Problems solved by technology

[0011] 3) For unit batteries with sudden severe overheating failures, especially those with open-circuit failures, it is not possible to automatically switch the normal and qualified spare batteries first, isolate the failed battery units, and then notify the maintenance personnel to come and replace them. There is no guarantee that the battery pack is in good standby working condition

Abstract

The invention relates to a system for eliminating damage to battery packs in a substation without power failure, including N batteries, N+1 conversion electromagnetic switches, 2N isolation electromagnetic switches, an infrared detection module, a guide rail bus, a backup battery and a control module; each The two ends of the storage battery pack are respectively provided with an isolating electromagnetic switch, and the two adjacent batteries are connected in series through two isolating switches, and the two ends of each battery are respectively connected to the guide rail bus through an isolating electromagnetic switch and a transfer electromagnetic switch. The invention can replace the faulty storage battery unit without exiting the running state of the battery pack.

Description

technical field [0001] The invention relates to the field of substation design, in particular to a substation storage battery system for removing damaged storage batteries without power failure. Background technique [0002] The battery pack in the substation plays an extremely important and indispensable role. The power supply for the secondary protection device, monitoring, measuring instrument, communication and switch operation device, emergency lighting, etc. of the high-voltage equipment in the substation is usually carried by the DC charging device. And float charge the battery pack, the battery pack is in the standby state of floating charge, but in the accident state of AC power failure (the DC charging device is charged by AC rectification and filtering), the battery pack is the only power supplier. If there is a problem and the power supply cannot be normal, the substation will face paralysis or even a major accident, causing heavy losses. [0003] The daily main...
