Problems solved by technology

[0004] (1) Due to the tailing phenomenon of the pulse waveform, it is difficult to achieve the ideal pulse dehydration effect, and the steepness of the rising and falling edges of the pulse waveform is poor, which makes the energy accumulation poor during the dehydration process;
[0005] (2) In the link before the rectification part, due to the use of a power frequency transformer, the entire system consumes a lot of energy, and there is still a certain space for energy saving. At the same time, due to the use of a power frequency transformer, the volume of the entire device is relatively large;
[0006] (3) Voltage regulation accuracy is not high

Abstract

The invention relates to an energy saving and large pulse power supply for crude oil electric dehydration and the production method thereof. The large pulse power supply comprises a low voltage dc power supply device outputting a low voltage dc power supply, a large power inversion device inverting the low voltage dc power supply and outputting a bipolar low voltage pulse power supply, a pulse transformer device improving voltage of the bipolar low voltage pulse power supply and outputting a high voltage dc power supply, a pulse switch device making the high voltage dc power supply be a high voltage and high frequency pulse power supply output to a load, a detection device and a control device. Firstly the bipolar low voltage pulse power supply is formed by the treatments of rectification,filter and inversion to the ac power supply, then the high voltage dc power supply is formed by treatments of voltage rise, rectification and filter to the pulse transformer, finally the high voltageand high frequency pulse power supply is formed by crossing the pulse switch with a complementary structure. The energy saving and large pulse power supply of the invention has advantages of frequency modulation, amplitude modulation, pulse width modulation, wide current range, non-harmonic pollution, energy conservation and small size or the like.

Description

technical field [0001] The invention relates to a high-frequency, high-voltage, high-power pulse power supply, in particular to a high-power pulse power supply for electric dehydration of crude oil and a production method thereof. Background technique [0002] Studies have shown that high-frequency, high-voltage, and high-power pulse power supplies have good application prospects in the petrochemical field (such as electric demulsification, solvent extraction, oil-water separation and other production processes). But so far, there are still many technical problems in the frequency-adjustable, amplitude-modulated, pulse-width-modulated, energy-saving high-frequency, high-voltage, and high-power pulsed power supplies produced by existing technologies. There are no application examples yet. [0003] Chinese patent (application number 200610008306.7) proposes a "generation method of high-frequency high-voltage pulse power supply and high-frequency high-voltage electric pulse", ...
