LH series power lightning protection box is mainly used for weather, transportation, post and telecommunications, computer  network, power distribution box, residential,  railway and other  fields.Power supply prevents thunder B,C,D, are the three levels, according to the IEC (international electrotechnical commission) partition of  lightning protection, multi-level protection  theory, class B  belongs  to the first  level  of lightning  protection  lightning  protection device, can be applied to building the ark of the main distribution:class C belongs to the second level of lightning protection lightning protection device, applied  to the structure of the shunt power distribution cabinet; D belongs to the third  level of  lightning protection  lightning protection device,LH lightning protection box effectively restrain the road from the ac power supply cord into the induction lightning waves, and electrostatic damage to protect electrical equipment from lightning strike.

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 strikesWe take “customer-friendly, quality-oriented, integrative, innovative” as objectives. “Truth and honesty” is our management ideal for China Wholesale China Hmp1500V-S Solar Photovoltaic DC Junction Box for Utility-Scale Photovoltaic Systems, And we are able to enable on the lookout for any products with the customers’ needs. Make sure deliver the best Assistance, the most beneficial High-quality, The quickly Delivery.

●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.
