Measurement and control device (Integrated fault isolation device)
Model：
HZW32-12
Overview：
The 10KV measurement and control device (integrated fault isolation device) is an intelligent monitoring device that puts the vacuum interrupter chamber, operating mechanism, 10kV line high-voltage energy-taking power supply, intelligent measurement and control terminal, current and voltage sensors, and other components in an integrated design. It integrates the functions of the circuit breaker, 10kV line high-voltage energy-taking power supply, current and voltage sensors, and intelligent measurement and control terminal. It can monitor the operation status of the power distribution line online. By using the mobile GPRS/APN or 4G/APN communication private network, the detection data is uploaded to the management system. It should have the functions of monitoring, metering, protection, fault location, and isolation of the power distribution operation line.

  1. Integrated design, no additional wiring work for on-site installation. The overall weight does not exceed 130kg, and the power consumption of the device operation is less than 3W.
  2. The working scheme of the 10kV line high-voltage energy acquisition power supply adopts a miniaturized and lightweight high-voltage capacitor for power taking. Weight less than 2kg, output power not less than 3W.
  3. The intelligent measurement and control terminal has good electromagnetic compatibility to ensure the data collection, processing, and sending work without interference.
  4. The device comes with a backup working power supply. In the case of a line blackout, the backup power supply normal operation of not less than 120 hours, or meets the circuit breaker for more than 30 consecutive opening and closing operations.
  5. The device has an anti-open-circuit design and also has the function of replacing the secondary terminals directly with electricity after being put into operation on the line.
  6. The normal working start voltage of the device is 4.5 kV (phase voltage). When the device works at the rated voltage of the line, the capacitance current passing through the primary side needs to be less than 10 mA.
