摘要
仪表本身内部单元电路彼此之间以磁场现象、光电效应等手段实现相互之间无电的直接联系,称为仪表的隔离特性。本文利用这一特性,分析了电Ⅲ型仪表在集中使用中出现信号传递故障的原因,以及解决故障的方法。
Meter's insulating property refers to the direct non-electrical linkage between the inner unit circuits of a meter, realized by the means of magnetic field or photoemission.This paper has analyzed the causes of signal transmission failure in using DDZ-Ⅲ Meter,and then presented some methods of solving this kind of teehnical problem.
