Modern transformer temperature monitoring systems not only provide real-time temperature data but also feature intelligent functions such as trend analysis, fault warning, and remote monitoring, providing strong support for safe transformer operation and predictive maintenance.

2. Transformer Temperature Monitoring Sensor Technology Types

Winding Temperature Sensors

Winding temperature monitoring is the core element of transformer thermal protection. Fluorescent fiber temperature sensors are the ideal choice for winding temperature monitoring, featuring outstanding advantages such as complete immunity to electromagnetic interference, उत्कृष्ट इन्सुलेशन प्रदर्शन, and high temperature measurement accuracy. Sensors can be directly embedded inside windings to achieve precise monitoring of winding hot spot temperatures. While PT100 RTD sensors have lower costs, they are susceptible to interference in strong electromagnetic field environments and are mainly used for economical monitoring solutions in small and medium transformers.

Oil Temperature Monitoring Sensors

Transformer oil temperature monitoring includes top oil temperature and average oil temperature measurement. Top oil temperature sensors are typically installed at the top of transformer oil tanks to monitor temperature changes at the highest oil temperature points. Multi-point oil temperature monitoring systems can provide oil temperature distribution information, helping analyze heat transfer patterns inside transformers. Fluorescent fiber sensors perform excellently in oil temperature monitoring, being unaffected by oil media with good long-term stability.

Iron Core Temperature Sensors

Iron core temperature monitoring is important for discovering faults such as local overheating and multiple grounding points. Since iron cores operate in strong magnetic field environments, traditional metal sensors are susceptible to magnetic field interference and induction heating effects. Fluorescent fiber sensors are completely unaffected by magnetic fields, making them the best choice for iron core temperature monitoring. Installation must consider insulation requirements and mechanical fixing reliability.

Bushing Temperature Sensors

Bushings are one of the weak links in transformers, and abnormal bushing temperatures often indicate poor contact or insulation deterioration. Infrared temperature measurement technology can achieve non-contact monitoring of bushing surface temperatures, suitable for live detection. महत्वपूर्ण ट्रांसफार्मर के लिए, fluorescent fiber sensors for contact temperature measurement are recommended to provide higher measurement accuracy and reliability.

Cooling System Temperature Sensors

Cooling system temperature monitoring includes cooler inlet/outlet temperatures, fan temperatures, and oil pump temperatures. Temperature monitoring of these points helps evaluate cooling system efficiency and promptly detect cooling equipment failures. Common RTD or thermocouple sensors can meet requirements with economical costs and simple maintenance.

3. Transformer Temperature Monitoring System Design and Applications

Monitoring System Design Essentials

Transformer temperature monitoring system design must comprehensively consider monitoring point layout, आंकड़ा अधिग्रहण, communication transmission, protection logic and other aspects. Monitoring point layout should follow principles of key protection and economic rationality, installing temperature sensors at critical locations and weak points of transformers. Large critical transformers should adopt multi-level monitoring networks, including comprehensive monitoring of winding temperature, तेल का तापमान, लौह कोर तापमान, bushing temperature, वगैरह.

Temperature protection logic design should set multi-level protection thresholds, including warning temperature, अलार्म तापमान, trip temperature and other different levels. When temperature exceeds warning values, warning signals are issued to remind maintenance personnel to pay attention; when exceeding alarm values, audio-visual alarms are activated and events are recorded; when reaching trip values, transformer load is automatically disconnected to ensure equipment safety. Protection logic should also consider load regulation control, automatically reducing load operation when temperature approaches limits.

Data Processing and Fault Diagnosis

Modern transformer temperature monitoring systems possess powerful data processing and analysis capabilities. Systems can collect temperature data from monitoring points in real-time, transmitting to monitoring centers through various communication methods including Ethernet, फाइबर ऑप्टिक, and wireless. Intelligent diagnostic algorithms can identify abnormal temperature patterns, perform trend analysis and fault prediction, providing scientific basis for operation and maintenance decisions.

Fault diagnosis functions include temperature mutation detection, temperature rise rate analysis, and temperature distribution anomaly identification. By establishing temperature baseline models and fault feature libraries, systems can automatically identify potential fault risks, achieving transformation from passive maintenance to active prevention. Application of data mining and machine learning technologies further enhances diagnostic accuracy and prediction capabilities.
