小四轮拖拉机上安装的发电机,大多是永磁式单相三路交流飞轮式发电机。该发电机结构简单、维修方便,是小拖理想的供电装置。它的接线方式有两种:一种是三路分别接前后三个灯;另一种是三路连在一起接前后灯。后一种接法的缺点是当有一路内部搭铁或短路时,将产生不发电或电压不足的故障。在农忙或无修理条件时,可采取如下的应急办法:把连接三路的铜片拆去,用三根线分别接出。
Small four-wheel tractors installed on the generator, mostly permanent magnet single-phase three-way AC flywheel generator. The generator has the advantages of simple structure and convenient maintenance and is an ideal power supply device for small tractors. There are two ways to connect it: one is to connect three lights before and after the other three lights respectively; the other one is to connect the lights together before and after the three lights. The disadvantage of the latter connection is that when there is an internal ground or short circuit, there will be no power or voltage failure. In agricultural busy or non-repaired conditions, the following emergency measures can be taken: the three-way copper strip removed, with three separate lines.
