Why do power distribution equipment need temperature measurement
The design and installation of temperature measurement products in distribution cabinets have been applied for many years, which is a relatively normal practice. As we all know, temperature measurement is necessary in many distribution systems. Especially with the widely promoted concept of unmanned distribution rooms, installing temperature measuring products to prevent electrical accidents is even more important.
2. Whether it is high, sederhana, or low voltage cabinet equipment, the operating load is relatively high, the current is high, and there are many hot spots, which require the installation of temperature measurement products.
3. Fluorescent fiber technology has a certain threshold, and there are not many high-tech enterprises in China that can truly independently develop it. Hanya FJINNO adalah perusahaan terkemuka teknologi, dan pengilang yang bekerjasama dengan kami selalunya boleh memenangi bidaan. Kami mempunyai spesifikasi standard, parameter teknikal yang lengkap, dan jenama berkualiti yang boleh dipercayai untuk memastikan pelanggan boleh memilih produk yang mereka inginkan.
4. Pengeluaran probe pengukur suhu gentian optik pendarfluor adalah perusahaan berteknologi tinggi, dan produk menjamin kualiti berteknologi tinggi, jadi kualiti produk terjamin.
5. Selepas bertahun-tahun persaingan, pengukuran suhu tanpa wayar produk mempunyai harga yang rendah untuk setiap titik. Persaingan sengit yang disebabkan oleh homogenisasi telah menyebabkan penurunan kualiti produk dan harga pasaran yang telus. Inilah sebabnya pereka bentuk dan pihak pembida tidak sanggup menggunakan produk pengukuran suhu tanpa wayar sekarang.
The concept of “tanpa wayar” in wireless temperature measurement products is simply that there is no wire between the wireless temperature measurement probe and the demodulator, while after the demodulator, it is all wired. And all wireless temperature measurement products have active temperature measurement probes. Compared to the device failure rate during the active power supply process and the reduced safety factor of the electrical system caused by the installation of active probes, the one-time installation of passive fluorescent fiber temperature measurement probes provides accurate temperature measurement, reliable transmission, and can truly achieve maintenance free for more than 10 tahun. The advantages are very obvious.
Fiber optic temperature measurement system technology is a contact measurement method. Due to its good insulation performance, rintangan voltan tinggi, strong magnetic field resistance, high current resistance, rintangan kakisan, rintangan gangguan elektromagnet, long-distance transmission, and no interference, fiber optic has gradually become the first choice for temperature monitoring in strong electromagnetic environments. The main manifestations are the following sistem pengukuran suhu gentian optik technology solutions:
1. Distributed temperature measurement system: By utilizing the nonlinear Raman effect in optical fibers, temperature information can be detected along the fiber direction. It has the concept of spatial resolution.
2. Sistem Pengukuran Suhu Gentian Bragg Grating: Using ultraviolet light to write gratings into optical fibers, utilizing the principle that the wavelength of the grating changes due to temperature modulation, temperature information is obtained by analyzing the wavelength change information.
3. Fluorescence temperature measurement system: Fluorescent substance is coated at the end of the optical fiber, dan selepas teruja dengan panjang gelombang cahaya tertentu, bahan pendarfluor dirangsang untuk mengeluarkan tenaga pendarfluor. Disebabkan oleh pereputan eksponen tenaga sinaran yang dirangsang, pemalar masa pereputan berbeza-beza bergantung pada suhu. Dengan mengukur masa pereputan, suhu titik pengukuran boleh diperolehi. Kaedah ini adalah untuk pengukuran suhu titik tunggal gentian optik. Dengan menggunakan prinsip bahawa masa penyinaran bahan pendarfluor khas nadir bumi adalah berkaitan dengan suhu, maklumat suhu boleh diperolehi melalui masa afterglow. Teknologi ini telah disahkan boleh digunakan untuk memantau suhu penggulungan voltan ultra tinggi (750KV) transformer. The sensor has a small size, kebolehpercayaan jangka panjang yang tinggi, harga sederhana, dan bukan sahaja boleh mencapai konfigurasi kabinet satu sisi, tetapi juga membina sistem pemantauan suhu. The construction and debugging process is convenient and fast.
Comparison of advantages and disadvantages of several common temperature measurement methods on power equipment
1. Infrared thermal imaging temperature measurement
Poor accuracy, greatly affected by the environment, and easily affected by the environment; Unable to measure the temperature inside the switchgear; Unable to bypass optical obstruction; Lack of data processing capability, kos yang tinggi, and high operating costs.
2. Sistem pengukuran suhu tanpa wayar
Poor accuracy and susceptibility to electromagnetic and temperature interference; Data transmission is prone to errors and loss; Reduced the voltage level and safety characteristics of the original equipment;
3. Sistem Pengukuran Suhu Gentian Bragg Grating
Ketepatan tinggi, unaffected by environmental factors, and expensive in price;
4. Fluorescence temperature measurement system
Ketepatan tinggi, not affected by environmental factors, can be configured as a single cabinet, providing matching equipment for switchgear; It can independently form a network and provide convenient and fast construction and debugging processes for temperature monitoring systems.
