Outdoor Column Electronical Vacuum Circuit Breaker (VCB）
Model：
HZW32-12
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.
  1. Standardized complete set design: Meets the standardized customization requirements of the State Grid for the primary and secondary integration, with consistent installation dimensions and unified interfaces, which can be intercommunicated and interchanged.
  2. Structural features: three-phase independent pillar structure, air insulation, vacuum arc extinction, breaking short-circuit current 20kA up to 30 times.
  3. Modular design: Adopts the modular design concept, and the combination mode of electromagnetic/electronic sensors can be flexibly interchanged.
  4. Autonomous capability: the sensor module has the qualification and independent production capacity, with excellent performance, wide measurement range, high measurement accuracy, and strong reliability.
  5. State monitoring: It supports the collection of analog and state quantities monitoring, remote signaling anti-shake, on-site indication of operating state, communication state, line fault state, etc.
  6. Edge computing: High-performance edge computing to realize on-site analysis of the operating situation.
  7. Protection function: Accurately judge and quickly Isolate short-circuit faults, ground faults, and broken line faults.
  8. Intelligent terminal: It has functions such as line loss collection, feeder automation, communication, positioning, timing and recording, power management, etc., and supports remote maintenance, etc.
  9. High adaptability: Suitable for high-altitude, highly polluted, highly condensed, highly salt spray, and severe cold regions.
