Design and construction of power supply wiring in Internet bar wiring

Internet cafes currently provide services, such as Web browsing, network games, online movies, distance education and other basic services are related to the network, the quality of the network directly determines the viability of Internet cafes. Therefore, how to plan a high-quality network environment, is an Internet café operators must consider a key point, the integrated wiring of Internet cafes accounted for a large number of factors, mainly two major parts: power wiring and network wiring.

Wiring of the power supply system
Internet café power system wiring, can be divided into design, construction, acceptance of three steps, in these three steps need to pay attention to the following rules and matters.

First, wiring design
Now the mains supply system is commonly used three-phase four-wire power supply mode, it is recommended that the two-phase power supply is still used to replace the three-phase four-wire power supply mode. For ordinary internet cafes, the main electric net bar system is:

1, Air conditioning: For Internet cafes, air-conditioning has become a standard configuration, the general use of cabinet-style air-conditioning, and power consumption is very large, each power generally between the 3500-4500w. Therefore, in the design of the power wiring system, the air-conditioning must be equipped with dedicated power lines.

2, the computer: generally in the Internet café power system wiring design, easy to create a misunderstanding, that the use of the computer power cord just pull one on the line. In fact, the total load in the Internet Café is the largest computer, in the case of not equipped with speakers, power generally around 150W, the number of machines increased, the power is significantly increased. Therefore, the Internet Café computer use of the power cord, should not be a series of mode, but the use of grouped points, the specific practices are as follows:---http://bianceng.cn (learn computer)

Every 1.5 meters or so access to a 10A three-core GB socket (that is, the wall embedded independent sockets) as a point, the above porous socket will be connected to the 1.5-meter range, and 4-5 computers will use this socket to connect to the power supply; Then, visual reality of the computer by 10 or 16 for a group, each group by an air switch control, the entire Internet café Can be grouped into 4-6 groups or more.

According to the load of each trunk, reasonable choice of power cord model. In general, the backbone of the use of copper core lines, the following branch lines can be used aluminum core line (I suggest that the best Internet cafes power system all the lines of the GB copper core line). At the same time, according to the load of power reasonable choice of different specifications of the power cord.

3, network equipment and lighting equipment: for a professional cabinet of Internet cafes, the proposed router and other High-value network equipment plus UPS back-up power to protect network equipment security.

Second, the concrete construction
1, the power wiring should be synchronized with the room decoration, in order to the beauty of the Internet café environment, should not be the power line layout in Housetops, can be placed in the PVC pipe or dedicated power line channel.

2, for the more important trunk lines, preferably in the wiring construction more than laying a line to do backup lines. At the same time, in order to avoid affecting the transmission quality of network cable and telephone line, the power cable is best to go alone a pipe or PVC trough. For some pipe that is not easy to carry out two times, make sure to lay the standby line.

3, the choice of power supply backbone and branch line specifications, the proposed in the current load power on the basis of floating 50-80% value to meet the future upgrade of the Internet Café machine power demand.

4, when laying the power cord, you should do some marking. Each air switch controls which line, must make the detailed record.

Third, acceptance
After all power wiring work is completed, a series of acceptance and inspection must be performed before all wiring pipelines are closed. Power system detection, mainly divided into the following areas:

1, testing all equipment work is normal: the Internet café power wiring After the work, please test all the lines are able to work properly, the air switch work is normal.

2, the full load operation of the Internet bar: After the first Test run, the equipment in the Internet café in batches to open, and gradually reached the full load of the Internet café power operation. It is best to run the whole load at more than 24 hours, in order to verify the true performance of the power wiring system. In the full load operation process, if the air switch automatically tripping or fuse is burned, please be sure to carefully check the reason.

3, Internet cafes overload operation: After full load operation, can carry out a short period of overload operation to detect the power system quality and compressive performance. The overload operation time can be in 10 hours, according to the actual situation carries on the test.

Iv. several issues to be noted
The whole process of power wiring of Internet bar, we must attach great importance to some small problems, some minor mistakes can cause incalculable loss.

1, the grounding of the installation: careful technical staff will find that the three-phase power plug in the computer, is responsible for the grounding of the core, there is no power cord, that is, the lack of effective grounding measures. However, the Internet café inside the computer and some network equipment, in the normal work of the shell may produce some static electricity, if there is no effective grounding measures, static accumulation to a certain extent, may burn hardware or injured people. Therefore, in the Internet café power wiring, must be installed ground.

2, lightning protection measures: in the eyes of many technical personnel, lightning seems to be irrelevant with internet cafes, but, if the Internet café does not have good lightning protection measures, when the lightning, it may burn all the equipment in the Internet café.

3, Backup lines: For the Internet bar power system backbone lines or some inconvenient repair lines, must lay back lines, if the main line is damaged, immediately replace the backup line. Especially for the Internet cafes in business, cloth equipment part of the line is to improve the competitiveness of the Internet cafes a major initiative.

4, high-quality wiring between: For hundreds of internet cafes, in the design of the power system is best to prepare an independent space to install air switches, UPS and other Internet bar power equipment.

5, in the use of three-phase four-wire system of Internet cafes, design power systems, to ensure that three of the line of fire load do not vary too much, the difference is about 500W best.

Internet bar power system wiring, it is best to find a professional electrician or professional integrated wiring personnel to do, and to do a good job wiring the file records, each power cord is responsible for the scope, direction, etc. to be recorded in the document in order to facilitate future maintenance.
