Изобретение относитс к луговым генераторам низкотемпературной плазмы, в частности к способу контрол режима их работы в процессе эксплуатации.The invention relates to meadow generators of low-temperature plasma, in particular to a method of controlling the mode of their operation during operation.
Известный способ контрол работы плазмотрона с межэлектродной вставкой путем определени положени рабочего торца эрозпрующего стержневого электрода сложен и неточен.The known method of controlling the operation of a plasma torch with an interelectrode insert by determining the position of the working end of an eruptive rod electrode is complex and inaccurate.
Изобретение отличаетс от известного тем, что с целью упрощени эксплуатации положение электрода контролируют по величине напр жени между ним и межэлектродной вставкой.The invention differs from the known one in that in order to simplify operation, the position of the electrode is controlled by the magnitude of the voltage between it and the inter-electrode insert.
Изобретение по сн етс чертежом.The invention is illustrated in the drawing.
Плазмотрон содержит полый внешний электрод 1, стержневой расходуемый электрод 2, изолированную от них межэлектродную вставку 3, изол тор 4, источник питани 5, электроизмерительное устройство 6, исполнительный механизм 7.The plasma torch contains a hollow external electrode 1, a rod consumable electrode 2, an inter-electrode insert 3 insulated from them, an insulator 4, a power source 5, an electrical measuring device 6, an actuator 7.
Принцип действи предложенного способа следующий.The principle of operation of the proposed method is as follows.
В зазор между электродами подают плазмообразующий газ. Известными способами возбуждают дуговой разр д между электродами плазмотрона. За счет образовани пространственного разр да межэлектродна вставка приобретает электрический потенциал.Plasma gas is fed into the gap between the electrodes. The arc discharge between the plasmatron electrodes is excited by known methods. By creating a spatial discharge, the interelectrode insert acquires an electrical potential.
По мере сгорани торца стержневого электрода измен етс положение пространственного разр да относительно межэлектродной вставки, что приводит к изменению ее потенциала . Проградуировав шкалу измерительного устройства 6 в единицах длины х электрода 2 от его рабочего торца до плоскости, в которой расположена межэлектродна вставка 3, по показани м устройства 6 можно определить местоположение рабочего торца стержневого электрода 2. Подава сигнал на исполнительный механизм 7, можно регулировать положение эрозирующего электрода.As the end of the rod electrode burns, the position of the spatial discharge relative to the electrode insert changes, which leads to a change in its potential. By graduating the scale of the measuring device 6 in units of length x of the electrode 2 from its working end to the plane in which the interelectrode insert 3 is located, the position of the working end of the rod electrode 2 can be determined by the indications of device 6. electrode.
Предмет изобретени Subject invention
Способ контрол режима работы плазмотрона с межэлектродной вставкой, например коаксиального , путем определени положени рабочего торца эрозирующего стержневого электрода , отличающийс тем, что, с целью упрощени эксплуатации, положение указанного электрода контролируют по величине напр жени между гим и межэлектродной вставкой.A method of controlling the operating mode of the plasma torch with an inter-electrode insert, for example coaxial, by determining the position of the working end of the eroding rod electrode, characterized in that, in order to simplify operation, the position of the specified electrode is controlled by the magnitude of the voltage between the electrode and the inter-electrode insert.
