Working mode and energy storage time of vacuum circuit breaker energy storage motor

Sep 15, 2018

A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close and carry current under the abnormal loop conditions within a specified time. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off circuits when they are severely overloaded or short-circuited or under-voltage faults. Their functions are equivalent to fuse switches. Combined with over-heat relays and the like. In order to ensure the stability and safety of the circuit, a vacuum circuit breaker energy storage motor is needed.


The vacuum circuit breaker energy storage motor is used for spring energy storage type high and low voltage circuit breakers to provide energy for switching mechanism switching. When the switch is opened, the spring releases energy, the vacuum circuit breaker energy storage motor starts to work, and the motor stops when the spring tensile storage energy is in place.


The vacuum circuit breaker energy storage motor generally adopts a 220V AC/DC dual-purpose motor, which is short-time working system and is generally represented by D in the circuit. Its energy storage time is divided into two situations. One is to use the energy storage button. Press the energy storage button first. After the energy storage is finished, the switch can be pressed. It is called “pre-storage energy”; This means that the energy storage and closing are automatically completed after the closing button is pressed.
