对于一个具有电阻、电感、电容的交流电路中,交流电源两端的电压一般不和它输出的电流同相位。如果调节电路的参数或者电源频率使它们同相位,这时电路就发生了谐振现象。按照发生谐振现象的电路不同,可以分为串联谐振和并联谐振。串联谐振在R、L、C串联电路中,但满足感抗XL等于容抗XC时,即电源的输出电压和输出电流同相位,就会发生谐振现象。因为发生串联电路中,所以也称为串联谐振。为了更加深入了解串联谐振的现象,在matlab/simulink中搭建交流串联R、L、C电路。

带有四组辅助触点的接触器看一下这个接触器的辅助触点是没有标注的,如果我们学会了前一个接触器常开常闭编号的规律,就能一眼看出来。线圈电压不同选购接触器的时候还要注意线圈的工作电压,同样大小的两个接触器,线圈电压有可能不同哦。万用表测量接触器的好坏,首先要测量接触器的线圈,接触器的线圈的电阻大多都是几百欧姆。接触器的功率越大,吸合力越大,电流也就越大,对应的线圈电阻也就越小。如果万用表测的线圈的电阻是无穷大,那么线圈肯定开路了,如果测的线圈的电阻是0,那内部肯定短路了。
