摘要： PROBLEM TO BE SOLVED: To provide a vacuum valve, capable of reducing local input of heat to a contact, reducing an electrode melting at a zero point of current and of improving the cutting performance. SOLUTION: A first coil electrode 33 made of the conductive material (such as pure copper) and for generating a magnetic field in parallel with an arc and a second coil electrode 34 made of the material, of which resistance value is increased with increase of the electrifying current, and for generating a magnetic field in an opposite direction are provided in rear of an electrode 32 having a contact 31. With increase of the current, intensity of the synthetic magnetic field by these coil electrodes 33, 34 per unit current is increased, and range of a point, in which the minimum arc voltage is detected, is widened in the peripheral area from the center of the electrode. With this structure, arc concentration position can be moved, and the local input of heat to the contact can be lowered.
