In order to develop the disconnector operating device for large capacity generator circuit breaker with independent intellectual property rights

a pair of series-wound DC motor drive power transmission device has been developed

and the device has high torque output and short-time operation ability.The test results show that: the use of DC series motor soft characteristics

using double series-wound DC motor drive

double worm gear drive

single shaft output driving mode can meet the high capacity generator circuit breaker

disconnector with actuating device technical requirements.In the operating device DC series motor output torque unchanged case

through reducing the series excitation DC motor speed

the rebound phenomenon

which caused by the disconnector tripping speed

can be eliminated.Added a time delay relay in control circuit

the electromagnetic clutch electric slipping phenomenon can be eliminated.
