直流系統絕緣接地巡檢裝置

摘要：本文以應用改進的直流電橋法為基礎，以89C52單片機作為主控芯片,配上其它外圍設備構成直流系統絕緣電阻在線巡回檢測裝置，對直流系統進行接地檢測。該裝置通過對母線的接地檢查和支路的接地檢查，測得數據，經過處理，自動的顯示接地故障支路，從而實現了直流系統絕緣接地巡檢裝置的自動化和智能化。該裝置簡單、實用、可靠。 敘詞：改進的直流電橋法 單片機 直流系統 接地檢測 Abstract：A online DC system insulation resistor measuring device controlled by 89C52 with peripheral devices,which is based on the improved DC bridge method,is introduced in this paper.With such simple,practical and reliable device,the automation and intelligence of DC system insulation measuring device could be realized successfully.
