[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

The invention relates to a method for eliminating damaged storage batteries without a power failure of a storage battery pack of a transformer substation. The method comprises the following steps of:monitoring the temperature condition of each storage battery in real time by adopting an infrared detection module, keeping the current working state of the storage battery pack when the temperature of a certain storage battery is higher than a first preset value, and notifying a worker to keep alert; when the temperature of a certain storage battery is higher than a second preset value, moving astandby storage battery pack to the storage battery by utilizing a guide rail bus; connecting the standby storage battery to the two ends of the two storage batteries at the two ends of the storage battery in parallel through two conversion electromagnetic switches; after the two conversion electromagnetic switches are switched on, switching off two isolation electromagnetic switches at the two ends of the storage battery and cutting the storage battery out of the storage battery pack; and adopting the standby storage battery to replace the cut-out storage battery. According to the invention,the faulty storage battery unit can be replaced without quitting the operation of the storage battery pack.
Description
technical field [0001] The invention relates to the field of substation design, in particular to a method for removing damaged storage batteries without power failure of a storage battery set in a substation. 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] ...
