Circuit breaker dedicated AC and DC dual-use energy storage motor

The operating voltage range of the AC/DC dual-purpose energy storage motor for the circuit breaker is 220V-380V, which can be applied to a plurality of different series of circuit breaker energy storage closing operations. In addition, some energy storage motors can be used for vacuum circuit breakers. Circuit breaker energy storage motor is mainly used for closing and opening.

 

Then, in actual work, how is the energy storage function achieved? In general, there are two ways to store energy in circuit breakers. One is manual energy storage, and the other is energy storage energy storage. The ultimate goal of both types of energy storage is to stretch the spring and store energy in the spring. Manual energy storage is generally used only during maintenance or when there is no control power supply in an emergency.

 

In fact, we can regard the closing mechanism of the circuit breaker as a kind of tripping mechanism, and the closing or opening of the circuit breaker requires the mechanism to provide sufficient operating energy. The energy storage motor mechanism will store the spring energy before closing. Stretching or compressing) and stabilizing the mechanism at a dead point. When the closing mechanism is closed, the energy storage mechanism is released from the dead point to quickly release the spring energy, and the closing is completed. At the same time, the closing spring is the energy storage of the sub-gate spring. When the sub-gate mechanism is tripped, the sub-gate is completed.

 

From this it can be seen that if you want to close, then you must first store energy. Therefore, it is often necessary to use a stored energy motor. A circuit breaker with an automatic reclosing function can also store energy after the closing is completed (the stored energy spring is released), and the rapid reclosing function can be completed. Usually we can call it "motor". Electro-mechanism includes two kinds of electric operating mechanism and electromagnetic operating mechanism.

 

The former operating mechanism is mainly driven by electric motors. At present, most of them are used for the operation of large-capacity circuit breakers of 400 A and above, and the use of energy storage motors to achieve the purpose; and the electromagnetic operating mechanism is driven by an electromagnet, usually used for 100 A. , 225A and other small-capacity circuit breakers. And for different specifications of the use requirements, users can choose the appropriate energy storage motor.
