摘 要:針對工頻電源電除塵器除塵時電場電壓波動大、火花控制性能差等的不足,把傳統(tǒng)的工頻電源改造設(shè)計成高頻電源,使電除塵器各項關(guān)鍵指標得到很大的提高,給出了高頻電源設(shè)計原理,并對高頻電源性能進行了分析,經(jīng)過燃煤電廠實際應(yīng)用,取得了良好的效果。
關(guān)鍵詞:高頻電源;電除塵器;節(jié)能;除塵效率

Abstract: In allusion to the deficiency of large electric field voltage fluctuation and uncontrollable cremation performance, the traditional power supply of industrial frequency was reformed and promoted to the high frequency power supply, to make each key index of electrostatic precipitator increased greatly. This paper gave the design principle of high frequency power supply and analyzed the high frequency power supply. The practical application of coal fired power plant shows the good results.
Key words: high frequency power; electrostatic precipitator; energy conservation; precipitate efficiency
