Problems solved by technology

[0005] During the follow-up R&D and trial production process, the applicant found that two semi-circular metal retaining rings are welded and fixed to the metal mounting seat, so as to ensure that the metal mounting seat is firmly fixed on the ceramic outer wall. This structure is feasible and can meet the requirements of the national Relevant standards, but the operation process of its processing and installation is relatively cumbersome, and it is necessary to use a special special fixture to clamp the metal retaining ring and the metal mounting seat, so that it can be welded smoothly

Description

technical field [0001] The invention relates to the technical field of ceramic insulator structure design, in particular to a ceramic insulator and a high-voltage power capacitor insulator device made of the ceramic insulator. 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] Traditional ceramic insulators need to weld metal wiring components and mounting components to the body of the ceramic insulator. Due to the particularity of ceramics, special solder with silver alloy as the main component needs to be used. This solder is very expensive. 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 cost of this kind of insulator; in addition, in...
