一端に接続される。   The power line connected to the terminal block 72 extends downward in the power receiving panel 2, is bent in the wiring box 62, passes through the wiring box 62, further passes through the wiring box 63 and is bent in the wiring box 63. The filter board 3 extends upward along the side surface of the housing of the filter board 3 on the power receiving board 2 side and is connected to one end of the filter circuit unit 31.

フィルタ回路部31の他端に接続される電力線は、フィルタ盤3内を下方へ伸び、配線箱63内を通ると共に配線箱63内で曲げられ、さらに配線箱64内を通ると共に配線箱64内で曲げられ、主回路盤41内を上方へ伸びて、端子台74に接続される。   The power line connected to the other end of the filter circuit section 31 extends downward in the filter panel 3, passes through the wiring box 63 and is bent in the wiring box 63, and further passes through the wiring box 64 and in the wiring box 64. And is extended upward in the main circuit board 41 and connected to the terminal block 74.

なお、本実施例2においても、実施例1と同様に、電力線として、絶縁被覆も含めて直径20〜40mmの電力ケーブルが適用される。   In the second embodiment, as in the first embodiment, a power cable having a diameter of 20 to 40 mm including the insulation coating is applied as the power line.

上述したように、端子台72,74およびフィルタ回路部31の一端および他端がエレベータ制御装置1の前面側に配置されているので、制御盤間を接続する電力線はエレベータ制御装置1の前面側において接続され、図6(c)に示すように、各配線箱内において、エレベータ制御装置1の前面側寄りに敷設される。これにより、電力線を、配線箱内において背面側と前面側との間に敷設するような作業が低減されたり不要になったりするとともに、各配線箱内にスペースが確保され、電力線の敷設作業が容易になる。   As described above, since the terminal blocks 72 and 74 and one end and the other end of the filter circuit unit 31 are arranged on the front side of the elevator control device 1, the power line connecting the control panels is on the front side of the elevator control device 1. 6 and is laid near the front side of the elevator control device 1 in each wiring box as shown in FIG. As a result, the work of laying the power line between the back side and the front side in the wiring box is reduced or unnecessary, space is secured in each wiring box, and the laying work of the power line is performed. It becomes easy.

また、主回路盤41において、端子台74とフィルタ盤3との間には、リアクトル40が介在する。すなわち、端子台74は、主回路盤41において、主回路盤41の筐体側面の内、フィルタ盤3とは反対側の筐体側面により近く位置する。このため、端子台74はフィルタ盤3から横方向に離れているので、フィルタ回路部31の他端に接続される電力線は、配線箱64内において比較的大きな曲率半径で曲げて端子台74に接続することができる。従って、配線箱内での電力線の制御盤間敷設作業が容易になり、敷設作業の作業性が向上する。   In the main circuit board 41, the reactor 40 is interposed between the terminal block 74 and the filter board 3. That is, in the main circuit board 41, the terminal block 74 is located closer to the side of the casing opposite to the filter board 3 in the casing side of the main circuit board 41. For this reason, since the terminal block 74 is laterally separated from the filter panel 3, the power line connected to the other end of the filter circuit section 31 is bent with a relatively large radius of curvature in the wiring box 64 to the terminal block 74. Can be connected. Therefore, the work for laying the power lines between the control panels in the wiring box is facilitated, and the workability of the laying work is improved.

次に、図6(b)に示すように、受電用の端子台71は、受電盤2の背面側において、受電盤2の高さ方向の中央付近に位置する。また、端子台75は、主回路盤41の背面側の下端部内において、主回路盤41の筐体側面の内、フィルタ盤3側の筐体側面により近く位置し、かつリアクトル40に対向する。   Next, as shown in FIG. 6B, the power receiving terminal block 71 is located near the center of the power receiving board 2 in the height direction on the back side of the power receiving board 2. Further, the terminal block 75 is located closer to the housing side surface of the main circuit board 41 on the filter board 3 side in the lower end portion on the back side of the main circuit board 41, and faces the reactor 40.

なお、端子台71,75は、各々、交流3相分の端子すなわち3個の端子を備える。そして、この3個の端子は、各制御盤の幅方向に横一列に並ぶように配置される。   Note that each of the terminal blocks 71 and 75 includes terminals for three phases of AC, that is, three terminals. The three terminals are arranged in a horizontal row in the width direction of each control panel.

図6(b)に示すように、建屋電源81からの電力線は、配線箱62の露出側面から配線箱62内へ引き込まれ、配線箱62内で曲げられて、受電盤2内において受電盤2の高さ方向に伸び、端子台71に接続される。なお、本実施例2のエレベータ制御装置1は実施例1よりも扱う電力が小さいため、端子台71には、一相当たり1本(三相で計3本)の電力線が接続される。端子台75に接続される電力線は、主回路盤41内で下方へ伸び、配線箱64内で曲げられ、配線箱64,65を通って、配線箱65の側面から外部へ取り出される。また、配線箱65から取り出された電力線は、エレベータ制御装置1と共に機械室内に設置される巻上機の電動機に接続される。   As shown in FIG. 6B, the power line from the building power supply 81 is drawn into the wiring box 62 from the exposed side surface of the wiring box 62, bent in the wiring box 62, and within the power receiving board 2, the power receiving board 2. And is connected to the terminal block 71. Since the elevator control device 1 according to the second embodiment handles less power than the first embodiment, one power line per phase (three in total for three phases) is connected to the terminal block 71. The power line connected to the terminal block 75 extends downward in the main circuit board 41, is bent in the wiring box 64, passes through the wiring boxes 64 and 65, and is taken out from the side surface of the wiring box 65 to the outside. Further, the power line taken out from the wiring box 65 is connected to the motor of the hoisting machine installed in the machine room together with the elevator control device 1.

