碳膜电位器为人们常用的电子元器件之一,所谓碳膜电位器是在马蹄形的纸胶板上涂上一层碳膜制成的,其阻值变化和中间触头位置的关系有直线式、对数式和指数式三种。然而任何电位器使用时间久了都会出现一些故障及问题,所以下面小编为大家介绍一些有关碳膜电位器的会出现的故障以及检测方法:

 

碳膜电位器

碳膜电位器

  1.故障分析

  (1)碳膜电位器因过电流而严重烧坏故障:这时碳膜电位器烧成开路。调节音量时扬声器中会出现“咯吱”“咯吱”的响声,停止转动碳膜电位器时噪声便随之消失,这说明音量电位器出现转动噪声大的故障。

  (2)碳膜电位器内部引脚断路故障:这时音量电位器所在电路不能正常工作,对于碳膜电位器而言,可能出现无声故障,或者出现音量关不死的情况。

  (3)碳膜电位器转动噪声大:主要出现在音量电位器中,因为音量电位器经常转动。一般音量电位器或音调电位器使用一段时回见后或多或少也会出现转动噪声大的故障,这要要是由于动片触点月碳膜之间摩擦,造成碳膜损坏,使动片与碳膜之间接触不良。

  2.检测方法

  2.1阻值测量方法

  碳膜电位器的阻值测量分为在路测量和脱开测量。由于一般电位器的引脚用引线与电路板上的电路相连,焊下引线比较方便,故障用脱开测量的方法,这样测量的结果够准确说明问题。

  (1)测量两固定引脚之间的阻值。其阻值应等于该电位器外壳上的标称阻值,远大于或远小于标称阻值都说明碳膜电位器有问题。

  (2)检测阻值的变化情况。用万用表欧姆档相应量程,一支表棒搭动片,另一支表棒搭定片,缓慢的左右旋转碳膜电位器的转柄,指针指示的阻值应从零到较大值,再从较大值到零连续变化。指针偏转也应是连续的,即不应该出现指针跳动的现象。

  2.2试听检测方法

  这种方法主要用于音量电位器和音调电位器的噪声故障检测。让电路处于工作状态,然后左右旋转碳膜电位器转柄,让动片触点在碳膜上滑动。转动时如果扬声器中有“咯吱”“咯吱”声音,则碳膜电位器有转动噪声大的故障,反之,如果没有噪声,说明碳膜电位器是基本良好的。

  3.清洗方法

  碳膜电位器较大的故障是转动噪声大,通过清洗处理可以修理好,具体方法是:折法让纯酒精清洗液流到电位器内部的碳膜上,不断转动转柄,是使触点在碳膜上滑动,达到清洗碳膜和触点的目的。这种清洗可以在通电的情况下进行。在这里需要注意的是,一定要用纯酒精。然后转动转柄,试听噪声大小,指导其噪声消失为止。
