LT AC and DC power supply row head cabinet (Bitcoin mining machine distribution cabinet）

Short Description:

AC and DC power header cabinet is a cabinet at the top of the equipment of a cabinet, which can provide power to the AC or DC load of the cabinet.
AC/DC power supply header cabinet is usually located at the two ends of a column of cabinet, in order to achieve the purpose of fault tolerance, mainly used in the mainframe room
The head cabinet is a cabinet at the top of a column of cabinet equipment. Usually the front end is called the head cabinet, and the end is called the tail cabinet. Its main function is to provide power to the AC or DC load of the column of cabinet, and play the functions of power distribution, monitoring, measurement, protection, alarm and so on.
The head cabinet is similar to the cabinet type distribution box, which concentrates a lot of circuit breakers.

• The power distribution circuit in the machine room is generally double-channel mains power access. The first is the mains power distribution box, part of which is fed to UPS, the other part to air conditioning, lighting and common socket. The lower end of UPS is fed to the UPS distribution cabinet, which is distributed to each header cabinet, and then connected to the PDU of each cabinet to the load.

• The header cabinet is necessary and necessary in the mainframe. First, due to the limited output branch of the UPS distribution cabinet, the header cabinet can be optimized according to the power demand of the equipment to solve the problem of insufficient branch of the power cabinet.

• Tt is convenient circuit maintenance, a single branch circuit failure does not need the main distribution cabinet power maintenance, only need to disconnect the road power maintenance, greatly improve the fault tolerance of the whole circuit in the machine room.

• Dual power supply is generally used in the power intake line of the lining cabinet. When the power supply system of the first line fails, the power supply of the other line will be automatically put in to ensure the continuity of power supply.

• General head cabinet is mainly used in communication machine room and station transmission equipment room.

Feature

• The modular structure is easy to disassemble and maintain. and the module allows users to quickly and flexibly increase and delete the circuit, so as to meet the power consumption expansion demand of the machine room.

• Distribution cabinet is usually composed of automatic control switch, isolating switch, fuse, contactor, relay, electricity meter, indicator light, button, switch and other mechanical and electrical components, semiconductor components and cabinet.

• the automatic control switch, contactor, fuse, isolation switch and other parts selected in the distribution cabinet, to reliable performance, technical indicators to meet the design requirements, can meet the requirements of the work of computer equipment and auxiliary equipment.

• there should be an emergency switch in the power distribution cabinet. When there is a serious accident or accidental fire in the computer room, it should be able to cut off the computer power supply, air conditioning power supply and new Phoenix power supply immediately.

• The computer equipment control distribution cabinet should be set up frequency table: for observation of UPS power output frequency changes.

• The power supply in each branch of the distribution cabinet set up indicator light, indicating the situation of the power supply on and off.

• The power distribution cabinet is based on the different requirements of computer equipment and auxiliary equipment, set up the connecting device of the middle line and the ground wire. The center wire is insulated from the ground wire and the shell of the distribution cabinet.

• The bus, wiring bar and all kinds of cables, conductors, neutral wires and ground wires used in power distribution cabinets shall meet the national standards.And according to the state provisions of the color mark, number.

• When the aluminum row in the power distribution cabinet is connected with the copper parts, used aluminum and copper transition materials

• The insulation performance of the distribution cabinet should meet the requirements of 20.1.1 in the national standard GBJ232-82 "Electrical Equipment Hanover Test Standard", which is generally not less than 0.5m Ω.
