Abstract

A current element motion model of magnetic force

air resistance

thermal buoyancy and Reynolds stress is established on the basis of the chain model of electric arc

in which the interacting force between current elements is considered and the Reynolds equation of the current element in arc movement is introduced. The arc movement process in the gap between the parallel insulator strings of a 500 kV overhead transmission line is simulated with typical parameters

and the results are compared with the test data. It is revealed that the present arc movement model considering the interaction between current elements is more consistent with the actual situation

compared with other models. The larger the inclination angle of the gap electrode is

the greater the magnetic forces of the upper arc root and the arc column become;and longer horizontal electrode is more conducive to the guidance for the arc.
