徒弟:在前面师傅已分析检修了在稳压控制电路中因取样电容漏电而引起的自动关机故障,有一定收获。希望继续举几种典型例子,分析检修由其他原因所造成的自动关机故障好吗? 师傅:好的,现举两种故障部位相同(都处在控制电路与开关管之间耦合电路)而不同元件(一是电容,二是电感)变值所造成的自动关机故障为例,其故障现象、电路特点和检修方法分述如下。
Apprentice: In front of the master has analyzed and repaired in the voltage regulator control circuit due to leakage of sampling capacitors caused by automatic shutdown failure, there is a certain harvest. Would like to continue to mention a few typical examples, analysis of maintenance by other reasons caused by automatic shutdown fault? Master: Well, now the same fault in both parts of the site (both in the control circuit and switch between the coupling circuit) and different Components (a capacitor, the second is the inductance) caused by the automatic shutdown of the fault as an example, the breakdown of the circuit characteristics and maintenance methods are described below.
