| titleOfInvention | A kind of hand arc welding machine three-phase electric power open phase detection method and device |
| abstract | The invention provides a kind of hand arc welding machine three-phase electric power open phase detection method and device, the method is applied to the hand arc welding machine three-phase electric power open phase checkout gear comprising power transformer, any two-phase in described power transformer coupling three phase mains, with thinking that hand arc welding machine three-phase electric power open phase checkout gear is powered; Described method comprises: detect feedback current; According to the feedback current detected, judging three-phase electricity whether phase shortage, without the need to arranging multiple step-down transformer and lack detection circuit, simplifying circuit structure, cost-saving. |
