Problems solved by technology

[0004] The traditional gas insulated switchgear adopts the above structure. When the busbar is connected, the operator must climb on the top wall of the container above the switchgear, so it is dangerous to work at a high place, and because the upper part of the switchgear must withstand the busbar connection operator. weight, therefore need to strengthen the container and increase the cost
[0005] In addition, since the busbar sleeve and the entry-side terminal of the circuit breaker with grounding switch are installed on different surfaces, the position error of the mutual installation holes is large. , the connection terminals must be flexible, which increases the cost

Embodiment Construction

[0010] Such as figure 1 As shown, a container 2 is set on a stand 1 made of a thin metal plate. The front of the container 2 (left side in the drawing) is in the shape of a cutout. The container 2 has: a container body 2b having an opening 2a formed on the container wall at the front of the container; insulating gas. The mounting plate 3 is a single flat plate shape in substantially the same plane. On the back side of the mounting plate 3, a hollow insulating support made of a fixed insulator is installed, that is, a supporting insulating cylinder 4. One side of the supporting insulating cylinder 4 is connected to the There is a gap between the main circuit parts of the vacuum interrupter 5, and the vacuum switch tube (VST) 6, which is the interrupter, is accommodated inside the supporting insulating cylinder 4, and the movable shaft 7 of the vacuum switch tube 6 is connected to the grounding switch. The breaker blade supports the main circuit part of the vacuum interrupter...

Abstract

A circuit breaker, a disconnecting device with a ground switch and a bushing for feed line are all mounted on and supported by a single, planar mounting plate in a tank filled with an insulation gas. The disconnecting device with a ground switch has a ground side terminal which is disposed at a position below the bushing for feed line and is mounted on the mounting plate. The circuit breaker and the disconnecting device with a ground switch are supported by an insulated supporting cylinder which is supported by the mounting plate.

Description

technical field [0001] The present invention relates to a gas insulated switchgear, and more particularly to a gas insulated switchgear provided with a container having a removable mounting plate sealing the front of the container body. Background technique [0002] In traditional gas insulated switchgear, main circuit components such as breakers and circuit breakers with grounding switches are housed in containers filled with insulating gas, and sleeves for connecting busbars are penetrated and installed in these main circuits. In the through hole on the top wall of the container above the component. In addition, the circuit breaker is installed on the front wall of the container, and the circuit breaker with the grounding switch is installed on the bottom wall of the container (for example, refer to Japanese Patent Laid-Open No. 2001-352623, figure 1 and figure 2 ). [0003] There is also a conventional gas insulated switchgear in which the container is divided into tw...
