Spring charging motor on 11kV Circuit breaker
Spring charging motor on 11kV Circuit breaker
(OP)
We have a circuit breaker with 110DC spring charging motor. It is to be used in a switchboard where the the supply is 220VAC. Can we use an industrial type converter (220Vac-110Vdc) of suitable rating to supply power to the charging motor,instead of replacing the motor itself.
thanks in advance for your valuable feedback

Not to mention the auxiliary supply needed for protection equipment.

What is the breaker type? A photo of the nameplate would be helpful here.

This is also going to depend on how critical the circuit is.

What David saied.
Spring charging motor isnt issue, possible use some convertor, possible use some step-down transformer 220/60-63V and diode bridge.
We have a lot of application were motor is feeded by 220V AC and trip and close coils from 110-220V DC.
Capacitive device is good solution too, if feeded from UPS and CT, or from VT and CT.
Best Regards.
