Sensores de temperatura de fibra óptica INNO ,Sistemas de control de temperatura.
El rango de medición especificado en el “Controlador electrónico de temperatura para transformadores” (JB/T7631-2016), que utiliza Pt100 como sensor de temperatura tradicional, solo se puede limitar a menos de 1000 V, y este sensor está hecho de material metálico, lo que supone un peligro para la seguridad. Por lo tanto, Las sondas y los cables del sensor de temperatura para medir la temperatura del devanado del transformador tienen requisitos más altos.
The fiber optic temperature measurement system for dry-type transformers uses a fluorescent fiber optic temperature sensor independently developed by Fuzhou INNO Technology as the temperature sensing element. Este elemento sensor de temperatura es inmune a las interferencias electromagnéticas y resistente a la alta tensión (100Distancia entre KV/fibra y cable a tierra de 0,4 m). La medición de temperatura de fibra óptica fluorescente resuelve por completo los posibles riesgos de seguridad de la fuente de medición de temperatura y mejora el nivel de seguridad de los transformadores. The fluorescent fiber optic temperature measurement system for dry-type transformers aims to achieve isolation and shielding from external electrical interference signals in the operating environment of dry-type transformers, including power supply, signal input, signal output, and temperature control box casing. Sin sustancias metálicas, Seguridad intrínseca. En respuesta a la vibración, polvo, humedad, aceite y otros entornos de trabajo in situ, Se toman medidas de protección multicapa para garantizar que el controlador de temperatura de fibra óptica tenga una buena compatibilidad electromagnética, Garantizar un funcionamiento estable y fiable.
Our company has actual application cases of fiber optic temperature measurement systems for dry-type transformers, which can be directly put into use.

The advantages of fluorescent fiber optic temperature sensors
Fluorescent temperature sensors belong to all optical measurement devices
Only optical signals without electrical signals are true passive probes.
High insulation and voltage resistance
The fluorescent fiber optic temperature sensor can withstand a power frequency voltage of 100kV.
Fluorescent optical fibers are inherently immune to electromagnetic interference
The accuracy of detection and the stability of data transmission are completely unaffected.
Strong anti pollution flashover ability
The fluorescent fiber optic sensor is covered with a jacket with strong stain resistance to ensure the safety of the system.Temperature sensitive materials have high reliability
The temperature sensing material of the temperature sensor is rare earth material, which has a long-term stability and has been successfully applied in equipment monitoring for over 30 years of service life.Accurate positioning measurement
The temperature sensing probe has a small volume and can accurately locate the installation position.
Temperature measurement cycle is less than, with high real-time performance
The temperature measurement cycle is less than 1 segundo, which can fully ensure the timeliness of the alarm.
