回扫变压器中的电晕检测

THE DETECTION OF CORONA IN FLYBACK TRANSFORMER

本文主要对回扫变压器中的各种电晕放电现象进行了分析,并指出回扫变压器中电晕放电和一般工频变压器中电晕放电的差异。在此基础上介绍一种实用的并已广泛用于生产检测的电晕测试仪,对显示器上显示的波形也进行了分析,通过分析可以大致判断回扫变压器中可能存在的缺陷。

Having analysed all kinds of corona discharge in flyback transformers, the author points out the corona discharge differences between flyback transformers and ordinary industrial frequency transformers, and on this base introdues akind of corona detector that is pratical and has been widely used of detection of production, meanwhile analyses the waveform showed in the oscillograph aswell. The posible defect in the flyback transformers can judged mostly through analysis.
