下面举集电极调幅电路为例。是集电极调幅电路,由高频载波振荡器产生的等幅载波经T1加到晶体管基极。低频调制信号则通过T3耦合到集电极中。CCC3是高频旁路电容,RR2是偏置电阻。集电极的LC并联回路谐振在载波频率上。如果把三极管的静态工作点选在特性曲线的弯曲部分,三极管就是一个非线性器件。因为晶体管的集电极电流是随着调制电压变化的,所以集电极中的2个信号就因非线性作用而实现了调幅。由于LC谐振回路是调谐在载波的基频上,因此在T2的次级就可得到调幅波输出。

  A类阻燃性能优于C类阻燃性能。使用特点额定电压U0/U为450/750V。电缆导体的长期允许工作温度为70℃。电缆的敷设温度不低于0℃。推荐的允许弯曲半径无铠装层的电缆,应不小于电缆外径的6倍。有铠装、铜带屏蔽结构的电缆,应不小于电缆外径的12倍。

  矿用电缆选择矿井供电系统中,高压供电线路一般都采用铠装电缆,其故障率相对低压供电所采用的[1]要少得多。采区供电是供电系统中的薄弱环节,工作环境又较差,因而如何选择电缆的型号与截面,关系到供电运行的安全。
