一二次融合成套柱上断路器

Primary and Secondary Integrated Pole Mounted Circuit Breaker

The primary and secondary integrated pole mounted circuit breaker is the core of comprehensive fault disposal and self-healing of overhead lines, and is also the key equipment for the current standardization, lean and intelligent construction of distribution networks. The product incorporates new and effective short circuit and ground fault algorithms, and combines advanced Internet of Things communication technology, end sensing technology, edge computing technology, etc., which can improve the intelligent sensin and control capability, integration decision-making level and reliable power supply level of the distribution network, and provide safe and reliable digital solutions for the construction of the new type of electric power system.

Core Function

  • The products of one and two times fusion column circuit breaker have the characteristics of safety and reliability, robustness and durability, standardization and universal interchangeability.
  • Pole mounted circuit breaker ZW32-12 type adopts the structural form of vacuum arc extinguishing and air insulation, with the integrated design of insulation part, external high-precision current-voltage combined sensor, adapting to the standardized configuration of different transformer types, and the installation dimensions of the shell and connecting terminals refer to the standardized design requirements.
  • Standardized feeder terminal FTU is equipped with single-phase ground fault identification function for small current grounding system, which can accurately detect and determine short circuit fault and ground fault; it is equipped with conventional fault processing function, which can realize centralized/local feeder automation (FA);
  • it is equipped with standard LCD display screen, which can provide user-friendly human-machine interaction interface.
  • Support real-time data communication, embedded with security chip of state secret algorithm to ensure the integrity, confidentiality and availability of data interaction;
  • Support BeiDou/GPS positioning function; support Bluetooth communication for local operation and maintenance.
  • Adopting "domestic core" as the core hardware architecture, modularized design concept, any module can be upgraded and replaced individually;
  • Adopting embedded real-time multi-tasking operating system, with dual-area redundant backup and self-recovery technology for operating system, important programs and parameters.
  • The standardized pole mounted circuit breaker of primary and secondary integration has the features of wide measuring range, high precision, high reliability, high degree of standardization, and interchangeability of equipment from different manufacturers.
