An oil-immersed transformer oil tank

Abstract

An oil-immersed transformer oil tank, including a tank body, an end cover, an oil filling tank, a buoyancy ball, a first connecting rod, and a second connecting rod; the tank body is provided with a flange plate and two sets of collecting parts; the end face of the collecting part There is a collection tank; there are multiple sets of heat dissipation pipes in the box; the nozzle of the heat dissipation pipe is connected to the inside of the collection tank; the end cover is pressed against the flange plate; the fuel tank is connected to the end cover; The first sealing pipe and the second sealing pipe run through the end cover, and the oil filling part on the oil filling tank is provided with a hollow chamber; the hollow chamber is provided with multiple sets of oil filling holes on the outer peripheral surface of the oil filling tank, and the sliding device inside the hollow chamber There is a sealing plug; one end of the sealing plug is connected to the inner wall of the hollow chamber through the elastic connector, and the sealing plug is connected to the resistance arm of the lever through the second connecting rod; the first connecting rod is connected to the buoyancy ball, and passes through the first sealing tube and is flexibly connected The power arm of the lever. The invention can automatically add oil to the oil tank equipped with transformer components, and the oil in the tank has good cooling effect.

[0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The transformer is currently a relatively important equipment in power construction and has been widely erected in various parts of our country. ;Oil-immersed transformer is a box-type transformer in which mineral oil is used as the main insulating medium and cooling medium of the transformer, the main components of the transformer are immersed in an oil tank filled with mineral oil, and the terminal is drawn out on the top of the oil tank cover. Oil-immersed transformer Compared with other types of transformers, its structure is relatively simple, the cost is relatively low, and the maintenance cost is low, so it is widely used and is an indispensable electrical equipment in the current power supply network system; however, oil-immersed transformers will generate a large amount of electricity during operation. The thermal energy makes the temperature of the oil in the tank rise. If the oil cannot be dissipated, the performance of the transformer will be reduced, and it will be damaged in serious cases. In addition, when the oil consumption in the transformer oil tank is reduced or the oil tank is broken, the oil drips, making If the transformer fails to be protected and cooled by oil, the service life of the transformer will be greatly reduced; therefore, an oil-immersed transformer oil tank is proposed in this application
