在维修实践中,广大的维修人员习惯用万用表来判断电容的好坏与优劣,这种方法虽然简单易行,但对电容的容量有一定的要求,当电容容量较小时,用这种方法就很难凑效了。在这里介绍一种用高阻耳机来判断电容好坏的方法,这种方法可以很容易地对小容量电容的开路、短路以及漏电等故障 In maintenance practice, the majority of maintenance personnel used multimeter to judge the quality of the capacitor and the advantages and disadvantages, although this method is simple, but the capacity of the capacitor has certain requirements, when the capacitor capacity is small, this method It is difficult to work together. Here is a high-impedance headphones to judge the method of good or bad capacitance, this method can easily open a small capacity capacitor, short circuit and leakage fault
