Abstract

Способ образования каналов на катоде в несамостоятельном дуговом разряде, в котором между электродами с фиксированным 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 проволочка располагается в отверстии внутри катодной поверхности и касается ее, а при подаче напряжения на разрядный промежуток из точки касания проволочки и катодной поверхности на катоде образуется канал, исходящий из точки касания в направлении от места соединения катода с отрицательным полюсом источника напряжения.The method of forming channels on the cathode in a non-self-sustained arc discharge, in which voltage is applied between the electrodes with a fixed distance between them, the resulting current melts and evaporates a thin wire, which is placed between the electrodes, while the distance between the electrodes is chosen such that the discharge does not spontaneously without a wire ignites, and conditions are created between the electrodes for an avalanche breakdown of the discharge gap, which occurs when there are vapors of an evaporating wire in the air, characterized in that the wire is located in a hole inside the cathode surface and touches it, and when voltage is applied to the discharge gap from the point of contact of the wire and the cathode surface on the cathode, a channel is formed emanating from the point of contact in the direction from the junction of the cathode with the negative pole of the voltage source.

Claims

A method of forming channels on the cathode 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, while the distance between the electrodes is chosen so that the discharge does not spontaneously without wire ignites, 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, which differs it, that the wire is located in a bore inside the cathode surface and touches it, and when a voltage is applied to the discharge gap of the tangency point of the wire and the cathodic surface is formed on the cathode channel emanating from the touch point in a direction from the place of cathode connections with the negative pole of the voltage source.
