1. Gambaran Keseluruhan Sensor Pemantauan Suhu Transformer
Sebagai peralatan teras sistem kuasa, transformer’ operasi yang selamat dan stabil secara langsung berkaitan dengan kebolehpercayaan keseluruhan grid kuasa. Transformer menghasilkan haba yang ketara semasa operasi, dan terlalu panas adalah salah satu punca utama kegagalan transformer. Data statistik menunjukkan bahawa lebih kurang 40% kegagalan transformer adalah berkaitan dengan keabnormalan suhu, menjadikannya penting untuk mewujudkan sistem pemantauan suhu yang komprehensif untuk memastikan operasi transformer yang selamat.
Penderia pemantauan suhu pengubah ialah peranti pengukuran ketepatan yang direka khusus untuk pemantauan masa nyata suhu komponen pengubah kritikal. Dengan memasang penderia suhu di lokasi utama seperti belitan pengubah, suhu minyak, teras besi, dan sesendal, keabnormalan suhu dapat dikesan dengan segera, langkah perlindungan yang sewajarnya boleh diambil, dan kerosakan peralatan dan kemalangan dapat dielakkan. Modern transformer temperature monitoring systems not only provide real-time temperature data but also feature intelligent functions such as trend analysis, fault warning, dan pemantauan jarak jauh, 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. Penderia suhu gentian pendarfluor are the ideal choice for winding temperature monitoring, featuring outstanding advantages such as complete immunity to electromagnetic interference, prestasi penebat yang sangat baik, dan ketepatan pengukuran suhu tinggi. 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 persekitaran medan magnet yang kuat, 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. Untuk transformer kritikal, 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, pemerolehan data, penghantaran komunikasi, protection logic and other aspects. Susun atur titik pemantauan harus mengikut prinsip perlindungan utama dan rasional ekonomi, memasang penderia suhu di lokasi kritikal dan titik lemah transformer. Transformer kritikal yang besar harus menggunakan rangkaian pemantauan berbilang peringkat, termasuk pemantauan menyeluruh suhu penggulungan, suhu minyak, suhu teras besi, suhu sesendal, dll.
Reka bentuk logik perlindungan suhu harus ditetapkan ambang perlindungan pelbagai peringkat, termasuk suhu amaran, suhu penggera, suhu perjalanan dan tahap lain yang berbeza. Apabila suhu melebihi nilai amaran, isyarat amaran dikeluarkan untuk mengingatkan kakitangan penyelenggaraan supaya memberi perhatian; apabila melebihi nilai penggera, penggera audio-visual diaktifkan dan peristiwa dirakam; apabila mencapai nilai perjalanan, beban pengubah diputuskan secara automatik untuk memastikan keselamatan peralatan. Protection logic should also consider load regulation control, secara automatik mengurangkan operasi beban apabila suhu menghampiri had.
Pemprosesan Data dan Diagnosis Kerosakan
Sistem pemantauan suhu pengubah moden mempunyai keupayaan pemprosesan dan analisis data yang berkuasa. Sistem boleh mengumpul data suhu daripada titik pemantauan dalam masa nyata, menghantar ke pusat pemantauan melalui pelbagai kaedah komunikasi termasuk Ethernet, gentian optik, dan tanpa wayar. Algoritma diagnostik pintar boleh mengenal pasti corak suhu yang tidak normal, melakukan analisis trend dan ramalan kesalahan, menyediakan asas saintifik untuk keputusan operasi dan penyelenggaraan.
Fungsi diagnosis kerosakan termasuk pengesanan mutasi suhu, analisis kadar kenaikan suhu, dan pengecaman anomali taburan suhu. Dengan menubuhkan model garis dasar suhu dan perpustakaan ciri kerosakan, sistem secara automatik boleh mengenal pasti potensi risiko kerosakan, achieving transformation from passive maintenance to active prevention. Application of data mining and machine learning technologies further enhances diagnostic accuracy and prediction capabilities.
