Abstract

The invention provides a flange plate rapid-connecting device and an operation method thereof and belongs to the technical field of flange plate sealing and connecting of oil feeding and draining valves of transformers. The flange plate rapid-connecting device comprises a transformer oil feeding and draining pipe, an oil pipe self-sealing connector, a transformer oil feeding and draining valve flange, an oil pipe connector flange, a sealing gasket, an adjusting steel pipe, a chuck and buckles. The adjusting steel pipe is arranged coaxially outside the oil pipe self-sealing connector. A plurality of assistant member connecting holes and a plurality of threaded holes are formed in the adjusting steel pipe. The adjusting steel pipe is provided with an external threaded face. The chuck is provided with an internal threaded face which is matched and connected with the external threaded face, and a vertical face perpendicular to the internal threaded face. The multiple buckles are connected to the end of the vertical face through hinges. The flange plate rapid connecting device is safe, reliable, suitable for oil feeding and draining operations of oil outlets with all sizes of the transformers, rapid, convenient and capable of greatly shortening sealing and connecting time of flange plates of the transformers, relieving the work intensity of maintainers and improving the working efficiency, and the maintenance frequency is greatly reduced at the same time.

Description

technical field [0001] The invention belongs to the technical field of flange sealing connection of transformer oil filling and discharging valves, and in particular relates to a flange quick connecting device and an operation 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 th...
