Digital deeply integrated pole-mounted circuit breaker
Model：
HZW32-12
Overview：
Based on the electronic sensor and on-site digitization, the digitally deeply integrated pole-mounted circuit breaker further integrates ceramic capacitor power taking, finally eliminating the risk of ferromagnetic resonance of electromagnetic transformer. It has a higher degree of integration, and installation with electricity is faster, helping users improve the power supply reliability.
  1. Safety: Deep integration of primary and secondary equipment, reducing primary auxiliary equipment, without increasing the risk of failure; the interlocking device is adopted to eliminate the potential safety risk of mis-remote control caused by automation from the equipment.
  2. Effectiveness: Realize the selective tripping of short-circuit faults (multi-level precise differential coordination); realize the selective automatic isolation of single-phase ground faults (transient method fault location).
  3. Advancement: Adopting built-in ECT and EVT; solving the problem of terminal power supply by adopting capacitance pickup technology; the protection level can reach IP67; the local discharge of the whole machine is no more than 20pC.
  4. Intelligent: The terminal relies on machine learning and original algorithms to research and automate judge short-circuit or single-phase ground faults by itself and issue action commands.
  5. Usability: Easy to use, no change in operating habits, no need to increase the operating tools and operating steps, no need for professional training; factory commissioning, maintenance using modular replacement, support for hot-swapping, greatly reducing the dependence on professional and technical personnel.
  6. Miniaturization: With the in-depth integration of primary and secondary (built-in ECT, EVT), the weight is reduced by more than 20kG, reducing the difficulty of on-site construction and improving the installation efficiency.
