Overview：
The outdoor Column Electronical vacuum circuit breaker ZW32 electronic sensor zero-sequence directional feeder terminal can realize the local feeder automation functions without relying on the distribution automation master station and communication. Through short-circuit / grounding fault detection technology, no-voltage breaking, fault path adaptive delay incoming call to close, and other control logic, it can adapt to the multi-branch and multi-link distribution network structure, realize on-site line selection, regional positioning, and isolation of single-phase ground faults, and realize isolation of the fault area and restoration of power supply in the non-fault area through re-closing.
