摘要
确保信号源的安全,是广播电视安全播出的重要基础之一。对于接收卫星信号来说,降雪对信号安全有严重的威胁。本文较详细的介绍了浙江广播电视传输发射中心北高峰发射台对卫星天线自动融雪系统的思考和实践。对于有类似情况的高山发射台具有一定的借鉴和参考价值。
To ensure the safety of signal source is one of the important bases tbr safety broadcasting. For receiving satellite signals, snowfall is a serious threat to signal security. This paper introduces the thought and practice of automatic snow melting system of satellite antenna in Zhejiang Radio and Television Transmission Center and Beigaofeng Launch Station. This paper is a certain reference for the mountain launch station with similar situation.
