Description

TECHNICAL FIELD

[0001] The utility model relates to bushing installation technical field, concretely is a bushing hoisting lead wire traction device. BACKGROUND

[0002] If the transformer bushing fails, it needs to be disassembled for repair or replacement. The high-voltage bushing is the main insulation device outside the transformer tank, and the lead-out wire of the transformer winding must pass through the insulation bushing to insulate between the lead-out wires and between the lead-out wire and the transformer shell, and also to fix the lead-out wire. When installing, a steel wire rope is generally connected between the high-voltage bushing and the lifting hook. However, when installing the high-voltage bushing, a high-voltage lead wire needs to be drawn out from the middle of the high-voltage bushing, one end of which is connected to the high-voltage bushing base of the transformer or the reactor, and the other end is connected to the high-voltage cable or other electrical equipment.

[0003] When hoisting and installing the high-voltage bushing, because the transformer bushing is heavy and the porcelain part is easy to be damaged, the angle is difficult to adjust when hoisting in the air, and the bushing is unstable during hoisting, etc., which often causes the steel wire rope and the high-voltage lead wire to be wound together, causing great trouble in installing the high-voltage bushing, and even damaging the high-voltage lead wire. During the replacement of the oil-paper capacitor cable-through bushing, it is necessary to ensure quick and efficient replacement of the bushing, and also to ensure that the winding cable lead wire does not appear additional stress and winding breakage. The insulation paper of the lead wire winding is easy to be damaged during the bushing hoisting process, which affects the insulation. And if the cable-through lead wire is under too much stress during the replacement of the bushing, it will cause the copper wire of the cable-through lead wire to be wound and broken, the internal winding of the transformer to be damaged, and even the cable-through lead wire and the winding to be broken and separated, causing the entire transformer to be damaged. Therefore, the transformer bushing hoisting is a very difficult work.

[0004] In the past, the traction cable-through lead wire operation basically relied on the experience of the staff to pull, and the limited innovation was only optimized at the traction end or the lifting hook, such as the transformer bushing hoisting cable-through lead wire traction adjustment special tool provided by application No. 201710724194.3, which did not fundamentally solve the problem.
