摘要A;500 kV 0400 kA 0100 ns脉冲功率发生器~ PPG-I！X箍缩实验装置是在清华大学设计和建造的。它由马克思发生器、组合脉冲形成线PFL！该装置采用了一种新颖的线路设计，即四条阻抗为5V的水线并联构成一条1.25V的组合式功率线，并在一条匹配的1.25V传输线上通过一个公共的自断V0 N开关将它们结合在一起。在PFL的峰值充电电压下，V0 N开关在多路放电模式下击穿，电能通过1.25V传输线馈入测试负载。本文介绍了PPG-Ⅰ型脉冲发生器的设计与测试。关键词：多通道放电;脉冲形成线;脉冲功率;上升时间; X箍缩1.在脉冲功率发生器的输出电极之间，两个或两个以上的导线在一个点交叉接触，构成一个“x”形负载。交叉位置首先爆炸，然后轴向收缩，形成所谓的x-收缩等离子体，通过磁压力脉冲发电机向“x”线提供合适的电流~Kalantar H Shelkovenko
Abstract A;500 kV0400 kA0100 ns pulsed power generator~PPG-I! for x-pinch experiments was designed and constructed atTsinghua University. It is composed of a Marx generator, a combined pulse forming line~PFL!, a gas-filled V0N fielddistortion switch, a transfer line, and a copper-sulphate resistive load for testing.The PPG-I implements a novel designin lines that four pieces of waterline with impedance 5V in parallel constitute a combined PFL with 1.25V, andincorporate each other by a common self-break V0N switch on a matched 1.25V transfer line. At the peak chargingvoltage of the PFL, the V0N switch breaks down in multi-channel discharge mode, and electric energy is fed into thetesting load through the 1.25V transfer line. This article presents the design and test of the PPG-I generator. Keywords: Multi-channel discharge; Pulse forming line; Pulsed power; Rise time; X-pinch 1. INTRODUCTION Between the output electrodes of a pulsed power generator,two or more wires crossing and touching at a single pointconstitute an “x” shape load. The cross position explodesfirst and then pinches axially to form the so-called x-pinchplasma,bythemagneticpressureaspulsedpowergeneratordelivers a suitable current to the “x” wires ~Kalantar H Shelkovenko
