摘要:
 为探索干式空心电抗器匝间过电压现场试验的可行性,同时考虑被试设备已运行一定的年
限,用70%出厂试验电压,对某变电站27 台35kV 干式空心电抗器进行了匝间过电压现场试验。
检测出2 台具有匝间绝缘缺陷的被试设备,证实了在现场进行干式空心电抗器匝间绝缘过电压试
验的可行性和必要性。通过对现场试验过程中遇到问题的分析,发现在试验中存在设备地电位抬
高现象,为尽量降低地电位的浮动,提出了现场试验合理的接线方法,可为匝间过电压现场试验提
供指导。
Abstract:
 In order to explore the feasibility of turn-to-turn over-voltage test on dry-type air-core reactors
in the field,simultaneously considering the tested equipments runned a certain age,27 sets 35 kV drytype
air-core reactors in substation were tested under 70% factory test voltage. Two tested equipments
were detected having turn-to-turn insulation defects,which confirmed the feasibility and necessity of making
turn-to-turn insulation over-voltage test for dry-type air-core reactors in the field. By analyzing the
problems during the field test,ground potential elevation phenomenon existed in the test. In order to decrease
the floating of ground potential,reasonable wiring way in the field test was proposed which provides
guidance for the turn-to-turn over-voltage test in the field
