Description

technical field [0001] The invention belongs to the field of surface charge measurement of solid dielectric materials, in particular to an automatic measurement device for surface charge of dielectric materials based on a two-axis slide table. Background technique [0002] Polymer dielectric materials are widely used in power equipment, and their insulation properties are directly related to whether the equipment can operate safely and stably. In the insulation system composed of polymer dielectric insulating materials, after a certain voltage is applied and a partial discharge occurs, charges will accumulate on the surface of the dielectric and stay for a long time. The surface charge will not only distort the original electric field of the insulation system, but also promote the next discharge when the external electric field is reversed, resulting in a decrease in the dielectric insulation performance. A large number of polymer insulation materials are used in modern ind...
