Testing method of low-voltage power supply and distribution system of data center

Abstract

The invention discloses a testing method of a low-voltage power supply and distribution system of a data center, which adopts the working state of a low-power stand type heat load simulating server which can be installed in a cabinet, uses the low-voltage power supply and distribution system of the data center as an organic whole, and simultaneously tests equipment, a centralized monitoring system and an air-conditioning system in the low-voltage power supply and distribution system with loads. Before the data center is used, by comprehensively and systematically testing the power supply and distribution system in an on-line way, the invention can find out hidden faults and hidden hazards and can decrease the risk of power failure to the minimum. The invention not only can effectively debug the power supply and distribution system, the air-conditioning system and the centralized monitoring system integrally, but also can simultaneously test three systems, thereby shortening the testing period and improving the working efficiency.

Description

technical field [0001] The invention relates to a method for testing a low-voltage power supply and distribution system of a data center. Background technique [0002] The data center (Internet Data Center) is a place where data resources are concentrated, integrated, shared, and analyzed, and it is an enterprise's business system. It can be divided into main engine room, auxiliary area, office area, etc. according to its functions. Its infrastructure mainly includes: power supply and distribution system, air conditioning and ventilation system, lightning protection and grounding system, fire alarm and automatic fire extinguishing system, weak current system and IT equipment Wait. [0003] The power consumption of the data center belongs to the first-level load, and it is not allowed to cut off the power, especially in high-density computer rooms, once the power is cut off, it will cause heavy losses. Therefore, as the most important part of the data center, the power supp...

AI Technical Summary

Problems solved by technology

The capacity of the resistance box is generally tens to hundreds of kilowatts, and it can only be connected to the UPS output power distribution cabinet, but not to the PDU (plug board) of each cabinet, so that it is impossible to test the UPS output power distribution cabinet. All the power distribution systems between the PDUs in the cabinet, and the heating points of the resistance box are very concentrated, and it cannot be placed in the computer room to simulate the server to test the cooling capacity of the air conditioner and the air distribution in the computer room
