Monitoring technology of energy storage motor for VD4 mechanism

The secondary circuit of the energy storage motor for VD4 mechanism includes a DC power control switch, an energy storage motor and an energy storage motor control switch, wherein the DC power control switch is connected to the DC bus to cut or close the total current; the energy storage motor and the DC power supply Control switches are connected in series. In this case, as long as the energy storage motor can be separately controlled, it can avoid the burning of the auxiliary plug due to poor contact when the vacuum switch is sent from the "test position" or the "maintenance position" to the "working position", eliminating the VD4 mechanism. Hidden dangers on the secondary circuit of the energy storage motor.

 

At the same time, an improved method for voltage monitoring of energy storage motor loops is proposed for the energy storage motor of VD4 mechanism. A voltage monitoring relay can be installed at the power supply of the circuit breaker terminal energy storage motor. The voltage relay power input determines that the circuit breaker energy storage motor power supply has no pressure or under voltage condition, and then accesses the circuit breaker energy storage motor power supply through the auxiliary contact point to open the auxiliary contact point.

 

When the upper limit of the circuit breaker energy storage motor power supply is tripped or the voltage is under voltage, the voltage monitoring relay can be sent through the auxiliary voltage contact relay to judge the state of the voltage of the energy storage motor circuit of the VD4 mechanism, and the abnormality will be timely. The signal is fed back to the monitoring background, which is convenient for finding out in advance that the VD4 mechanism uses the energy storage circuit loop power supply.

 

The VD4 mechanism uses the energy storage motor to install the voltage monitoring relay, which not only improves the stability and reliability of the equipment operation, but also ensures the safe operation of the equipment. The voltage monitoring relay can prevent the power supply fault of the energy storage motor of the VD4 mechanism in advance, and remove the safety hazard.
