Power supply system of communication base station

Abstract

The invention relates to a power supply system of a communication base station. The power supply system comprises a mains supply power-failure monitoring unit, a power distribution box, a standby power supply circuit, an air-cooling cycle controller and an exhaust fan, wherein the standby power supply circuit is connected with the power distribution box, a changeover switch is arranged at the power distribution box, the mains supply monitoring unit is connected with the power distribution box, a power-failure signal is sent to the power distribution box after a mains supply circuit power-failure signal is monitored by the mains supply monitoring unit, the circuit is switched to the standbypower supply circuit by the changeover switch of the power distribution box, and meanwhile,the air-cooling cycle controller is driven to control the exhaust fan to perform air-cooling circulation operation. A power supply condition of the mains supply circuit can be timely monitored by the mains supply power-failure monitoring unit, electric energy can be stably provided for a diesel generating set of the standby circuit, normal running of large-power equipment is ensured, and the risk of communication base station crashingis prevented.

Description

technical field [0001] The invention relates to the field of power supply systems, in particular to a communication base station power supply system. Background technique [0002] The main equipment in the existing communication base station, such as BTS, will generate a lot of heat when it is working. The communication base station usually cools down the main equipment through air conditioning. The communication base station also has a backup power supply - a battery pack. When the mains power fails, the main equipment can still continue to operate. After working for a period of time, the battery pack is in a floating charge state when the mains power supply is normal to ensure sufficient power. However, when the mains power fails, the battery pack cannot supply power for the air conditioner, so there is a risk that the equipment will overheat and cause the base station to be paralyzed when the battery pack alone supplies power. .
