磁联轴器抗干扰原理及其应用

An Anti-magnetic Principle for Magnetic Coupling and Application

本文首先将磁联轴器的漏磁效应简化为等效磁偶极子，然后定性地分析了磁联轴器干扰 的起因和特点，提出了相应的抗干扰措施和方法，并将其应用于干式水表防磁设计问题中，实践 证明本文提出的方法是行之有效的．

In this paper, we simulated the effect of leakage magnetic field in magnitic coup- ling by an equivalent magnetic dipole, discussed the interference sources and properties of the coupling qualitively, and proposed the associated anti-interference tachnique used fOr the design of dry water meter developed in recent years. The experiment shows that the method suggested is effecient.
