The Research of a New Arc Suppression Coil

摘要：

According to the neutral point of arc extinction coil grounding system cant very well compensated the permanent earthing failure of current shortcomings , a kind of new arc extinction coil was designed. When the power failed, the microcomputer controled the fine-tuning of the arc extinction coil and paralleled into the coarse arc suppression coil,Adjusting the fine-tuning arc suppression coil, and made the whole arc extinction coil all work in the full compensation state, thus effectively extinguished the electric arc.Through the matlab Simulations, We tested the maximum measurement error of the detuning degree is 0.64%, the earth capacitance and capacitance current of the maximum error is no more than 1%, and it can effectively extinguish more than 85% of the instantaneous electric arc.
