机场助航灯回路绝缘电阻检测硬件电路设计

摘要

In allusion to the safety issue of airfield lighting circuit, the airfield lighting circuit insulation resistance test hardware was designed. Introduction was made to the principle of insulation resistance test. This paper gave two main hardware circuit design methods including a DC high-voltage measurement circuit and a collection quantity transfer circuit. Test result shows that the circuit can complete measurements quickly and correctly with limited errors, having reached satisfactory effect.%针对机场助航灯回路的安全性问题，设计了机场助航灯回路绝缘电阻检测硬件电路。介绍了绝缘电阻检测的原理，给出了直流高电压测量电路和采集量转换电路两个主要的硬件电路设计方法，测试结果表明，该电路能快速准确地完成测量，误差在允许范围内，达到了满意的效果。
