Abstract

The invention relates to a solid insulation combination switchgear. The solid insulation combination switchgear comprises a main switch assembly and a fuse assembly electrically connected with the main switch assembly. The main switch assembly comprises a main switch insulation base body for conducting solid sealing on an electrical module of the main switch assembly. The fuse assembly comprises a fuse insulation base body for conducting solid sealing on an electrical module of the fuse assembly. The outer surface of the main switch insulation base body and the outer surface of the fuse insulation base body are each coated with a ground layer. According to the solid insulation combination switchgear, a switch cabinet is made to be miniaturized, and safety and the connection reliability are high.

Description

technical field [0001] The invention relates to a solid insulation combination switchgear. Background technique [0002] In recent years, the miniaturization of switchgear is a research hotspot in the industry. At present, most domestic 10kV switchgears are made of fixed modules connected by busbars, and the air distance is strictly implemented according to 125mm. Therefore, the cabinets are large in size and the use environment is also limited; while most of the miniaturized switchgears use the air-filled cabinet solution to meet the reduction of phases. And the relative insulation distance. Since the charged SF6 gas is a greenhouse gas, it is not a promotional product. In order to make up for the shortcomings of SF6 inflatable cabinets such as greenhouse effect and easy air leakage, as well as the shortcomings of large footprint of air-insulated switchgear. At present, it is necessary to develop a new type of switchgear, which can not only meet the requirements of minia...
