摘要
广播电视发射台站利用卫星广播来接收电视信号是常用手段之一。但雪衰一直困扰广电人,因雪衰导致的卫星接收系统瘫痪事例比比皆是。对此,介绍利用贴膜式电加热融冰除雪系统来降低或消除雪衰对卫星传输信号的影响。该系统不影响天线正常运作,除雪响应及时、除雪彻底、可持续作业、效率高,能够降低维护成本。
One of the commonly used methods for broadcasting and television transmission stations is to use satellite broadcasting to receive television signals.However,the decline in snow has always troubled radio and television personnel,and there are numerous cases of satellite reception system paralysis caused by snow decline.This article introduces the use of a film mounted electric heating ice melting and snow removal system to reduce or eliminate the impact of snow attenuation on satellite transmission signals.This system does not affect the normal operation of the antenna,with timely and thorough snow removal response,sustainable operation,high efficiency,and can reduce maintenance costs.
