电子调光设备无线电干扰的测量及抑制

在电视照明技术系统中,电子调光设备的选择和应用是关键,抑制干扰是技术难点,建立规范是大势所趋。本文通过大量测试数据,分析研究电子调光设备干扰产生的原因和危害、传导和辐射干扰的相互关系、测量方法、抑制措施。在此基础上,如何制定“电子调光设备无线电干扰允许值和测量方法”国家标准和研制开发ＺＷ－１型抑制电感器等内容。

The Measurement and Restrain of Radio Interferencein Electronic Lighting Equipments

In television lighting systems,the selection and application of electronic lighting equipment are the key,the interference restrain is the difficulty,and the standardization is a generaltrend. This paper through a vast amount of data,analyses the reasons and harmfulness of interferences in electronic lighting equipments,the relationships of conduction and radiation interference,the measurements and restraint methods. Based on this,the author introduces how to draw up anational standard of "Radio interference threshold and measurements in electronic lighting equipments".
