The ZW68 outdoor high-voltage AC vacuum circuit breaker is a new generation of primary and secondary deep fusion intelligent automated vacuum circuit breaker developed to meet the needs of rapidly developing smart distribution networks for terminal switchgear. In addition to complying with standards GB1984, DL402, and relevant provisions of the International Electrotechnical Commission IEC 62271-100, it also meets the State Grid Corporation of China material procurement standard—General Technical Specification for 12kV～24kV Outdoor Pole-Mounted Circuit Breakers.
Main Functions
- The terminal can automatically detect line voltage, phase current, zero-sequence current, and zero-sequence voltage, with functions for automatic fault identification, proactive fault information upload, and fault SOE recording. It can record fault occurrence time, fault nature (grounding or short-circuit fault), switch action information, current value at the time of fault, etc., with fault clearing time not exceeding 100ms.
- The terminal has a unique and prominent on-site fault display function, facilitating fault investigation.
- Optional local ground wireless maintenance and program upgrade, no need for pole climbing, convenient and safe maintenance.
- The terminal has a reliable power supply system, supporting access to batteries, supercapacitors, lithium batteries, etc., with real-time power monitoring, online battery management, and battery charge-discharge protection functions. When the battery voltage falls below the discharge cutoff point, it can automatically cut off the backup power supply.
