Processing method for sealing gasket of vacuum arc extinguishing cylinder of high-voltage circuit breaker of intelligent power grid

Abstract

The invention relates to the field of intelligent power grids, in particular to a method for processing a sealing gasket of a vacuum arc extinguishing cylinder of a high-voltage circuit breaker of an intelligent power grid. The technical problem of the invention is to provide the method for processing the sealing gasket of the vacuum arc-extinguishing cylinder of the high-voltage circuit breaker of the smart power grid. According to the technical scheme, the processing method for the sealing gasket of the vacuum arc extinguishing cylinder of the high-voltage circuit breaker of the intelligent power grid adopts the following processing equipment. The machining equipment comprises a working machine tool plate, supporting foot columns, a notch discharging barrel, a mounting supporting column, a mounting middle-layer plate, a tilting flattening system, a pressing-down same-speed rotating system, a differential shrinkage convex system and the like. The lower portion of the working machine tool plate is welded to the supporting foot columns. Post-processing detection and repair treatment of the sealing gasket is achieved, the turnup position of the top edge of the sealing gasket is subjected to thermoplastic flattening again, the protruding part of the outer ring face of the sealing gasket is subjected to thermoplastic adduction, and the effect of the regular circular sealing gasket is achieved.

Description

technical field [0001] The invention relates to the field of smart grids, in particular to a method for treating the sealing pad of a vacuum arc extinguishing cylinder of a high-voltage circuit breaker of a smart grid. Background technique [0002] At present, in the prior art, in the process of assembling the high-voltage circuit breaker, in the process of assembling the vacuum interrupter, in order to ensure its airtightness, it is necessary to use rubber gaskets, but such gaskets are pressed and cut. When the pressing is uneven, the top of the cut circular gasket will be lifted, causing this gasket to be placed at the opening of the vacuum interrupter, and the raised position will form a path with the outside air, resulting in a vacuum The airtightness of the arc extinguisher decreases, and the outer ring surface of the gasket will have a raised part, which will cause the sealing cover of the vacuum arc extinguisher to fail to fit tightly, which will affect the vacuum env...

Problems solved by technology

[0004] In order to overcome the prior art in the assembly process of the high-voltage circuit breaker, in the assembly process of its vacuum interrupter, in order to ensure its airtightness, it is necessary to use a rubber gasket, but this gasket is pressed and cut. When the pressing is uneven, the top of the cut circular gasket will be lifted, causing this gasket to be placed at the opening of the vacuum interrupter, and the raised position will form a path with the outside air, resulting in a vacuum The airtightness of the arc extinguisher is reduced, and the outer ring surface of the sealing gasket will have a raised part, which will cause the sealing cover of the vacuum arc extinguisher to be unable to fit tightly, which will affect the vacuum environment of the vacuum arc extinguisher and cause power failure. Disadvantages, the technical problem of the present invention is to provide a method for processing the vacuum interrupter gasket of a smart grid high-voltage circuit breaker
