多回路起动器非在线绝缘检测装置

The Non-online Insulated Checkout Device of Multiloop Starters

本装置可同时检测多回路绝缘阻值,根据绝缘阻值检测范围和工作机制的不同,装置分为漏电闭锁检测和绝缘预警检测两部分,其绝缘电阻值由装置采用附加直流检测的原理进行采样,并经单片机计算,低于保护值时输出控制信号。

The device can check mutiloop inscdation resistance simultaneously according to differences of the insulation resistance checking range and working machine-processed. The device is divided into parts of the leakage blocking detection and the insulated early warning detection. Its insulat resistance is canried out by the principle adding DC of the device and through single chip calculation, less than output control signal at protection value.
