Abstract

The invention relates to the field of high-voltage switch equipment, in particular to a disconnecting grounding switch mechanism, switch equipment and a guide contact base of the disconnecting grounding switch mechanism. The guide contact base comprises a base body and a disconnecting switch moving contact base arranged on the base body, a guide hole used fro being horizontally formed in the disconnecting grounding switch mechanism is formed in the base, an opening in one end of the guide hole is used for facing the connecting-in direction of a main circuit connecting-in conducting structure, an opening in the other end is used for facing the inserting direction of a disconnecting switch moving contact, and a mutual inductor connecting terminal is further arranged on the base body. The problem that an existing guide contact is prone to causing large occupied space and inconvenient assembly and disassembly of the disconnecting grounding switch mechanism is solved.

Description

technical field [0001] The invention relates to the field of high-voltage switchgear, in particular to an isolation grounding switch mechanism, a switchgear and a guiding contact seat thereof. Background technique [0002] At present, the current transformer connection position and the busbar connection position of the isolation grounding switch mechanism of the gas-insulated metal-enclosed switchgear with 3 / 2 connection (hereinafter referred to as GIS) are generally arranged on the left and right, such as figure 1 As shown, the isolating grounding switch mechanism 101 can only be installed in a straight line with the current transformer 102, the bus bar 104, and the circuit breaker 103 during use, which results in a long 3 / 2 wiring interval, resulting in the current 3 / 2 Wiring the problem of large GIS footprint. In order to solve the problem that GIS occupies a large area, the existing technology has used L-shaped main conductive loops to reduce the footprint of GIS electr...
