Can a high-voltage transformer cabinet be repaired while it is still in operation?

Ahaha, I’m working overtime on National Day today to answer this fellow traveler! For 10kV PT cabinets that are faulty, they can be put into use as a temporary solution after replacement; however, it is important to note that when the high-voltage fuse on the primary side blows during operation, this must be properly identified and reported promptly. The automatic devices should be shut down immediately before the disconnect switch of the voltage transformer can be opened (if available). If necessary, the secondary side fuse can be removed (or the secondary switch of the voltage transformer can be disconnected). After ruling out faults in the voltage transformer, replace the blown high-voltage fuse and bring the high-voltage transformer back into operation; once it is functioning properly, activate the automatic control device. Under normal circumstances, the voltage transformer should be taken out of service along with the busbar. That is, when the busbar is taken for maintenance, the voltage transformer is also taken for maintenance or put into cold standby ； When the bus is in cold standby, the voltage transformer should be put into operation. When shutting down the equipment, the fuse on the low-voltage side of the voltage transformer or the small switch on the secondary side of the voltage transformer should be removed first to prevent back-feeding.
