Problems solved by technology

When the pulse forming line is filled with high-voltage insulating gas or transformer oil, the ratio of the output pulse width to the length of the pulse forming line is 6.7ns / m and 10ns / m respectively. If it is required to output a high-voltage pulse with a pulse width of 100ns, pulse forming is required. The line lengths are 10m and 15m respectively, the system is huge and the project is very difficult

Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with specific implementation examples.

[0019] see figure 1 — figure 2 , the present invention includes a reentrant pulse forming line segment 5 , a switch segment 6 and a load segment 7 .

[0020] The reentrant forming line segment 5 is composed of three metal cylinders and an insulating filling medium. The three coaxial metal cylinders include an outer cylinder 10, a middle cylinder 11 and an inner cylinder 12. The three metal cylinders are nested together The integrated coaxial structure, the left end of the outer cylinder 10 and the rear cover 8 are electrically connected through the flange, the right end of the outer cylinder 10 and the left end of the switch outer cylinder 15 are electrically connected through the flange, and the left end of the middle cylinder 11 is in electrical contact with the left end of the inner cylinder 12 Connected or directly integrated pr...

Abstract

The invention belongs to the technical field of pulse power, and relates to a pulse forming line with a reentrant structure, the purpose of which is to reduce the axial length of the pulse forming line. The invention includes three parts: a reentrant forming line segment, a switch segment and a load segment. The three coaxial cylinders that re-enter to form a line segment and the insulating medium constitute two pulse forming lines, that is, the electrical length of the outer line and the inner line are equal, the wave impedance is equal, and the matching impedance of the load is the sum of the impedance of the outer line and the inner line. The beneficial effects of the invention are: under the condition of the same axial length, the output pulse width of the pulse forming line with reentrant structure is twice that of the traditional pulse forming line.

Description

technical field [0001] The invention belongs to the technical field of pulse power and relates to a pulse forming line with a reentrant structure. Under the condition of the same length, the output pulse width can reach twice that of the traditional pulse forming line. Background technique [0002] Pulse power technology is an emerging science and technology that studies the storage of energy for a relatively long period of time, and then quickly compresses, converts, and finally releases it to the load. The research object is that the voltage is between 10 4 ~10 7 V, current 10 3 ~10 7 Amps, pulse width 10 -5 ~10 -10 seconds, pulse power greater than 10 6 Generation and application of high power pulses in W. [0003] In a pulse power device, if you want to obtain a high-voltage pulse with a fast front and a flat top, you generally need to use a pulse forming line. According to the different structural forms, there are coaxial lines, strip lines, etc. The length is pr...
