Description

本発明の実施形態は、ガス絶縁開閉機器等の変電機器などに適用される制御盤用組立式筐体及びその組立方法に関する。   Embodiments described herein relate generally to a control panel assembly-type housing and a method for assembling the control panel, which are applied to a transformer such as a gas-insulated switchgear.

従来より、ガス絶縁開閉機器等の変電機器などに適用される制御盤向け筐体には、組立式と板金筐体と言われる主に２種類の構造が一般的である。   2. Description of the Related Art Conventionally, there are two main types of structures for control panels applied to substation equipment such as gas-insulated switchgear, which are referred to as an assembly type and a sheet metal casing.

組立式の筐体は、柱、屋根、側板等を溶接せずにネジ止めやボルト締結で取り付けるものであるのに対し、板金筐体は、金属板を折り曲げ加工し、溶接によって構成されるものである。   Assembled type housings are attached by screwing or bolt fastening without welding columns, roofs, side plates, etc., whereas sheet metal housings are constructed by bending metal plates and welding It is.

ガス絶縁開閉機器用の制御盤は、電線配線数が多く、補助継電器、メータ類、機器操作スイッチ、機器状態表示灯等の取付部品も多い。従って、制御盤はこれらの重量物の収納に耐えるべく、頑強な構造である板金筐体が採用されていた。   The control panel for gas-insulated switchgear has a large number of electric wires, and there are many mounting parts such as auxiliary relays, meters, device operation switches, and device status indicators. Therefore, a sheet metal housing having a robust structure has been adopted for the control panel to withstand the storage of these heavy objects.

一方、適用される変電機器の定格により要求仕様が異なることから、仕様による制御盤向け筐体サイズも様々な種類があった。   On the other hand, since the required specifications differ depending on the rating of the substation equipment to be applied, there are various types of cabinet sizes for the control panel depending on the specifications.

従来の電圧階級１４５ｋＶガス絶縁開閉装置用制御盤の構成図を図７乃至図１１に示す。   The block diagram of the control panel for the conventional voltage class 145 kV gas insulated switchgear is shown in FIGS.

ガス絶縁開閉装置用制御盤５０では、幅Ｘ９００ｍｍ、高さＹ２２００ｍｍ、奥行きＺ８００ｍｍの筐体１の外側に外扉２、内側に内扉３が取り付けられている。   In the gas insulated switchgear control panel 50, the outer door 2 is attached to the outer side of the casing 1 having a width X 900 mm, a height Y 2200 mm, and a depth Z 800 mm, and the inner door 3 is attached to the inner side.

内扉３には、図７、図８に示すように、故障表示器２７、メータ２８、ベイ・コントロール・ユニット２９、機器操作スイッチ３０、配線用遮断器３１、補助継電器３２、切換スイッチ３３が直接取付けられる。このような重量物を取り付けた内扉３を搭載するため、筐体１は板金が採用される。   As shown in FIGS. 7 and 8, the inner door 3 includes a failure indicator 27, a meter 28, a bay control unit 29, a device operation switch 30, a wiring breaker 31, an auxiliary relay 32, and a changeover switch 33. Mounted directly. In order to mount the inner door 3 to which such a heavy object is attached, the housing 1 is made of sheet metal.

また、図１０に示すように、板金筐体１の正面奥部には、端子台３４及び配線ダクト３５が配置されている。   Further, as shown in FIG. 10, a terminal block 34 and a wiring duct 35 are disposed in the front rear portion of the sheet metal housing 1.

さらに、図１１に示すように、外扉２及び内扉３の開閉方向は同じ方向とされている。   Furthermore, as shown in FIG. 11, the opening and closing directions of the outer door 2 and the inner door 3 are the same direction.

また、図１２は、従来の電圧階級４２０ｋＶガス絶縁開閉装置用制御盤の一例を示すものである。   FIG. 12 shows an example of a control panel for a conventional voltage class 420 kV gas insulated switchgear.

このガス絶縁開閉装置用制御盤６０では、幅Ｘ’１６００ｍｍ、高さＹ２２００ｍｍの筐体１’を用いており、図７に示す１４５ｋＶガス絶縁開閉装置用制御盤５０の２倍の幅とされている。ガス絶縁開閉装置用制御盤６０においても、上述した絶縁開閉装置用制御盤５０と同様の構造が採用されている。   The control panel 60 for gas insulated switchgear uses a casing 1 ′ having a width X ′ of 1600 mm and a height of Y2200 mm, which is twice as wide as the control panel 50 for a 145 kV gas insulated switchgear shown in FIG. Yes. The gas insulated switchgear control panel 60 also has the same structure as that of the insulated switchgear control panel 50 described above.

