Based on the use, the surge protector can be divided into three main categories: power lightning protection, signal lightning protection and antenna lightning protection.
Power lightning surge protector: in accordance with the principle of three-stage lightning protection, the power supply and equipment required protection measures are divided into three levels. Installation of the first level of lightning protection in the main distribution cabinet, the choice of relative current capacity of the power supply lightning protection (maximum discharge current 80KA ~ 160KA depending on the situation), and then in the subordinate areas of the distribution box at the installation of the second level of power supply lightning protection (40KA or so), and finally in the front end of the equipment to install the third level of power supply lightning protection (10KA - 40KA).
Network signal lightning protector scope of application: for 10/100MbpsSWITCH, HUB, ROUTER and other network equipment lightning and lightning electromagnetic pulse caused by induced over-voltage protection; network room network switch protection; network room server protection; network room other equipment with network interface protection; 24-port integrated lightning protection box is mainly used in the integrated network cabinet, sub-switch cabinet multi-signal lightning protection box, the main application for the integrated network cabinet, sub-switch cabinet multi-signal lightning protection box, the main application for the integrated network cabinet, sub-switch cabinet multi-signal lightning protection box, the main application for the integrated network cabinet, sub-switch cabinet, the main application for the integrated network cabinet 24-port integrated lightning protection box is mainly used in the integrated network cabinet, the centralized protection of multi-signal channels in the switch cabinet signal class surge protector.
Signal surge protector: mainly used for video signal equipment point-to-point protection, can protect a variety of video transmission equipment from the signal transmission line of the induced lightning strikes and surge voltages brought about by the hazards of the same operating voltage RF transmission is also applicable. Integrated multi-port video lightning protection box is mainly used in the integrated control cabinet within the hard disk recorder, video cutter and other control equipment centralized protection.
obo surge protector how to choose
1, the total distribution cabinet to install the first level of surge protector, T1 test products, you can choose AM-10/350 (25KA4P) to meet the requirements of the national standard.
2, sub-distribution cabinets installed T2 level surge protector, 40kA, you can choose AM40A.
3, the last level of lightning protection selection AM20C275, Up: 1.2kV. If over the national standard acceptance of the project, according to the above with no problem. However, the surge protector selection is not set in stone, many times according to different circumstances will be adjusted.
Summary
obo surge protector role we also understand it, some knowledge about electricity, or more understanding of some of the better, some of the switches, protectors, these with the wrong, the danger is very easy to happen, and the installation of the time to disconnect the power to the pen, the multimeter these are ready Oh. About obo surge protector types and selection methods, I told you here, if you want to know more about this knowledge, you can pay attention to the Rilong decoration network, which will have more about the decoration of more professional answers waiting for you!
