[0002] The live installation and dismounting of the current lead line of the transformer substation is a work often encountered in the maintenance of the power system. On the one hand, the current lead clamp and the current lead in the line are prone to corrosion and loosening in the long-term uninterrupted operation in the outdoor harsh environment, which may cause the local temperature rise of the line and lead to accidents such as fuse line, and thus the original current lead needs to be live removed and the new current lead needs to be live installed. On the other hand, when the power equipment between different busbars in the transformer substation is subjected to periodic maintenance, the current lead line needs to be live dismounted to ensure the safety of the ground equipment during the maintenance process.
