ZW32-12KQ Outdoor Vacuum Circuit Breaker Overview:
Driven by a “complete fusion” philosophy, this Outdoor Vacuum Circuit Breaker brings the ubiquitous power Internet of Things (IoT) directly into the circuit breaker industry by introducing mature 4G network connectivity for real-time operational control. It creatively integrates remote measurement, remote signaling, remote control, and remote inspection directly into the controller, endowing the equipment with AI intelligence.
- Intelligent Interconnection: Combines IoT and big data to complete fault detection and reporting in real-time, effectively reducing power failure durations.
- Synchronized Operations: A simple drive mechanism paired with an innovative fast algorithm provides the hardware and software foundation necessary for precise voltage synchronous closing.
- Climate Control: Features a built-in temperature compensation system that automatically heats the battery when ambient temperatures drop below 0°C.
- Remote Management: Comes with a dedicated APP on a handheld operating tablet utilizing automatic connection and password input control.
Key Features of the Outdoor Vacuum Circuit Breaker:
Every Outdoor Vacuum Circuit Breaker in this series undergoes a full-time design process where the FTU, electronic sensors, mechanisms, and breakers adopt a full life cycle scheme to drastically enhance overall stability.
- Extreme Speed: The pure high-voltage electromagnetic drive mechanism acts directly on the circuit breaker contacts, which, combined with a fast fault algorithm, pushes opening and closing speeds to the extreme. Fault detection occurs in 2.64ms, and complete fault isolation takes only 11.68ms.
- Simplified Reliability: The direct-acting simple mechanism reduces the number of components from over 100 to more than 40 by eliminating the crank arm mechanism and operational friction.
- Proven Durability: The operating mechanism has successfully run over 100,000 times in laboratory testing without a single failure.
- Advanced Sensors: Utilizes 12 ring-shaped ceramic high-voltage capacitors (expandable to 15) for stable sampling and power extraction across harsh environments.
Outdoor Vacuum Circuit Breaker Operating Conditions:
Built strictly for demanding environmental applications, the ZW32-12KQ Outdoor Vacuum Circuit Breaker operates dependably under the following conditions:
- Ambient Air Temperature: -40°C to +70°C (Daily temperature difference of 25°C).
