| 摘 要： | 为检验苏南500 kV UPFC工程现场的电子式互感器性能,对尚未正式投运的电子式互感器开展现场试验。提出了对电子式互感器的直流精度和阶跃响应性能进行测试的方法,使用自备的信号源产生一次电流信号,作为被测互感器和标准互感器的输入,使用互感器校验仪接收两者的输出并进行对比分析。结果表明,工程现场使用的电子式互感器性能良好,满足投运要求。同时,试验结果也证明了所用试验装置和方法的实用性,为后续进行系统的电子式互感器现场试验提供参考。

| Abstract: | Field tests are conducted on the electronic transformers in Sunan 500 kV UPFC project in order to examine their performance.Test equipment and method are presented referring to DC accuracy test and transient step test.A signal source is employed to produce primary current signal as the input of transformers to be tested and the standard transformer.A transformer tester is applied to receive the output signals of the two which are compared and analyzed accordingly.Test results show that performance of the transformers utilized in the project meet the requirements of operation.In addition,the test verifies the practicability of the equipment and the method.It can provide reference for further tests on the transformers. |
