模拟焊接电弧负载控制器的研制

Development of the Controller for the Welding Arc Duty Simulator

分析了采用模拟焊接电弧负载测试弧焊电源外特性和动特性的可行性 ;确定了模拟电弧负载用电阻的制作材料、结构形式 ;明确了模拟电弧负载电阻值的变化规律并研制了实现该阻值变化规律的控制器。

The feasibility of measuring the external characteristic and dynamic characteristic of arc welding power source using the welding arc duty simualtor is analyzed. The material characteristic and construction of the resistances used for welding arc duty simulator is defined. The regular pattern of the resistance of the welding arc duty simulator is designed. And a controller is developed to control the change of resistances.
