Direct-current arc influence factor analysis device, method, equipment and medium

The invention provides a direct-current arc influence factor analysis device, method and equipment and a medium. The device comprises an electrode control module, an anode vessel, a wire and a power supply. The electrode control module is used for controlling an electrode to approach an anode vessel to generate a direct-current arc, the anode vessel is connected with a power supply through a wire, the information acquisition module is used for acquiring arc form, arc current, arc voltage and magnetic field information of the direct-current arc, and the arc analysis module is used for receiving the information acquired by the information acquisition module. The influence direction and the numerical influence level of the direct-current arc influence factors on the direct-current arc are determined based on the collected information, and the device and the method are provided for effectively and quantitatively analyzing the interference influence of different influence factors on the direct-current arc. 本发明提供一种
