2021-03-23
Shielded cabinet is a kind of cabinet, ensure that the inside of the cabinet equipment is not affected by the interference of external environment and equipment, and invasion, ensure that these institutions and departments of information security.
For the modern computer information safety, is an important and indispensable protective measures.
What are shielded cabinet note?
installation and debugging matters needing attention
using the environment: the environment temperature - 25 ℃ + 70 ℃ relative humidity > 85% to prevent contact with corrosive substances and the gas phase.
equipment to determine its location and position, flat, dispatch four positioning bolt, prevent rack shift when using.
shielded cabinet should be reliable grounding, grounding resistance should be 1 or less Ω, grounding piles and shielded cabinet leading-out terminal bolt grounding resistance should be 0 or less. 1Ω。
must be ground prior to power; Grounded outlet before there can be no leakage protector, such as the building electrical system, leakage protector, the leakage protector should be early to pull all the way alone the power to the cabinet power supply. Is due to the filter capacitor inductor, capacitor has the effect that inflation, or in front of the socket and isolation transformer or special power socket; Is not grounded shielding ark of resistance should be greater than 1000 Ω.
installed into the cabinet to pass shielding fiber line and shielding copper tank at the back of the guide hole, at the same time on the response of the cable shielding mesh and metal wire should be cut off from within the screen before the ark, and outside two aspects, the truncation of the screen mesh and wire is fixed on both ends of waveguide metal gong's mouth. Make it through the shielded cabinet good grounding. Shielding effect.
the number of waveguide shielded cabinet should be according to the actual needs of customers custom installation in production. A cable into the shielded cabinet needs a waveguide, and need to distinguish between optical fiber and shielding copper.
shielded cabinet is suitable for the large network, communication and computer room servers, switches, routers and other network equipment of electromagnetic protection.
