2.工作原理
电流通过电线时,将会以电线为中心而产生同心圆形状的磁场。此时,如果将电线弯成如图中的“弹簧形”,电感器内部的磁通量将指向同一方向,从而增强。通过调整圈数,可以产生与圈数成正比的磁场。这就是电感器的原理。
电流通过电感器会产生磁场,相反,磁场变化则会产生电流。
(电磁感应定律)
E = L ・(d i/d t)
L: 电感器的自感
E: 反电动势
电感器的原理
电感器中产生的反电动势E,与单位时间的电流变化率(di/dt)成正比,因此在一定电流持续沿同一方向流动的直流电通过时不会发生。也就是说,电感器对于直流电流没有任何作用,只对交流电起到阻碍电流的作用。利用电感器的这一性质,在交流电路中可以用作电阻(阻抗)。电感器具备的阻抗Z(单位Ω)为:
Z=ωL=2πfL
f为交流频率、L为电感器的自感。
3.符号与单位
(1)电感符号:L
(2)电感单位:亨 (H)、毫亨(mH)、微亨 (uH),1H=103mH=106uH。
(3)电感量的标称:直标式、色环标式、无标式
(4)电感方向性:无方向
(5)检查电感好坏方法:用电感测量仪测量其电感量;用万用表测量其通断,理想的电感电阻很小,近乎为零。
