为进一步推进我县广播电视“村村通”工程,加强农村中央广播电视节目的无线覆盖,2007年上级支持我县建设的田蓬和新华两座2×0.3kw全固态UHF电视发射设备已运行两年多,目前运行状况良好。全固态电视发射机克服了以往各种发射机难以避免的线性和非线性失真、自激振荡、整机效率低以及电子管寿命短、发射机的运行成本高等缺陷,它使整机效率、技术指标、稳定性和可靠性等方面都得到了提高。但是在日常维护和使用中它有一定的特殊性,因此需要有更加规范的操作和严格的维护管理制度,现就全固态UHF电视发射机维护使用结合自己在实际工作中的经验谈几点看法。
In order to further promote the radio and television “village to village” project of our county and strengthen the radio coverage of rural radio and television programs in central China, in 2007, Tian Peng and Xinhua, two super-solid-state UHF television transmitting devices supporting 2 x 0.3kw Has been in operation for more than two years and is currently in good working condition. All-solid-state television transmitter to overcome the past, a variety of transmitters is difficult to avoid the linear and nonlinear distortion, self-oscillation, low efficiency and short tube life, high cost of the transmitter operating costs, which makes the machine efficiency, technical indicators , Stability and reliability have been improved. However, it has some particularities in the routine maintenance and use. Therefore, more standardized operation and strict maintenance management system are needed. What is the opinion on the maintenance of the all-solid-state UHF television transmitter combined with its own practical experience? .
