近几年,DAM数字中波发射机正以其高效率、高质量、高稳定性的优点逐步取代老式电子管发射机。先进的设备必然要有新的维护技术来保障其正常运行。新设备复杂的电子线路,对每一个广播技术维护人员来说,都面临着一个新的考验。学习和掌握新设备的原理和维修技术是每个维修人员的当务之急。下面是近几年本人在数字发射机实际维修当中所总结的几点经验与体会,在此与同行共探榷。
In recent years, DAM digital midwave transmitters are gradually replacing old-style tube transmitters for their high efficiency, high quality, and high stability. Advanced equipment must have new maintenance techniques to ensure its normal operation. The complicated electronic circuits of new equipment are facing a new test for every broadcast technology maintainer. Learn and master the principle of new equipment and repair technology is the top priority of every maintenance staff. Here are some experiences and experiences that I have summarized in the actual maintenance of digital transmitters in recent years, where I can discuss with my colleagues.
