在汽车电器修理中,常遇到一些电子器件在同一车上连续损坏多只的现象,例如,在一辆汽车上,发动机调节器因损坏而更换后只能工作几天,再更换后还是只能工作几天。这是什么原因造成的?经仔细研究后认为,这些电子器件的损坏是某些电感元件产生的正向瞬变过电压造成的。本文就这一问题进行讨论,相信它对于帮助驾驶员和维修人员能迅速、准确地找到故障原因和排除故障,具有一定的现实意义。
In the automotive repair, often encountered some electronic devices in the same car continuous damage more than just the phenomenon, for example, in a car, the engine regulator damaged due to replace only a few days after the replacement or only Can work for a few days. What caused this? After careful study that the damage of these electronic devices is caused by certain inductive components of the forward transient over-voltage caused. This article discusses this issue, I believe it to help drivers and maintenance personnel quickly and accurately find the cause of the malfunction and troubleshooting, with some practical significance.
