Разработка методики исследования влияния Ð²Ð½ÐµÑˆÐ½Ð¸Ñ ÑÐºÑ€Ð°Ð½Ð¾Ð² на распределение тока в псевдоискровом разряднике

Abstract

В работе спроектирована и реализована упрощенная физическая модель для исследования влияния проводящих экранов на растекание тока в псевдоискровом разряднике. Высоковольтная установка состоит из нескольких компонентов: источник питания (генератор импульсов тока), ошиновка генератора, разрядная камера. Ошиновка генератора, состоящая из гибких проводников и медной трубы, имеет возможность изменять режимы токоподвода. В изготовленной разрядной камере реализован способ пространственной регистрации канала разряда с помощью секционированного электрода. Импульсная установка была выполнена с соблюдением критерия подобия по амплитуде перемещения дуги в процессе разряда. В результате проведенного расчета, был выбран диапазон рабочего давления 10-70 мм рт. ст. с учетом того, что за характерное время разряд успевает переместиться из центра прибора к его периферии. Поддерживая давление постоянным 15 мм рт. ст, проведены серии экспериментов для различных конфигураций токоподвода с использованием экрана и без него. Из измеренных осциллограмм тока в секциях был получено распределение суммарного разряда по секциям электрода. Проведена обработка полученных экспериментальных данных и на ее основании были сделаны соответствующие выводы.

Was design and construct simplifiedphysical model to researching of conductiveelectromagnetic screeninfluenceon current spreading in pseudospark switch. The high-voltage plant compose with several component: power source(surge current generator), busbar generator, discharge chamber. Busbargenerator, consisting of flexiblewire and copper tube, have possibility to change variant of shunt. In produced discharge chamber was realized spatial locality method for finding plasma channel by using segmented electrode. The pulse installation was construct with similarity criterionobservance associated with arc movement amplitude in time of discharge. On the basis ofcalculation, was chosen pressure range10-70 mm Hg, take into consideration of the charge burn pending the plasma channel have time to move from centre of switch to periphery. For the constantvalue pressure was carry out experimental series for different shunt configuration with using screen and without it. On the ground the currentoscillogram measuring was calculated summary charge distribution to segmented electrode. Was taken experimental data processing and was made based conclusion.
