The models of resources and manufacturing processes, which aim at the production system of the resin dry transformers, are constructed by Object-oriented Petri Net (OPN) in this paper. SCB9 1000/10 400(Cu) transformer is taken as case study, the flow chart of manufacturing transformers are described at first, and then researched by static analysis, dynamic analysis and integrated application in details. The conflicts of the OPN models, which may happen in all manufacturing system of resin dry transfers, have been resolved. The whole manufacturing system are improved and optimized in the manufacture processes at last.
