Description

本発明は、強制空冷部を備える制御装置に関する。   The present invention relates to a control device including a forced air cooling unit.

電力変換器において使用される半導体スイッチング素子から発生する熱を放熱するために、強制空冷が用いられる。強制空冷の構成としては、例えば特許文献１のように前面から吸気して背面で折り返して前面に排気するものがある。しかし、この構成では、放熱すべき熱量が大きな場合、空気への放熱面積を増加させるために放熱フィンの間隔を狭くすると、風の折り返し部分での圧力損失が大きくなる。また、特許文献２の図９のように、前面から吸気して背面で上方に曲げて排気する２台の制御盤を背中合わせに配置するものがある。しかし、この場合でも排気部分のもう一方の制御装置の存在により圧力損失が増大するため、風速を増加させることが難しく冷却効率が低くなる。   Forced air cooling is used to dissipate heat generated from the semiconductor switching elements used in the power converter. As a configuration of forced air cooling, for example, as disclosed in Patent Document 1, there is one that sucks air from the front surface, turns back at the back surface, and exhausts air to the front surface. However, in this configuration, when the amount of heat to be radiated is large, if the distance between the radiating fins is narrowed in order to increase the heat radiating area to the air, the pressure loss at the folded portion of the wind increases. In addition, as shown in FIG. 9 of Patent Document 2, there is one in which two control panels that suck air from the front side and bend upward at the back side and exhaust the gas are arranged back to back. However, even in this case, since the pressure loss increases due to the presence of the other control device in the exhaust portion, it is difficult to increase the wind speed and the cooling efficiency is lowered.

そのため、電力容量の大きい変換器では、１台または非特許文献１の図３のように複数台の制御盤からなる制御盤列における強制空冷部を備える制御盤の前面から吸気して背面に排気することが多い。このような場合、非特許文献２に記載の並列駆動制御装置のように、２列の制御盤列を並べて配置すると、一方の制御盤列における強制空冷部を備える制御盤の発熱によって温度上昇した排気を、他方の列における強制空冷部を備える制御盤が吸気する。このため、他方の制御盤列の制御盤の半導体スイッチング素子の方が温度が高くなり、特性の不均等や寿命の不均等が生じる。そのため、一方の制御盤列の制御盤の排気が他方の制御盤列の制御盤に影響を及ぼさないように、両制御盤列の間隔を広くすることが必要となり、制御装置の設置場所が増大する。   Therefore, in a converter having a large power capacity, one unit or a non-patent document 1 as shown in FIG. 3 is sucked from the front side of a control panel having a forced air cooling unit in a control panel row composed of a plurality of control panels and exhausted to the rear side. Often done. In such a case, when the two control panel rows are arranged side by side as in the parallel drive control device described in Non-Patent Document 2, the temperature rises due to the heat generated by the control panel including the forced air cooling unit in one control panel row. Exhaust air is taken in by a control panel having a forced air cooling unit in the other row. For this reason, the temperature of the semiconductor switching element of the control panel in the other control panel row becomes higher, resulting in uneven characteristics and uneven life. Therefore, it is necessary to widen the space between both control panel rows so that the exhaust of the control panel of one control panel row does not affect the control panel of the other control panel row, and the installation place of the control device increases. To do.

本発明が解決しようとする課題は、強制空冷部を有する制御盤を複数並置した制御装置において、各制御盤の冷却効率の低下を抑制することである。   The problem to be solved by the present invention is to suppress a decrease in cooling efficiency of each control panel in a control device in which a plurality of control panels having forced air cooling units are juxtaposed.

並置される複数の制御盤列の各々において、強制空冷部を備える制御盤の吸気面が、各制御盤列の間の空間に面し、排気面が吸気面の反対側に位置する。   In each of the plurality of juxtaposed control panel rows, the intake surface of the control panel provided with the forced air cooling unit faces the space between the control panel rows, and the exhaust surface is located on the opposite side of the intake surface.

本発明によれば、一つの制御盤の発熱により温度上昇した排気が、他の制御盤に吸気されることが防止されるので、冷却効率の低下が抑制できる。   According to the present invention, it is possible to prevent the exhaust gas whose temperature has risen due to the heat generated by one control panel from being sucked into another control panel, so that a decrease in cooling efficiency can be suppressed.

