通过局放诊断使ENDESA中压电缆的预防性维修最优化

本文介绍ENDESA配电公司的一种中压电缆的局放诊断系统 ,其结果能给出一张局放地图展示沿电缆全长在测试时发生局放的区段 ,局放大小和重复出现的频率。从而与电缆在电网中的功能和重要程度结合后制订一种分轻重缓急的有选择的维修行动以达到预期的目标 :降低维修成本 ,减少故障数目和提高供电质量。

Preventive maintenance optimization of ENDESA MV underground cables through partial discharges diagnosis

This paper introduces a partial discharges diagnosis system for MV underground cables in ENDESA DISTRIBUTION CO. of Spain,The result of which gives out a PD activity map, which shows the location, magnitudes and repetition of the PD appearing along the cable during test? In combination with the function and degree of responsibility of the cable in network, a selective and priority action for preventive maintenance may be worked out to conduce to the expected profit in terms of the target: to reduce the maintenance costs, number of failures and to improve the quality of the service?
