Abstract

The embodiment of the invention discloses an anti-reverse connection protection circuit and communication power supply equipment, which are used to avoid equipment damage caused by the reverse connection of the positive pole and the negative pole of the battery pack. The anti-reverse connection protection circuit is connected between the rectification module of the power supply system and the battery pack, and includes: a control switch, a detection circuit and a control circuit; wherein the control switch is connected between the negative pole of the rectification module and the battery switch The connection line between the output terminals of the power supply system; the detection circuit is connected between the positive pole of the power supply system and the input terminal of the battery switch or is connected between the positive pole of the power supply system and the output terminal of the battery switch between the positive pole and the negative pole of the battery pack are detected to disconnect the control circuit; the control circuit is connected between the positive pole of the power supply system and the negative pole of the rectifier module, It is used for controlling to turn off the control switch when the control circuit is disconnected.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an anti-reverse connection protection circuit and communication power supply equipment. Background technique [0002] Communication power supply equipment is the heart of the communication system, stable and reliable communication power supply equipment is the key to ensure the safe and reliable operation of the communication system. Once the power supply of the communication power supply equipment is interrupted, the communication system will not be able to operate, which will cause great losses. Therefore, the current communication power supply equipment is generally an uninterruptible power supply equipment, and the communication power supply equipment includes not only a rectifier module, but also a storage battery pack. [0003] In the prior art, the positive and negative poles of the rectifier module are directly connected to the positive and negative poles of the ...
