摘要
Abstract
The arc-extinguish model after current peak was established by equivalent circuit and equations.And the arc-extinguish time after current peak was studied in the different time constant and expected short-circuit current in combination with some test data from the DC 1 500 V prototypes. The result shows that at the same time constant and within a certain range, the greater the expected short-circuit current is, the shorter the arc-extinguish time after current peak becomes; and at the same expected short-circuit current, the lower the time constant is and the higher the arc voltage is, the shorter the arc-extinguish time becomes.关键词
