The characteristics of DTS rozproszony światłowodowy system pomiaru temperatury

W skład inteligentnej sieci systemu elektroenergetycznego wchodzą elektrownie, sieci wysokiego napięcia, Podstacje, stacje dystrybucyjne, itd., w szczególności generatory, Transformatory, kable zasilające, przełączniki i inny sprzęt zasilający. Sprzęt zasilający zwykle działa w środowiskach takich jak wysokie napięcie, silne pola elektryczne, i obciążenia cieplne, a środowisko pracy jest bezzałogowe i monitorowane. Jako infrastruktura inżynieryjna, inteligentna sieć zaspokaja zapotrzebowanie na energię elektryczną tysięcy gospodarstw domowych, a temperatura pracy urządzeń elektroenergetycznych jest ważnym czynnikiem zapewniającym bezpieczną pracę inteligentnej sieci. Czy to transformatory, kable zasilające, lub inny sprzęt zasilający, jako ważne elementy systemu elektroenergetycznego, mogą one powodować lokalne przegrzanie lub iskry łukowe z powodu problemów z obwodami lub czynników zewnętrznych, prowadząc do pożarów i powodując straty w produkcji i życiu ludzi. Więc, aby uniknąć tak złośliwego zdarzenia, pilnie należy przeprowadzić kompleksowy monitoring temperatury urządzeń elektroenergetycznych. 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, tym bardziej jest podatny na przegrzanie i poparzenia, co może spowodować ogromne straty gospodarcze.

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. Jednopunktowy czujnik temperatury mierzy określony punkt w polu temperatury z dużą dokładnością i niezawodnością pomiaru, ale trudno jest zmierzyć rozkład wielu punktów w polu temperatury. To solve the measurement problem of temperature field multi-point distribution, a quasi distributed światłowodowy czujnik temperatury 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, Światłowód wykrywający temperaturę, 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 (OTDR) 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.

Charakterystyka rozproszony światłowodowy system pomiaru temperatury

The measurement distance of the distributed fiber optic temperature measurement system ranges from a few kilometers to several tens of kilometers, and the spatial positioning accuracy can reach the level of 1m. It can conduct uninterrupted real-time online monitoring and transmit real-time data remotely, timely warning of fire hazards, and accurately locate the location of the fire. It can achieve distributed real-time measurement of temperature in a wide range of space, z zaletami takimi jak duża odległość pomiaru, brak pomiaru martwych punktów, monitorowanie w czasie rzeczywistym, and precise positioning. It is widely used in fields such as transportation tunnels, Metro, moc, Petrochemicznych, i oszczędzanie wody.
