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.

Peculiarity

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.
Structural features: three-phase independent pillar structure, air insulation, vacuum arc extinction, breaking short-circuit current 20kA up to 30 times.
Modular design: Adopts the modular design concept, and the combination mode of electromagnetic/electronic sensors can be flexibly interchanged.
Autonomous capability: the sensor module has the qualification and independent production capacity, with excellent performance, wide measurement range, high measurement accuracy, and strong reliability.
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.
Edge computing: High-performance edge computing to realize on-site analysis of the operating situation.
Protection function: Accurately judge and quickly Isolate short-circuit faults, ground faults, and broken line faults.
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.
High adaptability: Suitable for high-altitude, highly polluted, highly condensed, highly salt spray, and severe cold regions.
