ZW32-12/630A column with primary and secondary fusion vacuum circuit breaker dual PT

Product Introduction of 10kV Primary and Secondary Fusion Vacuum Circuit Breaker‌

‌Product Overview‌
The 10kV primary and secondary fusion vacuum circuit breaker is a new generation of intelligent distribution equipment that integrates primary switch (vacuum arc extinguishing) and secondary measurement and control (intelligent protection), designed specifically for the automation upgrade of 10kV distribution networks. This product combines the high breaking capacity of traditional circuit breakers with the data acquisition function of intelligent terminals, and is suitable for scenarios such as substations, industrial and mining enterprises, and new energy grid connection, helping to achieve 'fast fault isolation+remote precise operation and maintenance'.

‌core strengths‌

1. ‌Deep Fusion Architecture‌

• The primary side adopts a vacuum arc extinguishing chamber with a short-circuit breaking capacity of 25kA; the secondary side integrates microcomputer protection and communication modules (supporting IEC 61850) to reduce external wiring and improve reliability.

2. ‌Intelligent Operations‌

• Real time monitoring of current/voltage waveforms and mechanical characteristics (such as opening and closing speed), and uploading them to the distribution automation main station through 4G/fiber optics.

3. ‌flexible configuration‌

• Support customized solutions such as three-stage overcurrent protection and zero sequence protection, suitable for the integration needs of distributed power sources such as photovoltaics and wind power.
