Abstract

The invention provides a method and a device for supplying power to chassis equipment of a communication machine room. In the method for supplying power, an output end of a standby UPS is connected in series with an input end of a primary UPS bypass; a primary UPS is used as a power supply of single power supply equipment in a chassis and used as one path of power supply of dual power supply equipment in the chassis at the same time; and the standby UPS is used as the other path of power supply of the dual power supply equipment in the chassis. The invention also provides the corresponding device for supplying power. The method and the device are suitable for service power distribution of the chassis with the single power supply equipment and the dual power supply equipment, the primary UPS and the standby UPS are adopted to share load, the reliability of power supply is improved and the load power supply is not required to be switched regularly.

Description

technical field [0001] The invention relates to the field of communication energy equipment UPS products, in particular to an AC uninterrupted power supply method for rack equipment in a communication machine room and a corresponding power supply device. Background technique [0002] With the rapid development of communication technology, UPS power supply system has become an essential power supply in the communication industry. The reliability of the UPS power supply system is the basic prerequisite for the availability of communication equipment. Under normal circumstances, users think that the use of UPS redundant parallel system can ensure the safety of power supply. However, most UPS models with low and medium power do not support parallel redundant function. , How to improve the reliability of UPS power supply is a major focus. The following two UPS power supply schemes are widely used in the prior art. [0003] The first power supply scheme is UPS series hot backup...
