Abstract

The invention discloses a fixing sealing pole for electric power, which comprises an epoxy resin shell, an upper outlet base, a lower outlet base, a fixing insert and an outer convex ring. The epoxy resin shell is connected with the upper outlet base and the lower outlet base, the upper outlet base is located at the top of the epoxy resin shell, and the lower outlet base is located at one side ofthe epoxy resin shell. The epoxy resin shell is provided with a vacuum arc extinguishing chamber, a conductive chamber and an insulating tie rod chamber, wherein the insulating tie rod chamber is located at the lower end of the epoxy resin shell, and the insulating tie rod chamber is sequentially provided with the conductive chamber and the vacuum arc extinguishing chamber; the upper outlet base is connected with that top of the vacuum interrupter; the lower outlet base is connected to one side of that insulate tie rod chamber; the inside of the epoxy resin shell at the bottom of the insulating rod chamber is provided with the fixing insert; the outer side of the epoxy resin housing outside the insulating tie rod is provided with the outer convex ring. The invention has the characteristicsof strong thermal stability and strong bending and tensile resistance.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a solid-sealed pole for electric power with strong thermal stability and strong resistance to bending and stretching. Background technique [0002] At present, vacuum circuit breakers have been recognized by the market for their stable performance and have been widely used. The embedded pole is to embed the conductive parts related to the vacuum interrupter and the circuit breaker into the solid insulating material to form the pole, so that the embedded pole becomes an integral part. As a single pole of vacuum circuit breakers, the demand for solid-sealed poles is very large. The solid-sealed pole is made of epoxy resin or other thermoplastic materials by casting the upper outlet seat, vacuum interrupter, lower outlet seat and other accessories. Epoxy resins have excellent electrical and mechanical properties, but have very poor thermal conductivity. When the rated ...
