Abstract

The invention relates to a vacuum insulating structure, which especially relates to an insulating structure for impulse voltage effect in the field of vacuum impulse technique. It is characterized in that it arranges a complex film layer between the vacuum impulse voltage of the base insulating material (1) and the vacuum touched surface; the complex film layer is formed by a low second time electron sending factor insulating material film layer (2) and a mental film layer (3), wherein the insulating material film layer (2) is located on the surface of the base insulating material (1); the mental film layer (3) can be embedded into the base insulating material (1) or the insulating material film layer (2). It arranges a transient metal layer (4) between the base insulating material (1) and the insulating material film layer (2).

Description

technical field [0001] The invention belongs to a vacuum insulation structure, in particular to an insulation structure withstanding pulse voltage in the technical field of vacuum pulse power. Background technique [0002] At present, the power in pulsed power technology has reached several terawatts, and the pulse frequency has also reached thousands of hertz. The insulation properties of vacuum-insulated components in pulsed power systems limit the size of the insulation components, system performance and operation. The vacuum surface flashover field strength of materials is generally much smaller than the bulk breakdown field strength and vacuum breakdown field strength, and its vacuum surface flashover characteristics determine the vacuum insulation performance. In the linear acceleration cavity of Dielectric Wall Accelerator and large-scale flash imaging system, due to the requirements of compact structure, low lateral impedance and overall system cost, the vacuum surf...
