Benefits of technology

This invention relates to an improved method or system that prevents excessive concentrations of harmful chemicals from being released into air pollution caused by electric precipitation devices used on roadsides. It uses special circuits designed specifically with these technical features to detect if there has been any regular fireings occurring over several hours before they disappear altogether without causing damage. By controlling the timing at which fires occur after detection, less oil mist may be produced while still maintaining good performance. Additionally, the use of specific materials helps protect against corrosion and wear out more effectively than traditional methods like metal pipes.

Problems solved by technology

This patented technology solves issues related to an electrical static precipitation (ESP) device's function when generating strong voltages for effective cleanings without causing damage from particle impact on its components.

Abstract

The invention provides a high voltage power supply circuit, a high voltage power supply board and a method for controlling High-voltage voltage output, the high voltage power supply circuit includes aboosting circuit, a detecting device and a control device. The boosting circuit has a control input terminal, a voltage input terminal and a voltage output terminal, and the boosting circuit is configured to convert a voltage inputted from the voltage input terminal into a DC high-voltage voltage and output the DC high-voltage voltage from the voltage output terminal, and the boosting circuit canprovide at least two levels of output voltages; the detecting device is used for detecting a voltage change reflecting a sparking phenomenon on the voltage output terminal; and the control device isused for adjusting the level of the output voltage of the boosting circuit according to the detected number of times of occurrence of the sparking phenomenon per unit time. The high voltage power supply board reduces the amount of ozone generated by an electrostatic precipitator, also prevents the occurrence of continuous sparking, and reduces the decibel and frequency of sparking arc noise, thereby prolonging the service life of the power supply board.
