Розумна мережа енергосистеми включає електростанції, високовольтні мережі, підстанції, розподільні станції, Тощо., зокрема генератори, трансформатори, силові кабелі, вимикачі та інше силове обладнання. Енергетичне обладнання зазвичай працює в таких середовищах, як висока напруга, сильні електричні поля, і теплові навантаження, а робоче середовище не обслуговується та не контролюється. Як інженерна інфраструктура, розумна мережа забезпечує потреби в електроенергії тисяч домогосподарств, і робоча температура енергетичного обладнання є важливим фактором у забезпеченні безпечної роботи інтелектуальної мережі. Будь то трансформери, силові кабелі, або інше силове обладнання, як важливі компоненти енергосистеми, вони можуть спричинити локальний перегрів або іскроутворення через деякі проблеми з ланцюгом або зовнішні фактори, призводять до пожеж і завдають збитків виробництву та життю людей. Тому, in order to avoid such a malignant event, необхідно терміново провести комплексний температурний моніторинг енергетичного обладнання. For cable tunnels used to accommodate a large number of cables laid on cable supports in corridors or tunnel structures, the environmental temperature and cable operating conditions can only
When a malfunction occurs, it is found that the longer the operating time, the more prone it is to overheating and burning accidents, which may cause huge economic losses.
Application of distributed fiber optic temperature measurement system in fiber optic temperature sensors
The existing electronic temperature sensors use point type temperature measurement, which is prone to electromagnetic interference and is not suitable for strong electromagnetic scenarios, while fiber optic temperature sensors are not affected by electromagnetic interference and are very suitable for temperature monitoring in power systems. Fiber optic temperature sensors include single point temperature sensors and quasi distributed fiber optic temperature sensors. Одноточковий датчик температури вимірює певну точку в температурному полі з високою точністю та надійністю, але важко виміряти розподіл кількох точок у температурному полі. To solve the measurement problem of temperature field multi-point distribution, a quasi distributed волоконно-оптичний датчик температури composed of a multiplexed fiber optic temperature sensor and an array of fiber optic temperature sensors has emerged. The quasi distributed fiber optic temperature sensor uses a single point fiber optic sensor array to form a spatial network distribution, achieving distributed fiber optic temperature measurement.
Distributed fiber optic thermometer is an optical time-domain temperature monitoring system, which is a widely used distributed fiber optic temperature measurement system both domestically and internationally. The system consists of a temperature measurement host, волоконно-оптичний датчик температури, and DTS backend analysis software.
The distributed temperature measurement fiber optic system is based on the principle of Raman scattering in light, integrating optical time-domain reflection (ОТДР) technology and the temperature sensitive characteristics of scattered light. It detects temperature changes at different positions along the fiber optic and achieves truly distributed measurement through intelligent analysis of DTS backend software data. It can continuously measure the temperature at any point along the fiber optic.
