Description

technical field [0001] The invention belongs to the technical field of power equipment aging test, and in particular relates to a GIS solid insulation multi-sample three-factor aging test device and a test method. Background technique [0002] The solid insulation of gas-insulated combined electrical appliances (GIS) is an important component to ensure its reliability, and it is usually made of polymer-based composite insulation materials. During the operation of the equipment, GIS solid insulation will be affected by factors such as electricity, heat, and force, and its performance will deteriorate, which will affect the reliability of the entire GIS and even the power system. Especially in recent years, the voltage level has been continuously improved, which puts forward higher requirements for the reliability of GIS solid insulation. Therefore, the state evaluation and life evaluation of GIS solid insulation are very important. [0003] However, in general, polymer-base...
