1. Project Overview
1.1 Application Background
The intelligence and standardization of temperature monitoring in busbar power supply systems are the basis for real-time power transmission status, temperature conditions, 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, thermal expansion and contraction, surface scaling, oxidation or corrosion may occur, resulting in loose contacts and poor contact, especially in some large buildings (such as large factories, super high-rise buildings, 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.
The bus duct is in a fully enclosed state during operation and is generally in a long-term live state, making daily maintenance and inspection very inconvenient. Per això, it is necessary to monitor the temperature of the bus duct to improve its reliability.
Sensor de temperatura distribuït (DTS) 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. The distributed fiber optic temperature sensor 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. A més, optical fibers have the characteristics of corrosion resistance, resistència a altes temperatures, no static electricity, and no radiation. This enables the system to provide stable, fiable, and economical solutions for various industrial needs based on temperature detection.
In summary, fiber optic temperature sensing technology is currently the most advanced temperature sensing technology internationally, with inherent explosion-proof, strong electromagnetic interference resistance, good electrical insulation, lightning protection, high precision, pes lleuger, and small size. 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; When there is an overheating point, it can sound or light an alarm, 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 metre, and display the evolution of hot spot temperature, truly achieving preventive measures. Per això, distributed fiber optic temperature sensors have received widespread attention worldwide and have begun to be widely applied.

1.2 Significance of Busbar Temperature Monitoring
Monitoring the temperature of the busbar has the following significance:
Safely increase the current carrying capacity of the circuit;
Can achieve periodic state monitoring;
Drive external alarm or other emergency systems;
Discovering hotspots (especially bus joints with potential accident hazards) and other environmental anomalies.

1.2.1 Provide technical support for the safety of busbar equipment
With the national standardization requirements for high-risk environments and the development of intrinsic safety optical communication technology, some technologies in optical communication have gradually provided a technical platform for the application of sensing fields, and distributed fiber optic sensors are one of them. It can scientifically and inherently safely complete the monitoring work of the busbar, and is the best choice for busbar temperature monitoring.
Real time online monitoring of bus temperature can be achieved. It can provide sound and light warnings, alarms, etc. for safety signals such as high and low temperatures and abnormal conditions.
1.2.2 Intrinsic safety of the equipment itself
This product adopts distributed fiber optic detection technology to achieve temperature measurement without electricity, which is truly inherently safe. Strong anti electromagnetic induction and anti-interference ability, very suitable for temperature monitoring applications in the coal mining industry, with great technical and safety advantages.
1.2.3 Application purpose
Distributed fiber optic temperature monitoring system is applied to various busbars and bus ducts, using distributed fiber optic measurement technology for real-time temperature monitoring, thereby achieving safe monitoring of the operation of busbar equipment.
