The characteristics of DTS mfumo wa kipimo cha joto cha fiber optic iliyosambazwa

Gridi mahiri ya mfumo wa nguvu ni pamoja na mitambo ya nguvu, gridi za juu-voltage, vituo vidogo, vituo vya usambazaji, nk., hasa ikiwa ni pamoja na jenereta, transfoma, nyaya za nguvu, swichi na vifaa vingine vya nguvu. Vifaa vya nguvu kawaida hufanya kazi katika mazingira kama vile voltage ya juu, mashamba yenye nguvu ya umeme, na mizigo ya joto, na mazingira ya kazi hayana mtu na hayafuatiliwi. Kama miundombinu ya uhandisi, gridi mahiri inahusisha mahitaji ya umeme ya maelfu ya kaya, na joto la uendeshaji wa vifaa vya nguvu ni jambo muhimu katika kuhakikisha uendeshaji salama wa gridi ya taifa ya smart. Ikiwa ni transfoma, nyaya za nguvu, au vifaa vingine vya nguvu, kama sehemu muhimu za mfumo wa nguvu, zinaweza kusababisha joto la ndani au cheche za arc kutokana na matatizo fulani ya mzunguko au mambo ya nje, kusababisha moto na kusababisha hasara kwa uzalishaji na maisha ya watu. Kwa hiyo, ili kuepusha tukio baya kama hilo, ni haraka kufanya ufuatiliaji wa joto wa kina wa vifaa vya nguvu. 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, zaidi kukabiliwa na overheating na kuungua ajali, ambayo inaweza kusababisha hasara kubwa kiuchumi.

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. Sensor moja ya hatua ya joto hupima hatua fulani katika uwanja wa joto na usahihi wa juu wa kipimo na kuegemea, lakini ni vigumu kupima usambazaji wa pointi nyingi katika uwanja wa joto. To solve the measurement problem of temperature field multi-point distribution, a quasi distributed sensor ya joto ya fiber optic 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, temperature sensing fiber optic, 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.

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, with advantages such as long measurement distance, no measurement blind spots, ufuatiliaji wa wakati halisi, na nafasi sahihi. It is widely used in fields such as transportation tunnels, njia za chini ya ardhi, nguvu, kemikali za petroli, na uhifadhi wa maji.
