Simulation Analysis of the Electrical Connector for Severe Accident Based on the ABAQUS Program
In order to study the thermal effect of the instantaneous high temperature,which generated by hydrogen combustion on the 1E electrical connector of the PWR NPP during severe accident conditions,the ABAQUS finite element simulation software was used to conduct thermal simulation analysis of the 1E electrical connector in the hydrogen combustion environment of certain PWR NPP.The study obtained the temperature field diagram of the electrical connector and the temperature curve at the sealing ring.According to the simulation results,the high temperature test of the sealing ring has verified that the 1E electrical connector can withstand the high temperature environment of the hydrogen combustion under severe accident conditions,and successfully passed the severe accident hydrogen combustion test.Which greatly shortening the product development cycle,reduce the initial investment(2 million yuan RMB)and provide analytical guidance for product analysis and selection.It has certain reference value for the design and material selection of similar electrical connectors and other electrical equipment in severe accident environments of nuclear power plants.