以下本発明の詳細について図面を用いながら説明する。   The details of the present invention will be described below with reference to the drawings.

まず、本発明による制御装置に用いられる回路構成を図８に示す。本図に示すように、交流電源９０から、受電回路部１３および２セット並列接続した変換器の主回路部１１Ａおよび１１Ｂを介して、負荷を駆動するためのモータ９２に所望の電力を供給する。また、主回路部は信号回路部１２により負荷の状態に応じて制御される。   First, FIG. 8 shows a circuit configuration used in the control device according to the present invention. As shown in the figure, desired power is supplied from an AC power supply 90 to a motor 92 for driving a load through a power receiving circuit unit 13 and two sets of converter main circuit units 11A and 11B connected in parallel. . The main circuit unit is controlled by the signal circuit unit 12 according to the state of the load.

受電回路部１３は、過電流保護および電源投入のための開閉器１３０１とフィルタ回路１３０２とで構成され、主回路部１１Ａおよび１１Ｂは、順変換部１１０１，平滑コンデンサ１１０３および逆変換部１１０２で構成されている。なお、図８に示した回路構成は一例に過ぎず、この他に変圧器が接続されたり、モータ側にリアクトルが接続されたりしても良い。   The power receiving circuit unit 13 includes a switch 1301 and a filter circuit 1302 for overcurrent protection and power-on, and the main circuit units 11A and 11B include a forward conversion unit 1101, a smoothing capacitor 1103, and an inverse conversion unit 1102. Has been. Note that the circuit configuration shown in FIG. 8 is merely an example, and a transformer may be connected to the circuit, or a reactor may be connected to the motor side.

図１は、本発明の第１の実施例である制御装置を示す。本図においては、強制空冷部を備える制御盤を含む複数の制御盤からなる制御盤列が２列略平行に並置される場合の各制御盤の配置を示すと共に、矢印で強制空冷の風向きを示す。なお、Ｃ−Ｃ′断面の構成については後述する。   FIG. 1 shows a control apparatus according to a first embodiment of the present invention. This figure shows the layout of each control panel in the case where two control panel rows comprising a plurality of control panels including a control panel having a forced air cooling unit are juxtaposed in parallel, and the direction of forced air cooling is indicated by an arrow. Show. The configuration of the CC ′ cross section will be described later.

２列の制御盤列の内、第１の制御盤列１においては、強制空冷部を有する主回路部１１Ａ，主回路部を制御するための信号回路部１２，強制空冷部を有する主回路部１１Ｂおよび受電回路部１３が、この順番で列状に配置される。これらの回路部は、それぞれ、筐体に納められて制御盤を構成する。制御盤列１において、主回路部１１Ａおよび１１Ｂを有する制御盤は、いずれも、２列の制御盤列１，２の間の空間に面する吸気面から吸気し、各制御盤において吸気面の反対側に位置する排気面から排気する方向に冷却風を吹かせている。そのため、主回路部１１Ａおよび１１Ｂが納められる制御盤の吸気面側の扉には吸気穴８３が設けられかつ吸気フィルタ８４が取り付けられる。また、図示されていないが、排気面側の扉には、排気穴が設けられている。なお、本実施例において、信号回路部１２および受電回路部１３は、主にコンデンサ，リアクトルなどの受動回路素子や機械的開閉器から構成されるため、強制空冷部を備えていない。   Of the two control panel rows, in the first control panel row 1, the main circuit unit 11A having the forced air cooling unit, the signal circuit unit 12 for controlling the main circuit unit, and the main circuit unit having the forced air cooling unit 11B and the power receiving circuit unit 13 are arranged in a row in this order. Each of these circuit units is housed in a casing to constitute a control panel. In the control panel row 1, the control panel having the main circuit portions 11 </ b> A and 11 </ b> B both sucks air from the intake surface facing the space between the two control panel rows 1 and 2. Cooling air is blown in the direction of exhaust from the exhaust surface located on the opposite side. Therefore, an intake hole 83 is provided in the door on the intake surface side of the control panel in which the main circuit portions 11A and 11B are accommodated, and an intake filter 84 is attached. Although not shown, the door on the exhaust surface side is provided with an exhaust hole. In the present embodiment, the signal circuit unit 12 and the power receiving circuit unit 13 are mainly composed of passive circuit elements such as capacitors and reactors and mechanical switches, and therefore do not include a forced air cooling unit.

