Abstract

The invention discloses a memory, and a basin-type insulator thermodynamic model construction method, device and equipment. The method comprises the steps of obtaining attribute parameters of a basin-type insulator; logically dividing the body structure of the basin-type insulator into a central conductor part and an epoxy resin insulating part; further logically dividing the epoxy resin insulation part into a plurality of annular insulator parts; determining a plurality of heat sources according to the logic division result of the body structure of the basin-type insulator, wherein the heat source comprises a main heat source arranged at the central conductor part, a plurality of first auxiliary heat sources arranged at the convection boundary of the SF6 gas and epoxy resin insulation part, and a second auxiliary heat source arranged at the position where the GIS shell conducts heat to the basin-type insulator; and according to the attribute parameters and the heat source, constructing a thermodynamic model of the basin-type insulator through a finite element method. According to the method, the air chambers on the two sides of the basin-type insulator do not need to be modeled, and the thermodynamic simulation result of the basin-type insulator with good accuracy is obtained on the premise that a large amount of calculation workload is saved.

Description

technical field [0001] The invention relates to the field of electrical engineering, in particular to a method, equipment and device for constructing a thermodynamic model of a storage device and a basin type insulator. Background technique [0002] Gas Insulated Switchgear (GIS) has the advantages of small footprint, low failure probability, high safety performance, small environmental impact, easy installation and maintenance, etc., which can greatly improve the reliability of power supply. However, the fully enclosed structure of GIS makes it difficult to detect minor faults such as abnormal heating and partial discharge inside, which will lead to malignant accidents such as insulation breakdown. [0003] Basin insulator is an extremely important insulating part in GIS equipment. It is used to support and fix the high-voltage current conductor in GIS, so as to insulate it from the shell and the ground, so as to ensure the safe and stable operation of the equipment. There...
