Study on the Dynamic Modeling of a MCCB Mechanism Including Electro-Magnetic Force Effect

전자기력의 영향을 포함한 MCCB 기구부의 동역학적 모델링 방법 연구

  • Published : 2001.03.01

Abstract

To design a limiting MCCB (Molded Case Circuit Breaker) mechanism, a dynamic modeling of the mechanism in which the electro-magnetic force effects are incorporated needs to be developed. Conventionally, electro-magnetic effects were considered separately for the design of the mechanism. In this paper, an electro-magnetic force that is induced by limited current is identified and included in the dynamic modeling of the mechanism. Thus, the electro-magnetic which is defined as a external force and the mechanical effects are simultaneously considered for the design of the mechanism which is composed of contactor, spring , link, latch and so on.
