直流電能表在充電樁計量行業的應用 2023-03-28 14:38:41 安科瑞電氣股份有限公司

基本信息項目名稱: 直流電能表在充電樁計量行業的應用項目地點:

應用場景

功能

總進線回路配置電能質量分析儀，對整個充電樁供電回路電能質量進行監測，同時設置漏電流監測裝置。充電回路采用三相供電，其進線采用交流塑殼斷路器。三相主回路配置剩余電流繼電器，提供間接接觸的觸電保護。由于此類充電樁消耗功率大，故建議在其三相交流回路配置導軌式電能表用于計量總電能，配合直流電能表對整個充電站的運行效率進行監控。充電管理控制器負責外部人機接口，充電控制，讀取直流電能表的電能數據，控制直流充電輸出斷路器的分合閘等。

系統結構圖

直流充電樁中需要安裝直流電表，來測量充電電壓和充電電流以及統計充電電量，并通過RS485總線與控制模塊進行通信。
