Precautions for the use of power lightning arrester include the following aspects:
Proper grounding: The lightning protection power supply must be properly grounded to ensure that it effectively guides and disperses the energy of lightning or overvoltage. The grounding wire should be connected to a reliable grounding system and comply with relevant safety standards and specifications.
Installation location selection: The lightning protection power supply should be installed as close to the equipment as possible to shorten the length of the power supply line and reduce potential interference. The installation location should be away from environments such as moisture, corrosive gases and high temperatures to ensure reliable operation of the equipment.
Reasonable wiring: When connecting the lightning protection power supply and the equipment, appropriate power cables and plugs and sockets should be used, and the power cord should not be parallel to other signal lines or interference source lines to reduce interference and crosstalk.
Regular inspection: Regularly check the working status and grounding of the lightning protection power supply, including observing the indicator light status, measuring the output voltage and current, checking the connectivity of the grounding wire, etc., to ensure its normal operation and timely detection of potential problems.
Disconnect the power supply before installation: When installing the power supply lightning arrester, the power supply must be disconnected before installation to avoid accidents.
Requirements for connecting wires: The minimum cross-sectional area of the connecting wires of the lightning arrester should comply with the relevant provisions of the national lightning protection project. Usually, multi-strand copper wires of not less than 6mm² are used, and they are required to be short, thick and straight.
Indicator light status check: During the use of the lightning protection box, the indicator light working status should be regularly checked and checked. The green indicator light indicates normal operation, and the red indicator light indicates a fault, which should be repaired or replaced in time.
