Influence of the Ventilation Apertures on Low Voltage Switchboard Heating
Abstract:
The paper presents a computer model, developed in the software programme Comsol, for studying the influence of the ventilation apertures on low voltage (LV) switchboard heating. Results have been obtained, concerning the distribution of the LV switchboard thermal field and air velocity field in cases of closed LV switchboards and switchboards with ventilation apertures both at natural and forced ventilation. The influence of the ventilation apertures location, as well as of the air velocity at forced ventilation, on heating the current carrying circuits in the LV switchboard has been studied.
