In order to solve the problem of low switching speed and reliability of circuit breaker with traditional operating mechanism,a large capacity high-speed switch based on eddy current drive is proposed. The fast switch uses electromechanical integration instead of traditional mechanical transmission mechanism. The switching speed and reliability are greatly improved by using eddy current drive technology,fast detection technology,non-rebound switching technology and zero-crossing switching technology. The performance test of device shows that large capacity high-speed switch based on eddy current drive is superior to the traditional circuit breaker in the aspects of switching speed,switching capacity,mechanical life and short circuit current suppression.
