GB/T 30846-2014
ActiveHigh-voltage alternating current circuit-breakers with intentionally non-simultaneous pole operation
具有预定极间不同期操作高压交流断路器
Application Summary AI generated
This standard specifies the technical requirements and test methods for high-voltage AC circuit-breakers designed to operate with intentional time delays between the closing or opening of their poles. It is applied in power transmission and distribution systems where controlled sequential pole operation is needed to manage switching transients, such as in capacitor bank switching, reactor switching, or transformer energization. The standard ensures these breakers meet performance and safety criteria under non-simultaneous pole operation conditions.
