摘　　要：为了提高电动汽车充电桩装表送电前、后的用电线路准确性,进一步提升电动汽车业务办理效率和使用规范性,分析了充电桩用户侧线路与其车位对应关系排查过程中的难点。通过对比充电桩与普通居民用户串户排查的差异,提出了一种低压用户隐蔽线路智能排查装置,通过智能排查装置的主机自激、功放电路放大,向用户侧线路注入特定的报文信号,并由从机接收并检测相关信号,实现充电桩用户侧线路与其车位的对应关系。In order to improve the accuracy of the wires before and after the installation of electric meter,and to further improve the efficiency and standardization of the electric vehicle business,this paper analyzes the difficulties in the process of checking the corresponding relationship between the user side line of the charging pile and its parking space.In this paper,by comparing the differences in checking the corresponding relationship between the charging pile and residential electricity,an intelligent detection device for hidden lines of low-voltage users is proposed.A host machine injects a specific message signal into the user-side line through the self-excitation and power amplifier circuit amplification,and a slave machine receives and detects the relevant signal.The master-slave machine realizes the detection of the corresponding relationship between the user side line of the charging pile and its parking space.
