Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The coaxial spiral reentrant pulse forming line structure includes three parts: the reentrant forming line section 1 , the main switch section 2 and the load section 3 . The reentrant forming line segment 1 is composed of forming line outer cylinder 12, middle cylinder 11, spiral inner cylinder 10, rear end cover 13 and insulating filling medium. The spiral inner cylinder 10 has a uniform caliber, adopts thin-diameter wires to be helically wound with multiple starting ends, adjacent wires are insulated, and the winding pitch is uniform. The outer surface of the middle cylinder 11 is a straight cylinder, and the inner surface is a stepped cylinder with different calibers. The three conductor cylinders, the wire outer cylinder 12, the middle cylinder 11, and the spiral inner cylinder 10, are approximately equal in length and gradually decreasing in diameter, an...

Abstract

The invention belongs to the technical field of pulse power, relates to a coaxial spiral re-entry pulse forming line and aims at solving a problem that the coaxial spiral re-entry pulse forming line adopts a multistage re-entry structure to realize a complicated structure under multiple pulse widths. The coaxial spiral re-entry pulse forming line comprises three parts including a re-entry forming line segment, a main switch segment and a load segment, wherein the re-entry forming line segment comprises three coaxially nested conductor cylinders, namely an outer cylinder, a middle cylinder with a stepped inner surface and a spiral inner cylinder, and two pulse forming lines (an outer line and a non-uniform spiral re-entry line) are formed, wherein the non-uniform spiral re-entry line includes a plurality of spiral line sections. The coaxial spiral re-entry pulse forming line has the beneficial effects that the multiple-pulse-width output is realized through the spiral re-entry structure, and the coaxial spiral re-entry pulse forming line is simple in structure and easy to realize.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and relates to a coaxial spiral reentrant pulse forming line. Background technique [0002] A pulse forming line with a reentrant structure (patent application number: 201510473606.1) uses three coaxial conductor cylinders to form two pulse forming lines, the outer line and the inner line. The electrical length of the outer line and the inner line (that is, the time of electromagnetic wave transmission) Equal, the wave impedance is equal, the inner line is the reentrant structure of the outer line, the outer line is used for energy storage, the inner line does not store energy, the initial energy formed in the line during the discharge process is completely released after two fluctuation cycles (one of the fluctuation cycles is the traditional single The pulse width formed by the coaxial line or the Blumlein line), so as to realize twice the pulse width output. [0003] The coaxial two-stage...
