One 、 Product overview

Leak detection relay JY82-2P

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 .

Rated current of the product 、 Leakage current 、 Transformer aperture . Rated voltage and working voltage . If delay is required , You have to specify the time .

1. Expand the scope of control : for example , When the control signal of multi contact relay reaches a certain value , It can be in different forms of contact groups , Simultaneous connection 、 Disconnect 、 Turn on the multiplex circuit .

2. Zoom in : for example , Sensitive relay 、 Intermediate relay, etc , With a very small amount of control , A circuit that can control a large amount of power .

3. Integrated signal : for example , When multiple control signals are input to the multi winding relay in the specified form , After comparison and synthesis , Achieve the predetermined control effect .

4. Automatically 、 remote control 、 monitoring : for example , The relay on the automatic device works with other electrical appliances , It can form a program control circuit , So as to realize automatic operation .
