One end of the power lightning arrester connection is directly and firmly connected to the terminal of the lightning arrester. The grounding wire is connected to the independent grounding network or to the ground wire in the three-phase power supply provided by the school.
The power line lightning arrester is red, the neutral line is blue, the cross-sectional area is BVR6mm2 multi-strand copper wire, the ground line is yellow-green color, the cross-sectional area is BVR10mm2 stranded copper wire, the wiring length is less than or equal to 500mm. The standard of ≤500mm can be appropriately extended, but the principle of short wiring should be followed. The reasonable arrangement and installation of the power supply when installing the lightning arrester can be used in the industry, and the service life and age limit of the use can be appropriately extended.
The corner should be greater than 90 degrees (it is an arc angle instead of a right angle).
Power surge arrester installation precautions:
When installing the power surge arrester, you should first connect the ground system securely before connecting other lines.
When the working status indicator glows green, it indicates that the lightning protector is working properly. When it glows red, it means that the lightning protector has damaged the device and the lightning protection effect has deteriorated. It must be replaced immediately.
When installing, it must be disconnected from the power supply. It is forbidden to operate with electricity. The connecting wires must meet the requirements.
The lightning protector does not need special maintenance, just periodically check whether the connection is loose and the working status indicator is normal.
There are many issues that need attention in the installation of power surge arresters, and they must be installed and used according to certain methods and principles to ensure that they have important functions and values ​​in the insulation equipment.
Power surge arrester basic knowledge and installation precautions
The power surge arrester is a new type of lightning arrester that can be used to play an important role. It is used and installed according to a certain method and principle during installation, and it is used and installed according to a certain amount of configuration to promote the full use of the maximum functions and functions. The power surge arrester is installed in parallel, and the installation position is the rear end of the switchboard or switch (circuit breaker) in the satellite teaching reception classroom, and is fixed on the wall with four sets of M8 plastic expansion and matching self-tapping screws. Dimensions (70 x 180) and the corresponding mounting holes on the arrester of the power supply are used to drill on the wall. When installing the lightning arrester, the correct method and method can be ensured, and it can be constantly developed and exquisite, prompting good use.
