Date: November 10, 2025 09:23:23

Dry-type transformer intelligent management terminal system is a set of integrated multi-dimensional condition monitoring, data acquisition, analysis and early warning and remote control of intelligent systems, the core role is to realize the whole life cycle of dry-type transformer efficient operation and maintenance and risk management and control, through accurate monitoring and standardized communication to ensure the safe and stable operation of equipment.

core functionality

  • Full-dimensional real-time monitoring: covering the transformer body winding and core temperature, local discharge status, vibration, operating environment temperature and humidity, operating noise, as well as transformer cable joints instantaneous discharge arc light, smoke and other key parameters.
  • Data Processing and Early Warning: Analyze multi-dimensional data through edge computing, trigger multi-level alarms such as sound and light, SMS, platform push when abnormal, and support fault traceability and trend prediction.
  • Remote operation and maintenance and control: you can remotely check the operation status, adjust parameters, and support automatic start/stop, load adjustment and other control functions in some scenarios to enhance the convenience of operation and maintenance.
  • Standardized communication interconnection: Data uploading and commanding through network fiber optic communication, IEC61850 protocol and station level communication tablets to ensure communication stability and compatibility.

core component

  • Sensor modules: temperature sensors (fiber optic / PT100), local discharge sensors, vibration sensors, temperature and humidity sensors, noise sensors, arc light sensors, smoke sensors, comprehensive coverage of data acquisition needs.
  • Data acquisition unit (DTU): summarize the data of each sensor, complete analog-to-digital conversion and preliminary pre-processing to ensure data accuracy.
  • Communication module: support network fiber, 4G/5G, LoRa, Ethernet, etc., compatible with the IEC61850 protocol and station-level communication tablets to achieve two-way communication.
  • Cloud platform / local server: storage of multi-dimensional data, visualization of operational status, data analysis and alarm management.
  • Terminal control unit: receives platform commands, performs control operations, and responds quickly to abnormalities by linkage alarm mechanism.

Application Advantages

  • Reduce the risk of failure: Multi-dimensional monitoring covers thermal, electrical, acoustic, vibration and other failure triggers to avoid equipment damage caused by overloading, overheating, insulation aging, and discharge.
  • Enhance the efficiency of operation and maintenance: Reduce the frequency of manual inspection, remotely grasp the full state of the equipment, shorten the fault location and processing time.
  • Optimize resource allocation: Through data trend analysis, it provides accurate data support for load adjustment and maintenance plan formulation, and extends the service life of equipment.
