Why do switch cabinets use fluorescent fiber optic temperature measurement

In the rapid development of electrical power in the new era, the stability of power equipment is closely related to people’s lives, so there are higher requirements for the stable operation of power equipment such as switchgear and dry-type transformers. The temperature of high-voltage electrical equipment within the normal range is an important aspect of whether the switchgear and other equipment are operating normally, and it is also a reason why switchgear equipment is more prone to failure. Therefore, the online temperature monitoring system for high-voltage electrical equipment must have good insulation, high-precision accuracy, fast response capability, and strong anti-interference ability.

What are the advantages of fluorescent fiber optic temperature sensors

Compared with the current mature temperature measurement methods, such as poor temperature stability, susceptibility to oscillation and magnetic field effects, fluorescent fiber optic temperature sensors have obvious advantages such as anti electromagnetic interference ability, good stability, high sensitivity, miniaturization, light weight, and contact temperature measurement. Therefore, fluorescent fiber optic thermometers are used for online monitoring of electrical equipment switchgear. High voltage switchgear is an important equipment for maintaining the normal operation of power systems. Its main functions include: opening or closing lines, exiting faulty equipment or current, and switching power loads. There are opening and closing structures inside, and the contacts of these opening and closing structures will experience severe wear and tear at the corresponding positions due to long-term mechanical closure, resulting in increased resistance and rapid temperature rise at the contacts, which can easily cause damage to electrical equipment and even lead to fires in severe cases. In 2003, an explosion occurred in one of the switchgear cabinets of a power company due to overheating, causing the 50 iron smelting blast furnaces in operation to stop running, resulting in direct economic losses of tens of millions of yuan. Therefore, real-time online temperature monitoring of high-voltage switchgear is imperative..

Online monitoring system for fluorescence fiber thermometer

The online monitoring system based on fluorescence fiber temperature measurement utilizes the advantages of fluorescence fiber thermometer, based on the efficient and intelligent programming language C #, combined with the internal structure and operating characteristics of the switchgear, to design and implement a temperature online monitoring system, ensuring the accuracy of temperature values and improving the real-time performance of online monitoring. This system can simultaneously monitor the temperature of multiple contacts inside the switchgear, increasing the monitoring range and providing the most direct temperature data for further improving the intelligent diagnostic system. It has good market prospects and application value.
