DCS800直流調速器維修廠家，ABB直流調速器維修技巧
ABB直流調速器的常見型號DCS400,DCS500,DCS800都有相同的結構，主要電路由三部分組成，分別是電源驅動板、CPU主板、勵磁驅動板，CPU電路一般都是穩定性很高的電路，勵磁驅動電路元件較少，維修相對容易，而電源驅動板不僅故障率高，維修也相對比較困難一些，所以本文結合我們在ABB維修工作的總結的經驗，淺顯的分析一下開關電源的維修技巧，一家之言，不足之處望大家指正。
開關電源是為整機全部電路提供電壓的主要電路，供電為交流220伏，由X98進入，經過兩只限流電阻后由整流橋整流，再經CLC電路濾波，作為開關電源的直流電源，整個電路包含：振蕩回路、穩壓回路、自供電回路、保護回路、負載回路。
