Intelligent response special power supply of electrical desalting and dehydration equipment

Abstract

The invention relates to an intelligent response special power supply of electrical desalting and dehydration equipment, and belongs to the technical field of electrical desalting power supply. An external electric energy input is connected with primary of a step-up transformer by an output terminal of an electronic voltage regulator controlled by an electronic trigger control loop, secondary of the step-up transformer is connected with a positive electrode plate and a negative electrode plate of the electrical desalting equipment by a positive rectifier device and a reverse rectifier device respectively. The electronic voltage regulator consists of a positive thyristor and a reverse thyristor, and control electrodes of the positive thyristor and the reverse thyristor are connected with anpositive output control end and a reverse output control end of the electronic trigger control loop. The special power supply solves problems of the prior art by reasonable circuit configuration, notonly provides stable and reliable power to the electrical desalting equipment, but monitors operation of the equipment, automatically judges faults, automatically resumes operation after the fault iseliminated, and can realize stepless and active regulation of high-voltage output so as to facilitate operation and maintenance of the equipment.

Description

technical field [0001] The invention relates to a special power supply, in particular to a special power supply for intelligent response electric desalination and dehydration equipment, belonging to the technical field of electric desalination power supply. Background technique [0002] According to the applicant's understanding, the power supply device of crude oil electric desalination equipment generally adopts AC or AC or DC power supply, and the more advanced and representative one is the special power supply for high-speed electric desalination and electric dehydration equipment (see Chinese patent document No. 01201736.1 for details) ). As a special power supply for high-speed electric desalination and electric dehydration equipment, the power supply adopts 100% full impedance current limiting protection reactor. When the crude oil is emulsified in the electric desalination equipment, the large current between the output electrodes will not be suppressed in time, whic...

AI Technical Summary

Problems solved by technology

As a special power supply for high-speed electric desalination and electric dehydration equipment, the power supply adopts 100% full impedance current limiting protection reactor. When the crude oil is emulsified in the electric desalination equipment, the large current between the output electrodes will not be suppressed in time, which will greatly increase The power consumption of the equipment is reduced, which is not conducive to energy saving; the continuous high current will also rapidly increase the temperature of the power supply equipment in a short period of time, which will reduce the safety performance of the equipment

[0003] In addition, the 01201736.1 special power supply for high-speed electric desalination and electric dehydration equipment only provides power to the equipment, and when the equipment adjusts the high-voltage output of the power supply, power-off adjustment is required.
