Product Introduction

Product Introduction:

The primary-secondary integrated pole-mounted circuit breaker can be used in various scenarios such as segmentation, branching, interconnection, and demarcation of 10kV lines. It utilizes transformers (or AC sensors) to collect electrical quantities such as voltage and current from the lines, monitors the operating status of the distribution lines, and employs automation devices or systems to promptly detect line faults, accurately diagnose fault sections, isolate the fault sections, and quickly restore power supply to non-fault sections, thereby effectively improving line power supply reliability.

Product Features:

  1. High Protection Level

Fully sealed and insulated design with an IP65 protection rating, meeting anti-condensation requirements. Aviation connectors use military-grade components, ensuring an extremely high protection level.

  1. High Fault Detection Accuracy

Equipped with voltage and current transformers (sensors) and an energy metering module, it calculates active power, reactive power, power factor, frequency, and energy. Through multi-criteria fusion algorithms, it achieves rapid fault identification and isolation, ensuring line safety.
