Abstract

The invention relates to a three-phase high-frequency inversion high-voltage rectification electrostatic dust collection integrated power supply. The power supply is formed by integrating a three-phase power-frequency low-voltage rectifier SZ, a filter CL, a three-phase high-frequency low-voltage inverter PF, a three-phase high-frequency low-voltage input/multi-phase high-frequency high-voltage output transformer PB and a multi-phase high-frequency high-voltage rectifier PZ in a sequentially connected mode. By the adoption of the three-phase high-frequency low-voltage inversion structure PF, efficiency and reliability of the high-frequency inverter can be improved. By the adoption of the multi-phase boosting transformer structure PD, efficiency and safety of the high-frequency transformer can be improved. By the adoption of the multi-phase rectification structure PZ, high-frequency rectifier efficiency can be improved, and higher harmonic can be lowered. The three-phase high-frequency inversion high-voltage rectification electrostatic dust collection integrated power supply has the advantages of being high in power, efficiency and reliability, low in harmonic, material consumption and energy consumption, and the like.

Description

technical field [0001] The invention relates to an integrated power supply for electrostatic dust removal, in particular to a three-phase high-frequency inverter high-voltage rectification integrated power supply for electrostatic dust removal suitable for large-capacity high-voltage electrostatic dust removal. Background technique [0002] With the increasing amount of industrial dust and waste gas emissions, the environmental pollution is becoming more and more serious, especially in metallurgy, mining, electric power, building materials, chemical industries and other industries. my country is a large coal-producing country, but also a large coal-consuming country. Coal accounts for about 70% of my country's energy structure, so it is also a large coal dust emission country. Coal burning has become one of the main causes of low energy efficiency, high pollution and even heavy smog. The application of high-voltage electrostatic precipitator can effectively collect dust tha...