第２の制御盤列２においても、強制空冷部を有する主回路部２１Ａ，主回路部を制御するための信号回路部２２，強制空冷部を有する主回路部２１Ｂおよび受電回路部２３が、この順番で列状に配置される。これらの回路部も、それぞれ、筐体に納められて制御盤を構成している。制御盤列２は制御盤列１に略平行に並置され、主回路部２１Ａを有する制御盤，信号回路部２２を有する制御盤，主回路部２１Ｂを有する制御盤および受電回路部２３を有する制御盤は、それぞれ制御盤列１における主回路部１１Ａを有する制御盤，信号回路部１２を有する制御盤，主回路部１１Ｂを有する制御盤および受電回路部１３を有する制御盤と対向している。制御盤列２においても、主回路部２１Ａおよび２１Ｂが納められる制御盤は、いずれも、２列の制御盤列１，２の間の空間に面する吸気面から吸気し、各制御盤において吸気面の反対側に位置する排気面から排気する方向に冷却風を吹かせている。そのため、主回路部２１Ａおよび２１Ｂが納められる制御盤の排気面側の扉には排気穴８５が設けられる。また、図示されていないが、制御盤列１の主回路部１１Ａおよび１１Ｂを有する制御盤と同様に、吸気面側の扉には吸気穴が設けられ、かつ吸気フィルタが取り付けられている。なお、信号回路部１２および受電回路部１３と同様に、信号回路部２２および受電回路部２３は、受動回路素子や機械的開閉器から構成されるため、強制空冷部を備えていない。   Also in the second control panel row 2, the main circuit unit 21A having the forced air cooling unit, the signal circuit unit 22 for controlling the main circuit unit, the main circuit unit 21B having the forced air cooling unit, and the power receiving circuit unit 23 are Arranged in order. Each of these circuit units is also housed in a casing to constitute a control panel. The control panel row 2 is juxtaposed substantially in parallel with the control panel row 1, and includes a control panel having a main circuit unit 21A, a control panel having a signal circuit unit 22, a control panel having a main circuit unit 21B, and a control unit having a power receiving circuit unit 23. The panels face the control panel having the main circuit unit 11A, the control panel having the signal circuit unit 12, the control panel having the main circuit unit 11B, and the control panel having the power receiving circuit unit 13 in the control panel row 1, respectively. In the control panel row 2 as well, the control panel in which the main circuit portions 21A and 21B are housed intakes air from the intake surface facing the space between the two control panel rows 1 and 2, and the intake air in each control panel. Cooling air is blown in the direction of exhaust from the exhaust surface located on the opposite side of the surface. Therefore, an exhaust hole 85 is provided in the door on the exhaust surface side of the control panel in which the main circuit portions 21A and 21B are accommodated. Although not shown, like the control panel having the main circuit portions 11A and 11B of the control panel row 1, the door on the intake surface side is provided with an intake hole and an intake filter is attached. Note that, similarly to the signal circuit unit 12 and the power receiving circuit unit 13, the signal circuit unit 22 and the power receiving circuit unit 23 include passive circuit elements and mechanical switches, and thus do not include a forced air cooling unit.

