For obtaining the internal temperature distribution of the assembled shunt capacitor under the operation condition of 1.2 times rate voltage and ambient temperature of 55 ℃

in this paper

finite volume method is used and the assembled shunt capacitor BAMH126.3/3

1/2

-80000-1 W is taken as study object

the simulation model of 3D temperature filed is set up to simulate its temperature distribution as per the actual size of capacitor and by the use of hydromechanics simulation software Fluent. The overall internal temperature filed distribution is obtained. It is shown by the simulation result that the internal temperature of the assembled shunt capacitor is on the rise from bottom to the top and the te

mperature at the hottest point is inside the core of the top.The highest point of the transformer oil temperature is on the top of radiator and the lowest point at the bottom of the radiator

which provide reference for the optimization design of the capacitor radiator structure and control of the hottest point of internal temperature of the assembled shunt capacitor.
