The Precision intelligent column distribution cabinet literally means a cabinet at the end of a row of cabinets. In fact, the head cabinet is just a more vivid definition of equipment management and distribution cabinets. Its placement is often at one end of a row of cabinets, but in fact it can be located at any position in a row of cabinets, or even placed alone.
There are generally two types of Precision intelligent column distribution cabinets: strong current cabinets and weak current cabinets. The strong current cabinet is a device for managing and distributing mains power or UPS power, and is often located at the end of a row of cabinets. For the computer room with fault-tolerant requirements, the high-power row head cabinets are usually located at the two ends of a row of cabinets to achieve the purpose of fault tolerance (n+n). Weak current column cabinets are mainly used for distribution of cables in network wiring.
There are too many weak current cables in the computer room, and it is possible for a small computer room to manage all the network cables through one or two main distribution frames. In medium and large computer rooms, it is unimaginable if they are all concentrated on the main distribution frame, so it is necessary to add 1~2 level cabinets to disperse the cable layout. In a general computer room, the strong current column cabinets are located at one end of the cabinet, and the weak current column cabinets are located at the other end;
for computer rooms with fault tolerance requirements, it is more common to have strong current column cabinets at both ends, and weak current column cabinets at one row. middle of the cabinet.
The management function of the strong current column cabinet is very strong, and now there are precision column cabinets that strengthen the management function of the strong current column cabinet.
It can not only monitor the conventional electrical parameters and switch status, but also detect the zero line current , Dynamic adjustment of three-phase imbalance and other issues.
The weak current Precision intelligent column distribution cabinet is more inclined to distribution, but after adding the electronic wiring system, the management function of the weak current Precision intelligent column distribution cabinet has also been greatly strengthened.
The difference between the head cabinet and the power distribution cabinet:
1. Current monitoring is different:
The head cabinet monitors the total current, the current of each branch of the three-phase power and the current of each output branch to the cabinet. The power distribution cabinet only monitors the total current.
2. The circuit structure is different:
The head cabinet makes the computer room form a two-layer circuit structure, forms a tree-like electricity consumption monitoring and management, adjusts the operation mode, and optimizes the electricity consumption structure. The circuit in the computer room of the power distribution cabinet has only one layer of structure, and the display of current distribution is not clear
3. Different monitoring electric energy:
The Precision intelligent column distribution cabinet is equipped with a power module to measure and calculate the power consumption, so as to achieve reasonable and economical power consumption and reduce power consumption costs. The power distribution cabinet has no power consumption display, and cannot provide power consumption data for the equipment room.
4. Different equipment integration:
The head cabinet is highly integrated, and the volume is reduced under the same capacity. The power distribution cabinet is large in size and occupies space in the equipment room.
5. Different connection methods:
The Precision intelligent column distribution cabinet adopts hot-swappable connection, which is easy to install and operate. The power distribution cabinet adopts terminal hard link, which requires professional electrician to operate.