互いに対向する二つの制御盤、例えば主回路部１１Ａが納められる制御盤と主回路部２１Ａが納められる制御盤は、出力電力などの電気的仕様が同じである。このため、両制御盤においては、同じ電気部品、および同じ寸法仕様の筐体が用いられ、電気部品は筐体内において同様に配列及び配線されている。扉を開けた時に見える筐体内の様子については、一方の制御盤の吸気側扉を開いた時に見える電気部品の配列および配線の様子と、他方の制御盤の排気側扉を開いた時に見える電気部品の配列および配線の様子とが同様である。従って、両制御盤においては、同じ電気部品の配列に対して、吸気側扉と排気側扉を取り付ける位置が互いに逆になり、また筐体内における冷却風の向きが互いに反対方向となる。なお、信号回路部１２および２２，主回路部１１Ｂと２１Ｂ，受電回路部１３と２３についても、同様である。ただし、信号回路部または受電回路部が納められる制御盤については、制御盤列１においては排気側扉が設けられず、制御盤列２においては吸気側扉が設けられていない。   Two control panels facing each other, for example, the control panel in which the main circuit unit 11A is accommodated and the control panel in which the main circuit unit 21A is accommodated have the same electrical specifications such as output power. For this reason, both control panels use the same electrical components and casings having the same dimensional specifications, and the electrical components are similarly arranged and wired in the casings. As for the inside of the housing that can be seen when the door is opened, the arrangement and wiring of the electrical parts that can be seen when the intake side door of one control panel is opened, and the electrical that can be seen when the exhaust side door of the other control panel is opened The arrangement of components and the state of wiring are the same. Therefore, in both control panels, the positions where the intake side door and the exhaust side door are attached are opposite to each other with respect to the same arrangement of electrical components, and the directions of the cooling air in the casing are opposite to each other. The same applies to the signal circuit units 12 and 22, the main circuit units 11B and 21B, and the power receiving circuit units 13 and 23. However, regarding the control panel in which the signal circuit unit or the power receiving circuit unit is accommodated, the control panel row 1 is not provided with the exhaust side door, and the control panel row 2 is not provided with the intake side door.

本実施例においては、制御盤列１および２の受電回路部側端部に隣接して配線ダクト９１が設けられ、建屋電源へ接続される電線が、制御盤が載置される台座１４および２４を通って受電回路部１３および２３に接続されている。   In this embodiment, a wiring duct 91 is provided adjacent to the power receiving circuit side ends of the control panel rows 1 and 2, and the wires 14 and 24 on which the control panel is placed are connected to the building power source. The power receiving circuit sections 13 and 23 are connected to each other.

本実施例のような制御盤の配置および冷却風の方向とすることで、一方の制御盤列における制御盤の発熱により温度上昇した排気が、他方の制御盤列における制御盤に吸気されることが防止される。すなわち、両制御盤列における制御盤が共に、制御盤の発熱により温度上昇していない比較的低温の空気により十分冷却される。従って、制御盤列１における主回路部１１Ａ，１１Ｂの半導体スイッチング素子と、制御盤列２における主回路部２１Ａ，２１Ｂの半導体スイッチング素子とで、温度上昇，寿命の低下，温度や寿命の不均等を防止することができる。また、制御盤列１と制御盤列２との間で、吸気に対する排気の影響が低減するので、両制御盤列の間隔を低減することができる。このため、制御盤列１，２を設置する装置室の面積を低減することができる。   With the arrangement of the control panel and the direction of the cooling air as in this embodiment, the exhaust gas whose temperature has risen due to the heat generated by the control panel in one control panel row is sucked into the control panel in the other control panel row. Is prevented. That is, both control panels in both control panel rows are sufficiently cooled by relatively low temperature air that has not increased in temperature due to heat generated by the control panels. Accordingly, the semiconductor switching elements of the main circuit portions 11A and 11B in the control panel row 1 and the semiconductor switching elements of the main circuit portions 21A and 21B in the control panel row 2 have an increase in temperature, a decrease in life, and uneven temperature and life. Can be prevented. In addition, since the influence of the exhaust on the intake air is reduced between the control panel row 1 and the control panel row 2, the interval between the two control panel rows can be reduced. For this reason, the area of the apparatus room in which the control panel rows 1 and 2 are installed can be reduced.

なお、装置室の塵埃が少ない場合は、吸気フィルタ８４は必ずしも設けなくても良い。その場合には、吸気穴と排気穴を同じ形状とし、吸気側扉と排気側扉を同一のものを用いることができる。   Note that the intake filter 84 is not necessarily provided when the dust in the apparatus chamber is small. In this case, the intake hole and the exhaust hole can have the same shape, and the same intake side door and exhaust side door can be used.

図２は、本発明の第２の実施例である制御装置を示す。図１の実施例と同様に、２列の制御盤列を略並行に並置した場合の各制御盤の配置と強制空冷の風向きを示す。   FIG. 2 shows a control apparatus according to a second embodiment of the present invention. As in the embodiment of FIG. 1, the arrangement of the control panels and the direction of forced air cooling when two control panel rows are juxtaposed in parallel are shown.

