Introduction

The technical content of this standard is based on GB /Z6829-2008 "Residual current action protection electrical general requirements", GB 14048.2- 2008 "Low-voltage switchgear and controlgear - Part 2. Circuit breakers" and GB 14048.5-2008 "Low-voltage switchgear and controlgear Part 5-1. control circuit electrical and switching elements electromechanical control circuit electrical appliances "and other standards related to the preparation. Residual current operated relay

1 Scope

This standard specifies the type, classification, characteristics, and marking of the residual current operated relay (hereinafter referred to as residual current relay). Conditions, installation conditions, structure, performance requirements, test methods and inspection rules. The residual current relay specified in this standard is suitable for use in distribution lines with AC rated voltage of 400V and below. Measure the ground fault current in the line. Note. The relevant part of this standard can also be used to guide the AC rated voltage to 1200V residual current relay. The residual current relay specified in this standard refers to the simultaneous completion of the detection of residual current, the residual current compared with the reference value, and when When the residual current exceeds the reference value, a mechanical opening and closing signal is issued, including the residual current transformer and the control part Body residual current relay and residual current transformer and control part are installed separately, but are divided together by electrical connection Body residual current relay. The residual current relay specified in this standard can be assembled with a low-voltage circuit breaker or a low-voltage contactor into a combined residual current protector, Used to protect the electrical circuit ground fault, to prevent ground fault caused by the current equipment and electrical fire accidents can also be used to touch the human body Electrical hazards provide indirect contact protection. The residual current relay specified in this standard can also be used with sound and light alarm devices to monitor the residual current monitor, used to monitor the electrical circuit Ground fault current. When the rated residual operating current is less than or equal to 0.5A, it can also be used as a residual current fire monitoring device for monitoring Depending on the system ground fault current, to prevent electrical fault caused by ground fault current. This standard does not apply to relays with overload protection.
