High-voltage power supply of electrostatic dust collector

Abstract

The invention discloses a high-voltage power supply of an electrostatic dust collector, which comprises a switch stabilized voltage power supply, a high-voltage power supply and a current-voltage control circuit. The high-voltage power supply of the electrostatic dust collector is also connected with an automatic regulation module; the automatic regulation module consists of a current sampling circuit, a pulse converting circuit, a logic gate array and an amplifying circuit which are connected in turn; the automatic regulation module detects the magnitude and duration of the current loaded bythe high-voltage power supply; and an output of the automatic regulation module is connected with the current-voltage control circuit and provides different reference voltages for the current-voltagecontrol circuit respectively. The high-voltage power supply of the electrostatic dust collector is controlled by multi-shift constant-current limit voltage, implements multi-shift automatic control for an electrostatic power supply and automatic alarm for power supply failure, and has the advantages of complete function, good adaptability and excellent technical performance.

Description

Technical field: [0001] The invention relates to a power supply device, in particular to a high-voltage power supply for an electrostatic precipitator. Background technique: [0002] The power supply of the existing electrostatic precipitator is generally only a simple high-voltage rectifier output circuit, and the current and voltage are automatically adjusted and designed, which makes the electrostatic precipitator unable to adapt to different regions, different climates, different environments, different humidity, and different working conditions. work below. For example, in some humid and rainy places in southern my country, the air insulation resistance is small, and the existing electrostatic precipitator has no current adjustment gear, so the current of the power supply cannot be effectively controlled under humid conditions, which is easy to cause equipment burnout, safety Poor performance. Another example is that in some places with high dust density, the electrode...

Problems solved by technology

In addition, the arc discharge of the electrode of the electrostatic precipitator to remove dust, bacteria, and mosquitoes will inevitably lower the voltage and current. If it cannot be automatically adjusted, it will seriously affect the normal operation of the electrostatic precipitator.
