Ordinary spring mechanism is widely used in vacuum circuit breaker in the market, and its mechanism quality is uneven. Due to the complex mechanism and many parts, the tripping system and transmission system of the original spring mechanism are limited by domestic technology. When it is actually used for one or two thousand times, the operating mechanism of the circuit breaker has continuous faults and the phenomenon of refusing to open and close is serious; The common fault of the circuit breaker is that the opening and closing coil and auxiliary switch are burned, and the circuit breaker often refuses to open and close due to the fault of the half shaft tripping system; Therefore, many domestic manufacturers continue to improve and innovate the organization.
