When the data is transmitted at a high speed, the transmission line effect appears. At this point, the characteristic impedance of the load must match the output, otherwise, the echo will reflect and cannot work normally. Even though in some cases, can be done by resistance in the end of the parallel matching impedance matching, but in the long run, when the resistance change and come back down for some reason, besides, the disadvantages of this also leads to increased power consumption.

,二次回路分部分来看。一般的电路图都会在图纸的右侧或者下侧标明相应的回路是做什么的,或者具有什么作用。这个时候分部分来看,将控制回路分开为:保护电路,测量电路,控制电路等部分来看,有助于快速的把握原理。4,快速看图需要把握线号。线号。正规电路图中,任何一条线,任何一个接线端子都是有线号的,线号就是导线的名字,同样的线号就是同样的分支和作用。快速从线号切入看复杂的电路图也是一个好方法。5,重要:电路原理+经验储备。

  它的含卤量约为含卤阻燃电缆的1/3左右。发烟量也接近于公认的“低烟”水平。根据《电线电缆燃烧试验方法》的规定,采用成束燃烧试验方法考核的阻燃电缆分为A、B、C3类,其中A类电缆试验条件苛刻,性能较B、C类更优,价格也贵。

  在使用RS485接口时,对于特定的传输线路,从RS485接口到负载其数据信号传输所允许的大电缆长度与信号传输的波特率成反比,这个长度数据主要是受信号失真及噪声等影响所影响。理论上,通信速率在100Kbps及以下时,RS485的长传输距离可达1200米,但在实际应用中传输的距离也因芯片及电缆的传输特性而所差异。

企业维修电工,因为必须要与动力电路接触,所以三角形电路,Y形电路为必知电路。首先,了解一下什么是三角形电路,以电动机电路为例,所谓的三角形电路,就是电动机内部引出的六个线端首位相连,组成的三个端点用来接三相电源的接线模式。注意,这里只有三相三线,没有中性线。再来说说Y形电路,它比三角形简单,它就是简单的把三个端点连接到一起,然后留下的另外三个端点用来接三相电源线的电路。他是有一根中性线,所以是三相四线。
