Low-temperature insulation high-temperature superconducting cable high-voltage terminal

Abstract

A disclosed low-temperature insulation high-temperature superconducting cable high-voltage terminal comprises an insulation pipeline, a mounting sleeve is fixedly connected to the top of the insulation pipeline, and a protection mechanism is arranged on the outer side of the mounting sleeve. According to the low-temperature insulation high-temperature superconducting cable high-voltage terminal, the terminal can be protected through an outer cover after wiring of the terminal, accidental touch by others can be avoided, the top of the outer cover can be blocked through the arrangement of a rubber conical disc and a notch, water flow is prevented from entering the outer cover, the protection effect on the terminal is further improved, water seepage at the joint of the outer wall of a heat shrink tube and the outer wall of an insulating pipeline can be avoided, the heat shrink tube and a single-hole umbrella group can be disassembled and assembled conveniently, the use convenience is improved, a taper sleeve can rotate up and down to drive an ejector rod to slide centripetally or centrifugally at the same time through arrangement of the ejector rod and threaded connection of the taper sleeve and the insulating pipeline, and therefore, the cable joint can be limited and fixed, and the connection stability is improved.

Description
