【Abstract】 The breaking capacity is the key performance index of the low voltage circuit breaker. To construct an interruption model of the breaker with numerical method can help to predict the product performance, improve the product design quality and decrease the product cost. However, due to the complexity of the interruption process, there are still many problems unsolved in the field of its mathematic modeling, especially for the modeling of the multi-field coupled phenomenon that exists in the breaker’s interruption process. A comprehensive analysis is given both for the arc mathematical model of the low voltage circuit breaker and for the coupled calculation model during the interruption process, which has certain reference meanings to the comprehensive review of the research progress and status of relevant field and to predict the future development trend.更多还原
