Abstract
The utility model discloses a load switch cabinet of a solid insulating annular network. The load switch cabinet comprises a solid insulating inlet end three-phase busbar installed in a cabinet body, a solid insulating isolating switch connected with the solid insulating inlet end three-phase busbar, a solid insulating cable boot connection member connected with the solid insulating isolating switch, solid insulating layers and semi-conducting material layers, wherein the solid insulating layers and the semi-conducting material layers are wrapped outside the load switch cabinet except for connection ports. The solid insulating inlet end three-phase busbar is arranged under the solid insulating isolating switch, the solid insulating cable boot connection member is arranged above the solid insulating isolating switch, and a semi-circular pressure-equalizing casing is arranged in the solid insulating isolating switch. The parts are all connected through inserting of plugs and jacks, and the semi-conducting materials layers arranged on the surfaces of the parts are connected with the cabinet body in conducting mode through bolts and inserts. Compared with the prior art, the load switch cabinet solves the problem that the existing load switch cabinet of the solid insulating annular network is large in size, inconvenient to maintain and the like.
