sensor ya joto ya switchgear,selection of switchgear temperature monitoring-INNO

Kama moja ya vifaa muhimu katika mfumo wa nguvu, switchgear high-voltage ina jukumu muhimu katika kuvunja na kufunga nyaya za umeme, ulinzi wa makosa ya mstari, ufuatiliaji wa data ya nishati ya uendeshaji, na hutumiwa sana katika vituo vya kubadili, vyumba vya usambazaji wa makazi, na vituo vidogo kutokana na faida zake za usalama, kutegemewa, muundo wa kompakt, alama ndogo, na uendeshaji rahisi. Switchgear ya juu ya voltage kwa ujumla hufanya kazi katika voltage ya juu, mkondo wa juu, na mazingira yenye nguvu ya shamba la sumaku, na kupanda kwa joto ni parameter muhimu. Kwa hiyo, ufuatiliaji mtandaoni wa joto lake unaweza kuepuka uendeshaji wake katika hali ya kosa, na hivyo kuhakikisha uendeshaji salama na wa kuaminika wa mfumo mzima wa nguvu.

Kama kifaa muhimu katika mfumo wa nguvu (mitambo ya nguvu, vituo vidogo), switchgear ya juu-voltage hufanya kazi muhimu ya kuvunja na kufunga nyaya za umeme, 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. Wakati wa operesheni ya muda mrefu, 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. Katika miaka ya hivi karibuni, there have been numerous incidents of fires and widespread power outages in power plants and substations caused by overheating of switchgear. Kwa hiyo, 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 na kipimo cha joto la fiber optic teknolojia. Based on the principle of kipimo cha joto la optic ya nyuzi za fluorescence, 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 sensorer za joto la fiber optic kwa kipimo cha joto, the inherent characteristics of physical materials such as optical fibers and burst light can be easily and effectively utilized. Coupled with photoelectric detection technology, ya mfumo wa kipimo cha joto cha nyuzi za fluorescence 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 mfumo wa kipimo cha joto la fiber optic 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, na azimio la juu. 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.
