A pulse formation line body is formed by coiling two pole plates and two medium layers in an Archimedes spiral manner, the high-voltage pole plate, inner-side insulating media, the low-voltage pole plate and outer-side insulating media are arranged successively from inside to outside, and the positions of the high-voltage pole plate and the low-voltage pole plate can be interchanged; and the high-voltage pole plate, inner-side insulating media, low-voltage pole plate and outer-side insulating media are coiled for n rounds in the Archimedes spiral manner, the first round of the high-voltage pole plate and the first round of the low-voltage pole plate are led out in the axial two sides via a high-voltage leading-out foil and a low-voltage leading-out foil respectively, and the pulse formation line composed of an axial leading-out structure and n-a rounds of complete band-shaped wires is formed. The coiling pulse formation line is high in quality of output waveforms, and is simpler in structure compared with a three-pole-plate coiling band-shaped line.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and relates to a winding pulse forming line drawn from a bipolar plate axially. Background technique [0002] The pulse forming line is the main technical unit for generating high-voltage pulses in the field of pulse power technology, and the miniaturization of the pulse forming line is an important research direction in the field of pulse power technology. The dielectric film has high working voltage and high energy storage density. The pulse forming line using the dielectric film as the energy storage medium has the characteristics of small volume and compact structure. Among them, the winding strip line based on the multilayer dielectric film has a three-electrode structure. Its high-voltage electrodes are wrapped between two inner and outer low-voltage electrodes, so the winding electromagnetic leakage is less, and the output waveform quality is high.

Problems solved by technology

But it still has some problems. On the one hand, the coiled strip line has two low-voltage electrodes, so the electrode leads are difficult to handle, the lead-out connections have large inductance, and the connection is a weak link in the insulation.

The national defense patent (ZL201428002698.1) proposes a coaxial lead-out film medium winding stripline structure, which connects the winding stripline to a coaxial electrode, which can convert the energy of the stripline angular transmission into a coaxial Directional transmission overcomes the problem of large lead-out inductance of the strip line, but the volume and weight of the coaxial electrode itself is relatively large, resulting in a relatively low energy storage density of the entire forming line, which is not conducive to further reducing the volume and weight of the forming line

The paper (Influence of winding method on the output characteristics of wound strip pulse forming line) introduces a wound strip line structure based on two polar plates, which is wound by two polar plates and two layers of insulating medium. One end of the bipolar plate is output, which simplifies the three-electrode winding stripline to a certain extent. The disadvantages are: first, the structure itself does not constitute a complete stripline structure, and cannot generate ideal square waves; second , which is a single-point lead-out. If it is lead out from the same side, it will be difficult to insulate, and if it is lead out from both sides, the lead-out inductance will be large.

Therefore, the quality of its output waveform needs to be improved
