Abstract

The invention discloses a high-frequency pulse crude oil dehydration transformer for electrically dehydrating crude oil of an oil field and electrically raising high-frequency pulse with the frequency of 5,000-50,000Hz and the voltage of 500V into the voltage of 30,000V. The high-frequency pulse crude oil dehydration transformer is characterized in that a transformer iron core is formed by winding silicon steel strips with different thicknesses ranging from 0.03 mm to 0.20 mm respectively according to different positions of the silicon steel strips in the iron core and the vortex loss is reduced. In addition, the transformer has an integral explosion-proof structure, wherein the input end is in a safety-improving explosion-proof structure, and the output end and a transformer body are in oil-filling explosion-proof structures, thus the transformer meets the requirement of an oil-gas environment on electric equipment. Compared with the traditional transformer, the input and output voltage waveform of the high-frequency pulse crude oil dehydration transformer is the high-frequency pulse; the transformer has the advantages of wireless adjustment of output voltage, the frequency and duty factor, wide application range and stable running; and during treating complicated emulsion with strong conductivity, the transformer can ensure the stability of an electric field of a dehydrator, improve the dehydration effect of crude oil, and solve the dehydration difficult problem of the complicated emulsion in an oil field.
