摘要
开关电源在石化控制现场用量很大,但由于其会产生电磁干扰,在一定程度上限制了它的使用。本文分析开关电源电磁辐射的产生以及对生产影响,给出对工程低压电源设计审核、日常维护中电磁干扰排查的几条建议。
Switch power supply are widely used in petrochemical industry,however,its application is limited by its electromagnetic interference.This article describes the electromagnetic radiation in switching power supply and its effects on production.Suggestions are offered about low voltage power supply checking in engineering design and electromagnetic interference identification in daily maintenance.
