摘要
为了降低拆除高压引线对设备造成的伤害以及提高检修效率,针对220 kV叠装式CVT的结构特点,介绍了不拆高压引线测量其介损及电容量的试验方法,分析了测量原理,提出了试验数据的处理方法。通过与拆引线试验的数据对比,证明该试验方法和对试验数据的处理方法是正确的。
In order to reduce the equipment damage caused by dismantling the high voltage down - lead and improve the examining and repairing efficiency, according to the construction feature of 220 kV integral type CVT, this paper presents a method for testing dielectric loss and capacitance without dismantling high voltage （HV） lead, analyses the testing principle and error, and proposes a data-processing method. The testing and data-processing method is verified by comparing the test data with dismantling HV lead.
