The invention relates to a trolley for replacement of current transformers of centrally installed switchgears, and in particular to a trolley for replacement of a flip-chip current transformer of a centrally installed switchgear. The problems that in the prior art, people still have to enter a switch cabinet to replace flip-chip 10 kV current transformers, manpower and labor are wasted, working difficulty is high, and large potential safety hazards exist. The trolley comprises a fork arm lifting device fixed between a supporting platform and a base of the trolley, a hydraulic pump fixed on the fork arm lifting device, and a lifting handle connected with the hydraulic pump. The hydraulic pump is controlled through the lifting handle to drive the fork arm lifting device, the height of the supporting platform is controlled, and then the flip-chip current transformer of the centrally installed switchgear can be replaced. The trolley has multiple beneficial effects of being easy and convenient to operate, flexible to move, small in occupied space and the like, is applicable to complex working sites with narrow space, and completely meets rules of an electric power security working regulation. The trolley is applicable to replacement of conventional 10 kV current transformers and part of 10 kV voltage transformer in centrally installed switchgears.
