Power control system of high-performance three-phase power supply high-voltage dust remover

Abstract

The invention discloses a power control system of a high-performance three-phase power supply high-voltage dust remover, and belongs to the technical field of power supplies of high-voltage dust removers. The power control system comprises a main loop and a control system, wherein the main loop comprises a three-phase reactor, a three-phase bridge type diode rectification circuit, a flat wave capacitor, a single-phase bridge type insulated gate bipolar transistor (IGBT) inversion circuit, an inductance and capacitance (LC) filter circuit, a high-voltage transformer, a high-voltage rectifier and a high-voltage reactor; and the control system comprises an intelligent control unit, a power group board, an operation display panel, an IGBT driving control unit and a high-voltage acquisition unit. Compared with the conventional high-voltage dust remover power supply, the power control system has the advantages that a three-phase power supply is adopted, so that pollution to a power grid is low; and flash fuzzy control and a pulse width modulation (PWM) inverter technology of an IGBT device are combined, so that the dust removal efficiency is greatly improved, and an energy-saving effect is obvious.

Description

technical field [0001] The invention belongs to the technical field of power supply for high-voltage electric precipitators, and in particular provides a high-performance three-phase power supply control system for high-voltage electric precipitators. Background technique [0002] The basic working principle of electrostatic precipitator is: when the dust airflow passes through the high-voltage electrostatic field, it is ionized and the dust absorbs negative charges to become carriers. Under the action of the electric field, the carriers are finally adsorbed by the positive electrode, so as to achieve the dust collection effect. Electrostatic precipitator (ESP) is an internationally recognized high-efficiency dust removal equipment, which has the advantages of reliable operation, convenient maintenance and low power consumption. It has been used in thermal power plants, steel, metallurgy, papermaking, cement, textile, Chemical and other fields are the main means of dust remo...
