大同中波台全固态中波发射机驻波比故障浅析

Fault Analysis on the 0-Bit and Bandpass Filter for All Solid-State MW Transmitter Antenna in Datong MW Platform

随着科学技术的发展,中波发射技术也有了快速发展,新一代的DAM 10 k W中波广播发射机为广播发射提供了更加可靠的技术保障,在受到季节、天气变化,维修、维护是否细致到位等因素的影响下,仍会出现一些故障,进而影响其正常运行。为了能够使中波广播发射机的作用得到更大的发挥,使其运行更加高效与稳定,本文研究了DAM 10 k W中波广播发射机的天线零位和带通滤波器故障的成因,原理和解决的方法,旨在加强对天线零位和带通滤波器故障的认识,提高运行维护质量,保证播出的效果。

With the development of science and technology, the medium wave launch technique has also devel- oped rapidly. The new generation of dam lOkW MW broadcast transmitter provides more reliable technical support for broadcasting launch, but it will still have some faults under the influence of the seasons, weather changes, ma- intenance, and then affect its normal operation. In order to be able to make the role of the MW radio transmitter more effective, and make its operation more efficient and stable, this paper studies the cause, principle and solving method on the fault of the antenna O-bit and bandpass filter of the dam lOkW MW broadcast transmitter, so as to strengthen the understanding of the fault of the antenna O-bit and bandpass filter, improve the operation and mainte- nance quality and ensure the broadcasting effectiveness.
