How to use lightning protection and grounding for outdoor security monitoring items?
We know that the security monitoring outdoor installation is important, is the lightning protection, as building security monitoring system of embedded system, the monitoring of lightning protection mainly from the lightning-proof electromagnetism pulse and lightning-proof is invaded, considering for installation in the front-end equipment such as outdoor camera, also direct lightning protection measures should be taken.
1 ,front-end equipment such as camera should be placed in the flash (lightning rod or other flash conductor) within the effective protection range.In the case of independent camera installation, the lightning rod should be 3-4 meters away from the camera.If it is difficult to install the lightning rod, it can also be installed on the camera support, and the lead can be directly used with the metal rod itself or with φ 8 galvanized round steel.To prevent electromagnetic induction, the power cable and the signal cable of the camera along the rod lead must be shielded through a metal tube.
2 , In order to prevent the lightning wave from invading the front-end equipment along the line, appropriate arrester should be installed on each line in front of the equipment, such as power cable (AC220 volt or DC12 volt), network cable, control line and switch line.
3 ,The power supply of the camera is usually AC220 volt or DC12 volt.If the camera is powered by a DC transformer, the single-phase power arrester should be connected in series or parallel to the front of the DC transformer.If the DC power transmission distance is greater than 15 meters, the camera end should also be connected in series with low-voltage DC arresters.
4 , the outdoor front-end equipment should be well connected to the ground, the ground resistance is less than 4 ω, high soil resistivity area can be relaxed to <10 Ω.
Outdoor monitoring lightning protection is necessary. You need to know the installation and construction technology of the lightning protection equipment in detail.Lightning protection equipment is very important to the security monitoring equipment.Installation is required for all outdoor weak current projects.As a weak current construction personnel, the installation of all weak current engineering equipment should have lightning awareness.
