[0002] When the transformer busbar is inspected and replaced on site, the busbar encapsulation sleeve needs to be removed before the busbar can be disassembled for test inspection or replacement. After the work is completed, the busbar needs to be re-encapsulated. At present, the conventional busbar encapsulation method is to use an encapsulation sleeve for encapsulation, but since the encapsulation sleeve is sealed up and down with rivets, and this method is very easy to damage the encapsulation sleeve, when the inspection is completed and restored, the sealing performance of the opened encapsulation sleeve will be greatly reduced; if this encapsulation sleeve is continued to be used, it will easily cause water and dirt to enter the encapsulation sleeve, and the busbar will rust, which will bring hidden dangers to the safe power supply of the system.
