Intelligent voltage-regulation alternating-current electric desalting power unit

Abstract

The invention relates to an intelligent voltage-regulation alternating-current electric desalting power unit. An external electric energy input is connected with a primary coil of a booster transformer through an output end of an electronic voltage regulator controlled by an electronic trigger control circuit, and a secondary coil of the booster transformer is connected with a plate electrode in the electric desalting unit. The electronic voltage regulator is composed of forward and reverse silicon controlled rectifiers which are connected in parallel, wherein control electrodes of the forward and reverse silicon controlled rectifiers are respectively connected with forward and reverse output control ends of the electronic trigger control circuit. The electronic trigger control circuit comprises a feedback circuit, a comparison circuit, a trigger circuit and an output circuit.

AI Technical Summary

Problems solved by technology

The power supply is a special power supply for high-speed electric desalination and electric dehydration equipment, and 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 cannot be suppressed in time, which greatly The power consumption of the equipment is greatly increased, 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

The rectifier box part of the original AC / DC desalination electric dehydrator power supply is relatively large, which is prone to failure, which is not conducive to the operation and maintenance of the equipment