図２の実施例において、図１の実施例との違いは次のとおりである。まず、信号回路部１２，２２並びに受電回路部１３，２３が納められる筐体の扉が、いずれも制御盤列間の空間側に位置する。また、主回路部１１Ａ，２１Ｂ，１１Ｂ，２１Ａが納められる制御盤においては、吸気側扉を開いた時に見える電気部品の配列および配線の様子が同様である。また、これら主回路部が納められる制御盤においては、排気側扉を開いた時に見える電気部品の配列および配線の様子が同様である。すなわち、互いに対向する２つの制御盤の組においては、扉も含めた筐体，筐体内の回路部品，回路部品の配列や配線の様子，回路部品の配列に対する風向きなどが同じ仕様の２つの制御盤が、同じ面（主回路部については吸気面）が向かい合うように設置されている。このように、互いに向かい合わせる制御盤の仕様を同一にできるので、制御装置の生産性を損なうことが無い。なお、本実施例における冷却風の方向は図１と同様であり、図１の実施例と同じく、一方の制御盤列における制御盤の発熱により温度上昇した排気が、他方の制御盤列における制御盤に吸気されることが防止される。   The difference between the embodiment of FIG. 2 and the embodiment of FIG. 1 is as follows. First, the doors of the housings in which the signal circuit units 12 and 22 and the power receiving circuit units 13 and 23 are housed are all located on the space side between the control panel rows. Further, in the control panel in which the main circuit portions 11A, 21B, 11B, and 21A are housed, the arrangement of electrical components and the state of wiring that are visible when the intake side door is opened are the same. Further, in the control panel in which these main circuit units are housed, the arrangement of electrical components and the state of wiring that are visible when the exhaust door is opened are the same. In other words, in the two control panel sets facing each other, two controls with the same specifications such as the case including the door, the circuit components in the case, the arrangement of the circuit components and the state of the wiring, the wind direction with respect to the arrangement of the circuit components, etc. The panel is installed so that the same surface (the intake surface for the main circuit part) faces each other. In this way, the specifications of the control panels facing each other can be made the same, so that the productivity of the control device is not impaired. The direction of the cooling air in this embodiment is the same as that in FIG. 1, and as in the embodiment in FIG. 1, the exhaust gas whose temperature has risen due to the heat generated by the control panel in one control panel row is controlled in the other control panel row. Inhalation to the board is prevented.

図３は、本発明の第３の実施例である制御装置を示す。図１，図２の実施例と同様に、２列の制御盤列を略並行に並置した場合の各制御盤の配置と強制空冷の風向きを示す。   FIG. 3 shows a control apparatus according to a third embodiment of the present invention. As in the embodiment of FIGS. 1 and 2, the arrangement of the control panels and the direction of forced air cooling when two control panel rows are juxtaposed in parallel are shown.

本実施例において、制御盤列２は制御盤列１を単純に１８０度回転させて向かい合わせたものとなっている。このため、制御盤列１における主回路部１１Ａ，信号回路部１２，主回路部１１Ｂ，受電回路部１３を筐体に納めた各制御盤は、それぞれ、制御盤列２における受電回路部２３，主回路部２１Ｂ，信号回路部２２，主回路部２１Ａを筐体に納めた各制御盤と対向する。なお、本実施例においては、図１または図２における配線ダクト９１から連続して、制御盤列２に沿って配線ダクトが設けられ、受電回路部２３を建屋電源に接続している。   In the present embodiment, the control panel row 2 is simply the control panel row 1 rotated by 180 degrees and facing each other. For this reason, each control panel in which the main circuit unit 11A, the signal circuit unit 12, the main circuit unit 11B, and the power receiving circuit unit 13 in the control panel row 1 are housed in the casing is respectively connected to the power receiving circuit unit 23 in the control panel row 2, The main circuit unit 21B, the signal circuit unit 22, and the main circuit unit 21A are opposed to each control panel housed in a casing. In this embodiment, a wiring duct is provided along the control panel row 2 continuously from the wiring duct 91 in FIG. 1 or FIG. 2, and the power receiving circuit unit 23 is connected to the building power source.

