The application of the high-voltage vacuum circuit breaker in our power supply system began in 1978. Its light weight, simple structure, long service life and other advantages were quickly recognized by the power department operation, overhaul and technicians. The quality of the early domestic high voltage vacuum circuit breaker is not stable enough, the on-load voltage is high in the operation process, and there is leakage phenomenon in some vacuum arc extinguishing chambers.

The processing and manufacturing industry of low-voltage switchgear is a key component of the power transmission and transformation equipment processing and manufacturing industry, and plays a crucial role in the entire power industry. The key components of switchgear include high-voltage circuit breakers, voltage transformers, locally installed microcomputer relay protection equipment, actual operation control circuit accessories (door handles, display lights, pins), and auxiliary power switches from various manufacturers of switchgear.
