Abstract

In order to solve the problem of online bridging of low batteries in the storage battery maintenance process and realize uninterrupted continuous discharge, the invention provides a direct-current power supply storage battery online bridging device which comprises a positive electrode connecting clamp, a negative electrode connecting clamp, a Schottky diode, a battery monitor, a power converter, a comparator, a control unit, a voltmeter and an ammeter. When a low battery appears, the online bridging device can automatically bypass the battery, and no current flows through the bridged battery, so that the battery is effectively protected from being overdischarged, the battery does not need to be paused for discharging when the storage battery is subjected to check discharging, the time can be greatly saved, and the discharging safety of the battery is effectively improved; and safe, rapid and convenient maintenance work is achieved.

Description

technical field [0001] The invention relates to the field of maintenance tools for battery packs used in electric power systems, in particular to an online jumper device for storage batteries of direct current power supplies. Background technique [0002] Substation DC power supply is used as the working power supply for secondary equipment such as power system protection equipment, communication equipment, automation equipment, and computers. The working power supply is the only power supply after the AC power supply of the substation loses power. The battery pack that ensures continuous power supply requires long-term floating charging and uninterrupted work. In order to ensure the reliability of the battery, it is necessary to regularly discharge and maintain the battery. Internal resistance Test, voltage test and other methods to ensure the normal operation of the battery. Usually the rated voltage is 110V and 220V, and the battery pack is composed of 54 or 108 single 2V...
