Fiber optic temperature sensor, Intelligent monitoring system, Distributed fiber optic manufacturer in China

In modern industry, the rise and fall of equipment operating temperature reflects the changes in equipment operating status and many physical characteristics. Abnormal or faulty operation of industrial equipment usually manifests as abnormal temperature changes. Therefore, temperature monitoring of industrial equipment operation is the most effective and economical means of equipment safety monitoring, which has significant significance for the safe operation of equipment.
With the development and application of fiber optic sensor technology, the fluorescence fiber optic temperature measurement system is currently the most advanced and effective temperature online monitoring system in the world, especially in fields such as high-voltage and strong magnetic field power systems. It can cover the monitoring blind spots that are difficult for traditional temperature sensors to reach, and has a broader application prospect.

Fiber optic temperature measurement is an important part of equipment status monitoring

In today’s smart grid era, the comprehensive monitoring system for power facilities is centered around intelligent control, and through the integrated application of IoT technology, it achieves all-weather status monitoring and intelligent control of the power grid environment. With network communication as the core, complete the collection and monitoring of station side video, environmental data, and security prevention data. Provide highly stable and reliable monitoring information resources. Save comprehensive monitoring operation and management costs, and achieve the goal of short-term investment and long-term benefits. Ensure improved efficiency in monitoring environmental management and provide a safe and comfortable working environment. The system software/hardware adopts a modular structure design to adapt to development needs, achieve scalability and variability, adapt to changes in the environment, and diversify the nature of work.
The necessity and significance of temperature measurement for power equipment

It is necessary to monitor the operation status of high-voltage transmission equipment by monitoring temperature changes in the power distribution system. The primary electrical equipment of the power system consists of circuit breakers, transformers, IGBTs, cables, busbars, switchgear, etc., which are connected by busbars, leads, and cables. The flow of current generates heat, so almost all electrical faults will cause temperature changes at the fault point. For example, cable joints, intermediate connections, partial discharge of high-voltage cables, overheating of dynamic and static contacts of high-voltage switchgear, and low-voltage electrical connections in power plants are signs of large-scale accidents and are also high-risk areas for power plant accidents.

The development of fiber optic temperature measurement technology has gradually led to the recognition of fiber optic temperature measurement systems in power systems, which have insulation and voltage resistance performance and stable working characteristics, and can achieve positioning temperature measurement and shorten the temperature measurement cycle. The fluorescent fiber optic temperature sensor adopts full fiber sensing and signal transmission, without electromagnetic interference and regular maintenance issues, and can operate reliably without maintenance for a long time, fully meeting the needs of unmanned power systems. The temperature monitoring system, through real-time online monitoring and data analysis, can grasp the operation status of equipment, timely detect hidden dangers and faults, prevent accidents, improve maintenance efficiency, and reduce maintenance and management costs.

By monitoring electrical equipment and their connecting parts such as circuit breakers, transformers, IGBTs, cables, busbars, and switchgear through online real-time temperature detection, pre disaster alarms can be achieved to ensure safe operation of the equipment. Especially for high-voltage switchgear, GIS, overheating caused by poor contact of internal contacts and eccentric insertion may lead to equipment damage. By continuously monitoring temperature, early warning can be achieved and detailed fault analysis data can be provided to ensure the safe operation of high-voltage switchgear.

At the same time, real-time temperature monitoring of power cables can issue fault warnings in advance to prevent fires from occurring; The monitoring of the heating status of busbars and cables under different loads and environmental temperatures can accumulate historical data, conduct current carrying limit analysis, and improve equipment utilization and economic benefits. Aging monitoring can timely detect local hotspots, slow down the aging rate through cooling measures, and prevent fires.

The fire prevention and fire monitoring of cable trenches in power plants and large metallurgical enterprises can provide early warning to prevent large-scale fire accidents caused by cable failures. In addition, temperature monitoring and alarm of distribution terminals are also crucial. Abnormal temperature rise that may occur during the operation of high-voltage circuit breakers, IGBTs, reactors, busbars and other equipment needs to be detected in a timely manner to prevent malignant power outages caused by poor contact, loose screws and other reasons.

Temperature monitoring of power equipment is crucial for ensuring the safe, stable, and efficient operation of the power system. The limitations of traditional temperature sensors in high voltage and electromagnetic interference environments limit their application in power equipment. The application of gallium arsenide fiber optic temperature measurement technology has effectively overcome these technical bottlenecks and brought significant significance and benefits. The introduction of fluorescent fiber optic temperature measurement technology provides a more reliable and efficient solution for temperature monitoring of power equipment, significantly improving the safety, stability, and economic benefits of the power system. Its widespread application in power equipment will undoubtedly bring significant technological progress and economic benefits.
