Power supply using a class, build uninterruptible power supply system. For external equipment, air conditioning, lighting, auxiliary sockets and other equipment provided by the engine room power distribution cabinet. Room supply and distribution system has been provided with room distribution cabinet system, voltage, frequency and the rated capacity to meet the requirements to host AC power supply, external equipment, auxiliary equipment, air conditioning, lighting and so on.
Room dedicated distribution cabinets
　　Computer room dedicated distribution cabinets, mainly refers to the low voltage distribution cabinet, power supply and distribution system in the engine room is an important component devices. Room low-voltage distribution cabinet design is correct and reasonable, power distribution cabinet member performance is good or bad, on normal use of electricity throughout the room plays an important role. Distribution cabinet by the automatic air switch, isolating switches, contactors, breakers, indicators, buttons, switches, power meter, acquisition module, power supply and other components of mine and cabinet components. Distribution cabinets specific configuration and technical requirements are as follows:
　　(1) room distribution cabinets in number, in addition to normal distribution cabinet set number, it must also increase the use of power distribution equipment. Such as: power distribution cabinets, UPS distribution cabinet.
　　(2) room distribution cabinet according to the application design and the brightest supply accurate and reliable. Different types of supply objects are not placed in a control cabinet. To retain backup circuit distribution cabinet, equipment room for expansion when available. Capacity to use and maintain.
　　(3) distribution counter board displays the current (magnitude and three equilibrium conditions) voltage and frequency with the acquisition module status to the site will be run centralized monitoring system.
　　(4) distribution cabinet electrical components should be used mainly stable quality, reliable products. They are: emergency power engine / auxiliary contacts of each switch (alarm, fault, division indication) / master switch operation mode optional / ventilation, cooling equipment / various measuring instruments / Vigil leakage protection Accessories / Release methods (heat magnetic, electromagnetic). Cable (wires, cables, neutral, ground lines, etc.) between the components according to the color of the state, symbol, number. Technical indicators meet the design requirements, to meet the requirements of computer equipment and auxiliary equipment work.
　　(5) distribution cabinet is equipped with an emergency switch. Fire alarm systems and power distribution cabinet (XP1) linkage, when the fire alarm signal is asserted by the fire control system will power distribution cabinet (XP1) the power is turned off.
　　(6) The distribution cabinet should be based on the different requirements of computer equipment and auxiliary equipment, set the neutral and ground connection device. Distribution cabinet (box) security protection ground wire (PE) should equipotential ground pool tank reliable connection, but note that the engine room power neutral (N) should be a ground line (PE) insulation.　
　　(7) Distribution cabinet adopted the bus, terminal block, and a variety of cables, wires, neutral, ground lines, in line with national standards. Off color specified by the national flag, NO. All air switch connections are made using copper.
　　(8) distribution cabinet various switches, buttons, clearly marked to prevent the use of misuse.
