摘要
配电线与引下线之间的连接部分由于受到污损所造成的绝缘性能的下降，是柱上变压器附近的电线表面发生局部放电的主要原因之一。为了提高该部分的绝缘能力，采用在绝缘电线上涂硅油的方法，对不同条件下绝缘电线的耐电压特性进行了试验研究和分析。
One of Causes of local wire-surface discharge near the on-pole transformer lies in the fact that the insulation of the connection between thd distribution conductor and the lead wire decreases due to its pollution damage.This paper presents a measure to improve the insulation ability of the connection by adding a silicone coating to the insulated wire,and tests are made on measurement of surface impedance of the insulated wire under different weather conditions.
