中波PDM固态机的检修与维护

Examination and Maintenance of WM PDM Solid-state Transmitters

随着科学技术的进步,越来越多的固态化发射机取代了传统的电子管发射机。我国的许多地区已完成了广播发射机的更新换代。维护人员迫切需要更新知识结构,将学习重点从熟悉的电子管发射机转换到固态发射机上来,及时掌握全固态发射机的特点和维护技术,才能充分发挥全固态发射机高可靠性的优点,实现"高质量、不间断,既经济、又安全"的播出任务。

With the development of science and technology, more and more solid-state transmitters have replaced the traditional electron tube transmitter, and the replacement has taken place in many parts of China. So it is urgent for us maintenance staff to update the knowledge structure and shit the focus form the familiar electron tube transmitters to solid-state transmitters and master the characteristics and maintain skills of all solid-state transmitters to fully utilize their advantage of high reliability and realize the high-quality, uninterrupted,economic and safe broadcasting.
