Design Of High-Voltage Electrical Connector

The program chose in this paper is preceded from the military electronic components research project agreement that gives the 40th Research Institute of Electron Tech Group Organization of Chinese by Information Industry Department Military Office.This paper outlines the development present situation in home and the world about the high voltage electrical connector. Which is general to have stated professional technical knowledge and domestic and international basic theory of the high voltage electrical connector. For the design principle, which includes mainly the air breakdown principle, air space insulation, expand process of the air breakdown in the even electric field and the ways of single and many layer dielectrics' calculation of electric field in high voltage electric insulation technology. Analyses and calculates the site strong change condition when connector transmits high voltage signal. Have described the design course of the high voltage electrical connector that is design method and production technology, focal point for how to take effective measurement so as to raise the ability of withstanding voltage and pore breakdown and avoid or reduce the aspects such as partial discharge analyse. In the aspect of structural design have adopted to insert join interface place soft, hard insulating material," cone " with the tight coordination extruding " cone hole" way, so as reach to eliminate interface place the method of air crack purpose; Each contact joint surface the cylindrical structure of the transition of circular arc so make electric field as far as possible even. In the aspect of production processing to reduce the possibility that corona produces with eliminate any route for land, through using some special productions technology and in the material owned between carry out good combination or glue sealed method, the purpose of gas reaches to exclude each node place, we can design or make the satisfactory the high voltage connectors without the air gap.For the type of high voltage electrical connector, we can't collect or discover the similar product in home, also without corresponding country army standard. Therefore we have drafted corresponding industrially army standard, and established corresponding test system, so for the product, can carry out test verification at the right moment properly.
