A series of multi - pulse experiments are performed at breakdown voltage up to 400kv , peak current up to 30ka with an interval of 5ms , which shows spark gap switch could be obtained good insulation recovery in several milliseconds under the condition of water dielectric pulse power modulator with low load 在擊穿電壓400kv ,峰值電流30ka ,脈寬40ns的工作參數(shù)下,采用吹氣的辦法(氣流速度30m / s ) ,使氣體火花開關多脈沖運行間隔達到5ms ,實驗結果與理論估計相符。
The technology of alternating - current - boosting by way of constant current is successfully used to charge capacitors with 25 kilojoules of energy in only eight seconds . rail - gap switch with performances of long life and highly steady state are designed . and the high voltage pulse generator , which can produce low - excursion and fast - rise pulses , are designed by using double trigger circuit and hydro - thyristor as switch 在大功率恒流充電技術上,成功的應用了交流調壓式恒流技術,可以在8s內讓電容器儲存25kj的能量;設計出了長壽命、高穩(wěn)定的軌道開關;采用氫閘流管做開關,使用雙觸發(fā)電路,研制出了低抖動、快前沿的高壓脈沖發(fā)生器(點火機) ;采用單片機和pld ,研制出了精度為10ns的延時同步機。
Water dielectric pulse power modulator has been widely applied because of its merits of high energy storage density , compactness , and capability to drive low impedance high power microwave sources . research for multi - pulse operation of high power spark gap switch with high current and comprehending its physical properties are the basis to study multi - pulse operation or repetitive operation of water dielectric pulse power modulator 水介質脈沖功率調制器具有儲能密度高,結構緊湊、與低阻抗微波源較好匹配的特點,因此得到廣泛的應用,但是受到高功率、大電流氣體開關的絕緣恢復的影響,水介質等低阻抗脈沖功率調制器的重復頻率運行或多脈沖運行受到較大的限制。
