视频信号传输一般采用直接调制技术、以基带频率(约8MHz带宽)的形式,最常用的传输介质是同轴电缆。同轴电缆是专门设计用来传输视频信号的,其频率损失、图像失真、图像衰减的幅度都比较小,能很好的完成传送视频信号的任务。
下面一一解释这个名词的含义:1开关。开关是指在电路正常的工作条件或过载工作条件下能接通、承载和分断电流、也能在短路等规定的非正常条件下承载电流一定时间的机械开关电器。2隔离器。具有隔离功能的电器称为隔离器,它不具备接通断开负荷电流的功能,相当于以前的隔离开关。隔离器具有以下特点:断开触头之间距离应该可见或能明显表示“闭合”和“断开”状态;隔离器应能防止意外闭合;应有防止意外断开隔离电器的锁定措施。以下电器可以作为隔离电器:隔离器、隔离开关、隔离插头;插座与插头;连接片;熔断器;具有隔离功能的开关和断路器;不需要拆除导线的特殊端子。
绝缘材料:高密度聚乙烯。绝缘单线:在导线上连续挤制绝缘材料,采用规定的10种标准色谱以便识别,并保证电缆的电气性能。绝缘线对:将绝缘单线按规定的色谱、不同的节距均匀地绞合成线对。缆芯结构:绝缘单线绞合成对后采用同芯式或单位式绞合成缆芯,各单位采用不同的扎纱,以便施工、维护识别。
在架空安装时需要用吊线支承。在一30~C一60~C的环境条件下,电缆的机械和电气性能均保持不变。结构:导线:退火裸铜线,铜线直径为0.40,0.50,0.60,0.70,0.80,0.90mm。绝缘材料:高密度聚乙烯、中密度聚乙烯或聚丙烯,绝缘线的颜色符合全色谱标准。
