Specifically, the brake chopper plate 600 is connected in parallel with the power supply apparatus 300, and the brake chopper plate 600 is connected to the motor 100. The working principle of the braking chopper plate 600 for energy-consuming braking of the motor 100 is as follows: the reduction and stop of the speed of the motor 100 are realized by gradually reducing the frequency, and at the moment of reducing the frequency, the synchronous speed of the motor 100 is reduced, and the speed of the rotor inside the motor 100 is not changed in time due to the mechanical inertia. When the synchronous rotational speed is less than the rotor rotational speed, the phase of the rotor current is changed by almost 180 degrees, and the motor 100 is changed from the motoring state to the generating state; at the same time, the torque on the main shaft 110 becomes a braking torque, the rotation speed of the motor 100 is rapidly reduced, and the motor 100 is in a regenerative braking state. The two ends of the motor 100 are connected with a freewheeling diode in parallel, the electric energy regenerated by the motor 100 is fed back to the circuit after full-wave rectification through the freewheeling diode, and the electric energy of the circuit cannot be fed back to the power grid through a rectifier bridge and is absorbed only by the capacitor of the frequency converter, although the electric energy can be consumed by other parts, the electric charge on the capacitor still accumulates for a short time, so that 'pumping voltage' is formed, and the direct-current voltage is increased. Excessive dc voltage will cause damage to the components within the motor 100. Therefore, when the load is in the power generation braking state, corresponding measures need to be taken to deal with the part of the regenerative energy. Dynamic braking is one of the ways to process regenerative energy, and the method for dynamic braking may be to add a braking chopper plate 600 on the dc side of the frequency converter, where the braking chopper plate 600 generally includes a dynamic braking circuit and a power resistor, and the regenerative energy is consumed on the power resistor to implement braking. In the mode, the regenerated energy is consumed on the resistor through a special energy consumption braking circuit and is converted into heat energy, so that the mode is also called as 'resistor braking', and has the characteristics of small volume, good heat dissipation performance and safe energy release.

In one embodiment, the power protection device 200 is a residual current circuit breaker.

When an electric leakage protection circuit breaker is used as the power protection apparatus 200, a circuit can be rapidly cut off when an electric shock occurs to a human body or an electric leakage occurs to an apparatus, thereby preventing the human body and the apparatus from being harmed.
