摘要：The life expectancy of an AC contactor is adversely affected by electrical arcs and heat rise within the contactor. Electrical arcing results in erosion in the contact material and also results in failures due to welding. To find alternative methods of improving contactor life expectancy and reduce the maximum temperature without adding costs to production, a computer model was created for the contactor using MATLAB and Simulink that simulated the dynamics of the contactor at closing. The model solves equations that use geometries and material properties to estimate contact life and heat generation. The results from the simulation can be used to run a Design of Experiments analysis to find which combinations improve life and reduce maximum temperature without adding significant costs.
