Mechanism for truncating power-frequency continuation and reburning by means of a super-strong arc-extinguishing gas
Source abstract
Abstract
The process of arc suppression with a super-strong arc-extinguishing gas (AEG) includes arc truncation and reburning suppression. In this paper, the plasma mechanics, the mechanics of the super-strong AEG, and the arc-reburning suppression by the AEG are all modeled. Combined with test data, the characteristics of arc truncation, pressure characteristics, and time characteristics of the AEG are analyzed, and the law of medium recovery and reignition suppression of arc fracture under the action of the super-strong AEG are discussed. The test results show that with a super-strong AEG, the arc-extinguishing threshold and time are 40 kA and less than 0.5 ms, respectively.
