Description

technical field [0001] The invention relates to an automatic modeling and analysis method for the overvoltage level of a switching reactor of a vacuum circuit breaker, belonging to the technical field of high-voltage power transmission and transformation. Background technique [0002] At present, vacuum circuit breakers are widely used for their strong arc extinguishing ability, but because of their strong arc extinguishing ability, it will cause overvoltage when extinguishing arcs. The main load of vacuum circuit breakers There are inductive equipment and capacitive equipment, and the breaking overvoltage is mainly the interception and re-ignition of the vacuum arc of the circuit breaker. On the one hand, when the vacuum circuit breaker breaks the inductive small current, the inductive device stores energy when the arc is extinguished, which can oscillate at the load end or convert it into an overvoltage on the capacitance to the ground; on the other hand, the heavy arc dur...
