Abstract :
A single break 126 kV vacuum circuit breaker debuted in China is introduced. Configuration of 126 kV vacuum circuit breaker and configuration of its electrode are illustrated. Particularly, silicone oil is used as external insulation of vacuum interrupters. Heat radiators are designed for raising rated current. Permanent magnet actuators with long stroke are developed for improving performance of the vacuum circuit breaker
