二次回路交流阻抗测试仪的开发

Development of Secondary Loop AC Impedance Tester

电网的安全稳定运行,除了一次设备外,还需要各种各样的二次设备。二次回路发生故障可能会导致电力设备无法正常工作,尤其是继电保护的二次设备回路众多,不符合规范要求常常造成二次回路出现故障,导致事故发生,因此规范继电保护二次回路对于确保继电保护装置安全稳定运行是非常重要的。

In order to ensure the safe and stable operation of the power grid, in addition to the primary equipment, a variety of secondary equipment is required. Therefore, failure of the secondary circuit may cause the power equipment to fail to work normally, especially in the relay protection. There are many ways to add equipment, and failure to meet the requirements of the specification often causes the secondary circuit to malfunction, resulting in an accident. Therefore, it is very important to regulate the secondary circuit of relay protection to ensure the safe and stable operation of the relay protection device.
