Název v původním jazyce

Forces acting on the shielded three-phase supply

Popis výsledku v původním jazyce

Mechanical forces impact three-phase line conducted by large currents. These forces cause higher safety requirements. This paper deals with possibilities of lowering these forces by shielding of the conductors. The numerical method of calculation of thetime function of forces, when conductors are shielded by ferromagnetic jackets and conducted by symmetrical three-phase system currents, is stated. The calculation of eddy currents density induced into shielding jackets is stated further; eddy currents cause the heating of shielding jackets. An illustrative example shows that properly designed shielding is able to strongly reduce the magnitude of forces while the eddy current losses density is very low is the heating is subtle.
