kichunguzi cha kebo ya nyuzi macho ya kuhisi halijoto

Ujenzi wa kisasa wa mijini umeweka mahitaji ya juu zaidi kwa usambazaji wetu wa nguvu. Pamoja na maendeleo endelevu ya tasnia ya nguvu, Njia za upitishaji barabara za mijini zinabadilishwa na nyaya za chini ya ardhi zenye voltage ya juu. Hata hivyo, kutokana na mazingira magumu ambayo nyaya za chini ya ardhi ziko, utendaji wa insulation ya nyaya za chini ya ardhi inakuwa suala muhimu katika kuamua kuaminika kwa maambukizi ya nguvu. Kuzeeka na uharibifu wa insulation ya cable ni karibu kuhusiana na joto la msingi la uendeshaji wa muda mrefu. Wakati mistari ya cable imezikwa chini ya ardhi, ni muhimu hasa kufuatilia joto la uendeshaji wa mistari ya cable, grasp their operating conditions, and provide a basis for future cable line selection and design current carrying capacity calculation. As an emerging phenomenon in transmission lines, power cable tunnels play an important role in the operation of the power grid. Ensuring the safe operation of power cable tunnels is of great significance.
To measure and analyze the temperature of the two cable lines in operation, in order to determine the impact of different laying environments on the cable current carrying capacity under a certain current carrying capacity, in order to fully utilize the cable conveying capacity and ensure cable safety. The temperature measurement fiber is laid on the surface of the above-mentioned cable.

The mfumo wa kipimo cha joto cha fiber optic iliyosambazwa monitors the surface temperature of the cable and determines its operation by converting the core temperature of the cable. It evaluates the system and calculates the current carrying capacity of the system at any time, ensuring the safe and economical operation of the cable system. By monitoring the temperature of the cable, the operating temperature of the cable can be controlled at any time, which can not only avoid long-term operation of the cable under overload, but also adjust the load of the cable in a timely manner according to the operating temperature, which is greatly beneficial for the safe and economical operation of the power system. Wakati huo huo, by comparing the impact of different cable laying methods on current carrying capacity, a basis is provided for the selection of cable laying methods in the future.

Compared with traditional sensors, mifumo ya kipimo cha joto cha optic iliyosambazwa have many natural advantages, mainly including:

1) Continuous distributed measurement
Fiber optic iliyosambazwa sensors are truly distributed measurements that can continuously obtain measurement information along the detection fiber optic for tens of kilometers, greatly reducing false alarm and false alarm rates, and achieving real-time monitoring.

2) Kuingilia kati kwa sumakuumeme, achieving on-site no electricity detection.
The optical fiber itself is composed of quartz material, which is completely electrically insulating; Wakati huo huo, the signal of fiber optic sensors is carried by optical signals, which are inherently safe and not affected by any external electromagnetic environment interference. The tank area can enter without electrification, thus eliminating the potential danger of electric sparks in areas containing combustible mixed gases, and achieving on-site zero electricity detection, which is inherently safe.

3) Intrinsic lightning protection.
Thunder often damages a large number of electrical sensors. Sensorer za optic za nyuzi, due to their complete electrical insulation, can withstand the impact of high voltage and high current.

4) Umbali mrefu wa kipimo, yanafaa kwa ufuatiliaji wa mbali.
The two outstanding advantages of optical fiber are large data transmission volume and low loss. It can achieve remote monitoring for tens of kilometers without the need for relays.

5) High sensitivity and measurement accuracy.
Kwa nadharia, the sensitivity and measurement accuracy of most fiber optic sensors are superior to general sensors, and this has been proven by mature products in practice.

6) Muda mrefu wa maisha, gharama ya chini, na mfumo rahisi.
The material of optical fibers is generally quartz glass, ambayo ina sifa za kutokuwa na kutu, upinzani wa moto, upinzani wa maji, na maisha marefu ya huduma, and can usually serve for 30 miaka.

Taking into account the cost of the sensor itself and future maintenance costs, the use of fiber optic sensors can greatly reduce the operating costs of the entire project,
