Abstract

The invention discloses an artificial accelerated aging test method aiming at basin-type insulators of a Gas Insulated Switchgear (GIS). The method includes the steps of: aiming at the condition that the basin-type insulators of the GIS frequently break down, combining an aging factor of the basin-type insulators possibly met in the work environment, designing a reasonable artificial accelerated aging test for epoxy resin materials in a laboratory condition; and on this basis, analyzing test data, finding characteristic quantity reflecting the degree of aging, and drawing an insulating-aging characteristic curve of the epoxy resin materials. The artificial accelerated aging test method designs a test platform and an electrode structure in accordance with the aging environment of the basin-type insulators, gives out a determination mode of the temperature and the voltage in the artificial accelerated aging, and ensures the equivalence, the repeatability and the reproducibility of the aging test. The test method of the invention fills the gap of the artificial accelerated aging test method of the epoxy resin in the laboratory condition, and has great guidance significance for solving the aging problem of the basin-type insulators.

Description

technical field [0001] The invention belongs to the technical field of artificial accelerated aging test of solid dielectric, in particular to an artificial accelerated aging test method for GIS pot insulators. Background technique [0002] Gas-insulated metal-enclosed switchgear (GasInsulatedSwitchgear) referred to as GIS, because of its small footprint, high reliability, no pollution, convenient maintenance, long service life and other incomparable advantages compared with many traditional open-type electrical equipment, is widely used at home and abroad. Favored by power users, it has become the most competitive cutting-edge equipment in the power transmission and distribution industry at home and abroad. Basin insulator is the main component of GIS. It has two functions: one is to connect the high-potential parts and the ground potential shell, which plays the role of support and insulation to the ground; the other is to connect the moving contacts and static contacts be...
