Abstract

The invention discloses a dielectric gradient material. The dielectric gradient material comprises a matrix material and filler particles, wherein the filler particles are dispersed in the matrix material; the dielectric constant of at least one filler particle is greater than 40; the dielectric gradient material comprises a first region, a second region and a third region located between the first region and the second region; the filler particles are arranged in a chain shape towards the second region in the first region; the filler particles are in unordered distribution in the second region; and the filler particles are in ordered to unordered transition distribution in the third region. The invention also provides an application of the dielectric gradient material. The filler particles in the dielectric gradient material provided by the invention are arranged in the chain shape in the first region, are in unordered distribution in the second region and are in ordered to unordered transition distribution in the third region, so that the dielectric gradient material with the dielectric constant with the gradient is constructed; and the dielectric gradient material has the characteristics of being large in gradient range, wide in application range, excellent in performance and the like.

Description

technical field

[0001] The invention relates to the technical field of insulating material preparation, in particular to a dielectric gradient material and its application. Background technique

[0002] With the development of power systems towards EHV / UHV and large-capacity transmission, and the development of high-tech equipment such as pulse power, high-power microwave, and high-power semiconductor devices towards high voltage and miniaturization, the requirements for electrical insulation performance are becoming increasingly stringent , During the operation of the equipment, the problems caused by the failure of the insulation system, especially the solid insulation, are becoming more and more prominent. It is generally believed that the high non-uniformity of the electric field (local electric field distortion) is the root cause of insulation breakdown and flashover along the surface. At the interface of different media, such as the three junctions of electrodes, insu...