このように、強制空冷部を備えた主回路部を有する制御盤が、強制空冷部を備えていない制御盤と対向しているので、制御盤列１の制御盤の吸気面と制御盤列２の制御盤の吸気面とが互いに離れて位置する。従って、一方の制御盤列における吸気の状態が、他方の制御盤列における吸気の状態に及ぼす影響が緩和される。従って、制御装置の冷却効率が向上する。   As described above, the control panel having the main circuit section provided with the forced air cooling section is opposed to the control panel not including the forced air cooling section. And the intake surface of the control panel are located away from each other. Therefore, the influence of the intake state in one control panel row on the intake state in the other control panel row is alleviated. Therefore, the cooling efficiency of the control device is improved.

次に、本発明を実施した制御装置における強制空冷部を備えた制御盤の実装構造例を図４〜図６を用いて説明する。   Next, an example of the mounting structure of the control panel provided with the forced air cooling unit in the control apparatus embodying the present invention will be described with reference to FIGS.

図４は主回路部１１Ａを備える制御盤の側面図を示す。本制御盤においては、ヒートパイプ式放熱器により半導体スイッチング素子５１および５２が冷却される。半導体スイッチング素子で発生した熱を、半導体スイッチング素子が取り付けられる受熱部６１，受熱部６１から延びるヒートパイプ６２およびヒートパイプ６２に接触する放熱フィン６３を介して放熱する。吸気用ファンパネル７１に取り付けられた吸気用ファン８１と、排気用ファンパネル７２に取り付けられた排気用ファン８２とにより強制空冷することで、放熱フィン６３から空気へと放熱される。これにより、半導体スイッチング素子５１，５２の温度上昇を抑制する。   FIG. 4 is a side view of a control panel including the main circuit unit 11A. In the present control panel, the semiconductor switching elements 51 and 52 are cooled by a heat pipe radiator. The heat generated in the semiconductor switching element is dissipated through the heat receiving part 61 to which the semiconductor switching element is attached, the heat pipe 62 extending from the heat receiving part 61 and the heat dissipating fins 63 contacting the heat pipe 62. Heat is radiated from the radiation fins 63 to the air by forced air cooling by the intake fan 81 attached to the intake fan panel 71 and the exhaust fan 82 attached to the exhaust fan panel 72. Thereby, the temperature rise of the semiconductor switching elements 51 and 52 is suppressed.

なお、図４の制御盤においては、吸気側に、半導体スイッチング素子５１と端子台５３が位置する。また、排気側に、半導体スイッチング素子５２と平滑コンデンサ５４が位置する。従って、吸気側の扉を開くと、半導体スイッチング素子５１，端子台５３や吸気用ファン８１などの電気部品やこれらの配線の様子が見える。また、排気側の扉を開くと、半導体スイッチング素子５２，平滑コンデンサ５４や排気用ファン８２などの電気部品やこれらの配線の様子が見える。   In the control panel of FIG. 4, the semiconductor switching element 51 and the terminal block 53 are located on the intake side. Further, the semiconductor switching element 52 and the smoothing capacitor 54 are located on the exhaust side. Accordingly, when the door on the intake side is opened, the electrical components such as the semiconductor switching element 51, the terminal block 53, the intake fan 81, and the wiring of these can be seen. Moreover, when the door on the exhaust side is opened, the electrical components such as the semiconductor switching element 52, the smoothing capacitor 54, the exhaust fan 82, and the state of these wirings can be seen.

図４におけるＡ−Ａ′矢視図およびＢ−Ｂ′矢視図をそれぞれ図５および図６に示す。これらの図は、実質、制御盤の扉を開いた時に見える筐体内の様子を示す。図５に示した制御盤の吸気側では、吸気用ファンパネル７１に取り付けられた吸気用ファン８１，半導体スイッチング素子５１，端子台５３が見え、端子台５３に一部隠れてはいるが平滑コンデンサ５４も見える。また、図６に示した制御盤の排気側では、排気用ファンパネル７２に取り付けられた排気用ファン８２，半導体スイッチング素子５２，平滑コンデンサ５４が見える。   The AA ′ arrow view and BB ′ arrow view in FIG. 4 are shown in FIGS. 5 and 6, respectively. These drawings substantially show the inside of the housing that can be seen when the door of the control panel is opened. On the intake side of the control panel shown in FIG. 5, the intake fan 81 attached to the intake fan panel 71, the semiconductor switching element 51, and the terminal block 53 can be seen, and a smoothing capacitor is partially hidden in the terminal block 53. 54 is also visible. Further, on the exhaust side of the control panel shown in FIG. 6, an exhaust fan 82, a semiconductor switching element 52, and a smoothing capacitor 54 attached to the exhaust fan panel 72 can be seen.

