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 combined switchgear. Background technique [0002] In recent years, the miniaturization of switchgear is a research hotspot in the industry. At present, most domestic 10kV switch cabinets are connected by fixed modules through busbars, and the air distance is strictly implemented in accordance with 125mm. Therefore, the cabinet is large in size and the use environment is also restricted; and most miniaturized switch cabinets use gas-filled cabinet solutions to meet the reduction of phases. And the relative insulation distance. Since the SF6 gas charged is a greenhouse gas, it is not a promotional product. In order to make up for the shortcomings of the greenhouse effect and easy air leakage of the SF6 inflatable cabinet, as well as the shortcomings of the large area of ​​the air-insulated switchgear. At present, it is necessary to develop a new type of switchgear, which can meet the requirements of miniaturizat...
