With the continuous development and progress of temperature measurement technology, fiber optic temperature measurement systems are also constantly improving their stability and reliability, intrinsic safety, long-term reliability, immunity to electromagnetic interference, high temperature measurement accuracy, real-time online and other advantages, which will make their application prospects even broader. So what are the application scopes? Let’s take a look with FJINNO:

Zastosowanie Fluorescent Fiber Optic Temperature Measurement System

1. Power switchgear contacts, busbars, Linie przychodzące i wychodzące, itd

High voltage switchgear is a commonly used equipment in substations, with a large number of wires and joints between wires inside. The high temperature and harsh working environment make it easy to cause equipment failures. One of the reasons for equipment failures in high-voltage switchgear is that the wire joints are not properly handled, such as virtual welding when the joints are welded or not fully tightened when the joints are tightened. When the load on the substation increases, especially during the high temperature and high electricity consumption seasons in summer, the joints may overheat or even burn through. The quality of joint processing is difficult to detect, usually only discovered after equipment failure, and once equipment failure occurs, the losses are very heavy. Więc, it is very important to track the contacts that are prone to heating.

2. Dry type transformer temperature measurement and oil immersed transformer temperature measurement

The introduction of fluorescent fiber temperature measurement technology into transformers has achieved online monitoring of the internal temperature of transformers, which can monitor and locate hot spot temperatures in real time, greatly improving the sensitivity and reliability of detection. The transformer fiber optic winding temperature online monitoring system can directly, real-time, and accurately measure the winding temperature, achieve internal temperature monitoring of transformers, accurately measure the temperature of transformer windings, control the fan cooling system in real time, greatly extend the service life of power equipment transformers, ensure power supply during peak loads, and minimize unplanned or sudden accidents.

3. Industrial microwave fluorescence fiber optic temperature measurement

The microwave temperature measurement system using fluorescent fiber optic temperature measurement utilizes the immunity of fiber optic fluorescence temperature measurement to electromagnetic radiation fields to accurately measure the temperature of objects to be heated inside the microwave cavity in environments with ultra-high frequency, strong electromagnetic fields, and heavy interference; And accurate temperature measurement was achieved through the probe of the fluorescent temperature sensor. Fiber optic temperature measurement systems are suitable for integrated single channel or multi-channel temperature measurement, while fluorescent fiber optic temperature measurement equipment is particularly suitable for high-frequency and microwave devices.
