Research and Experiment on Improving Current Carrying Capacity of AC Contactor
In order to meet the demand for miniaturization of electrical equipment and solve the problem of temperature rise exceeding the standard after the current carrying capacity of AC contactors was increased,a feasible approach to improve the current carrying capacity of contactors was selected by analyzing the main factors affecting the temperature rise and contact resistance of AC contactors.Taking a certain type of AC contactor as the object,the contact material,contact type,contact pressure,etc.were optimized.The feasibility of the optimization scheme was verified through the theoretical calculation,and the effectiveness of the scheme was finally verified through experiments.
