The invention discloses a solid insulating looped network load switch cabinet. The solid insulating looped network load switch cabinet comprises a solid insulating inlet end three-phase bus, a solid insulating disconnecting switch, a solid insulating cable shoe connecting part, solid insulating layers, semi-conducting material layers and the like, wherein the solid insulating inlet end three-phase bus is installed inside a cabinet body, the solid insulating disconnecting switch is connected with the solid insulating inlet end three-phase bus, the solid insulating cable shoe connecting part is connected with the solid insulating disconnecting switch, and outer portions of the cabinet, except connecting ports, are covered with solid insulating layers, semi-conducting material layers and the like. The solid insulating inlet end three-phase bus is arranged below the solid insulating disconnecting switch, the solid insulating cable shoe connecting part is arranged above the solid insulating disconnecting switch, a half-round grading shield is arranged inside the solid insulating disconnecting switch, the solid insulating inlet end three-phase bus, the solid insulating disconnecting switch and the solid insulating cable shoe connecting part are connected in an inserting mode through plugs and jacks, and semi-conducting material layers on surfaces of the solid insulating inlet end three-phase bus, the solid insulating disconnecting switch and the solid insulating cable shoe connecting part are in conductive connection with the cabinet body through bolts and inserts. Compared with the prior art, the solid insulating looped network load switch cabinet has the advantages that being capable of solving the problems that existing solid insulating looped network load switch cabinets are large in volume, inconvenient to maintain and the like.
Description
technical field [0001] The invention relates to the technical field of high-voltage power equipment manufacturing, in particular to a load switch cabinet in which all primary components are insulated by solids. Background technique [0002] The existing solid insulated ring network load switchgear is equipped with a three-phase isolating switch and a circuit breaker for connecting and breaking the incoming three-phase busbar and terminal three-phase busbar in the primary circuit of the cabinet. This solid insulated ring network series Most of the isolating switch in the load switch cabinet and the connecting end of the primary line use air or sulfur hexafluoride gas as the insulating medium. Sulfur gas insulation. Since air or sulfur hexafluoride gas is used for isolation and insulation, sufficient isolation distances are required between phases and relative grounds, so the overall size of the cabinet will be larger.
