Long-term heating and excessive temperature rise will significantly affect the electrical and insulation performance of electric power equipment, causing the potential security risk. In this paper, the temperature rise situation under normal operation of a 12-kV medium voltage switchgear is studied through modeling and simulation method. First, in the simulation analysis of the whole switchgear, based...
The temperature rise is very critical for the normal operation of switchgear, in which eddy current and contact resistance are the two important influence factors. In this paper, firstly, the main conductive circuit model of one kind of 12kV medium voltage switchgear is established using commercial software Solidworks. Secondly, the effect of the eddy current and contact resistance on the temperature...
