摘要：对电气线路进行接地故障保护，方式接地故障电流引起的设备和电气火灾事故越来越成为日常。针对用户侧主要的用能节点，设计安装剩余电流继电器，实时监控各用能回路的剩余电流状态。通过实时监控用能以及相关电力参数、提高用能安全、可靠及维护效率、降低维护的人工成本、实现了对剩余电流监控的无人值守。通过用能的实时监测，数据的采集及报警，监测配电系统中剩余电流，为用户电气线路接地故障保护，防范剩余电流导致的火灾事故和人员触电事故提供保障。现就我司ASJ型剩余电流继电器在马尔代夫环岛水上排屋项目的应用做一简要介绍。

Abstract: Ground fault protection for electrical circuits, equipment  and electrical fire accidents caused by ground fault currents are  increasingly becoming a daily necessity. For the main energy-consuming  nodes on the user side, a residual current relay is designed and  installed to monitor the residual current status of each energy-using  circuit in real time. Through real-time monitoring of energy use and  related power parameters, the safety, reliability and maintenance  efficiency of energy use are improved, the labor cost of maintenance is  reduced, and the unattended monitoring of residual current is realized.  Through the real-time monitoring of energy use, data collection and  alarm, the residual current in the power distribution system is  monitored, and the ground fault protection of the user's electrical  circuit is provided to prevent fire accidents and personal electric  shock accidents caused by residual current. Here is a brief introduction  to the application of our company's ASJ residual current relay in the  water terrace house project around the island Maldives.


1.项目概述  Project Overview

马尔代夫环岛水上排屋主要用于接待世界各地游客，应用现场频率为50  Hz，电压为220V的TT或者TN系统配电线路。客户希望通过在水上排屋配电柜内安装剩余电流继电器来监测线路剩余电流，并且希望可以在显示面板上显示实时监测的剩余电流值与其设定的剩余电流值之比值，在此比值达到80%时剩余电流继电器能立即报警。安科瑞ASJ10-LD1A配合剩余电流互感器，成功地解决了客户现场剩余电流监控需求。

The water townhouses around the island in the Maldives are mainly used  to receive tourists from all over the world. The application site  frequency is 50 Hz and the voltage is 220V TT or TN system power  distribution lines. The customer hopes to monitor the residual current  of the line by installing a residual current relay in the distribution  cabinet of the water row house, and hopes that the ratio of the  real-time monitored residual current value to the set residual current  value can be displayed on the display panel, when the ratio reaches 80%,  the residual current relay can alarm immediately. Acrel ASJ10-LD1A  cooperates with the residual current transformer, Successfully solved  the customer's on-site residual current monitoring needs.
