Computer program FLEBUS - calculation of electrodynamic action of currents of short circuit on the flexible busbar of switchgear and air electric lines

Application: designed for dynamic analysis of flexible conductors of switchgear and air electric lines when two-phase or three-phase short circuit.

Advantages: the calculation takes into account: the height difference of the suspension and other features of the geometry of the span; suspended garlands of insulators; the stiffness of the supporting and insulating structures; splitting of phase – in-phase and phase-to-phase spacers; the action of ice and wind loads; elastic and thermal elongation of the conductors; the characteristics of short circuit.

Key features: in the course of processing are determined: load on the wires and garlands insulators; the efforts of the busbar and tap switcher on the portals and devices; the deviation of portals and devices under the action of applied forces; motion trajectory of busbars at any point of the span; minimum distances be­tween conductors of adjacent phases, and also between assembled busbars and taps and the maximum de­viation of busbars; the heating of the conductors during short circuit; current of electrodynamic span stability.
