Abstract
A permanent-magnetic operation vacuum circuit breaker comprises a vacuum arc-extinguishing chamber. A static contact and a moving contact are arranged in the vacuum arc-extinguishing chamber. A vertical pull rod is connected with a first crank. One end of the first crank is connected with a second crank and a pull rod. The pull rod is connected with a guide shaft of a permanent magnetic mechanism. An information input terminal of the permanent magnetic mechanism is connected with an information output terminal of a controller of the permanent magnetic mechanism. When opening and closing operation are carried out, control command enters through a communication module of the controller of the permanent magnetic mechanism and is sent to an opening coil or a closing coil, so that opening (closing) speed of the vacuum circuit breaker is relatively low. When the permanent-magnetic operation vacuum circuit breaker carries out fault opening, the control command is sent to a special-purpose control chip and the special-purpose control chip doesn't modulate coil current signals at the moment and sends the coil current signals to the opening coil without any time delay, so that the vacuum circuit breaker can perform opening operation at the fastest speed and service life of the vacuum circuit breaker is prolonged.
