Kaedah Pemantauan Suhu Transformer
beberapa kaedah digunakan untuk memantau suhu pengubah, masing-masing dengan kelebihan dan kekurangannya:
- Termokopel: Ini adalah tradisional penderia suhu that generate a voltage proportional to temperature. They are relatively inexpensive but susceptible to electromagnetic interference (EMI) in high-voltage environments.
- Pengesan Suhu Rintangan (RTD): RTD measure temperature based on the change in electrical resistance of a metal wire. They offer better accuracy than thermocouples but are also susceptible to EMI.
- Penderia Suhu Gentian Optik (KAKI): FOTS use light to measure temperature, making them immune to EMI. Different types of FOTS exist:
- Kisi Fiber Bragg (FBG): FBGs reflect a specific wavelength of light that shifts with temperature and strain.
- Taburan Raman: Uses the temperature-dependent intensity ratio of Raman-scattered light.
- Pereputan Pendarfluor: Langkah-langkah the temperature-dependent decay time of a fluorescent material.
- Inframerah (DAN) Termografi: IR cameras detect infrared radiation emitted by the transformer, allowing for non-contact pengukuran suhu. Namun begitu, IR thermography only measures surface temperature and may not accurately reflect internal winding suhu.
Pemasangan Sensor Gentian Optik dalam Transformer
Penderia gentian optik can be installed in both oil-immersed and dry-type transformers:
- Oil-Immersed Transformers: Sensors are typically installed within the oil, often attached to the windings or core. khusus kabel gentian optik and feedthroughs are used to ensure oil-tight sealing and prevent leaks. Sensors can be placed at strategic locations to monitor hot spots, such as the top oil temperature and winding hot-spot temperature.
- Transformer Jenis Kering: Penderia can be embedded within the windings during the manufacturing process or attached to the surface of the windings or core. Care must be taken to ensure proper thermal contact between the sensor and the component being monitored.
FJINNO, contohnya, offers pre-assembled sensor suhu gentian optik kits specifically designed for transformer installation, simplifying the process and ensuring reliable performance.
Kos dan Kelebihan Pemasangan Pemantauan Gentian Optik
Manakala kos permulaan bagi sistem pemantauan suhu gentian optik may be higher than traditional methods, they offer several long-term cost and installation advantages:
- Reduced Maintenance: Penderia gentian optik are passive devices with no moving parts, requiring minimal maintenance and calibration.
- Long Lifespan: Penderia gentian optik have a long lifespan, often exceeding the lifespan of the transformer itself.
- Kekebalan EMI: Immunity to electromagnetic interference eliminates the need for expensive shielding and grounding, which are often required for traditional sensors.
- Pengesanan Kerosakan Awal: Accurate and reliable pemantauan suhu allows for early detection of potential problems, preventing costly repairs and unplanned outages.
- Simplified Installation: Pre-assembled kits and specialized installation tools, like those offered by FJINNO, can simplify the installation process.
- Keselamatan: The non-conductive nature of optical fiber eliminates electrical bahaya keselamatan.
