Problems solved by technology

[0002] Existing oil wells are used in oil wells. Due to the low temperature in the ground, the oil is relatively viscous and difficult to collect. It is necessary to heat up the oil to make the heavy oil in the ground flow easily. However, the circuit of the existing heating heavy oil system needs to use isolation Transformers are used to rectify the circuit, which wastes resources and energy, and cannot be used together between single-phase and multi-phase

Abstract

The invention relates to single-phase, two-phase, three-phase and multi-phase symmetrical-peak dual-voltage rectifying basic circuits and particularly relates to application on a thickened oil heating system of an oil well. On the basis of single-phase, two-phase and three-phase rectifying output circuits, a capacitor is connected by a new method, peak symmetry and dual-voltage rectification are achieved, positive electric potential and negative electric potential are switched on through switching elements, no isolation transformer is required to be added, a sucker rod is heated, the heat production efficiency is improved, resources and energy are saved, and circuits can be used commonly in a single phase and multiple phases.

Description

technical field [0001] The invention relates to a basic circuit involving single-phase, two-phase, three-phase and multi-phase peak symmetry and voltage doubler rectification, in particular to a circuit used in an oil well heating heavy oil system. Background technique [0002] Existing oil wells are used in oil wells. Due to the low temperature in the ground, the oil is relatively viscous and difficult to collect. It is necessary to heat up the oil to make the heavy oil in the ground flow easily. However, the circuit of the existing heating heavy oil system needs to use isolation Transformers are used to rectify the circuit, which wastes resources and energy, and cannot be used together between single-phase and multi-phase. Contents of the invention [0003] In view of this, it is necessary to provide a resource-saving, energy-saving, single-phase and multi-phase common use, and energy-saving circuit for oil well heating heavy oil system. [0004] The present invention i...
