摘要
随着科技的不断进步,人们对于新闻广播收听的需求不断提高,广播业务遍布全国各地。PDM中波发射机由于传输距离远、设备简单易实现、维护成本低等原因被广泛应用在广播系统当中。为保证广播发射机达到优质的信号传播效果,对其进行日常维护以及故障诊断分析十分重要。为此,详细介绍发射机出现故障时,如何根据故障现象对故障进行分析与诊断,并列举了掉高压故障诊断实例进行说明。
With the continuous progress of science and technology,in order to meet people’s demand for news broadcast listening,the broadcasting industry is all over the country.PDM medium wave transmitter is widely used in the broadcasting system because of its long transmission distance,easy implementation and low maintenance cost.In order to ensure the broadcast transmitter to achieve high-quality communication effect,its maintenance and fault diagnosis analysis are very important.This paper introduces in detail how to analyze and diagnose the problem according to the fault phenomenon when the transmitter fails,and lists the power of high voltage fault diagnosis to explain.
