摘　　要：极化磁系统广泛应用于磁保持继电器和极化继电器,其永磁体工作点与气隙工作点的确定是极化磁系统分析与设计的基础。利用等效磁路中磁压模型的节点分析法,通过列写节点磁压方程,对几种典型的差动式和桥式极化磁系统的永磁体工作点和气隙磁通进行了理论分析与计算,并给出了永磁工作点的图解分析法,总结出统一的可用于计算机编程的计算公式,所得结果有助于各种极化磁系统的设计、计算以及进一步分析极化磁系统的工作机理。Polarized magnetic system is applied in the fields of magnetic keeping relay and polarized relay. The work points for permanent magnet and gap are the base of analysis and design for polarized magnetic system. In this paper, the work points of the permanent magnet and air magnetic flux for the typical polarized systems of differential and bridge magnetic system are analyzed and calculated based on the equivalent magnetic voltage model circuit equations. The graphic method for work points of the permanent magnet is given. The uniform calculating expressions are also sum up. The conclusions are useful to design, calculate and analyze the working mechanism of polarity magnetic system.
