Direct-Current Forced Interruption and Breaking Performance of Spiral-Type Contacts in Aero Applications

Direct-Current Forced Interruption and Breaking Performance of Spiral-Type Contacts in Aero Applications

This paper analyses the transient characteristics and breaking performance of direct-current (DC) forced-interruption vacuum interrupters in 270 V power-supply systems. Three stages are identified in forced interruption: the DC-arcing stage, current-commutation stage, and voltage-recovery stage. Dur...
