Název v původním jazyce
The effect of an electromagnetic shielding on the forces acting among the conductors of three-phase lines
Popis výsledku v původním jazyce
When designing rotating electrical machines, transformers and other electrical equipment for high power, it is necessary to resist the forces between the conductors which big currents. The paper deal with the magnetic shielding, which can reduce these forces. It is presented a mathematical model of the magnetic field in the area of three parallel conductors of three-phase supply. Based on the numerical solution is determined the Lorentz force per unit length of conductors. Following is presented a calculation of eddy current losses in the shielding jacket. The computational algorithm is illustrated with numerical examples. The general rules are established for a reliable design of shielding.
