In order to improve the controllable of high voltage circuit breaker and enhance the reliability of motor operating mechanism control system, the segment adjustment permanent magnet motor operating mechanism is studied to realize the different speed requirements in the opening and closing motion process for high voltage circuit breaker. The segment voltage starting motor and variable air-gap structure...
A novel motor operating mechanism is presented which applied in the high voltage circuit breaker. The new motor is a permanent magnet motor with limited angle and only working in the starting stage. Based on the requirement of high voltage circuit breaker, the structure and parameters of motor are designed. The dynamic simulation of permanent magnet motor are achieved by employing the finite element...
To improve the interoperability and controllable of high voltage switch equipment, this paper puts forward the motor driver operating mechanism which applied to the circuit breaker. Developed prototype motor and drive control system, established the test system platform, selected the sensors, completed the dynamic characteristics testing. The experimental results show that the motor meet the requirements...
