Development of Online Detection Device for Lightning Arrester with Gap in Distribution Networks
摘要
Abstract
As one of the most effective equipments for lightning overvoltage protection in distribution lines,series gap surge arresters are widely used in overhead lines of distribution networks.Some lightning arresters fail during operation,and when subjected to lightning strikes,they are prone to pressure release and cause line tripping or damage to insulators and wires.The change in the performance of arrester after seal deterioration is analyzed and the insulation resistance value is selected as the basis to judge the health status of arrester.The technical requirements of online detection device for gap arresters in distri-bution networks are put forward.An online detection device for gap arresters in distribution networks is developed,which can detect the health status of gap arresters,find the seal deteriorated arrester in ad-vance,and enable the operation and maintenance personnel to replace the fault arrester in time,reducing the circuit trip or other operation accidents caused by the damage of lightning arrester.关键词
