摘要
随着我国广电技术的迅速发展,固态发射机体积更小,电路集成度更高,同时,设备的使用与维护要求也更为严格。我台所用正泰PDM1kW中波广播发射机具有体积小、效率高、指标优、维护方便等优点,在国内很多地区得到了广泛应用。本文以该广播发射机为例,分析常见故障与处理策略,供工作人员参考,以确保广播发射机的正常稳定运行。
With the rapid development of radio and television technology,solid-state transmitter has smaller volume and higher circuit integration.At the same time,the use and maintenance requirements of equipment are increasingly strict.Chint pdm1kw medium wave broadcasting transmitter has the advantages of small size,high efficiency,excellent index and convenient maintenance,which has been widely used in many areas of China.This paper takes the broadcast transmitter as an example,analyzes the common faults and processing strategies,in order to provide reference for relevant technical personnel,and ensure the normal and stable operation of the broadcasting transmitter.
