ZY-DGA500 oil chromatography, ZY-TX iron core ground current online monitoring system

ZY-DGA500 oil chromatography on-line monitoring device is our company's latest on-line monitoring system for gas and micro-water content in oil, and can integrate on-line monitoring system of iron core ground current according to customer requirements, and intelligent components that meet the national IEC61850 communication protocol. The monitoring device is connected to the transformer body only through the oil inlet and outlet ports, and is easy to install. It adopts the oil circulation working method, no pollution, no fuel consumption, and accurate sampling. The shortest monitoring period can be set to 1 hour, and the maximum detection period can be set arbitrarily. The software system is powerful and easy to operate. It can query real-time data, real-time maps, historical data, trend charts, etc.

  The "DL / T 572 Power Transformer Operating Regulations" requires that the current in the transformer core grounding wire cannot exceed 100MA. The ZY-TX core grounding online monitoring system can monitor the transformer core grounding current value 24/7, and can also When the current in the ground line is found to be greater than 100mA, a current limiting resistor is required to limit the current in the ground line to less than 100mA.
 
  System parameters:
  Working voltage: AC220V, -15% ~ + 15%; power frequency: 50Hz ± 0.5Hz.
  Ground current alarm value: 100mA, automatic alarm when the value is exceeded
