dcterms:description
The heating of electric equipment represents limits for safe operation. The current path must be designed care-fully, especially when the cooling is realised by natural convection. Thus a CFD calculation and final temperature measurements are considerable aspects of every design. The paper is focused on two modelling methods used for calculation of spatial temperature distribution along the current path of a 1250A disconnector. The first one presented is a thermal network method which uses similarity between electric and thermal circuits, though more detailed results were achieved using the CFD analysis. It allows detailed view on natural convection and reveals most problematic parts of the electric equipment. The heating of electric equipment represents limits for safe operation.
