Problems solved by technology

[0002] For oil-immersed transformers of 66kV and above substations, the amount of oil-filled transformer supplementation is very large. The current method of oil supplementation is to use multiple people or use cranes and other auxiliary tools to support the metal expander to expose the oil supply hole when filling oil. , to carry out the oil filling, this method is time-consuming and laborious, the oil filling efficiency is low and many people need to participate to complete the oil filling operation

Abstract

The invention relates to the field of oil immersed type mutual inductors, in particular to an oil recharging device of an oil immersed type mutual inductor. The oil recharging device is characterized in that a lifting screw rod, a supporting arm and a hoisting rod are included, the root portion of the supporting arm is connected with the lifting screw rod through threads, a supporting screw rod is arranged at the hook end of the supporting arm, the supporting screw rod is connected with a tray at the top of the oil immersed type mutual inductor, the lower end of the lifting screw rod is movably connected with the middle of the hoisting rod, and a handle is arranged on the upper portion of the lifting screw rod. The end of the hoisting rod is hinged to a claw hook, and the hook end of the claw hook corresponds to the outer edge of a metal expander disc. Compared with the prior art, the oil recharging device has the advantages that the oil recharging device adapts to the supporting strength and telescopic height of a metal expander on the oil immersed type mutual inductor, hoisting and oil recharging can be carried out on the metal expander disc by one person, the current oil recharging mode with multiple persons participating is replaced, convenience is provided for daily work, time is brought for maintenance work, and the safety of the oil injection operation is greatly improved.

Description

technical field [0001] The invention relates to the maintenance field of oil-immersed transformers, in particular to an oil replenishing device for oil-immersed transformers.
