The invention discloses a main transformer jacking method and device. The device comprises a hydraulic pump, a synchronizing system, a motor and four hydraulic jacks, wherein the motor is used for driving the hydraulic pump; the synchronizing system is provided with an input end and four output ends; the input end is connected with the hydraulic pump through a pipeline; the four output ends are connected with the four hydraulic jacks through pipelines respectively; and the synchronizing system is used for synchronously conveying pressure oil of the hydraulic pump to the four hydraulic jacks. According to the method, the device is applied to jacking operation of a main transformer. The synchronization error of the device is small, and the safety of the operation process is greatly improved;and when the device is used for jacking the main transformer, time and labor are saved, and the effect is good.

    本发明公开了一种主变压器顶升方法及装置。该装置包括液压泵、同步系统、电机和四个液压千斤顶;所述电机用于驱动液压泵;所述同步系统具有一个输入端和四个输出端,输入端与液压泵管道连接,四个输出端分别与四个液压千斤顶管道连接,同步系统用于将液压泵的压力油同步输送至四个液压千斤顶。该方法为将上述装置运用于主变压器的顶升作业中。该装置的同步误差小,大大增加作业过程的安全性;使用该装置进行主变压器顶升,省时省力,效果好。
