One 、 Product overview
CLJ3 Residual current operated relay （ Hereinafter referred to as relay ） Suitable for AC voltage to 660V Or higher TN、TT、 and IT System , The frequency is 50Hz. Detect the zero sequence current exceeding the setting value through the zero sequence current transformer （ The remaining ） Leakage current . The relay is connected with the circuit breaker of shunt release or voltage loss release 、 AC contactor 、 Magnetic starter and other components of leakage protection device , For leakage and electric shock protection , Can be equipped with buzzer 、 Signal and other acoustooptic devices are combined to form a leakage alarm device . Derive multiple models , Prefix such as HLJ、RLJ、ULJ Series and other models , It is actually a similar product . It plays a very important role in the power system , It is the basis to ensure the reliability of power supply .
Two 、 Product use
The leakage protection relay has small volume 、 Easy to install and use 、 Reliable movement 、 Continuous power supply is stable and easy to operate . Can adapt to users everywhere , It can be used to protect the line from ground fault , It is mainly used to prevent equipment accident or electrical fire caused by grounding fault current , It can also be used to provide indirect contact protection for the release of human electric shock .
The leakage relay can be connected with the circuit breaker with shunt release or voltage loss release 、 AC contactor 、 Magnetic starter and other components of leakage protection device , For leakage and electric shock protection , It can also be equipped with buzzer 、 Signal lamp and other acousto-optic devices are combined to form a leakage alarm device . With reset 、 instructions 、 Call the police 、 Reset and other functions .
It is not suitable for the central grounding point of power supply or direct grounding system 、 Low voltage distribution system . It is a network reform product for safe use . The action time of the relay is divided into fast type and delay type , When used together, the trunk line and branch line shall be protected by classification , It can completely replace the past LLJ-□F（S）、LLJ-□H（S）、JD1 And JD3 Series leakage relay .
