Structure and Principle

Lightning protection box in parallel to the protected equipment front-end, under the condition of normal operating voltage, power supply lightning protection box in a high impedance state, does not affect the normal work of the circuit. When there is pulse surge line lightning strike, power lightning protection box in the nanosecond time conduction, quickly put the overvoltage of diarrhea in the earth, when the pulse over-voltage  disappears, power lightning protection box and automatic recovery to a high resistance state, does not affect the line power supply. With module alarm indicator, provide module deterioration indication 4With power status indicator lamp to indicate the working status of lightning arrester , Equipped with lightning counter to accurately record the number of lightning strikes

  • ●The power must be cut off before installation, and live operation is strictly prohibited
    ●The lightning protection box can be hung on the wall or placed horizontally.
    ●When installing, please connect according to the installation diagram. Among them, L, L2, L3 are phase wires, N is the neutral wire, and PE is the ground wire. Do not connect it wrongly. After the installation is complete, close the automatic circuit breaker (fuse) switch and check whether the working state is normal
    ●During the use of the lightning protection box, you should regularly check and check the working status of the indicator: the indicator light is green, indicating that the power supply and lightning protection of the lightning protection box are normal; bright red indicates that the lightning protection box has deteriorated and should be repaired or replaced in time.
    ●The lightning protection box equipped with lightning counter has a counting range of 0-9, and the minimum operating current is 1kA. Press the “reading” button, and the window will display the number of lightning strikes. If you do not operate for 20 seconds, the counter will automatically enter the sleep state.
    ●The connecting wire should be a multi-strand copper wire not less than the standard requirement, and it should be short, thick and straight.
