Abstract

An isolating and grounding switch mechanism (1) and a gas-insulated metal-enclosed switchgear. The isolating and grounding switch mechanism (1) comprises a housing (19), an isolating switch (12), and a grounding switch (11). The isolating switch (12) comprises an isolating switch moving contact (124) and an isolating switch stationary contact (123) that are provided in parallel along an axial direction. The grounding switch (11) comprises a grounding switch moving contact (112) and a grounding switch stationary contact (113). The interior of the housing (19) is provided with a transformer connection terminal (145), an external connection terminal for connection to a main loop access conductive structure, and a guide contact base (14) and a connection contact base (15) horizontally provided in parallel along the axial direction. The transformer connection terminal (145) is provided on the guide contact base (14). The isolating switch stationary contact (123) is provided at a position of the connection contact base (15) facing the guide contact base (14). The external connection terminal is provided at a position of the connection contact base (15) that allows access of the main loop access conductive structure along the axial direction. The isolating switch moving contact (124) is axially guided to pass through the guide contact base (14), and has a switching-on station that is in contact fit with the connection contact base (15).

Description

technical field [0001] The invention relates to the field of high-voltage switchgear, in particular to an isolation grounding switch mechanism and a gas-insulated metal-enclosed switchgear. 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 electrica...
