经我们维修和保养的交流发电机每年数量不下百余只,而损坏较为严重的机件多为发电机的定手线圈,其故障率高达90％左右,究其原因,认为有以下几种情况: 一是使用人员对交流发电机认识不够,总感觉比直流发电机“娇气”,在发电机出现不充电、充电电流小或充电不稳时,不能及时找出故障的原回予以排除,而是盲目地调整发电机皮带的紧度,此时充电量稍有好转,但其皮带紧度远远超过标准量,使发电机旋转平面严重错位。
The number of alternators repaired and maintained by us is not less than 100 per annum and most of the more damaged ones are stationary coils of generators with a failure rate as high as 90%. The reasons for this are as follows: : First, users do not know enough about the alternator, the total feel than the DC generator “delicate”, the generator appears no charge, charging current is small or unstable charging, can not find out the original fault to be ruled out, and Is blindly adjust the tightness of the generator belt, then charge a slight improvement, but the tightness of the belt far exceeds the standard amount, so that the generator rotation plane serious dislocation.
