The Precision intelligent column distribution cabinet is the Precision intelligent column distribution cabinet of a row of cabinet equipment. Usually the one at the front is called the head cabinet, and the one at the end is called the tail cabinet. Its main function is to provide power for the AC or direct load of this row of cabinets, and to perform functions such as power distribution, monitoring, measurement, protection, and alarming. The Precision intelligent column distribution cabinet is similar to a cabinet-type distribution box, and many circuit breakers are concentrated in it. Next, we will introduce the main functions and usage principles of the cabinets.
The power distribution column cabinet is referred to as the Precision intelligent column distribution cabinet for short, and the Precision intelligent column distribution cabinet is divided into ordinary Precision intelligent column distribution cabinet and precision Precision intelligent column distribution cabinet. Ordinary head cabinets are mainly used in communication equipment rooms and station transmission equipment equipment rooms. They are installed at the head and tail of the equipment, and are matched with bar-shaped communication equipment columns and optical terminal equipment columns. Through the power distribution device in this equipment, it serves as a Perform power distribution.
The precision column head cabinet is a vital part of the computer room power distribution in the entire computer room, but it is also a level that is easily overlooked. The current computer room equipment servers, air conditioners, UPS, fans, etc. have been able to monitor at any time This step, and the monitoring of power distribution in the computer room is just a blank. The traditional power distribution cabinet is just a few meters plus a few required switches. Second transformation (adding various modules). This is both cumbersome and ineffective.
The power distribution circuit in the computer room is generally connected by two-way mains power. First, it enters the mains power distribution box, one part is for UPS, the other part is for air conditioners and lighting, and ordinary sockets. Connect to the PDU of each cabinet after the head cabinet and then to the load.
The power supply line of the head cabinet generally adopts dual power supply lines. When one power supply system fails and the power is cut off, the other power supply is automatically switched on to ensure the continuity of power supply. In order to realize short-circuit and overload protection, a molded case circuit breaker is used in front of the dual power supply to provide short-circuit and overload protection, and also has an isolation function for easy maintenance. The electrical fire monitoring system, electrical fire detector and monitoring unit are generally required to be installed in the box. Since the equipment in the computer room is very sensitive to lightning strikes, it is generally necessary to choose a surge protector.
Molded case circuit breakers can be selected for the main outgoing circuit of the Precision intelligent column distribution cabinet, and leakage modules can be installed if necessary. The power supply continuity of the equipment in the computer room is very important. The power parameter measuring instrument is equipped at the incoming line of the head cabinet, which can monitor the level of electrical parameters in real time, send fault alarm signals in time, detect potential hidden troubles in advance, and monitor the power consumption level at the same time.
The power distribution module can be selected as required in the Precision intelligent column distribution cabinet. The modular structure is convenient for disassembly and maintenance. The module allows users to quickly and flexibly add and delete circuits to meet the expansion needs of the power consumption of the computer room.
