The invention relates to an unloading and locating technology for large
electrical equipment, in particular to an unloading and locating method for an ultra-high-
voltage transformer. According to the method, a slipper pillar shaped like a Chinese character tian is used as a support for transfer, the
transformer is firstly transferred onto the slipper pillar from a flat car by jacking four ends of the
transformer by a hydraulic
oil pump, then the ground clearance of the transformer is adjusted, and finally, the transformer is moved to an specified position through steel rails. According to the unloading and locating method for the ultra-high-
voltage transformer, in combination of accurate operation data, the slipper pillar shaped like a Chinese character tian is stable, safe and reliable, and positions of a hoisting point and jacking points are selected reasonably in an unloading and locating process, so that equipment is not deformed under stress; when the transformer is hoisted,
underlay is used for protection timely, moving or inclination of the transformer due to a crane fault is prevented, and the
equipment safety is guaranteed; and the transformer maintains stable without shaking or bumping, the requirement that three-dimensional
impact on the transformer is not larger than 3 g is met, the process is simple, time and labor are saved, and the method is convenient and simple.