特開平９−１０７６１０号公報JP-A-9-107610

変電機器、特にガス絶縁開閉機器用の制御盤は電線の配線量が多く、制御部品も多品種に渡り取付けられる。例えば、図７に示したガス絶縁開閉装置用制御盤５０の内扉３には、ベイ・コントロール・ユニット２９や故障表示器２７、メータ２８等が取付けられるため、約２５０ｋｇ以上の重量になる。   Control panels for substation equipment, especially gas-insulated switchgear, have a large amount of wires, and control parts can be installed in a wide variety of products. For example, the bay control unit 29, the failure indicator 27, the meter 28, and the like are attached to the inner door 3 of the gas insulated switchgear control panel 50 shown in FIG.

しかしながら、このガス絶縁開閉装置用制御盤５０は組立式であり、溶接技術はあまり使わずにネジまたはボルトで締結したものであるため、あまり重量物を取付けられないという問題があった。   However, since the gas insulated switchgear control panel 50 is an assembly type and is fastened with screws or bolts without much use of welding technology, there is a problem that heavy objects cannot be attached so much.

一方、筐体１は板金筐体であり、溶接作業を多用しているため、作業者の技能により筐体の歪や溶接不良等の品質にばらつきが多くなるという問題もあった。   On the other hand, since the case 1 is a sheet metal case and uses a lot of welding work, there is a problem that variations in quality such as distortion of the case and poor welding due to the skill of the operator increase.

また、これまで配線・組立作業は制御盤筐体内に作業員が入り行っていたが、図７のように制御盤の幅Ｘが９００ｍｍと狭い場合は作業員一人が全工程の配線・組付け作業することになり、作業工数が多く掛かっていた。   Previously, wiring and assembly work had been performed by workers in the control cabinet. However, if the control panel width X is as narrow as 900 mm as shown in FIG. It was a work and it took a lot of work.

さらに、制御盤の現地据付け時に変電機器から制御盤へ外線ケーブルの繋ぎ込み作業を行う場合、図１０に示す正面奥側の端子台３４へ接続するが、図１１のように、扉の開閉方向が同じ場合、両扉を開けた時の開口部が狭くなり、ガス絶縁開閉機器本体と制御盤間の信号のやり取りを行う外部ケーブルの接続作業性が悪くなるという不都合もあった。   Furthermore, when connecting the external cable from the substation to the control panel when the control panel is installed on the site, it is connected to the terminal block 34 on the back side as shown in FIG. 10, but the door opening / closing direction as shown in FIG. In the case where the two doors are the same, the opening when both doors are opened becomes narrow, and there is a disadvantage that the workability of connecting an external cable for exchanging signals between the gas insulated switchgear main body and the control panel is deteriorated.

一方、前述したように変電機器の定格（１４５ｋＶ、２４５ｋＶ、４２０ｋＶ用ガス絶縁開閉器など）が変わると、制御回路仕様や取付ける部品も異なり、また接続される端子台本数が変わるため、制御盤幅を統一できず、制御盤サイズを標準化できない原因になっていた。   On the other hand, as described above, if the rating of substation equipment (145 kV, 245 kV, 420 kV gas insulated switch, etc.) changes, the control circuit specifications and parts to be installed will also change, and the number of connected terminal blocks will change. Cannot be standardized, and the control panel size cannot be standardized.

そこで、本発明の実施形態は、重量物を取付可能で、配線・組付け作業時間、および現地作業時間等を短縮でき、また容易に大きさの異なる制御盤を構成できる作業性が良好な制御盤用組立式筐体及びその組立方法を提供することを目的とする。   Therefore, the embodiment of the present invention can attach a heavy object, can reduce wiring / assembling work time, on-site work time, etc., and can easily configure a control panel having a different size. It is an object of the present invention to provide an assembly type casing for a panel and an assembly method thereof.

（制御盤用組立式筐体１０の全体構成）
図１乃至図３は、本発明の一実施の形態に係る制御盤用組立式筐体を示すものである。 (Overall configuration of control panel assembly-type housing 10)
1 to 3 show a control panel assembly type housing according to an embodiment of the present invention.

この制御盤用組立式筐体１０は、筐体幅寸法Ｘを９００ｍｍ、高さＹを２２００ｍｍ、奥行きＺを８００ｍｍとした直方体の形状をなしており、その直方体の各辺がフレームで構成されている。この制御盤用組立式筐体１０の内部には、故障表示器２７、メータ２８、ベイ・コントロール・ユニット２９、機器操作スイッチ３０、切換スイッチ３３、断路器／接地装置制御継電器３６等が取付けられている。   The control panel assembly type housing 10 has a rectangular parallelepiped shape with a housing width dimension X of 900 mm, a height Y of 2200 mm, and a depth Z of 800 mm, and each side of the rectangular parallelepiped is constituted by a frame.

