摘　　要：塑壳断路器(MCCB)在配电线路中起着重要的保护、控制和调节作用。塑壳断路器操作机构的运动特性是影响断路器分断性能的关键,其中弹簧参数的设计至关重要。采用有限元方法结合解析法计算了触头受到的洛伦兹力和霍尔姆力,获得电动斥力和触头终压力,进而设计了相匹配的触头弹簧和主拉力弹簧,可为工程中弹簧的设计提供方法。Molded case circuit breaker （ MCCB） plays an important role in the protection, control and adjustment of the power distribution lines. Motion characteristics of MCCB operating mechanism is the key to the performance of breaker,and the spring parameters design is of prime importance. Finite element method combining with analytic method was used to calculate the Lorentz force and Holm force of contact,then the electric repulsion and contact pressure could be solved, to design the matching of the contact spring and main tension spring, which provides a method for design of spring in the engineering.
