The modern urban construction has put forward higher requirements for our power transmission. With the continuous development of the power industry, urban overhead transmission lines are being replaced by underground high-voltage cables. Hala ere, due to the complex environment in which underground cables are located, the insulation performance of underground cables becomes a key issue in determining the reliability of power transmission. The aging and damage of cable insulation are closely related to the long-term operating core temperature. When cable lines are buried underground, it is particularly important to monitor the operating temperature of the cable lines, 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 zuntz optikoko tenperatura neurtzeko sistema banatua 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. Meanwhile, 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, distributed fiber optic temperature measurement systems have many natural advantages, mainly including:

1) Continuous distributed measurement
Distributed fiber optic 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) Anti electromagnetic interference, achieving on-site no electricity detection.
The optical fiber itself is composed of quartz material, which is completely electrically insulating; Aldi berean, 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. Fiber optic sensors, due to their complete electrical insulation, can withstand the impact of high voltage and high current.

4) Long measurement distance, suitable for remote monitoring.
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.
In theory, 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) Long lifespan, kostu baxua, and simple system.
The material of optical fibers is generally quartz glass, which has the characteristics of non corrosion, fire resistance, water resistance, and long service life, and can usually serve for 30 years.

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,
