Pressure reduction and energy saving method for communication power supplies

Abstract

The invention discloses a pressure reduction and energy saving method for communication power supplies and aims at providing a method to reduce float charge supply voltage of the communication power supplies. The method is used to reduce power consumptions of communication equipment. The method includes the following steps that: a storage battery pack is divided into a main storage battery pack and an auxiliary storage battery pack, wherein the storage battery pack is formed by 24 storage batteries which are connected in series; a main charger and an auxiliary charger are correspondingly parallelly connected with the main storage battery pack and the auxiliary storage battery pack; a load and a directional diode are parallelly connected with two ends of the main storage battery pack to form a float charge power supply circuit, wherein the load is connected in series with the directional diode; a normally open contact of a relay is connected between a cathode and the load of the storage battery pack so as to form a discharge circuit; a controller is used to monitor conditions of power restoration and power outage, wherein the controller is connected in the float charge power supply circuit and the discharge circuit; the controller controls a motion of the relay according to the conditions of the power restoration and the power outage. By using the invention, a requirement of load working voltage can be satisfied, charging quality of the storage batteries can be guaranteed, the power consumptions of the load during float charge power supply can be reduced. The method of the invention is an ideal method which can be used to reduce the power consumptions of the communication equipment.

Description

technical field [0001] The invention relates to an energy-saving method, in particular to a method for reducing the power consumption of communication equipment by reducing the floating charge supply voltage of a communication power supply. Background technique [0002] As we all know, my country's communication equipment adopts the DC power supply method, and its standard working voltage is -48V (the adaptable voltage range is -57V~-40V), and the standard voltage of the battery provided by the battery manufacturer is also 48V (the actual power supply voltage is 43.2V~ 55.2V); for this reason, at present, a storage battery pack formed by connecting twenty-four 2.25V storage batteries in series is used to carry out floating charging and power supply to communication equipment. However, since the floating charging voltage required by the storage battery pack is -54V, the voltage actually applied to the equipment load during the floating charging process is also -54V, which is 6...
