Why do 10kV switchgear in substations need temperature measurement-INNO

長期稼働時, the contact parts of isolation switch contacts, switch contacts, conductive busbar connections, and cable head connections are prone to increased contact resistance due to surface oxidation corrosion, loose fastening bolts, その他の理由, which can cause heating and electrical corrosion of the contact parts. 重症の場合, it can melt the connecting components and cause short circuit faults, resulting in widespread power outages, reduced system power supply reliability, そして重大な経済的損失. Preventing heating faults in 10kV switchgear is an important issue that the substation operation department needs to face in the long term. Prevent overheating of the current carrying circuit of switchgear; Regularly use temperature measuring equipment to check the joints of switchgear and the conductive parts of isolating switches (key parts: 連絡先, outlet sockets, 等), especially during heavy loads or high temperatures, and strengthen monitoring of the temperature rise of operating equipment. Timely measures should be taken when problems are discovered.

の fluorescent fiber online temperature measurement system effectively solves the shortcomings of using temperature wax monitoring, handheld infrared temperature measurement, wireless temperature measurement and other methods in switchgear, greatly improving the equipment heating operation and maintenance management level of the substation operation department. It can effectively prevent equipment accidents caused by heating at the contact parts of the equipment, and also liberate the operators from the heavy and inefficient 温度測定 and inspection work of switchgear, greatly improving work efficiency. This technology can be applied not only to temperature measurement in switchgear, but also to temperature measurement of other primary equipment such as main transformers, capacitors, 原子炉, サーキットブレーカー, and isolating switches in substations. It has a wide range of applications and great practical promotion value, which has a positive promoting effect on the development of temperature measurement technology in substations.
