Abstract

The invention provides a high-voltage double-pulse superposed power supply for an electrostatic dust collector. The high-voltage double-pulse superposed power supply for the electrostatic dust collector adopts three-phase input, and adopts a series resonant mode through a resonant circuit to realize zero current shutdowns; and the highest output pulse frequency is designed to be 40KHZ. The high-voltage double-pulse superposed power supply for the electrostatic dust collector effectively solves the problem of insufficient power of the high-frequency pulse power supply in the prior art, and hasthe advantages of the high-frequency pulse power supply of three-phase balance, small ripple factor, high flashover voltage and constant current characteristics; the generation of anti-corona can be avoided for high specific resistance dust; and meanwhile, the double pulse is superposed, therefore, the ultra-fine dust collection is improved, and the dust removal efficiency and power application range are improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a high-voltage double-pulse superimposed power supply for electrostatic dust removal, which is widely used in thermal power, steel, cement, nonferrous smelting, coal coking, chemical industry, electronics, flocking and other electrostatic deposition sites. Background technique [0002] Electrostatic precipitators often use high-frequency power supplies. Due to the difference in principle, high-frequency power supplies have three-phase balanced input, small output ripple, high average voltage and current, small transformer volume, high conversion efficiency and power factor, etc. A number of significant advantages, especially the dust removal efficiency can be greatly improved. However, the disadvantage of the existing high-frequency switching power supply is that there is relatively serious switching interference. In the high-frequency switching power supply, the p...
