Als eines der wichtigen Geräte im Energiesystem, Hochspannungsschaltanlagen spielen eine wichtige Rolle beim Unterbrechen und Schließen von Stromleitungen, Leitungsfehlerschutz, Überwachung der Betriebsenergiedaten, und wird häufig in Schaltanlagen eingesetzt, Wohnverteilerräume, und Umspannwerke aufgrund seiner Sicherheitsvorteile, Zuverlässigkeit, kompakte Struktur, geringer Platzbedarf, und einfache Bedienung. Hochspannungsschaltanlagen werden im Allgemeinen mit Hochspannung betrieben, hoher Strom, und Umgebungen mit starkem Magnetfeld, und der Temperaturanstieg ist ein wichtiger Parameter. daher, online monitoring of its temperature can avoid its operation in a fault state, thereby ensuring the safe and reliable operation of the entire power system.

As an important equipment in the power system (Kraftwerke, Umspannwerke), high-voltage switchgear undertakes the important task of breaking and closing power lines, thereby achieving the functions of transmitting and switching power loads, and removing faulty equipment or lines from the power system, ensuring the safe and reliable operation of the power system. Im Langzeitbetrieb, the contact points or busbar connections inside the high-voltage switchgear may generate heat due to aging and excessive contact resistance. If the temperature changes of these heating points cannot be accurately monitored, it may ultimately lead to the occurrence of a fire. In den letzten Jahren, there have been numerous incidents of fires and widespread power outages in power plants and substations caused by overheating of switchgear. daher, real-time monitoring of the operating temperature of the contacts or busbar connections inside the fully enclosed high-voltage switchgear can detect and eliminate potential thermal faults early, ensuring the safe and reliable operation of the power system. Real time monitoring of the temperature of high-voltage switchgear equipment has become a key issue that urgently needs to be solved for the safe and reliable operation of power system equipment. It is an urgent need to improve the safety and reliability of power system equipment operation and save energy, as well as an inevitable requirement for the advancement of power production technology.

FJINNO independently owns high voltage switchgear temperature measurement Und faseroptische Temperaturmessung Technologie. Based on the principle of Fluoreszenzfaseroptische Temperaturmessung, it has developed and produced an online temperature monitoring system for high voltage switchgear based on fluorescence fiber optic temperature measurement method, and provided solution design solutions to different users. This scheme can effectively overcome the limitations of infrared radiation temperature measurement method applied to temperature measurement of high-voltage switchgear and the power supply difficulties of wireless sensor temperature measurement method. The hardware design process of the high-voltage switchgear temperature measurement system based on fluorescence fiber optic temperature measurement has been completed, and the corresponding system software has been developed according to the system functions.

By combining fluorescence with faseroptische Temperatursensoren zur Temperaturmessung, the inherent characteristics of physical materials such as optical fibers and burst light can be easily and effectively utilized. Coupled with photoelectric detection technology, Die Fluoreszenzfaseroptisches Temperaturmesssystem can operate normally in harsh environments with strong electromagnetic interference, especially in high-voltage switchgear. It can achieve precise control and measurement of internal temperature of the human body, and has high accuracy and good stability. The sudden light faseroptisches Temperaturmesssystem generally uses quartz fiber optic as the sensing probe and transmission medium. Through modulation of the optical signal, the signal amplitude loss is low, and it has the characteristics of high sensitivity, high response, und hohe Auflösung. It can also transmit the signal to places far away from harsh on-site environments, ensuring stable operation of optoelectronic devices and greatly reducing the impact of the environment on temperature measurement. In certain special circumstances, optical fibers can be appropriately bent to transmit optical signals, making them suitable for on-site installation and use.
