Discussion on common problems and solutions in computer room

first, the engine room catches fire

Machine room due to the density of more than the cabinet, air conditioning cooling power is not enough, can lead to the room heating, in order to better solve this problem, we need to consider the reasonable placement of the cabinet, reasonable configuration of precision air-conditioning.

Every room of the power distribution is crucial, the treatment is not good will become the source of the spark, we all know that the distribution cabinets should be in a radial and trunk-type combination of methods, the use of centralized distribution and decentralized distribution (in-depth load zone) combination. The distribution cabinets will be designed according to actual power consumption and expandable capacity.

The distribution cabinet is equipped with Overvoltage, overcurrent, undervoltage, missing equal alarm protection indication

cable laying, piping wiring should pay attention to:

All the cables and plastic copper wires are laid in a steel wire groove, the branches are lined with wire pipes, and the ends are made of metal hoses. All the slots are raised 3 centimeters above the ground to prevent water hazards.

Wire pipe, metal wire groove are reliable grounding.

The functional area from the UPS output cabinet to the terminal cabinet all the wire selection of flame-retardant power cable rvv3*4 Square cable 16A socket using GB products. All remaining wires are made of flame-retardant plastic copper wire.

All cables are required to meet the equipment power requirements and are equipped with flame retardant cables.

No more load per power outlet

Be sure to separate the ground and 0 lines of the computer

Consider the maximum current that can be passed by the power transmission line

second, the computer room cabling

Room in the long-term construction process, if can not standardize the layout, will lead to the computer room network cable, power lines such as spider web Cave-like very chaotic, in the early layout of the machine room we need to take into account the problem of the computer room cabling, to take into account the strength and weakness of the electric separation line, to avoid interference between strong and weak electricity Reasonable layout will also make the machine room wiring looks orderly.

third, the engine room load

The calculation of load-bearing problems is not the weight of the cabinet/enclosure area, which is the wrong algorithm. In fact, the real floor area of the battery cabinet may be the area of 4 screws, the static pressure on the ground is very large, usually dozens of k kg squared.

If according to this algorithm, each adult assumes 70kg, a pair of feet together when his foot to occupy the ground 30cm long x10cm wide x2=0.06 square meters, that his static pressure is 1166kg/square meters, far more than 500kg, is not we people can not stand in the room, can only crawl into, Rolled out.

This is the difference between static pressure and load: Static pressure is the actual weight/actual floor area (may be a few screw area), very large, usually hard ground (cement steel plate, etc.) can be put, design products are calculated. The load is an average concept for calculating the deflection of beams and columns, etc.

In actual engineering calculation, the following considerations can be considered:

1) The total weight of the room can not exceed the total area of the computer room x load 80%. For example, a site area of about 50 square, according to the lowest 200kg/square meters, then all equipment can not be more than 8000kg

2) The equipment of the room is arranged as evenly as possible

3) Heavier equipment, near the beam of the cloth or near the column.

4) partition calculation This room is divided into 3 rows of cabinets, ups and battery distribution cabinets and maintenance area accounted for 1/3, the total amount of this row control in 8000/3= 2666Kg can be
