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安裝剩余電流繼電器來監測線路剩余電流，并且希望可以在顯示面板上顯示實時監測的剩余電流值與其設定的剩余電流值之比值，在此比值達到80%時剩余電流繼電器能立即報警。安科瑞ASJ10-LD1A配合剩余電流互感器，成功地解決了客戶現場剩余電流監控需求。由于現場電流很大，所以在剩余電流互感器的選擇上，我們進行了多次溝通，通過銅排以及電流規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.
