As características do DTS sistema distribuído de medição de temperatura de fibra óptica
A rede inteligente do sistema de energia inclui usinas de energia, redes de alta tensão, subestações, estações de distribuição, etc., especificamente incluindo geradores, transformadores, cabos de alimentação, interruptores e outros equipamentos de energia. Equipamentos de energia geralmente operam em ambientes como alta tensão, campos elétricos fortes, e cargas térmicas, e o ambiente de trabalho não é tripulado e não monitorado. Como uma infraestrutura de engenharia, a rede inteligente envolve as necessidades de eletricidade de milhares de famílias, e a temperatura operacional do equipamento de energia é um fator importante para garantir a operação segura da rede inteligente. Quer sejam transformadores, cabos de alimentação, ou outro equipamento de energia, como componentes importantes do sistema de energia, eles podem causar superaquecimento local ou faíscas devido a alguns problemas no circuito ou fatores externos, levando a incêndios e causando perdas à produção e à vida das pessoas. Portanto, para evitar um evento tão maligno, é urgente realizar um monitoramento abrangente da temperatura dos equipamentos de energia. Para túneis de cabos usados para acomodar um grande número de cabos colocados em suportes de cabos em corredores ou estruturas de túneis, a temperatura ambiente e as condições de operação do cabo só podem
Quando ocorre um mau funcionamento, verifica-se que quanto maior o tempo de operação, mais propenso é a superaquecimento e acidentes com queimaduras, que pode causar enormes perdas económicas.
Aplicação de sistema distribuído de medição de temperatura de fibra óptica em sensores de temperatura de fibra óptica
Os sensores eletrônicos de temperatura existentes usam medição de temperatura do tipo ponto, which is prone to electromagnetic interference and is not suitable for strong electromagnetic scenarios, while fiber optic temperature sensors are not affected by electromagnetic interference and are very suitable for temperature monitoring in power systems. Fiber optic temperature sensors include single point temperature sensors and quasi distributed fiber optic temperature sensors. A single point temperature sensor measures a certain point in the temperature field with high measurement accuracy and reliability, but it is difficult to measure the distribution of multiple points in the temperature field. To solve the measurement problem of temperature field multi-point distribution, a quasi distributed sensor de temperatura de fibra óptica composed of a multiplexed fiber optic temperature sensor and an array of fiber optic temperature sensors has emerged. The quasi distributed fiber optic temperature sensor uses a single point fiber optic sensor array to form a spatial network distribution, achieving distributed fiber optic temperature measurement.
Distributed fiber optic thermometer is an optical time-domain temperature monitoring system, which is a widely used distributed fiber optic temperature measurement system both domestically and internationally. The system consists of a temperature measurement host, temperature sensing fiber optic, and DTS backend analysis software.
The distributed temperature measurement fiber optic system is based on the principle of Raman scattering in light, integrating optical time-domain reflection (OTDR) technology and the temperature sensitive characteristics of scattered light. It detects temperature changes at different positions along the fiber optic and achieves truly distributed measurement through intelligent analysis of DTS backend software data. It can continuously measure the temperature at any point along the fiber optic.
