Do. The opening and the connecting portion 52 may be not the side portion of the box body 511a, but may be the upper portion, the lower portion, and the back side portion.
 図4は、図3において小扉512aを開けた時の状態を示す図である。小扉512aを開けても、制御室50aとの間に箱体511aが残り、制御室50aが直接外部に晒されることはなく、また制御機器510を小扉512a側に引き出すことができ、メンテナンスが容易になる。メンテナンス等の時には、筺体10の扉9を開く必要がなく、制御機器ごとに対応する小扉を開ければよい。 FIG. 4 is a diagram showing a state when the small door 512a is opened in FIG. Even if the small door 512a is opened, the box body 511a remains between the small door 512a and the control room 50a is not directly exposed to the outside, and the control device 510 can be pulled out to the small door 512a side for maintenance. Becomes easier. At the time of maintenance or the like, it is not necessary to open the door 9 of the housing 10, and it is sufficient to open the corresponding small door for each control device.
 図5は、制御機器510を小扉512aに取り付けず、箱体511aに設置した例を示す図である。このように制御機器を510は小扉512aに取り付けなくても、小扉512aを開けばメンテナンス時の作業性はよい。 FIG. 5 is a diagram showing an example in which the control device 510 is not attached to the small door 512a but is installed in the box body 511a. As described above, even if the control device 510 is not attached to the small door 512a, the workability at the time of maintenance is good if the small door 512a is opened.
 以上のように実施の形態1によれば、制御機器を収納する制御機器室を制御室内に設けることで、内部アーク発生時に高温ガスが制御室に侵入しても、あるいは急激な圧力上昇に対しても、制御機器室の箱体により高温ガスの侵入及び圧力上昇の影響を抑制し、各制御機器の損傷を抑制することができる。また、制御線の接続も箱体の隙間を塞ぐように接続部を設けて行うので、接続部での高温ガスの侵入は抑制される。
 さらに、制御機器室を前方の筺体の扉に設けているので、遮断器室からの距離も確保することが可能となる。
 また、制御機器室に小扉を設けているので、制御機器のメンテナンス、点検等の時には個別の小扉を開閉することで対応でき、メンテナンス性も向上する。
As described above, according to the first embodiment, by providing the control equipment room for accommodating the control equipment in the control room, even if a high temperature gas invades the control room when an internal arc is generated, or when the pressure rises sharply However, the box body in the control equipment room can suppress the influence of high temperature gas intrusion and pressure rise, and can suppress damage to each control equipment. Further, since the control line is also connected by providing the connecting portion so as to close the gap of the box body, the intrusion of high temperature gas at the connecting portion is suppressed.
Further, since the control equipment room is provided on the door of the front housing, it is possible to secure a distance from the circuit breaker room.
In addition, since a small door is provided in the control equipment room, maintenance and inspection of the control equipment can be handled by opening and closing individual small doors, and maintainability is improved.
 なお、箱体と小扉を一体化して制御機器室を構成すると密閉性を容易に確保することができるという利点があるが、密閉性を確保できれば、一体化する必要はない。箱体はスイッチギヤの運転中は制御機器のカバーとして取り付け、メンテナンスの際には取り外しができるようにしてもよい。 Note that if the box body and the small door are integrated to form the control equipment room, there is an advantage that the airtightness can be easily secured, but if the airtightness can be ensured, it is not necessary to integrate them. The box body may be attached as a cover of the control device during the operation of the switch gear so that it can be removed during maintenance.
実施の形態2.
 以下、実施の形態2に係るスイッチギヤについて図を用いて説明する。
 実施の形態1では、制御機器室を箱体と小扉とを用いて構成したが、実施の形態2では筺体10の扉9に制御機器を直接取り付けて、箱体を制御機器のカバーとして覆うように制御機器室を構成した。
Embodiment 2.
Hereinafter, the switch gear according to the second embodiment will be described with reference to the drawings.
In the first embodiment, the control device room is configured by using the box body and the small door, but in the second embodiment, the control device is directly attached to the door 9 of the housing 10 to cover the box body as a cover of the control device. The control equipment room was configured as described above.
 図6は、スイッチギヤ1の一部横断面図で、制御機器室510aを含む制御室50aの一部構成を示したものである。制御機器510は筺体10の扉9に取り付けられ、箱体511aが制御機器510を覆うようにかつその内部に制御機器510を収納している。このように、扉9の一部と箱体511aとで、制御機器室510aを構成する。箱体には制御線51を引き出すために開口部が設けられ、その隙間を塞ぐように接続部52が設けられている。接続部52の構成等は実施の形態1と同様である。 FIG. 6 is a partial cross-sectional view of the switch gear 1 and shows a partial configuration of the control chamber 50a including the control equipment chamber 510a. The control device 510 is attached to the door 9 of the housing 10, and the control device 510 is housed in the box body 511a so as to cover the control device 510. In this way, a part of the door 9 and the box body 511a form a control equipment room 510a. The box body is provided with an opening for pulling out the control line 51, and a connecting portion 52 is provided so as to close the gap. The configuration of the connecting portion 52 and the like are the same as those in the first embodiment.

 また、制御機器室の箱体を取り外し可能に筺体の扉に設けているので、制御機器のメンテナンス、点検等の時には個別に箱体を取り外せばよく、制御機器の損傷を抑制とメンテナンス性の両立が図れる。
 また、小扉を設けないため、簡便に制御機器室を構成することが可能となる。
As described above, according to the second embodiment, the same effect as that of the first embodiment is obtained. That is, by providing a control equipment room for accommodating the control equipment in the control room, even if a high temperature gas invades the control room when an internal arc is generated, or even if a sudden pressure rise occurs, the box body of the control equipment room It is possible to suppress the influence of high temperature gas intrusion and pressure rise, and to suppress damage to each control device. Further, since the control line is also connected by providing the connecting portion so as to close the gap of the box body, the intrusion of high temperature gas at the connecting portion is suppressed. Further, since the control equipment room is provided on the door of the front housing, it is possible to secure a distance from the circuit breaker room.
In addition, since the box body of the control equipment room is detachably provided on the door of the housing, the box body can be removed individually for maintenance and inspection of the control equipment, and damage to the control equipment can be suppressed and maintainability can be achieved at the same time. Can be planned.
Further, since the small door is not provided, the control equipment room can be easily configured.