図４の制御盤を、図１における制御盤列１の主回路部１１Ａを備える制御盤に適用する場合、図１における制御盤列２の主回路部２１Ａを備える制御盤は、図４において吸気用ファン８１と排気用ファン８２の取り付け位置を取り替えたものとなる。なお、図１において主回路部１１Ｂ，２１Ｂを備える各制御盤の関係も同様である。   When the control panel of FIG. 4 is applied to a control panel including the main circuit portion 11A of the control panel row 1 in FIG. 1, the control panel including the main circuit portion 21A of the control panel row 2 in FIG. The mounting positions of the fan 81 and the exhaust fan 82 are exchanged. In addition, the relationship of each control board provided with the main circuit parts 11B and 21B in FIG. 1 is also the same.

図２および図３の各実施例において、主回路部１１Ａ，１１Ｂ，２１Ａ，２１Ｂを備える各制御盤は、いずれも図４の制御盤が適用される。   2 and 3, the control panel shown in FIG. 4 is applied to each control panel including the main circuit portions 11A, 11B, 21A, and 21B.

なお、吸気用ファンパネル７１と排気用ファンパネル７２とは２種類の部品である必要はなく、同じファンを向きを反対にして取り付けても良い。すなわち、部品を共通化しても良い。   Note that the intake fan panel 71 and the exhaust fan panel 72 do not have to be two types of components, and the same fan may be mounted in opposite directions. That is, parts may be shared.

また、放熱フィン部分の圧力損失が低い場合には、吸気側と排気側のどちらか一方にファンを設置しても良い。例えば、図４の制御盤を、図１における制御盤列１の主回路部１１Ａを備える制御盤に適用し、かつ図１における制御盤列２の主回路部２１Ａを備える制御盤を、図４において吸気用ファン８１と排気用ファン８２の取り付け位置を取り替えたものとした場合、主回路部１１Ａ，２１Ａを有する各制御盤において吸気用ファンだけとすることができる。あるいは、同じ場合において、主回路部１１Ａを有する制御盤では吸気用ファンだけとし、主回路部２１Ａを有する制御盤では吸気用ファンだけとすることができる。   Further, when the pressure loss of the radiating fin portion is low, a fan may be installed on either the intake side or the exhaust side. For example, the control panel of FIG. 4 is applied to a control panel including the main circuit portion 11A of the control panel row 1 in FIG. 1 and the control panel including the main circuit portion 21A of the control panel row 2 in FIG. When the mounting positions of the intake fan 81 and the exhaust fan 82 are changed in FIG. 5, only the intake fan can be provided in each control panel having the main circuit portions 11A and 21A. Alternatively, in the same case, only the intake fan can be provided in the control panel having the main circuit unit 11A, and only the intake fan can be provided in the control panel having the main circuit unit 21A.

図７は本発明の第４の実施例である制御装置を示す。本図においては、４列の制御盤列が円形に近い装置室内に並設される場合の各制御盤の配置と強制空冷の風向きを矢印で示す。   FIG. 7 shows a control apparatus according to a fourth embodiment of the present invention. In the figure, arrows indicate the arrangement of the control panels and the direction of forced air cooling when four control panel rows are arranged side by side in a nearly circular device room.

