真空断路器操作过电压对电机产生的危害及对策

通过对真空断路器操作过电压的产生机理以及我国目前生产的保护设备技术参数的计算分析和计算，提出了真空断路器产生截波过电压对电机产生的危害和应采取的措施以及装设过电压保护器后对电机产生的影响，特别在电机回路中应用真空断路器时，除具有完善的保护措施外，还应注意的一些其它问题，以使真空断路器的优良性能得到充分发挥。

The Dangers and Solutions to the Motors due to Vacuum Circuit-Breaker Operational Over-Voltages

Via mechanism for taking place by the vacuum circuit-breaker operational over-voltages and the calculation and analysis to the protection eqipment' s technical date produced presently in our country, it raises the dangers and solutions to the motors due to vacuum circuit-breaker in operation to produce cross-wave over voltages; and the impacts on the motors with installation of over-voltage protectors especially in the motor circuit where circuit-breaker is applied, except with complete protection actions, some other questions should be also paid with attention to make the fine performaces of vacuum circuit-breaker to make full play.