また、図４に示すように、直方体をなす６面のうちの正面側、頂面側、底面側に、それぞれ矩形状の補強フレーム１１、屋根フレーム１２、底面フレーム１３が配置される。さらに、屋根フレーム１２及び底面フレーム１３の４隅は４本の前面Ａ柱１４、前面Ｂ柱１５、背面Ａ柱１６、背面Ｂ柱１７で連結されている。   Moreover, as shown in FIG. 4, the rectangular-shaped reinforcement frame 11, the roof frame 12, and the bottom frame 13 are arrange | positioned at the front side, the top surface side, and the bottom face side among six surfaces which make a rectangular parallelepiped, respectively. Further, the four corners of the roof frame 12 and the bottom frame 13 are connected by four front A columns 14, a front B column 15, a back A column 16, and a back B column 17.

また、補強フレーム１１は鉄製であり、この補強フレーム１１の右側柱１１ａを軸として、重量物である内扉３が開閉可能に取り付けられる。   Further, the reinforcing frame 11 is made of iron, and the inner door 3 that is a heavy object is attached to be openable and closable with the right column 11a of the reinforcing frame 11 as an axis.

さらに、図４中左面内側にはＡパネル２１が、背面内側にはＢパネル２２が、右面内側にはＣパネル２３が着脱可能に取り付けられる。   Further, in FIG. 4, an A panel 21 is detachably attached to the left inner surface, a B panel 22 is attached to the rear inner surface, and a C panel 23 is attached to the right inner surface.

また、屋根フレーム１２には、図５に示すように、フレームの４隅に補助ガイド５が、底面フレーム１３には、図６に示すように、フレームの４隅に補助ガイド６が溶接で突出して取り付けられ、４本の前面Ａ柱１４、前面Ｂ柱１５、背面Ａ柱１６、背面Ｂ柱１７を連結する際の補助とされる。   Further, as shown in FIG. 5, the auxiliary guide 5 protrudes from the four corners of the frame to the roof frame 12, and the auxiliary guide 6 protrudes from the four corners of the bottom frame 13 by welding as shown in FIG. The four front A pillars 14, the front B pillar 15, the rear A pillar 16, and the rear B pillar 17 are connected to each other.

底面フレーム１３は、アンカーで固定されたコンクリート製のベース７上に固定される。   The bottom frame 13 is fixed on a concrete base 7 fixed with anchors.

また、補強フレーム１１の左側柱１１ｂを軸として、外扉２が開閉可能に取り付けられる。   Moreover, the outer door 2 is attached so that opening and closing is possible centering | focusing on the left pillar 11b of the reinforcement frame 11. As shown in FIG.

さらに、図４中左面外側にはＡパネル用板２４が、背面外側にはＢパネル用板２５が、右面外側にはＣパネル用板２６が取り付けられている。   Further, in FIG. 4, an A panel plate 24 is attached to the left outer side, a B panel plate 25 is attached to the rear outer side, and a C panel plate 26 is attached to the right outer side.

以下、この制御盤用組立式筐体１０の組立方法について図４を参照して説明する。   Hereinafter, a method for assembling the control panel assembly-type casing 10 will be described with reference to FIG.

（組立方法）
先ず、金属板を断面コ型状に折り曲げて溶接により矩形の枠状に形成して強度を持たせた補強フレーム１１を用意し、外扉２と配線・組付け作業を実施した内扉３を開閉方向が逆となるように取り付ける。 (Assembly method)
First, a reinforcing frame 11 is prepared by bending a metal plate into a U-shaped cross section and forming a rectangular frame shape by welding to give strength, and the outer door 2 and the inner door 3 on which wiring and assembling operations are performed. Install so that the opening and closing direction is reversed.

次に、この補強フレーム１１と前面Ａ柱１４、前面Ｂ柱１５、背面Ａ柱１６、背面Ｂ柱１７に配線・組付け作業を実施したＡパネル２１とＣパネル２３、更には、背面側のＢパネル２２を取付ける。   Next, the A panel 21 and the C panel 23 in which the reinforcing frame 11, the front A column 14, the front B column 15, the back A column 16, the back B column 17 are wired and assembled, and the rear side Install the B panel 22.

最後に、屋根フレーム１２と底面フレーム１３、さらにはベース７を取付け、筐体構造を構成する。   Finally, the roof frame 12, the bottom frame 13, and the base 7 are attached to form a housing structure.

また、筐体幅寸法Ｘを例えば９００ｍｍとし、異なる要求仕様がある場合（例えば、４２０ｋＶ用）は２面の筐体を連結させ、１８００ｍｍ幅の制御盤とする。   Further, when the housing width dimension X is, for example, 900 mm and there are different required specifications (for example, for 420 kV), the two-side housings are connected to form a control panel having a width of 1800 mm.

