Research on CAD/CAE Parametric Modeling of Circuit Breaker Based on Multi-feature Information

The circuit breaker is the key control device for the power transmission system. With the improvement of its complexity and the shortening of its development cycle, the traditional interactive modeling method in CAD/CAE is difficult to meet the requirements of the development and design of the circuit breakers. Based on the theory of FEA information model, the modeling method of multi-feature information parameterization is proposed by abstracting, classifying and analyzing the information of the CAD/CAE model for the circuit breaker in this paper. Taking a high-voltage spring circuit breaker as the research object, the CAD/CAE modeling information and modeling process which are reused and fasted parametric modeling are realized. The research results show that the method can meet the modeling and development for the circuit breaker which has a complex structure and multi-performance, has a high efficiency of simulation analysis, and can provide the systematic and efficient support in the area of information and technique for the circuit breaker designers.
