Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below.

[0030] A process for immersing a transformer body in oil, comprising a pressurizing valve connected to an oil cylinder through a pressurizing pipeline, and connected to a compressor through the pressurizing valve; a vacuum valve connected to the oil tank through a vacuumizing pipeline, and connected to the Vacuum pump, its oil immersion process is:

[0031] 1) Pressurize the inside of the transformer to accelerate the discharge of oil inside the transformer;

[0032] 2) After the oil inside the transformer is discharged, use a spatula and a wire brush to remove the sludge and rust on the surface;

[0033] 3) Scrub with heated trisodium phosphate solution, rinse with clean water after scrubbing.

[0034] 4) Filter and remove impurities from the oil to be injected into the transformer through...

Abstract

The invention provides an oil immersion process for a transformer body. Oil immersion equipment for the transformer body comprises a pressurization valve connected with an oil cylinder through a pressurization pipeline, a compressor connected through the pressurization valve, a vacuumizing valve connected with an oil tank through a vacuumizing pipeline, and a vacuum pump connected through the vacuumizing valve. By virtue of the oil immersion process, the standing time of the transformer can be shortened, and the delivery time can be accelerated.

Description

technical field [0001] The invention relates to a processing technology of electric power equipment, in particular to an oil immersion technology of a transformer body. Background technique [0002] Vacuum oil immersion is suitable for oil immersion treatment of high-frequency transformers, low-frequency transformers, inductance coils, motors, and inductors. The main function of oil immersion is to fix the coils, increase the mechanical strength and insulation strength of the coils, promote heat dissipation, and prevent moisture and mildew , noise reduction and other functions; resin filling of various metal film capacitors, electrolytic capacitors, vacuum degassing process for medium / small resin crafts, and vacuum degassing process for various plastic PU raw materials. Can improve product quality, reduce production costs, save efficiency and protect the environment. In addition, the temperature, drying temperature and drying time of vacuum immersion oil are very strict. ...
