Construction of lightning arrester in security project
The lightning arrester is to protect all kinds of equipment from the impact of thunder and lightning, and it will often be used in security construction. In order to ensure normal operation, we must do three aspects of construction, so as to ensure safety and prevent accidents.
Arrester construction:
Arrester on-line monitor company first introduced for power system security protection project, need to set up three levels of protection, a protected SPD installed in the general power distribution box, two lightning protection SPD installed in the distribution box room, three door SPD installed in the supply room equipment. In general, the first and two levels of the power supply system have been set up, so long as the three level protection is done in the construction process. Through the three level protection of the power supply system, the lightning current is fully resisted to the power line to enter the machine room and prevent the equipment from being struck by lightning.
Second, outdoor equipment to do direct lightning and lightning protection work. There are more general in the construction of lightning protection is installed in the outdoor camera, you need to install a small lightning rod on the support rod for camera power supply, control line, video line were installed on the lightning protection device, or the three in a lightning protection device, the three signal for the comprehensive protection of all kinds of lightning protection and grounding the device is connected to the internet.
Finally, lightning arrester on-line monitor, the whole system in accordance with the equipotential principle, work, protection, shielding, building lightningproof grounding equipotential connection and grounding, to prevent the lightning overvoltage caused by ground potential rise caused by.
