串联谐振试验原理及设备耐压试验中常见问题分析

Common Problem Analysis on Series Resonance Test Principle and Equipment Pressure Test

运用串联谐振原理,利用较小容量的供电电源可完成等效于供电电源30～150倍容量的试验,解决了现场试验电源的容量不足问题,适用于大容量、高电压试品的交接耐压试验和预防性试验。青岛供电公司串谐设备主要应用于110 kV以上电缆及GIS交流耐压试验。在近几年的试验中,遇到了由试验设备或被试品异常引起的种种的问题,对这些问题进行总结归纳并对原因进行分析。

By using the series resonance theory, the capacity of the power supply can accomplish the equivalent to the power supply 30-150 times capacity test, solves the test power supply capacity lack problem, suitable for large capacity and high voltage test. In Qingdao power supply company, series resonance equipment is mainly applied to 110 kV above cable and GIS exchange pressure test. In recent experiments, we met at the scene by test equipment or caused by abnormal try product variety of problems of these problems, this paper summarizes the problems and the reason is analyzed.
