Abstract

The invention proposes a power supply control system for an electric dust collector, and belongs to the field of power equipment. The power supply control system comprises a PWM (Pulse Width Modulation) wave level conversion circuit board and a master control circuit board, a power frequency power supply driving circuit board and a three-phase power supply driving circuit board which are connected with the PWM wave level conversion circuit board, wherein the power frequency power supply driving circuit board is connected with a power frequency power supply, and the three-phase power supply driving circuit board is connected with a three-phase power supply. The master control circuit board is shared by combining the power frequency power supply driving circuit board with the three-phase power supply driving circuit board, so that the power supply control system can be simplified, and the production cost of the electric dust collector is reduced and the master control circuit board is also used for achieving control on two power supplies, the universality of the control system between the power frequency power supply and the three-phase power supply is improved, and the universality of the control system is improved.

Description

technical field [0001] The invention belongs to the field of power equipment, in particular to a power supply control system for an electric precipitator. Background technique [0002] The power supply used in the electrostatic precipitator includes industrial frequency power supply (or single-phase power supply) and three-phase power supply. The input of the industrial frequency power supply is a two-phase 380V power supply. A group of anti-parallel thyristors are connected in series in one of the phases, and then input to the industrial frequency transformer to realize boosting and rectification, and finally output high-voltage direct current to the electrostatic precipitator. The input of the three-phase power supply is a three-phase 380V power supply. A group of anti-parallel thyristors are connected in series on each of the three phases, and then input into a three-phase transformer to realize boosting and rectification, and finally output high-voltage direct current to...
