| Abstract: | In air circuit-breakers electronic tripping control system,tripping force of a flux converter has direct impacts on the reliability of circuit-breakers tripping-off. Via analysis to flux converter tripping force,optimum design for tripping force was carried out. Under the conditions of unchanged tripping force in circuit-breakers,safe and reliable tripping-off of air circuit-breakers was realized,so as to make the tripping system miniaturized and solve the reliable problem of the mechanism interaction. |
