Variable-frequency regulating transformer for oil production in deep well

Abstract

A variable-frequency regulating transformer for oil production in a deep well relates to a special power transformer for petrochemical equipment. The variable-frequency regulating transformer is composed of a primary electricity transformer, a frequency converter, a mutual inducer, a rectifier, a reactor, a filter, an oil immersion tank, an on-load tap-charging switch, a high-voltage output terminal sleeve, an outer attaching box of the primary electricity transformer, an input terminal, a measuring terminal and a connecting flange sleeve, wherein the frequency converter and the mutual inducer are arranged in the outer attaching box of the primary electricity transformer; the outer attaching box is provided with the input terminal and the measuring terminal; the reactor, the rectifier and the filter are placed into the oil immersion tank, and the on-load tap-charging switch and the high-voltage output terminal sleeve are arranged on the exterior of the tank; and all electrical components arranged in the oil immersion tank and the outer attaching box of the primary electricity transformer are effectively connected and then connected with the oil immersion tank and the primary electricity electric transformer through the connecting flange sleeve. The invention provides a new power transformer for desalting-purifying equipment which is used to collect crude oil in the deep well; and meanwhile, the transformer provided by the invention can change a voltage at random according to the work efficiency and can implement a voltage-regulating function in the on-load state.

Description

technical field [0001] The invention relates to a special power transformer for petrochemical equipment, in particular to a power transformer for crude oil purification equipment. Background technique [0002] Crude oil obtained from deep well oil production contains a large amount of impurities such as inorganic salts, which must be desalted and purified before refining. The desalting and purification process of crude oil is carried out in a special equipment. The basic principle is to dissolve the inorganic salts in water through the demulsifier to the emulsion formed after the exploitation of crude oil, and then apply an electric field to the emulsion, under the action of the electric field force , the brine-containing droplets are charged and polarized and coalesced, and then separated from the crude oil by sedimentation, and the brine is drawn out to achieve the purpose of purification. [0003] It is a dedicated power transformer that provides power for the desalinati...

Problems solved by technology

However, the form of the above-mentioned electric field change is set before the purification process starts, and the form of the electric field cannot be changed randomly during the process.

If you want to change the electric field strength with a changing voltage during the desalination and purification process, that is, randomly change the voltage under load, it cannot be realized with the known existing special power transformer
