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 earth leakage relay in the Philippine mine.

1.項(xiàng)目概述  Project Overview

該礦廠位于菲律賓，由于電流很大，礦廠用電情況特殊，客戶希望通過在配電柜內(nèi)安裝剩余電流繼電器來監(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，成功地解決了客戶現(xiàn)場(chǎng)剩余電流監(jiān)控需求。由于現(xiàn)場(chǎng)電流很大，所以在剩余電流互感器的選擇上，我們進(jìn)行了多次溝通，通過銅排以及電流規(guī)格給客戶選定了合適的剩余電流互感器。

The mine factory is located in the Philippines, because the current is very big, electricity supply for mine is special , customers hope that through in the power distribution ark installation of residual current relay to residual current monitoring line, and hope that can be displayed on the display panel real-time monitoring of residual current value rather than setting the ratio of residual current value, the ratio can reach 80% when the residual current relay immediately report to the police. Acrel ASJ10-LD1A with residual current transformer, successfully solve the customer's on-site residual current monitoring requirements. Due to the large current on site, we have communicated for many times on the selection of residual current transformer, and selected the most appropriate residual current transformer for the customer based on copper bar and current specifications.

• 【集中式電能表】常用電能表的分類

  電能表是用來測(cè)量電能的儀表，又稱電度表、火表、千瓦小時(shí)表，指測(cè)量各種電學(xué)量的儀表。使用電能表時(shí)要注意，在低電壓（不**過500伏）和小電流（幾十安）的情況下，電能表可直接接入電路進(jìn)行測(cè)量。在高電壓或大電流的情況下，電能表不能直接接入線路，需配合電壓互感器或電流互感器使用。分類（1）電能表按其使用的電路可分為直流電能表和交流電能表。交流電能表按其相線又可分為單相電能表、三相三線電能表和三相四線電能表。
