【摘要】本文以醫(yī)用顯示器作為測(cè)試設(shè)備,利用控制單一變量的方法,分析了在低頻段時(shí)線纜的擺放、長(zhǎng)短等因素對(duì)傳導(dǎo)發(fā)射試驗(yàn)的影響。通過對(duì)比發(fā)現(xiàn),線纜采用短線、去耦方式布置時(shí),對(duì)公共電網(wǎng)的干擾更大。

Abstract: This article uses medical displays as testing equipment and uses the method of controlling a single variable to analyze the influence of factors such as cable placement and length on conducted emission tests in the low frequency range. Through comparison, it is found that the interference of cables on the mains network is greater when arranged in short lines and decoupling methods.

Keywords: electromagnetic compatibility; conducted emissions; cables

0引言

電磁兼容中有一項(xiàng)測(cè)試叫作傳導(dǎo)發(fā)射(Conducted Emission,CE),也被稱為傳導(dǎo)騷擾,是指電子、電氣設(shè)備或系統(tǒng)內(nèi)部的電壓或電流通過信號(hào)線、電源線或地線傳輸出去而成為其他電子、電氣設(shè)備或系統(tǒng)干擾源的一種電磁現(xiàn)象。(剩余2569字)
