Embodiment Construction

[0027] The core idea of ​​the present invention is: (1) The cross-section of the three-plate transmission line is "I"-shaped, which is essentially a parallel connection of three currently commonly used three-plate transmission lines, so its characteristic impedance is reduced by 1 / 3. (2) Dozens of cable insertion holes are symmetrically arranged at the grooves on both sides of the I-shaped three-plate transmission line, and the pre-stage discharge unit can be connected through the cable to realize the convergence of multiple pulse currents. (3) Along the electric pulse transmission direction, the cross-sectional size of the transmission line gradually decreases to realize the pulse transmission and convergence from the large-scale primary pulse power system to the small-scale load, that is, the compression of the energy and power spatial scale. (4) Multiple I-shaped three-plate transmission lines are used in series to increase the output voltage. (5) Multiple I-shaped transmis...

Abstract

The invention relates to a radial three-plate transmission line for transmitting and converging pulse current, which comprises an inner electrode, an outer electrode and multiple cable plug holes. The section, vertical to a power transmission direction, of the radial three-plate transmission line is defined as a cross section; both the outer electrode and the inner electrode have I -shaped cross sections; the outer electrode is provide with an I -shaped cavity matched with the inner electrode in shape and size; the inner electrode is embedded in the outer electrode along the transmission direction, and a gap is left between the inner electrode and the outer electrode; and the gap between inner electrode and the outer electrode is filled with deionized water as an insulating medium. The cross section of the three-plate transmission line is I-shaped, which is parallel connection of three common flat plate transmission lines essentially, the characteristic impedance is thus reduced by 1 / 3, and thus, the adjustment is flexible, and the use is convenient.

Description

technical field [0001] The invention belongs to the field of high-power pulse transmission, and relates to a three-plate pulse transmission line, which is used to realize the radial transmission and spatial convergence of dozens of high-power pulses and large currents, and has important applications in large-scale pulse power devices such as Z-pinch. Background technique [0002] Ultra-high power pulse technology is an important means to obtain extreme physical experiment conditions such as extreme high temperature, high pressure, high energy density and strong radiation in the laboratory. important application. High-power pulse technology compresses energy on a time scale to obtain ultra-high peak power in a very short time; on the other hand, it transmits and concentrates energy on a spatial scale to obtain ultra-high power density in an extremely small size. Pulse time scale compression is usually achieved by using energy storage devices (such as capacitors, forming line...
