Problems solved by technology

[0002] The traditional isolating and grounding switch combination structure (abbreviation: disconnecting combination) usually requires two operating mechanisms to complete the opening and closing of the disconnecting combination, and at the same time, the interlock between the disconnecting switch and the grounding switch is required in the secondary control; , the overall structure is relatively complex, bulky and inconvenient to maintain
The new type of combined electrical appliances adopts modularization, the overall structure is simple, and it is convenient to use and operate, but its cost is high, and some existing equipment cannot be well utilized.

Abstract

The present invention discloses a 126KV compound composite apparatus which aims to solve problems like complex structure and great volume in prior art. The invention comprises an air chamber by isolating switch housing, wherein a dynamic contact, a isolation switch static contact and a ground switch static contact are set in the air chamber; the ground switch static contact is set on one side of the air chamber and forms a phase angle of 90 DEG with the isolation switch; the dynamic contact is set between the isolation switch static contact in rotatable way and the ground switch static contact through a controlled shaft. In the above structure, the isolation switch and the ground switch adopt three working positions composite structure, opening and closing of the isolation switch and the ground switch can be done with only one operating mechanism without interlock between the isolation switch and the ground switch, hence cost is reduced and space is saved, and the rapid ground switch and the isolation switch share one air chamber. Compared with traditional structure appearance, the invention is provided with small volume, good-look and compact appearance.

Description

technical field [0001] The invention relates to an SF6 gas-insulated fully enclosed 126KV composite combined electric appliance. Background technique [0002] The traditional isolating and grounding switch combination structure (abbreviation: disconnecting combination) usually requires two operating mechanisms to complete the opening and closing of the disconnecting combination, and at the same time, the interlock between the disconnecting switch and the grounding switch is required in the secondary control; , the overall structure is relatively complex, bulky, and inconvenient to maintain. The new type of combined electric appliance adopts modularization, the overall structure is simple, and it is convenient to use and operate, but its cost is high, and some existing equipment cannot be well utilized. Contents of the invention [0003] In order to overcome the above-mentioned defects, the object of the present invention is to provide a 126KV composite combined electrical...
