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.

This series of products can be classified as 12kV and 40.5kV according to the voltage level. Due to the small number of parts and the use of advanced intelligent controller for control operation, it has been welcomed by users once launched. This series of products have been successfully applied to domestic power distribution and distribution network projects (power supply systems in Hunan, Hebei, Jiangsu, Shandong, Fujian, Gansu, Shanxi and Liaoning) and metallurgy Mining, construction, chemical industry, new energy and other projects.
