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.項(xiàng)目概述 Project Overview
馬爾代夫環(huán)島水上排屋主要用于接待世界各地游客，應(yīng)用現(xiàn)場(chǎng)頻率為50 Hz，電壓為220V的TT或者TN系統(tǒng)配電線路。客戶(hù)希望通過(guò)在水上排屋配電柜內(nèi)安裝剩余電流繼電器來(lái)監(jiān)測(cè)線路剩余電流，并且希望可以在顯示面板上顯示實(shí)時(shí)監(jiān)測(cè)的剩余電流值與其設(shè)定的剩余電流值之比值，在此比值達(dá)到80%時(shí)剩余電流繼電器能立即報(bào)警。安科瑞ASJ10-LD1A配合剩余電流互感器，成功地解決了客戶(hù)現(xiàn)場(chǎng)剩余電流監(jiān)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.
