In order to reach above object, the technical scheme that the utility model adopts is: the lifting dismounting platform of current transformer band limiting bracket in this high-tension switch cabinet, comprise current transformer placement platform, hydraulic jack, rack platform, the base of hydraulic jack is fixed on the middle part of rack platform upper face, the expansion link top of hydraulic jack is fixed on the base plate face middle part of current transformer placement platform, it is characterized in that: four bights of upper face of described rack platform are provided with vertical guide cylinder; Four bights of base plate face of described current transformer placement platform are provided with vertical lead, and every lead inserts in corresponding guide cylinder; Four bights of base plate face of described rack platform are equipped with connection support ear, connecing the support bar that connects swing on support ear by lateral shaft, the left and right end support bar of front side and the left and right end support bar of rear side are all connected to one by transverse link; The bottom of the bottom of the back and front supporting bar 8 of described left part and the back and front supporting bar of right part is all connected by spacing band.
The utility model is also implemented by following measure: one end of described spacing band is provided with snap close, and another butt end of spacing band is fixedly connected with by snap close.
The base of described hydraulic jack is bolted on the plate face of support platform.
Described current transformer placement platform and rack platform all have steel plate to make; Described support bar is steel pipe manufacturing.
The beneficial effects of the utility model are: the lifting dismounting platform of current transformer band limiting bracket in this high-tension switch cabinet, can not only there be enough adjustable heights, and simple in structure, cost of manufacture is cheap, be convenient to mobile, carry easy and simple to handle, can effectively avoid injury to personnel and current transformer damage in current transformer disassemble and assemble work, the current transformer that can significantly improve again in high-tension switch cabinet is installed, change operating efficiency, shorten working time, improve the economic benefit of enterprise, can be widely used in dismounting and the maintenance of the interior current transformer of high-tension switch cabinet of 10-35KV.
