摘要
介绍一种使用８０３１单片微机控制的高压避雷器在线监测装置。该系统及进分析避雷器有功泄漏电流的变化情况，以判断高压避雷器是否老化或劣化，若检测到劣化避雷器时自动报警，自动显示劣化避雷器部位，便于及时更换。
A high voltage lightning arrester on - line monitoring devices thatcontrolled by 8031 single - chip computer is introduced in this article. This systyem cananalyse the changes of leakage active current of lightning arrester in time to judge-whether the lightning arrester is ageing. If a lightning arrester is ageing, the systemwill alarm automatically then show the position of ageing arrester, so the ageing ar-rester will be replaced in time.
