Abstract

The invention provides a connecting device for an electric flange plate and an operation method thereof, and belongs to the technical field of transformer oil filling and draining valve flange plate sealing connection. The connecting device for the electric flange plate comprises a transformer oil filling and draining pipe, an oil pipe self-sealed connector, a transformer oil filling and draining valve flange, an oil pipe connector flange, a sealing gasket, a chuck, clamping buckles and electric pushing rods. The sealing gasket is arranged between the oil pipe connector flange and the transformer oil filling and draining valve flange. The electric pushing rods are arranged outside the oil pipe self-sealed connector which is sleeved with the chuck. One end of the chuck is connected with the electric pushing rods, and the other end of the chuck is connected with the multiple clamping buckles through hinges. The connecting device for the electric flange plate is safe and reliable and can be applied to oil filling and draining operation of all transformer oil outlet sizes, the time for sealing and connecting of transformer flange plates is greatly shortened, operation is fast and convenient, the working intensity of maintenance personnel is relieved, the working efficiency is improved, and meanwhile the maintenance frequency is greatly decreased.

Description

technical field [0001] The invention belongs to the technical field of flange sealing connection of a transformer oil filling and discharging valve, and in particular relates to an electric flange connection device and a use method thereof. Background technique [0002] During the overhaul or installation process of power transformers, it is necessary to fill and drain the transformer oil. Due to the different sizes of oil outlets of transformer oil drain valves of different manufacturers, models, and voltage levels, the maintenance personnel need to carry connectors of various sizes when filling and draining oil each time, so as to be suitable for field equipment and bring great inconvenience to the work. A lot of inconvenience increases the work intensity of the staff, and the work efficiency is low. [0003] The Chinese patent No. 201520183084.7 discloses a transformer universal pipe joint, including a round pipe, a female flange and a sub-flange. The round pipe and the ...
