The main function

  • Protective function: Automatic identification of fault current, realizing instantaneous current speed, time-limited current speed, timing overcurrent, directional overhang, single-phase grounding protection, cold load start suppression, etc.

  • Measurement function: Measure the three-phase current, three-phase voltage, active power, no workability, power supply, reactive power, power factor, and frequency.

  • control function: The local operation and distant control can be realized, and the fault location of the line can be automatically implemented according to the requirements of the line, the fault isolation and quickly restore non-fault line power supply, realize the low frequency automatic load, the capacitor automatic investigation, the automatic output of the alternate power supply is automatically related.\"

  • Data recording function: Automatically record and store information such as operation, operation, and failure.

  • Intelligent function: Online monitoring device performance parameters, online programming, can cooperate with the main station of the distribution network, implement remote control management of the device, realize the local, distant or hierarchical control network automation system function.


main feature

  • Three hero-magnet operating mechanisms, less components, low consumption, stable and reliable. No need to regular maintenance, the agency life is 100,000;

  • The outdoor hydrophobic epoxy resin is used as an insulating material, light weight, and has more than 40 years, no SF6, no environmental pollution, no gas leaks, meet environmental requirements;

  • The rapid algorithm with national patent technology (patent number: ZL200720037710.7) is used to make the override of the fault line. Effectively avoid the problem of cross-level trip;

  • Using a single-phase grounding protection system having a national patent technology (patent number: ZL201020178325.6) without increasing the configuration, an online judgment of single-phase failure of the small current grounding system can be achieved, and the alarm or trip operation is given according to the set value;

  • Built-in voltage, current sensor, no need to extract measurements with high precision, protect the desired various electrical feature amounts required for external PT and CT;

  • With automatic reclosing function, effectively avoid power-on accidents caused by instantaneous failures, so that the distribution network can automatically complete the fault isolation and recovery power supply in the case of no main station.

  • The temperature measurement and temperature correction technique is used, so that the switching equipment can be reliable and stable under different environmental conditions;

  • All stainless steel cabinets, no corrosion, maintenance;

  • Control system operation interface is friendly, full English system, parameter settings are convenient and fast. Have a human interface, which can be convenient to implement parameter settings, action record queries;

  • With data recording function, you can keep recent 256 data records, operations, failures, etc.

  • The professional power management module provides automatic switching function of the second power supply (AC / DC100, 220V) while having a professional battery management.
