  可靠接地时整个485线路的地线必须要有良好的接触,从而保证电压一致,因为在实际施工中,为了接线方便,将线剪成多段再连接,但是没有将屏蔽线作良好的连接,从而使得其地线分成了多段,电压不能保持一致,导致共模干扰。

  本安信号控制电缆主要是应用于防爆的场合。主要方法就是限制设备的工作电流在一定的程度之下,这样就不会引起火花导致baozha。订货时需注明即可。②本安信号控制电缆的屏蔽型式为:铝塑复合膜屏蔽和镀锡丝屏蔽。

串联型稳压电路有放大和负反馈作用的串联型稳压电路是常用的稳压电路。它的电路和框图见图4。它是从取样电路(R3、R4)中检测出输出电压的变动,与基准电压(VZ)比较并经放大器(VT2)放大后加到调整管(VT1)上,使调整管两端的电压随着变化。如果输出电压下降,就使调整管管压降也降低,于是输出电压被提升;如果输出电压上升,就使调整管管压降也上升,于是输出电压被压低,结果就使输出电压基本不变。在这个电路的基础上发展成很多变型电路或增加一些辅助电路,如用复合管作调整管,输出电压可调的电路,用运算放大器作比较放大的电路,以及增加辅助电源和过流保护电路等。

作为电工,我们对“接地”这个词儿很熟悉,但还有一个“重复接地”,那么什么是重复接地呢?重复接地又有什么好处呢?如下:中的RS就是重复接地。定义:在中性点直接接地系统中,除了工作接地以外,其他点的再次接地。图A中RN为工作接地,RS为重复接地。主要作用:避免零线断开或接触不良时电击的危害性。如中,没有重复接地,当零线断开时,如果设备漏电,金属外壳带电,人触及金属外壳,人体通过大地和工作接地构成回路,就会触电。
