The Energy storage motor for VD4 mechanism is mainly used for the energy storage closing of the universal circuit breaker. Because the circuit breaker is required to open and close, the circuit breaker has an energy storage spring. The energy storage motor of the VD4 mechanism adds elastic potential energy to the spring. Its voltage is 220V and 380V; the power range is 80W-360W; the speed is 73r/pm--2000r/pm, which is differentiated according to the model.
This is true when the VD4 mechanism starts to work with the energy storage motor and the spring is stretched to store energy. When the circuit breaker is closed, the energy of the spring is completely released from the breaker contacts and closed. At this time, the energy storage motor should work again to store energy. When the brake is opened, only the release contact of the trip unit can release, and the spring energy is not released. That is to say, the brake is not used, and the energy of the energy storage spring is not used, and the energy can be opened regardless of the energy storage.
The energy storage motor of the VD4 mechanism is also called a series excitation motor. The electric operation mechanism has two kinds of electric operation mechanism and electromagnetic operation mechanism: the electric operation mechanism is driven by an electric motor, and is generally suitable for operation of a large-capacity circuit breaker of 400A or more; electromagnetic operation mechanism Driven by an electromagnet for small capacity circuit breakers.