図７の制御装置においては、４列の制御盤列が、装置室内の中央部の空間を取り囲むようにあるいは挟むように、略矩形状に並置される。第１の制御盤列において主回路部１１Ａおよび１１Ｂを備える各制御盤，第２の制御盤列において主回路部２１Ａおよび２１Ｂを備える各制御盤，第３の制御盤列において主回路部３１Ａおよび３１Ｂを備える各制御盤、並びに第４の制御盤列において主回路部４１Ａおよび４１Ｂを備える各制御盤は、４列の制御盤列によって取り囲まれる空間側に吸気面を有し、この空間側と反対側に排気面を有する。すなわち、各制御盤において、冷却風は、各制御盤列を辺とする矩形の内側から外側に向かって、吹いている。従って、ある制御盤列における制御盤の発熱により温度上昇した排気が、他の制御盤列における制御盤に吸気されることが防止される。   In the control device of FIG. 7, four control panel rows are juxtaposed in a substantially rectangular shape so as to surround or sandwich the space in the center of the device room. Each control panel having main circuit portions 11A and 11B in the first control panel row, each control panel having main circuit portions 21A and 21B in the second control panel row, main circuit portion 31A in the third control panel row, and Each control panel including 31B and each control panel including main circuit portions 41A and 41B in the fourth control panel row have an intake surface on the space side surrounded by the four rows of control panel rows. It has an exhaust surface on the opposite side. That is, in each control panel, the cooling air is blowing from the inside to the outside of a rectangle having each control panel row as a side. Accordingly, the exhaust gas whose temperature has risen due to the heat generated by the control panel in one control panel row is prevented from being sucked into the control panel in another control panel row.

なお、図７の実施例において、受電回路部１３，２３を有する各制御盤は共に各制御盤列を辺とする矩形の１頂点部に位置し、この１頂点部に対向する他の頂点部に受電回路部３３及び４３を有する各制御盤が位置する。このため、これら頂点部を結ぶ対角線に沿って配線ダクト９１を設けて、このような１箇所のダクト内に建屋電源と各受電回路部とを接続する配線を集約することができる。なお、図７では、各受電回路部への配線は、便宜的に、それぞれ１本の破線で示している。   In the embodiment of FIG. 7, each control panel having the power receiving circuit sections 13 and 23 is located at one vertex of a rectangle having each control panel row as a side, and the other vertex that opposes this one vertex. Each control panel having the power receiving circuit portions 33 and 43 is located in the center. For this reason, the wiring duct 91 is provided along the diagonal line which connects these vertex parts, and the wiring which connects a building power supply and each receiving circuit part in such a duct can be collected. In FIG. 7, the wiring to each power receiving circuit unit is indicated by one broken line for convenience.

図９は、本発明の第５の実施例である制御装置を示す。なお、本図は、図１におけるＣ−Ｃ′矢視図に相当する。装置室の天井部には、空調装置の吹出口９３が据え付けられており、その吹出口９３が対向する２台の制御盤の間の空間の上部に位置している。これにより、図９に示すように、温度調整された空気、すなわち制御盤の発熱により温度上昇していない空気を吸気することができる。従って、各制御盤の温度上昇を抑制することができる。   FIG. 9 shows a control apparatus according to a fifth embodiment of the present invention. In addition, this figure is corresponded in CC 'arrow view in FIG. An air outlet 93 of the air conditioner is installed on the ceiling of the apparatus room, and the air outlet 93 is located in the upper part of the space between the two control panels facing each other. As a result, as shown in FIG. 9, the temperature-adjusted air, that is, the air whose temperature has not risen due to the heat generated by the control panel can be sucked. Therefore, the temperature rise of each control panel can be suppressed.

また、図９の実施例において、制御装置の運転状態により発熱量が変化する場合には、運転状態により空調装置を制御することにより、吸気温度を制御することができる。従って、制御装置内部の電気部品、例えば半導体スイッチング素子の温度変化サイクル数を低減することができるので、寿命劣化を抑制することができる。   In the embodiment of FIG. 9, when the heat generation amount changes depending on the operation state of the control device, the intake air temperature can be controlled by controlling the air conditioner according to the operation state. Accordingly, the number of temperature change cycles of the electrical components inside the control device, for example, the semiconductor switching element can be reduced, so that the life deterioration can be suppressed.

なお、上記の実施例に限らず、本発明の技術的思想の範囲内で、種々の実施形態が可能である。例えば、制御盤列数は、２列や４列に限らず、他の複数列でも良い。また、一つの制御盤に含まれる制御盤は、複数台に限らず一台であっても良い。   Note that the present invention is not limited to the above embodiments, and various embodiments are possible within the scope of the technical idea of the present invention. For example, the number of control panel rows is not limited to 2 rows or 4 rows, but may be other multiple rows. Further, the number of control panels included in one control panel is not limited to a plurality, and may be one.
