Description

An integrated power distribution system

Technical field

The present invention relates to the technical field of power distribution equipment, and more specifically, to an integrated power distribution system.

Background technique

In recent years, my country’s software and information technology industries have developed rapidly. With the strong support of national policies, customers in the financial, telecommunications, manufacturing, energy, transportation, government and other industries have continuously built and upgraded data centers to improve their business operations. Carrying capacity, improve the efficiency of operation and management. my country's data center IT market has maintained a continuous and rapid growth trend. With the large-scale construction of data center computer rooms, technology continues to introduce new technologies. Not only does the computer room need to be maintained and repaired from time to time, but the computer room needs to be expanded according to business growth, and the power distribution system that carries the data center business needs is becoming more and more complex.

Before 2010, the power distribution of the cabinets in the domestic data center computer room used the head cabinets for power distribution. The head cabinets of the data center originated from the power distribution cabinets usually placed at the end of a row of IT cabinets. As a terminal power distribution cabinet for power distribution and protection of one or several rows of IT cabinets, the head cabinet usually receives power from the front-end UPS cabinet with a main circuit breaker, and then relies on multiple miniature output circuit breakers to radially interact with the PDUs of each IT cabinet Connect to form the traditional terminal power supply and distribution system of the data center. The main problem with the current data center power supply method is the large number of cables, not only the relatively high power loss, but the unattractive environment, and it is difficult to maintain and expand the capacity later.

In the past five years, with the rapid development of data center construction and higher demand, the data center intelligent small bus system has gradually been applied to the terminal power distribution of the computer room. This small bus system is equivalent to a customized and special-shaped small bus system. Frame beams are required outside the bus bars, and bus ducts are provided in the frame beams; its biggest advantage is plug-and-play and flexible installation positions, but due to the high price, the application occasions are more limited. A small bus system based on the traditional ordinary low-voltage bus is derived from this. This type of small bus system adopts a fixed output mode. The output port is the socket part of the industrial connector, and the wiring of the socket part of the industrial connector is directly connected to the small bus. On the bus main bar, each industrial connector socket corresponds to a cabinet position. It has the advantages of low current and lower price than the plug-and-play smart bus; but the problems with this solution are: 1. Its Limited by the structural form of the industrial connector socket part being fixedly installed on the small bus bar, the space is small and the power monitoring device cannot be installed, which makes it impossible to realize intelligent power monitoring; 2. When a short circuit occurs in the lower-level separate cabinet, It will affect the power supply of the small bus system of the entire group; 3. When the small bus is working, the plug-in interface is live, and online maintenance and repair cannot be performed; 4. The output loops are relatively scattered, which is not conducive to centralized maintenance.

In view of this, it is necessary to provide a new technical solution to solve the above-mentioned problems.