上述したように、端子台71,75がエレベータ制御装置1の背面側に配置されているので、建屋電源および巻上機用の電動機、すなわち外部と、制御盤との間を接続する電力線は、エレベータ制御装置1の背面側において接続され、図6(c)に示すように、各配線箱内において、エレベータ制御装置1の背面側寄りに敷設される。これにより、電力線を、配線箱内において背面側と前面側との間に敷設するような作業が低減されたり不要になったりするとともに、各配線箱内にスペースが確保され、電力線の敷設作業が容易になる。   As described above, since the terminal blocks 71 and 75 are arranged on the back side of the elevator control device 1, the electric power for connecting the building power source and the hoisting machine, that is, the outside and the control panel, It is connected on the back side of the elevator control device 1 and is laid near the back side of the elevator control device 1 in each wiring box as shown in FIG. As a result, the work of laying the power line between the back side and the front side in the wiring box is reduced or unnecessary, space is secured in each wiring box, and the laying work of the power line is performed. It becomes easy.

また、端子台71は、受電盤2の高さ方向の中央付近に位置するため、配線箱62の側面から引き込まれる電力線は、配線箱62内において比較的大きな曲率半径で曲げて端子台71に接続することができる。さらに、端子台75は、主回路盤41内においてフィルタ盤3側の筐体側面に隣接する。すなわち、端子台75は、主回路盤41の筐体側面の内、電力線が巻上機へ向かって引き出される配線箱65の側面側とは反対側における筐体側面により近く位置する。このため、端子台75に接続される電力線は、配線箱64内で曲げられた後、配線箱65内を水平方向へ伸びるように敷設される。これにより、電力線は、比較的大きな曲率半径で曲げて端子台74に接続することができる。従って、配線箱内での電力線の盤と外部間敷設作業が容易になり、敷設作業の作業性が向上する。   Further, since the terminal block 71 is located near the center in the height direction of the power receiving panel 2, the power line drawn from the side surface of the wiring box 62 is bent at a relatively large radius of curvature in the wiring box 62 to the terminal block 71. Can be connected. Further, the terminal block 75 is adjacent to the side surface of the housing on the filter board 3 side in the main circuit board 41. That is, the terminal block 75 is located closer to the side of the casing on the side opposite to the side of the wiring box 65 from which the power line is drawn out toward the hoisting machine among the side of the casing of the main circuit board 41. For this reason, the power line connected to the terminal block 75 is laid so as to extend in the horizontal direction in the wiring box 65 after being bent in the wiring box 64. Thereby, the power line can be bent with a relatively large radius of curvature and connected to the terminal block 74. Therefore, the work of laying between the power line board and the outside in the wiring box is facilitated, and the workability of the laying work is improved.

図6(c)に示すように、受電盤2とフィルタ盤3との間の電力線、フィルタ盤3と主回路盤41との間の電力線はエレベータ制御装置1の前面寄りの位置に敷設され、建屋電源と受電盤2との間の電力線、主回路盤41と電動機との間の電力線はエレベータ制御装置の背面寄りに敷設される。このため、配線箱内における電力線の交差を低減あるいはなくすことができるので、作業性が向上すると共に、配線箱の高さを低減することができる。   As shown in FIG. 6C, the power line between the power receiving panel 2 and the filter panel 3 and the power line between the filter panel 3 and the main circuit board 41 are laid at a position near the front surface of the elevator control device 1, The power line between the building power source and the power receiving panel 2 and the power line between the main circuit board 41 and the motor are laid near the back of the elevator control device. For this reason, since the intersection of the power lines in the wiring box can be reduced or eliminated, the workability is improved and the height of the wiring box can be reduced.

なお、図2(c)に示すように、電力線がエレベータ制御装置の前面側寄りおよび背面側寄りに敷設されることにより、配線箱65内において、信号盤5に接続される通信線用のスペースを広く確保できる。これにより、配線箱内における通信線の敷設作業が容易化され、作業性が向上する。   As shown in FIG. 2C, the power line is laid near the front side and the back side of the elevator control device, so that the space for the communication line connected to the signal board 5 in the wiring box 65 is obtained. Can be secured widely. Thereby, the installation work of the communication line in a wiring box is facilitated, and workability | operativity improves.

For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.

例えば、上述したような電力線の敷設構成を、エレベータ制御装置1の前面側および背面側の一方のみに適用しても、同様の効果を得ることができる。また、エレベータ制御装置は、任意の複数台の制御盤からなるもので良い。   For example, the same effect can be obtained even when the power line laying configuration as described above is applied only to one of the front side and the rear side of the elevator control device 1. Further, the elevator control device may be composed of a plurality of arbitrary control panels.
