在检修波兰产波罗乃兹轿车电系时,不慎将并联在交流发电机上的蓄电池线碰落,当交流发电机高速运转时,电压调节器失控,导致石英电子钟损坏。笔者在无石英电子钟原理图的情况下,采用对比的方法,拿一只故障钟与一只完好的钟进行比较,测试元器件的参数,并按照实物绘出其电路原理图(附图),供修理时分析参考。 In the repair of Polish Polonazi car electrical system, accidentally parallel in the alternator battery line down, when the alternator high-speed operation, the voltage regulator out of control, resulting in quartz electronic clock damage. The author in the absence of quartz electronic clock schematic diagram of the situation, using a comparative method, take a fault clock and a good clock to compare the parameters of components, and draw the circuit diagram in kind (with photos) , For analysis and reference for repair.
