摘要

作动器用于驱动触点运动，以完成高压断路器的开关动作。电机驱动执行器由于结构简单、可检测性、可控性和智能化高，被认为是传统执行器的最佳选择。本文以永磁同步电动机驱动126kV真空断路器为研究对象。对该装置进行了运动学和动力学分析，并在Matlab/Simulink平台上建立了数学模型。然后根据真空断路器的预期工作性能，计算了永磁同步电机的技术参数要求，包括转矩需求、转子转速和轴负载特性。最后，研制了永磁同步电动机驱动真空断路器样机。通过样机试验，验证了数学模型和计算结果的可靠性。

Research on Technology of 126kV Motor Drive Vacuum Circuit Breaker

Actuators are used to drive the contact movements to complete switching actions of high voltage circuit breakers(HVCB). Motor drive actuator is considered better than conventional actuators due to its simple structure, high detectability, controllability and intelligence. This paper takes Permanent magnet synchronous motor(PMSM) drive 126kV vacuum circuit breaker(VCB) as research object. The kinematic and dynamic analysis of the device are carried out, and the mathematical model is established on Matlab/Simulink platform. Then based on the intended working performance of the vacuum circuit breaker, the requirements of PMSM's technical parameters are calculated, including torque demand, rotor speed and shaft load characteristics. Finally, the prototype of PMSM drive vacuum circuit breaker is developed. The reliance of the mathematical model and the calculation results are verified through the prototype tests performed.
