摘要
电子式电流互感器是建设智能电网的关键设备,其稳定、可靠性是智能电网安全运行的重要保证。本文针对电子式电流互感器在与断路器耦联振动下的试验方法进行了研究,提出了两种可行的试验方法,并在两种试验方法下对电子式电流互感器的振动特性进行了研究,进而分析了振动对电子式电流互感器输出影响的原因。
The electronic current transformer （ECT） is the key device of the smart grid, the reliability and stability of which ensure the security of the smart gird. So this paper investigates the test method of the ECT vibrating which is from connecting to the circuit breaker when operating, and proposes two methods. It also tests the ECTs in these two methods, and analyzes the causes of the error output of ECTs on the basis of the test results.
