摘要

本文的目的是强调在不同类型的电压下，在发散电场存在的情况下，浸泡在流体中的绝缘子上的放电传播机制中电容现象的参与。研究了由不同材料和不同流体（液体和气体）制成的绝缘体。证明了界面两组分的相对介电常数和绝缘体厚度在传播机制中的作用。当绝缘子厚度减小和/或绝缘子或液体的相对介电常数增大时，径向放电的长度和分支数增加。

Highlighting Capacitive Phenomena in the Discharges Propagation on the Insulators Surface Immersed in Fluids

The aim of this article is to highlight the involvement of capacitive phenomena in the mechanisms of discharge propagation on the insulators immersed in fluid, in the presence of a divergent electric field, under different types of voltages. Insulators issued from different materials and different fluids (liquids and gases) are investigated. The role of the relative dielectric permittivities (dielectric constants) of both constituents of the interface and the thickness of the insulator in the propagation mechanisms is demonstrated. The length of radial discharges and the number of their branches increase when the thickness of the insulator reduces and/or the relative dielectric permittivity of the insulator or that of liquid increases.
