switchgear temperatura sensor,pagpili ng 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, proteksyon ng line fault, monitoring operating energy data, and is widely used in switch stations, residential distribution rooms, and substations due to its advantages of safety, pagiging maaasahan, compact na istraktura, maliit na bakas ng paa, at madaling operasyon. High voltage switchgear generally operates in high voltage, mataas na agos, at malakas na kapaligiran ng magnetic field, and temperature rise is an important parameter. Samakatuwid, 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, mga substation), 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. Sa panahon ng pangmatagalang operasyon, 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. Sa mga nakalipas na taon, there have been numerous incidents of fires and widespread power outages in power plants and substations caused by overheating of switchgear. Samakatuwid, 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 at pagsukat ng temperatura ng fiber optic teknolohiya. Based on the principle of Ang pagsukat ng temperatura ng fluorescence fiber, 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 mga sensor ng temperatura ng fiber optic para sa pagsukat ng 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, ang fluorescence fiber optic na sistema ng pagsukat ng temperatura can operate normally in harsh environments with strong electromagnetic interference, especially in high-voltage switchgear. Maaari itong makamit ang tumpak na kontrol at pagsukat ng panloob na temperatura ng katawan ng tao, at may mataas na katumpakan at mahusay na katatagan. Ang biglang liwanag Sistema ng pagsukat ng temperatura ng hibla karaniwang gumagamit ng quartz fiber optic bilang sensing probe at transmission medium. Sa pamamagitan ng modulasyon ng optical signal, mababa ang signal amplitude loss, at mayroon itong mga katangian ng mataas na sensitivity, mataas na tugon, at mataas na resolusyon. Maaari rin itong magpadala ng signal sa mga lugar na malayo sa malupit na on-site na kapaligiran, tinitiyak ang matatag na operasyon ng mga optoelectronic na aparato at lubos na binabawasan ang epekto ng kapaligiran sa pagsukat ng temperatura. Sa ilang mga espesyal na pangyayari, ang mga optical fiber ay maaaring angkop na baluktot upang magpadala ng mga optical signal, ginagawang angkop ang mga ito para sa on-site na pag-install at paggamit.