（制御盤用組立式筐体１０の特徴）
このように構成された制御盤用組立式筐体１０では、コ字型に折り曲げてフレームに強度を持たせた補強フレーム１１を採用しているため、重量物を取付け可能な制御盤を構成できる。 (Characteristics of control panel assembly type housing 10)
In the control panel assembly-type casing 10 configured as described above, the reinforcing frame 11 that is bent into a U-shape and has a strong frame is employed, so that a control panel to which a heavy object can be attached can be configured. .

さらに、図５の屋根フレーム１２と、図６の底面フレーム１３は、溶接でそれぞれ補助ガイド５，６が取り付けられているので、この補助ガイド５，６と前面Ａ柱１４と前面Ｂ柱１５、背面Ａ柱１６と背面Ｂ柱１７をボルトで締結し、さらに補強フレーム１１と連結することにより筐体の歪み等の発生を防止することができる。   Further, since the auxiliary guides 5 and 6 are attached to the roof frame 12 of FIG. 5 and the bottom frame 13 of FIG. 6 by welding, respectively, the auxiliary guides 5 and 6, the front A column 14 and the front B column 15, The back A column 16 and the back B column 17 are fastened with bolts and further connected to the reinforcing frame 11 to prevent the housing from being distorted.

また、Ａパネル２１、Ｂパネル２２、Ｃパネル２３はそれぞれ独立しているので、従来のように狭い筐体内で配線・組付け作業を行うのではなく外でそれぞれの作業を同時に行うことができる。特に、Ａ，Ｂ，Ｃ３面のパネル間の接続は、パネル単位で配線・組付け作業を完了させ、補強フレーム１１に組み付ける直前に行うことで効率的な作業を行うことが可能となる。   In addition, since the A panel 21, the B panel 22, and the C panel 23 are independent from each other, it is possible to perform the respective operations at the same time instead of performing the wiring and assembling operations in the narrow casing as in the conventional case. . In particular, the connections between the A, B, and C3 panels can be efficiently performed by completing the wiring and assembling work for each panel and immediately before assembling the reinforcing frame 11.

また、制御盤の現地据付け時に変電機器から制御盤へ外線ケーブルの繋ぎ込み作業を行う場合、例えば、図１０に示す正面奥側の端子台３４へ接続するが、図１１のように扉の開閉方向が同じ場合、開口部が狭くなり作業性が悪くなる。これに対して、図４に示す制御盤側補強フレーム１１に取り付けられた外扉２と内扉３はそれぞれ開閉方向が異なることから(図３参照)、両扉を開いた時の開口部寸法を大きく取ることができ、外線ケーブルの繋ぎ込み作業時の作業スペースを確保することができる。   In addition, when connecting the external cable from the substation to the control panel when the control panel is installed on the site, for example, it is connected to the terminal block 34 on the back side of the front as shown in FIG. If the directions are the same, the opening becomes narrow and the workability deteriorates. On the other hand, since the opening and closing directions of the outer door 2 and the inner door 3 attached to the control panel side reinforcing frame 11 shown in FIG. 4 are different from each other (see FIG. 3), the opening dimensions when both doors are opened. Therefore, it is possible to secure a work space for connecting the external cable.

さらに、異なる要求仕様のある場合は、例えば、９００ｍｍ幅の筐体を連結させ、１８００ｍｍ幅の制御盤にすることにより、要求仕様を満足させることが可能となる。これにより、フレーム類を共通化させることが可能となり、筐体の設計時間削減やフレーム類のストック化を図ることにより制御盤用筐体のコストダウンを実現できる。また、組立式筐体のためユニットを連結することにより大きさの異なる制御盤を構成することが出来る。   Further, when there are different required specifications, for example, the required specifications can be satisfied by connecting a chassis with a width of 900 mm to form a control panel with a width of 1800 mm. As a result, the frames can be shared, and the cost of the control panel casing can be reduced by reducing the housing design time and stocking the frames. Further, since the units are assembled, the control panels having different sizes can be configured.

（本実施形態の効果）
以上のことから、強度を有する補強フレーム１１に内扉等の重量物を取付可能な制御盤用組立式筐体１０を提供することができる。 (Effect of this embodiment)
From the above, it is possible to provide the control panel assembling-type casing 10 capable of attaching a heavy object such as an inner door to the reinforcing frame 11 having strength.

また、配線・組付け作業時間、および現地作業時間を短縮することも出来る。   In addition, wiring / assembling work time and on-site work time can be shortened.

さらに、ユニットの組み合わせにより大きさの異なる制御盤を構成することが可能な制御盤を提供できる。   Furthermore, it is possible to provide a control panel capable of configuring control panels having different sizes depending on the combination of units.
