Description

Устройство состоит из корпуса 1 с метшшйческими пластинами 2 и 3 между парами коро1шрующах игл 4 установлен р д параллельных диэлектрических пластин 5 .(стрелкой показано направление движени The device consists of a body 1 with two plates 3 and 3 between a pair of bore needles 4 and a series of parallel dielectric plates 5 are installed. (The arrow shows the direction of movement

обрабатываемого материала 6).processed material 6).

Устройство работает следующим образом При подаче напр жени  между иглами одного и второго р да зажигаетс  коронный разр д, обеспечивающий возникновение свободных зар дов вблизи канала разрвда. Благодар  введению в конструкцию диэлектрических пластин 5 разр д горит преимущественно между парами электродов из одного и другого р да, ; ;расположенных в промежутке между диэлектрическими пластинами . Таким образом, канал разр да расположен наклонно к направлению движени  материала , и материал обрабатываетс  полосами , ширина которы.х равна рассто нию А (на фиг,. 2 А - проекци  рассто ни  между противосто щими иглами на плоскость, перпендикул рную к направлению движени  материала ) .The device operates as follows. When voltage is applied between the needles of one and the second row, a corona discharge is ignited, which ensures the appearance of free charges near the discharge channel. Due to the introduction of dielectric plates into the design, the 5th discharge burns predominantly between pairs of electrodes from one and the other row; ; located between the dielectric plates. Thus, the discharge channel is inclined to the direction of movement of the material, and the material is processed by strips whose width is equal to the distance A (in FIG. 2A, the projection of the distance between the opposing needles to the plane perpendicular to the direction of movement of the material ).

Поскольку узел между боковыми поверхност ми пластин 5 и плоскост ми, в кото-Since the node between the side surfaces of the plates 5 and the planes in which

рыхрасположены иглы, не превышает 45 , а рассто ние В между иглами в р ду, как правило, меньше рассто ни  между , то А В, и каждый участок материала, iijioходит более чем над одним ка алом разр да , что обеспечивает высокую равномерность обработки материала.needles are not located, does not exceed 45, and the distance B between the needles in the row is usually less than the distance between, then AB, and each piece of material iijio goes over one channel of discharge, which ensures a high uniformity of material processing .
