摘　　要：根据220kV电容式电压互感器(CVT)结构、原理和状态检修的要求,提出了一种不拆高压引线的例行试验新方法。详细介绍了新方法的例行试验接线,通过逐项误差分析,论证了新方法的正确性,实例验证了新方法的有效性,不同型号的CVT抽样对比试验说明新方法具有推广价值。Based on structure, principle and condition-based maintenance requirements of 220 kV capacitor voltage transformer （CVT）, a new routine test method of CVT without removing the HV lead conductor is put forward. The wiring of routine tests is introduced in detail and the correctness of this method is demonstrated through error analysis of each test, and its effectiveness is verified by Examples. The sampling test among different types CVT shows the new method can be generalized.
