1.1 Antecedentes de la aplicación
The intelligence and standardization of temperature monitoring in busbar power supply systems are the basis for real-time power transmission status, condiciones de temperatura, and even patrol detection.
In the practical application of busbars, due to long-term operation in the air and the influence of surrounding temperature and humidity, expansión y contracción térmica, escalado de superficie, Puede producirse oxidación o corrosión., resulting in loose contacts and poor contact, especially in some large buildings (como las grandes fábricas, edificios de gran altura, etc.) where the installation position of busbars cannot be monitored manually. Users often neglect the safety management of busbars. Once the temperature of the busbar joints during operation is abnormally high, it may lead to fires or major safety and quality accidents, causing huge and irreparable personal injury and economic property losses to enterprises.
El conducto de autobús está en un estado completamente cerrado durante la operación y generalmente está en un estado activo a largo plazo., making daily maintenance and inspection very inconvenient. Por lo tanto, it is necessary to monitor the temperature of the bus duct to improve its reliability.
Detección de temperatura distribuida (EDE) is currently the most advanced temperature measurement technology internationally. DTS distributed fiber optic temperature sensing is completely different from traditional temperature sensing systems based on electrical signals. Whether it is the difficulty of measurement technology, the content and indicators of temperature measurement, or the occasions and scope of measurement, it has been raised to a new stage. el distribuido sensor de temperatura de fibra óptica system can measure and display the temperature values of various points on the entire continuous fiber optic cable in the form of a continuous function of distance. This technology only requires one optical fiber to measure temperature at a distance of ten kilometers. Domestic and international engineering application experience has shown that distributed fiber optic temperature sensing systems are highly effective monitoring devices for temperature monitoring in power systems.

A large number of practical applications and tests have proven that distributed fiber optic temperature sensing technology has excellent stability and reliability. Además, optical fibers have the characteristics of corrosion resistance, resistencia a altas temperaturas, no static electricity, and no radiation. This enables the system to provide stable, confiable, and economical solutions for various industrial needs based on temperature detection.
En resumen, fiber optic temperature sensing technology is currently the most advanced temperature sensing technology internationally, with inherent explosion-proof, fuerte resistencia a la interferencia electromagnética, buen aislamiento electrico, protección contra rayos, alta precisión, peso ligero, y tamaño pequeño. It can simultaneously measure the temperature distribution on the entire fiber optic cable, surpassing all traditional quasi distributed temperature measurement or alarm systems. It is also a highly intelligent and automated monitoring technology, which does not require manual inspection of the monitored area. The monitoring room screen can display temperature information of each point in the entire monitoring area; Cuando hay un punto de sobrecalentamiento, puede sonar o encender una alarma, or send it to relevant personnel via SMS. It can effectively solve the problem of temperature monitoring in complex environments that traditional temperature measurement techniques could not solve before. It can accurately predict hot spots before accidents occur, with a positioning accuracy of 1 metro, y mostrar la evolución de la temperatura del punto caliente, truly achieving preventive measures. Por lo tanto, distributed fiber optic temperature sensors have received widespread attention worldwide and have begun to be widely applied.
