YJAR automatic closing overvoltage protector for lightning protection

Scope application

Automatic reclosing leakage protector is a new generation of high-tech intelligent safety electrical product that breaks through traditional safety electrical protection methods and combines mechanical automation with modern electronic control technology. This product achieves online detection function and overload (overcurrent), short circuit, overvoltage, undervoltage, and leakage protection function through microcomputer control technology. The product integrates switch and protection, realizing comprehensive protection for digital safe electricity use, and also has anti lightning surge function. Once an electrical fault is detected during use, it is immediately protected and tripped. After the fault is eliminated, it automatically recloses without human intervention, fundamentally solving the problem of power interruption due to electrical fault tripping and inability to automatically reclose.

This product is suitable for industries such as communication, transportation, industrial and mining enterprises, intelligent residential areas, petrochemicals, etc., and has a large number of successful application cases in wireless base station equipment, broadband switches, monitoring equipment, meteorological monitoring equipment, etc.

PRODUCT FUNCTION

a. Pre closing detection: The product checks the circuit before closing, and cannot close when any faults such as overvoltage, undervoltage, electricity, or overcurrent exist.

b. Overvoltage protection: Automatically disconnects when the input voltage exceeds the set value

c. Undervoltage protection: It automatically disconnects when the input voltage is less than the set value or when there is a power outage.

d. Overcurrent protection: When the current is greater than or equal to 1.15 times the rated current, the protector will automatically disconnect for 3 seconds

Open it.

e. Short circuit protection: When the current exceeds 3 times the rated current, the protector automatically disconnects within 0.1 seconds

f. Residual current protection: When the leakage current exceeds the set value or is touched by a person, the protector will automatically disconnect within 0.1 seconds

Open it.

9. Neutral wire disconnection protection: When the neutral wire is disconnected or loose, and the voltage imbalance reaches a certain value, the protector will automatically disconnect

h. Power outage protection: The protector automatically disconnects when there is a power outage, and automatically closes when the incoming call detection is normal.

i. Automatic closing: Automatically disconnect when a fault occurs; Self closing after troubleshooting.

i. Automatic saving of information: Various information about automatic disconnection, including disconnection frequency, time, fault type, etc., provides a basis for fault analysis.

k. Sound and light fault alarm: When the fault is disconnected, the corresponding fault indicator light will light up and an audible alarm will sound.
