Rolled strip pulse forming line based on high energy storage density liquid medium

Abstract

The invention discloses a rolled strip pulse forming line based on a high energy storage density liquid medium, which is designed to solve the problems of small output pulse width, large volume and weight, irrecoverability after breakdown, etc. The invention comprises the high energy storage density liquid medium, metal strips, a retaining plate, and an insulation encapsulation part. The metal strips are in the slots of the retaining plate. The retaining plate is in the insulation encapsulation part. The high energy density liquid medium is poured into the insulation encapsulation part, which surrounds all the metal strips and fills the entire inner space of the insulation encapsulation part. The metal strips are consisted of three swirly convoluted metal strips. The shape of the slots of the retaining plate is swirl lines. In the invention, long conductor length is obtained in a small geometric space with excellent electromagnetic shielding being guaranteed. The energy density is increased. Moreover, the pulse width of the output quasi square wave pulse is increased effectively. Besides, the device is easy to build and maintain with low cost. The invention is appropriate for a high voltage electrical pulse generating system.

Description

technical field [0001] The invention relates to a pulse forming line in the technical field of high-power pulse drive sources, in particular to a coiled strip-shaped pulse forming line based on a liquid medium with high energy storage density. Background technique [0002] The high-power pulse drive source stores energy at a lower power, and releases the energy to the load in a short period of time through switching, pulse modulation and other technologies, so as to obtain a high-power electrical pulse with a specific waveform on the load. In recent years, driven by the application requirements of high-performance pulse-driven source devices, quasi-square wave high-power electric pulses have been used in high-power microwaves, high-energy pulsed lasers, dielectric barrier discharges, shock wave generators, material surface modification, and industrial waste gas and wastewater treatment. Many fields such as biomedicine, food sterilization and disinfection have received extens...

Problems solved by technology

[0014] The technical problem to be solved by the present invention is to solve the problems of the existing pulse forming line such as the small output electric pulse width, large volume and weight, and unrecoverable breakdown due to the low internal conductor geometry and low dielectric constant of the energy storage medium. Provide a new type of coiled ribbon pulse forming line based on high energy storage density liquid medium. This pulse forming line adopts a coiled inner conductor, which can make reasonable use of space and obtain a large electrical length in a small space ; At the same time, using a liquid medium with a higher dielectric constant as the energy storage medium can not only further increase the electrical pulse width, but also has breakdown recovery and is convenient for device maintenance
