What measures should be taken to mine computer room?
(1) In the building where the central engine room is located, an independent lightning rod network shall be installed to protect the entire building where the central engine room is located, and currents shall be introduced into the ground. Now, some architects use the steel bars of the building itself as lightning current off-line. This is also a reasonable method for computer rooms with fewer computer communication devices. All metal pipes, enclosures, switch cabinets, and central circuit devices that enter the central computer room should be integrated into a unified electrical system and connected to a dedicated unified network. The arrester should be installed on the telephone line of the core box of the computer communication cable.
(2) The lightning protection of the telephone network, because a large number of integrated circuits in the program-controlled switches used by them have insufficient resistance to over-voltage over-current, and lightning arresters should be installed on the poles for overhead lines. Install the protector at the road end. Once the line is struck by a lightning strike, discharge through the discharger. In a short time, the large current will not burn the fuse, so as to ensure the smooth communication. Once the lightning strike current is too large, the fuse is blown to ensure the safety of equipment personnel. In general, the regions where the thunderstorms occur frequently should be slightly thicker in the area, and the thunderstorms should be reduced in some areas. If thin bare copper wire is used, the thickness should not exceed 0.48mm, and the fineness should be 0.39mm.
(3) Lightning protection for the power entry line is generally installed on both sides of the distribution transformer. Grounding is performed on the last few poles of the low-voltage long-line feeder to allow the lightning to be shunted and attenuated to prevent lightning from entering the power line.
Local network lightning protection measures such as Novell and Ethernet generally do not pass Modem. If the signal line is not long, it is relatively safe to ground and put on the metal pipe. If the signal line is long, lightning arresters using zinc oxide materials should not be considered because of large signal loss, but they can be used in remote telephone networking.
(4) Lightning protection of cables. Even cables buried in the ground may be struck by lightning, and some may not cause insulation breakdown at that time. Even if the insulation is broken down, it will not necessarily result in immediate interruption of communication. Intermittently.
(5) The most fundamental one when lightning protection is grounded. However, if it is grounded but not qualified, it will create conditions for lightning strikes; similarly, qualified at that time does not mean always qualified, annual inspection before the thunderstorm season is indispensable, many computer rooms in the education system of a city in Jilin Province directly to the ground The danger is in front of the heater pipe, and the staff thinks it is safe. This is worth reviewing.
