UPS dual-channel power supply automatic maintenance control device

Abstract

The invention relates to a UPS duplicate supply automatic maintenance control device, wherein, the input end of the UPS is respectively connected with a circuit A and a circuit B of the commercial power, belonging to different phases; a discharge relay is connected with the circuit A through a time control switch, a circuit A relay is connected into the circuit A through a normal opening contact of a guide relay; the normal close contacts of the circuit A relay are connected in series and then connected with the input end of the circuit B, a circuit B relay is connected between the series connected points; the circuit A is connected with the input end of the UPS after the circuit B relay is connected with the normal close contacts of the discharge relay in series; a direct relay is connected with the output end of the UPS, the output end of the UPS is used as the output end of the whole power supply through the normal opening contacts of the direct relay, the circuit B is connected with the output end of the whole power supply through the normal closing contacts of the direct relay. The input end of the UPS and the output end of the whole power supply are respectively connected with a lightning proof circuit and a wave proof circuit. The UPS duplicate supply automatic maintenance control device is applicable to medical equipment, medium and small web server, etc. which need the UPS to supply power, achieves duplicate supply, more ensures the power supply, avoids the interference factors such as lightning, wave and others, and the storage battery of the UPS can automatically charge and discharge, thus the service life of the battery can be effectively prolonged.

Description

Technical field: [0001] The invention relates to an automatic maintenance control device for UPS dual-circuit power supply, which controls the UPS power supply as an uninterrupted power supply of a server. Background technique: [0002] The existing UPS uninterruptible power supply generally has three deficiencies: one is to adopt a power supply mode. When the power supply of the road fails, the UPS cannot be replenished with electric energy in time. When the battery power of the UPS is exhausted, the server will lose power. ; Second, the UPS battery cannot be charged and discharged automatically. The discharge process requires manual monitoring, and the discharge frequency is not standardized, which greatly reduces the service life of the battery. Safe use of electricity for electrical equipment. Invention content: [0003] The purpose of the present invention is to provide a dual-circuit power supply automatic maintenance control device for UPS to realize dual-circuit p...
