摘要

漏失熔断器以其结构简单、维修方便等特点在10千伏配电网中得到广泛应用。但使用一段时间后出现问题。提出了沿海地区引信的三种典型失效模式，以及相应的失效机理。为研究舟山电网50条退役引信在沿海地区的电气性能恶化情况，对其进行了试验，并设置了50条新引信进行对比。通过温升试验和接触电阻测量对漏电熔断器的电性能进行了评价。

Research on the Deterioration of Electrical Performance of Dropout Fuse

Dropout fuses are widely used in distribution network of 10 kilovolts for their outstanding characteristics of simple structure and convenient maintenance. However problems occur after a period of usage. Three typical failure modes of dropout fuses used in coastal area are proposed, as well as the corresponding failure mechanisms. 50 decommissioned dropout fuses from Zhoushan power grid were tested in order to study the electrical performance deterioration of dropout fuses used in coastal area, with 50 new dropout fuses set for comparison. Temperature-rise test and contact resistance measurement were carried out to evaluate electrical performance of the dropout fuses.
