mifumo iliyosambazwa ya kutambua halijoto dts Inatumika kwa ufuatiliaji wa halijoto ya nyaya za handaki wakati wa kuvinjari

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, kufahamu kasi na hali ya uendeshaji wao, na kutoa msingi wa uteuzi wa mstari wa cable wa baadaye na hesabu ya uwezo wa kubeba cable. 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.

By monitoring the surface temperature of the cable and calculating the core temperature of the cable through conversion to determine its operating condition, a systematic evaluation is conducted, and the current carrying capacity of the system is calculated at any time to ensure 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.

The monitoring system monitors the surface temperature of the cable lines on site in real time, and displays the temperature values of the monitored cables throughout the entire process in the system through software, so that operators can keep track of the operation of the cables at any time. Comparing the impact of different cable laying methods on current carrying capacity provides a basis for the selection of cable laying methods in the future.

The power tunnel is an important component of the urban power system transmission and distribution mtandao, and is a key facility to ensure the safe, kuaminika, and economical operation of the power grid. By implementing ufuatiliaji wa joto la fiber optic and other measures on the cables inside the tunnel, the standardized management of power tunnels can be improved, providing a good environment for the safe operation of high-voltage power cables. Kwa sasa, our bureau has multiple power tunnels under design and construction demonstration, and construction will be carried out in the near future. This puts higher requirements on the operation and management of power tunnels. The operation work will rely on advanced technological means, refined management, and strive towards low-cost, ufanisi, fully monitored, and low defect direction.
