Abstract
Способ локального нагрева участка поверхности катода в несамостоятельном дуговом разряде, в котором между электродами с фиксированном расстоянием между ними подается напряжение, возникающий ток плавит и испаряет тонкую проволочку, которая размещается между электродами, при этом расстояние между электродами выбирается таким, при котором разряд самопроизвольно без проволочки не зажигается, а между электродами создаются условия для лавинного пробоя разрядного промежутка, возникающего при наличии в воздухе паров испаряющейся проволочки, отличающийся тем, что участок вокруг контакта проволочки и поверхности катода окружается диэлектриком, а при подаче напряжения на участке поверхности катода, ограниченном диэлектриком, концентрируется энергия, локально разогревающая этот участок поверхности катода. A method for locally heating a portion of the cathode surface in a non-self-contained arc discharge, in which a voltage is applied between the electrodes with a fixed distance between them, the resulting current melts and evaporates a thin wire that is placed between the electrodes, and the distance between the electrodes is selected so that the discharge spontaneously without wire it doesn’t ignite, and conditions are created between the electrodes for avalanche breakdown of the discharge gap arising in the presence of vapor of an evaporating wire in the air and characterized in that the area around the contact surface of the wire and the cathode is surrounded by an insulator, and when a voltage is applied to the cathode surface portion bounded by dielectric energy is concentrated locally warming up this portion of the cathode surface.
