Abstract

Temperature rise is one of the important examination indices of GIS equipment. Excessive temperature rise will lead to serious heating of the equipment

which will affect the reliability of GIS operation. In order to accurately analyze the heating and temperature rise of GIS

based on finite element analysis software and thermoelectric coupling method

the solution model of loss heating of 800 kV GIS disconnector is established. The temperature field distribution of disconnector is calculated and analyzed on the basis of considering various factors such as different heat dissipation coefficient of conductor and enclosure

environmental temperature and material resistivity varying with temperature. Finally

through the temperature rise test

the accuracy of the method is proved by comparing the calculated values of the temperature rise of the main parts with that of the experimental values

which provides a reference for the design of the disconnector.
