摘要/Abstract

摘要： 电除尘器高压供电设备在适应运行工况要求和提高电除尘器整体性能方面起着极其重要作用。分析了国内几种高压电源的特点及性能，详细介绍了国内研发的提效节能型电除尘器高压供电控制设备，该设备具有有效克服反电晕危害，提效减排的同时可大幅降低能耗等特点。最后指出，我国多年来一直采用的大功率、高能耗的火花自动跟踪供电方式应尽快转移到高峰值电压、低平均电压、小电流的提效节能供电方式上来。

Abstract: The high voltage power supply device of EP plays a significant role in adaptation of EP to operation condition and raising global function of EP. The features and functions of several domestic high voltage power sources were analyzed. A new high voltage power source control device of EP developed at home was introduced in detail. This device has advantages of effectively eliminating the damage of discorona, increasing the dust removal efficiency and lowering electrical energy consumption at large amplitude. It is pointed in the end of this paper that the high voltage power supply mode of spark automatic following, which has been used in our country widely for many years, is of great power and high energy consumption, and it should be replaced by efficiency-enhancing, energy-saving high voltage power supply mode, which has higher peak voltage, lower average voltage and smaller current, as soon as possible.

Key words: electric precipitator（EP）, high voltage power source, discorona, efficiency-enhancing and energy-saving, impulse-type power supply, dust removal efficiency
