The invention relates to the technical field of vacuum circuit breakers, in particular to a vacuum circuit breaker contact operating mechanism which comprises a base, a circuit breaker body, a conductive protrusion, a conductive trigger block, a first motor and a switch triggering piece, wherein the circuit breaker body and the first motor are both mounted on the base; the conductive protrusion is fixedly mounted on the circuit breaker body; the conductive trigger block is connected with the circuit breaker body through an elastic telescopic rod; the side, away from the conductive protrusion, of the conductive trigger block is an inclined face; the switch triggering piece comprises a mounting bracket and a roller rotationally mounted on the mounting bracket; grooves matched with the rollers are formed in the inclined surfaces; the base and the rollers are made of insulating materials; and the first motor is connected with the switch triggering piece and used for driving the rollers to move along the grooves so as to push the conductive trigger block to move in the direction close to the conductive protrusion till the conductive trigger block makes conductive contact with the conductive protrusion. The vacuum circuit breaker contact operating mechanism effectively solves the technical problem that an electric shock risk exists in the operation process of an existing circuit breaker.
Description
technical field [0001] The present application relates to the technical field of vacuum circuit breakers, in particular to a vacuum circuit breaker contact operating mechanism. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. [0003] Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse-type switch. ...
