sensor de temperatura do painel,selection of switchgear temperature monitoring-INNO

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, confiabilidade, estrutura compacta, small footprint, and easy operation. High voltage switchgear generally operates in high voltage, alta corrente, e ambientes de campo magnético forte, and temperature rise is an important parameter. Portanto, 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 (usinas de energia, subestações), 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. Durante operação de longo prazo, 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. Nos últimos anos, there have been numerous incidents of fires and widespread power outages in power plants and substations caused by overheating of switchgear. Portanto, 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 e medição de temperatura de fibra óptica tecnologia. Based on the principle of medição de temperatura de fibra óptica de fluorescência, desenvolveu e produziu um sistema de monitoramento de temperatura on-line para painéis de alta tensão com base no método de medição de temperatura por fibra óptica fluorescente, e forneceu soluções de design de soluções para diferentes usuários. Este esquema pode efetivamente superar as limitações do método de medição de temperatura por radiação infravermelha aplicado à medição de temperatura de comutadores de alta tensão e as dificuldades de fornecimento de energia do método de medição de temperatura do sensor sem fio. O processo de design de hardware do quadro de distribuição de alta tensão sistema de medição de temperatura baseado em fibra óptica fluorescente a medição de temperatura foi concluída, e o software do sistema correspondente foi desenvolvido de acordo com as funções do sistema.

Ao combinar fluorescência com sensores de temperatura de fibra óptica para medição de temperatura, the inherent characteristics of physical materials such as optical fibers and burst light can be easily and effectively utilized. Coupled with photoelectric detection technology, o sistema de medição de temperatura de fibra óptica de fluorescência 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 sistema de medição de temperatura de fibra óptica 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, e alta resolução. 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.
