A ceramic insulator device for high voltage capacitor

Abstract

The invention discloses a ceramic insulator device for high voltage capacitor comprising a ceramic insulator body, wiring assembly and mounting assembly; the insulator body is provided with an annular positioning boss at outer wall of bottom part; the mounting assembly comprises metal mounting base, upper seal ring, lower seal ring and two semi-circle metal baffle ring; the metal mounting base is basically tubular provided with a inward protruding baffle ring at lower part; the metal mounting base is sleeved onto outer wall of lower part of insulator body; the baffle ring is positioned at lower part of annular positioning boss; a lower seal ring is sleeved onto outer wall of insulator body and positioned between lower surface of annular positioning boss and baffle ring; upper seal ring is sleeved onto outer wall of lower part of the insulator body and positioned at upper surface of annular positioning boss; two metal baffle rings are provided at upper surface of upper seal ring and weldingly fixed with metal mounting base. The invention has merits of low cost, convenient processing and production.

Description

technical field [0001] The present invention relates to high-voltage capacitors, in particular to a ceramic insulator device for high-voltage capacitors. Background technique [0002] The ceramic insulators of high-voltage capacitors currently on the market use silver to weld the mounting part and the ceramic body together to make it firmly fixed on the ceramic body. This product has high cost, cumbersome steps, and long processing time. [0003] Figure 1 to Figure 4 shows a conventional ceramic insulator arrangement used in high voltage capacitors, where, figure 1 It is a schematic diagram of the three-dimensional structure of a traditional ceramic insulator device used in high-voltage capacitors; figure 2 yes figure 1 A half-sectional view of the conventional insulator device shown; image 3 yes figure 2 The enlarged schematic diagram of the local structure at A; Figure 4 yes figure 2 The enlarged schematic diagram of the local structure in B.

AI Technical Summary

Problems solved by technology

Due to the particularity of ceramics, the silver alloy used is a special special solder, which is very expensive, and in order to ensure the firmness of the combination of the two, a relatively thick solder layer is required, and more materials are used, resulting in high costs for this type of insulator. In addition, in order to formulate this silver alloy into a viscous fluid state that is easy to smear, it is necessary to use acidic chemicals with a relatively high degree of pollution, which is not conducive to protecting the environment
