|
摘要
为定期检查发电机转子过电压保护装置工作性能,提出了一种利用现有的低压设备测试转子过电压保护装置实际动作值的方法:通过测量触发器的动作电压,计算出转子过电压保护装置的实际工作值。经验证,该方法的检测结果与常规方法一致,操作简单,测试过程无高压,可作为一种发电机转子过电压保护装置的快速检测方法,确保发电机可靠运行。
To regularly detect the performance of generator rotor overvoltage protection device,a method of using the existing low voltage equipment in testing the actual operating value of rotor overvoltage protection is put forward: by measuring the operating voltage of the trigger,then the actual operating value of the rotor overvoltage protection device can be calculated. It is verified that the method of the test results agree with conventional methods. The operation is simple and there is no high voltage in the process. It can be used as a rapid detection method on the generator rotor overvoltage protection device to ensure the reliable operation of the generator.
