在维修汽车直流发电机和调节器中.我们发现逆电流的危害最大.单采用截流器防止逆电流,还存在着一些弊病.例如:人为的调整不当,机械故障等,使闭合电压过低,逆电流过大,触点很快烧坏,有时触点甚至粘结在一起,烧坏发电机和调节器我采用一只2CZ的二极管.串接在调节器电池接柱和电流表之间,并将蓄电池“搭铁”极性改为负“搭铁”(如右图所示).利用二极管单向导电特性,使发电机向蓄电池充电,这样能防止蓄电池的电流向发电机倒放 In the maintenance of automotive DC generators and regulators, we found that the most adverse current adverse effects.Using single-ended device to prevent reverse current, there are still some shortcomings.For example: improper adjustment of man-made, mechanical failure, so that the closing voltage is too low, Reverse current is too large, the contacts quickly burn out, and sometimes the contacts even together, burn out the generator and the regulator I use a 2CZ diode connected in series between the regulator battery post and the ammeter and The battery “ground” polarity to negative “ground” (as shown to the right.) The use of one-way diode conduction characteristics, the generator to the battery charge, so to prevent the battery current to the inverter
