Como os sensores de temperatura de fibra óptica são aplicados em sistemas de potência-INNO

Na indústria moderna, o aumento e a queda da temperatura operacional do equipamento refletem as mudanças no status operacional do equipamento e muitas características físicas. A operação anormal ou defeituosa de equipamentos industriais geralmente se manifesta como mudanças anormais de temperatura. Portanto, O monitoramento da temperatura da operação de equipamentos industriais é o meio mais eficaz e econômico de monitoramento da segurança dos equipamentos, que tem um significado significativo para a operação segura do equipamento.
Com o desenvolvimento e aplicação da tecnologia de sensores de fibra óptica, o sistema de medição de temperatura de fibra óptica de fluorescência é atualmente o sistema de monitoramento on-line de temperatura mais avançado e eficaz do mundo, especialmente em campos como sistemas de energia de alta tensão e forte campo magnético. It can cover the monitoring blind spots that are difficult for traditional temperature sensors to reach, and has a broader application prospect.

Medição de temperatura de fibra óptica 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, transformadores, IGBTs, cabos, barramentos, comutador, etc., which are connected by busbars, pistas, e cabos. The flow of current generates heat, so almost all electrical faults will cause temperature changes at the fault point. Por exemplo, juntas de cabos, 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. O sensor de temperatura de fibra óptica fluorescente 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, transformadores, IGBTs, cabos, barramentos, 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, SIG, overheating caused by poor contact of internal contacts and eccentric insertion may lead to equipment damage. By continuously monitoring temperature, aviso antecipado pode ser alcançado e dados detalhados de análise de falhas podem ser fornecidos para garantir a operação segura de comutadores de alta tensão.

Ao mesmo tempo, o monitoramento da temperatura em tempo real dos cabos de energia pode emitir avisos de falha com antecedência para evitar a ocorrência de incêndios; O monitoramento do estado de aquecimento de barramentos e cabos sob diferentes cargas e temperaturas ambientais pode acumular dados históricos, conduzir análise de limite de transporte de corrente, e melhorar a utilização do equipamento e os benefícios econômicos. O monitoramento do envelhecimento pode detectar pontos de acesso locais em tempo hábil, retardar a taxa de envelhecimento através de medidas de resfriamento, e prevenir incêndios.

A prevenção e monitoramento de incêndios em valas de cabos em usinas de energia e grandes empresas metalúrgicas podem fornecer alerta precoce para evitar acidentes de incêndio em grande escala causados por falhas de cabos. Além disso, 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, reatores, 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, estável, 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, estabilidade, and economic benefits of the power system. Its widespread application in power equipment will undoubtedly bring significant technological progress and economic benefits.
