| dc.description.abstract | Air is a desirable alternative to SF6 in medium voltage (MV) switchgear. However, the thermal properties of air is poorer compared with SF6, and this paper presents a first step in the process of finding an optimized thermal design. Mapping of the resistances and the thermal condition have been performed on a custom made prototype. Together with CFD-simulations, these methods are found to be useful for gaining insight and improving the thermal design of MV switchgear. The combined contact resistances (bolted and others) was for found to constitute about 35 % of the total resistance of the prototype. Possible contributions from the skin-effect and/or iron losses seem to be of little or no influence to the power input. | |
