The heat build-up of tap-off units of busbar trunking system in relationship to their surfacing.
Forejtník, Jan ; Radil, Lukáš (referee) ; Foral, Štěpán (advisor)
This study is dedicated to the effect of surface modification on lid warming of busbar trunking system BD2 which is manufactured by Siemens company in Mohelnice town (CZ). By using experimental methods, it investigates heat transfer by radiation and natural convection. It evaluates which type of surface modification is more effective by transfer heat. This study uses a method of emisivity comparison and a procedure given in standards for heat up test afterwards. It led to recognition, that various colour shades used on busbar system have similar high emissivity. Smooth colour spraying transfers heat a bit more effectively than rough colour spraying. Outputs of supplementary measurements give basis for numerical simulations in SolidWorks software. Numerical analysis assists to interpret results, for example by sensitivity study of heat transfer depending on emissivity.
