Research on Intelligent Integrated Grounding Arc Suppression System
In view of such shortcomings as incpmplete arc suppression and low low accuracy of line selection of arc suppression coil
an integrated grounding arc suppression system and products
which combines an arc compression coil with active arc extinguishing of the faulted phase via a small reactor
are developed. The arc extinguishing technology and the line selection method of the active grounding through the small reactance are innovated by analyzing and studying the changing characteristics of the electric quantity of the zero-sequence loop of the single-phase grounding system.It is proved by simulation and full-scale grounding test of 10 kV integrated grounding arc suppression system that the product has such technical advantages as reliable arc suppression performance at full frequency
and the accuracy of line selection is more than 99%.
