Proteus是电路仿真软件,就是搭建一个电子电路模拟实际的硬件电路,这样就不需要真正的硬件,我们就可以在仿真电路中关联Keil编译好的程序,来验证我们的代码。这样的好处是只要有电脑我们就可以编程并验证,但是仿真电路是理想化的硬件,真正的硬件和仿真之间还是有很大区别的,尤其是高频电路和模拟信号,因此仿真电路刚开始可以用一下,还是要买一块单片机开发板作为实际硬件来学习。单片机的学习我理解是是入门简单,深入有难度。

不信可以拆开自己家已经接好的开关,用电笔测一下——理论上来讲,当开关关闭时,只有火线接线柱能够点亮电笔。但是实际使用时,接了零线(灯线)的接线柱十有八九也可以点亮电笔。只不过大部分开关,即使零线带电,所带的电压也比较低,不足以在线路中产生电流。但如果绝缘性再差一点,产生的电流稍大了,就会给电容充电。还有一点:开关上带指示灯的时候,关灯时指示灯会亮起,此时需要产生微弱电流——这部分电流会流经电容,并被电容储存起来。

  电力电缆得到越来越广的应用。1911年,德国敷设成60千伏高压电缆,开始了高压电缆的发展。1913年,德国人M.霍希施泰特研制成分相屏蔽电缆,改善了电缆内部电厂分布,消除了绝缘表面的正切应力,成为电力电缆发展中的里程碑。
