Why do substations use fluorescent fiber optic temperature measurement systems

Sensor de temperatura de fibra óptica, Sistema de monitoreo inteligente, Fabricante de fibra óptica distribuida en China

Una subestación es una instalación de energía en el sistema de energía que convierte el voltaje, Recibe y distribuye energía eléctrica, Controla el flujo de electricidad, y ajusta el voltaje. Como una base de conversión de energía muy importante, Si ocurre un incendio u otro accidente de energía en una subestación, Inevitablemente conducirá a cortes de energía a gran escala, causando impactos significativos y pérdidas en la producción de las empresas y en la vida de las personas. Por lo tanto, Garantizar la seguridad y fiabilidad de las subestaciones y evitar incendios es crucial. Entre ellos, El sobrecalentamiento de los equipos es un peligro oculto importante que puede provocar incendios en las subestaciones. Sobrecalentamiento en los contactos dinámicos y estáticos y otras conexiones de la aparamenta de alta tensión en las subestaciones, Empalmes de cables, Conexiones de cables, y la descarga parcial de cables de alta tensión son los principales peligros ocultos de los accidentes a gran escala. Además, Estos lugares a menudo tienen voltajes de varios miles o incluso decenas de miles de voltios, lo que representa un gran peligro de seguridad para que los operadores ingresen e investiguen.

Fluorescent fiber temperature measurement is based on the material properties of rare earth fluorescent substances to achieve temperature measurement. After being excited by light, a certain rare earth sensitive material emits fluorescence when the electron absorption photons in the sensitive material transition from low energy level to high energy level and return from high energy level to low energy level. The sustained fluorescence emission after the elimination of excitation light depends on the lifetime of the excited state, which usually decays exponentially. The decay time constant can be used to measure the lifetime of the excited state, which is called the fluorescence lifetime. The fluorescence lifetime depends on the temperature, and the biggest advantage of using this method for temperature measurement is good stability, no need for calibration, and long lifetime.

The sistema de medición de temperatura de fibra óptica de fluorescencia is installed at the bottom outlet of the object being measured. The system can monitor the temperature at the bottom of the object in real time and achieve rapid and accurate temperature measurement of the liquid being measured. The temperature detection speed of this temperature measurement system is fast, and it can reach the mS level at the fastest. The accuracy of temperature measurement is high, and it can achieve within ± 1 °C. It can effectively monitor the highest temperature of the chemical liquid of the measured object, making the reaction more accurate.

The fluorescence fiber optic temperature measurement system uses Medición de temperatura de fibra óptica, which is made of glass core and has good insulation properties. It can avoid interference from strong magnetic fields, high voltages, and large currents generated during transformer operation, enabling measurement esults are relatively accurate. The fluorescent fiber thermometer is installed in an explosion-proof box, which can prevent chemical explosions caused by instrument ignition and other factors. Por lo tanto, it can be used in chemical environments and has a wide range of applications.
