Embodiment Construction

[0009] The invention adopts high-temperature vulcanized silicone rubber as the transition material between the epoxy resin and the ceramic shell of the vacuum interrupter, and evenly sprays the adhesive on the joint surface of the silicon rubber and the ceramic shell of the arc extinguisher, and the joint surface of the silicone rubber and the epoxy resin Material. The process is divided into two parts: first, the arc extinguishing chamber of the high-voltage vacuum circuit breaker's solid-sealed pole is made by the vulcanization process, and then the high-voltage vacuum circuit-breaker's solid-sealed pole is integrally formed by the APG epoxy resin injection process. Silicone rubber is directly molded on the outer surface of the vacuum interrupter by vulcanization technology, which serves as a transition layer between the epoxy resin of the solid-sealed pole and the ceramic shell of the interrupter. Adhesive is evenly sprayed on the bonding surface between the silicone rubber...

Abstract

The utility model relates to a production process for a xerogel of high voltage vacuum circuit breaker, which is characterized in that a high temperature vulcanizing silicone rubber is adopted as a transitional material between epoxy resin and a porcelain housing of the a vacuum interrupter chamber, and adhesive is applied evenly on the connecting planes between the vulcanizing silicone rubber and the porcelain housing of the vacuum arcing chamber and between the vulcanizing silicone rubber and the epoxy resin. The process comprises two parts: first, the arcing chamber of the high voltage vacuum breaker xerogel is made by using vulcanizing process, second, the integration formation of the high voltage circuit breaker xerogel is made by utilizing an APG expoy resin winding injection process. The utility model has advantages of simple process, good insulation and reliable operation and strong acclimation capability of the produced product. The utility model is applicable to the production enterprises of the xerogel vacuum circuit breaker.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a production process of a solid-sealed pole of a high-voltage vacuum circuit breaker. Background technique [0002] AC vacuum circuit breakers are applied to power distribution equipment with a voltage of 6-40.5KV. Because of its high voltage level, the requirements for its insulation degree are relatively strict, otherwise the performance of the circuit breaker will be affected. At present, the vacuum circuit breakers on the market include the VEP type produced by Xiamen Huadian Company, the VD4P type produced by ABB, and the 3AH2-EP type produced by Siemens, such as VS1 and VD4 products, and the production process of high-voltage vacuum circuit breaker solid-sealed poles The existing deficiencies are that the insulating cylinder installation structure is adopted, and the vacuum interrupter is installed in an insulating cylinder. Although it can avoid ...
