As one of the important equipment in the power system, high-voltage switchgear plays an important role in breaking and closing power lines, line fault protection, monitoring operating energy data, and is widely used in switch stations, residential distribution rooms, and substations due to its advantages of safety, מהימנות, compact structure, small footprint, and easy operation. High voltage switchgear generally operates in high voltage, high current, and strong magnetic field environments, and temperature rise is an important parameter. לכן, 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 (power plants, substations), 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. During long-term operation, 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. בשנים האחרונות, there have been numerous incidents of fires and widespread power outages in power plants and substations caused by overheating of switchgear. לכן, 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 and מדידת טמפרטורה בסיב אופטי טכנולוגיה. Based on the principle of fluorescence fiber optic temperature measurement, 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 חיישני טמפרטורה בסיב אופטי for temperature measurement, the inherent characteristics of physical materials such as optical fibers and burst light can be easily and effectively utilized. Coupled with photoelectric detection technology, the fluorescence fiber optic temperature measurement system 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 מערכת למדידת טמפרטורה בסיב אופטי 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, and high resolution. 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.
