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。该系统能及时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 that controlled by 8031 single -ehip computer is introduced in this article. This systyem can analyse the changes of leakage active current of lightning arrester in time to judge whether the lightning arrester is ageing. If a lightning attester is ageing,the system will alarm automatically then show the position of ageing arrester, so the ageing an＇ester will be replaced in time.
