Stress cone component and high-voltage cable connector component

Abstract

Disclosed is a stress cone component of a high-voltage device. The stress cone component comprises a telescopic sleeve, a conduction tube and a telescopic electrode, wherein the telescopic sleeve comprises a first portion and a second portion; the conduction tube is fixed on the inner wall of the first portion of the telescopic sleeve; and the telescopic electrode is attached to the inner wall of the second portion of the telescopic sleeve, the telescopic electrode comprises a first opening and a second opening, the telescopic electrode is electrically connected with an inner side end of the conduction tube at the position of the first opening, and the second opening is constructed into an elastic clamp and is inserted into a high-voltage cable of the second portion of the telescopic sleeve. The invention further provides a high-voltage cable connector component with the stress cone component, and an elasticity stress portion of the high-voltage cable connector component can be applicable to high-voltage cables with different diameters.

Description

technical field [0001] The present invention relates to a high-voltage cable connector, in particular to a stress cone assembly applicable to high-voltage cables with different diameters, and a high-voltage cable connector assembly with the stress cone assembly. Background technique [0002] When connecting high-voltage cables to high-voltage electrical equipment such as generators, motors, transformers, and gas-insulated switches (GIS), high-voltage cable connectors are required to facilitate, reliably and safely connect electrical equipment to high-voltage cables. figure 1 A partial cross-sectional view of a prior art high voltage cable connector 100 is shown. In this high-voltage cable connector 100, a high-voltage electrode 102 electrically connected to a corresponding high-voltage electrode of an electrical device is fixed at the front end of an insulating sleeve 101 made of, for example, epoxy resin material, and a high-voltage electrode 102 is provided at the rear end...

Problems solved by technology

[0004] However, in this high-voltage cable connector assembly 200, since the adapter 207 is provided, the complexity of the entire high-voltage cable connector 200 assembly is increased; since the elastic body 205 has a certain length, there is no fixing and protection device outside it, and the high-voltage The cable 206 is often relatively heavy, which easily causes the elastic body 205 to bend sideways, and even loosens the insulating interface between the elastic body 205 and the adapter 205, which affects the electrical performance of the product; in the case of severe external force, it is easy to cause the elastic body 205 to tear damage, or cause electrical breakdown; the longer elastic body 205 is not protected by a closed mechanical structure, it is difficult to resist the erosion of external acid and alkali substances, which reduces the service life of the elastic body 205, so it is not suitable for outdoor use
