The invention provides a power grid transformer bushing hoisting method which comprises the following steps: determining a hoisting scene of a transformer bushing, and completing preset preparation items, namely driving a crane lifting hook to a hoisting position of the bushing, firmly binding the bushing and hanging the bushing on the crane lifting hook; one end of the traction rope is fixed to the sleeve lead conducting rod, and the other end of the traction rope falls to the ground. The traction rope is connected to a fixed pulley which is installed on the outermost auxiliary arm of the crane suspension arm in advance in a sleeving mode. And after the preparatory items are completed, according to the scene, selecting a corresponding preset scheme for hoisting, so that the bushing lead is not subjected to pulling deformation or extrusion deformation until hoisting is completed. According to the invention, the problems that the bushing cannot be pulled out due to clamping stagnation in the bushing conductive tube and the bushing voltage-sharing ball crushes the insulation of the lead are solved, and the operation safety of the main transformer is improved.

    本发明提供一种电网变压器套管吊装方法,包括确定变压器套管吊装的场景,并完成预设的准备事项为驱动吊车吊钩至套管的起吊位置后,将套管绑扎牢固并挂在吊车吊钩上,以及在预先安装于吊车吊臂最外一节副臂上的定滑轮上套接有一端与套管引线导电杆固定且另一端坠地的牵引绳;待准备事项完成后,根据场景,选择相应的预定方案进行吊装,以使套管引线不发生拉扯变形或挤压变形至吊装完成为止。实施本发明,解决现有套管引线在套管导电管中卡滞无法拉出套管及套管均压球压伤引线绝缘的问题,提高了主变运行安全性。
