Small weak motor room decoration plan
First, the ground decoration instructions
The raised floor is essential in the computer room. There are two main functions for laying the raised floor in the machine room: First, a concealed space is formed under the raised floor, and power lines, trunking, integrated wiring, fire lines, and some electrical facilities (sockets, socket boxes, etc.) can be laid under the floor; Secondly, an air-conditioned air supply static pressure box can be formed under the raised floor due to the laying of the raised floor. In addition, the antistatic function of the raised floor also guarantees the safe operation of computers and network equipment. The anti-static floor is a large part of the whole machine room. We not only consider its appearance but also consider its load-bearing ratio and whether it meets the requirements of the B-class machine room.
There are many types of raised floors. According to the board substrate and materials, it can be divided into: aluminum alloy, all steel, composite wood particle board and so on. Anti-static veneers are applied to the surface of the floor (the difference between imported and domestic). The machine room uses a full-rigid anti-static raised floor.
In addition, the flame-retardant performance and system resistivity of the full-rigid floor meet the relevant national standards, and have passed the testing of the authoritative testing department, with a nationally recognized test report.
Second, do dust and moisture treatment under the floor.
The floor is made of anti-slip paint. The anti-static floor is installed in the machine room area, UPS room and office area. The floor height is 200-300mm; the anti-static floor is treated along the wall.
Anti-static anti-slip OA floor is used at the entrance of the machine room;
When installing anti-static floor, the installation is compact and tight, no echo is generated when walking, the floor surface is kept flat, and the floor is made of wear-resistant, high-temperature resistant and good insulation performance. The space under the floor is 200-300mm.
Firstly, the laying of the floor is completed after the various types of decoration construction and fixed facilities are installed in the machine room and the floor is cleaned.
1) The building floor should meet the design requirements and should be cleaned and dried. When the raised floor space is used as a static pressure box, the walls and the ground should be treated with dust and dust, and the skin should not be peeled and cracked.
2) The floor cut on site should be smooth and burr-free, and be treated according to the technical requirements of the original product.
3) Before the movable floor is laid, the support parts are adjusted to the design height according to the elevation and the floor layout, and the floor is flat and firm.
4) Adjust the level at any time during the laying of the raised floor. In case of obstacles or irregular ground, the support components should be trimmed and attached to the actual size.
5) Take protective measures on the floor surface when handling and installing equipment on the raised floor. After the laying is completed, do an anti-static grounding.
6) Anti-static floor technical indicators
All-steel anti-static floor is made of high-quality steel plate stretch forming, spot welding, spray coating, inner cavity filled foaming cement filler, surface-bonded high temperature non-combustible grade decorative board, surrounded by conductive molding strips, brackets, shank, integral galvanized The bracket height is adjustable and can be self-locking.
Features: All-steel combination structure, high strength, strong impact resistance; high dimensional accuracy, good interchangeability; floor can be cut freely, easy to install accessories; surface electrostatic spray treatment, good corrosion resistance; fire, anti-static, anti- Dust; four sides fixed, easy to install; the lower space can be used as air conditioning ventilation; for overweight equipment, as long as the bracket is added under the floor, it can solve the bearing problem; easy to disassemble, just replace the decorative veneer, it can be reused. The all-steel anti-static elevated activity series produced by our company has PVC veneer, melamine veneer, and glass fossil veneer. Different veneers can be pasted according to different usage occasions and user requirements.
Applicable places: computer room, program control room, satellite and spacecraft reflex accusation center, monitoring command center, controller, electrified classroom, electronic reading room, dustproof, anti-static and occasions requiring overhead.
Note: 1. The floor laying height can be arbitrarily chosen.
2. The bearing capacity of the bracket is not less than 20KN and matched with the movable floor of each model.
Third, lightning protection grounding design instructions
(1) Lightning protection design
The machine room is designed with a 3-level lightning protection and integrated grounding system. The central computer room is connected to the equipotential.
(2) Grounding requirements
The grounding system must meet the following requirements:
1) Working AC grounding is not more than 1Ω
2) Safety protection grounding is not more than 1Ω
3) DC working grounding and grounding resistance should be determined according to the specific requirements of the computer system.
4) Lightning protection grounding According to the requirements in the “Lightning Protection Design Code for Buildingsâ€, the grounding resistance under joint grounding is less than 2Ω.
The purpose of the equipotential bonding is to reduce the potential difference between the metal parts and the systems in the space where lightning protection is required. Prevent lightning strikes. The metal casing, UPS and battery box metal casing, metal floor frame, metal door frame, facility piping, cable tray, aluminum alloy window and other metal and weak electrical equipment in the equipment room should be equipotentially connected and the shortest line should be used. Connected to the nearest equipotential bonding strip or to other metal objects that have been equipotentially connected, and the electrical conductors are connected as many times as possible.
In addition, considering the antistatic requirements of the equipment room, according to the design specifications of the equipment room, the electrostatic voltage of the equipment room should be <1KV. The grounding treatment must be carried out against the static movable floor to ensure the safe operation of computer equipment and personnel.
Make a circle of copper grounding net along the machine room. The specific method is to connect 30x3 copper strips. It is installed with insulated overhead. The whole machine room area forms a ring. It is connected with the grounding net by two plastic copper wires of BVR10. Floor brackets, cabinet enclosures, monitoring equipment, UPS, gas fire extinguishing equipment, etc. are grounded using BVR6 plastic copper wire to the integrated ground bus. All server equipment inside the cabinet is grounded by a plastic copper wire of the BVR4 and a cabinet.
