摘要
电子式互感器暂态特性必须采用直接法进行测试,现有的测试方法投资大、试验控制复杂,并不适合工程化的现场应用,针对该问题,提出了一种以三套电源装置为核心的暂态特性测试系统,测试系统通过计算机进行波形的计算、分解以及组合控制,提供宽范围的调节能力,合成一次侧全偏移暂态电流。该试验装置能够提供真实的暂态电流试验条件,对互感器的出厂检验和高压电力系统交接试验具有一定的指导意议和应用价值。
The transient characteristics of electronic transformers must be tested by the direct method. The existing test methods have large investment and complicated control,which is not suitable for the field application. In order to overcome this problem,the test system which adopts three sets of power source devices is introduced through the computer waveform calculation,decomposition and combination of control,the transient characteristics of the test system provided a wide range of regulation capacity and composited the all-offset transient current. The test device can provide a true current test conditions. The test system can be used in factory test or delivery test for transformer in high-voltage power system has some guidance and application value.
