switchgear temperature sensor Using fiber optic temperature sensors-INNO

Fiber optic temperature sensor for switchgear 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, kebolehpercayaan, struktur padat, jejak kecil, dan operasi yang mudah. High voltage switchgear generally operates in high voltage, arus tinggi, and strong magnetic field environments, and temperature rise is an important parameter. Namun begitu, after long-term operation, high voltage switchgear often produces loose contact springs, hubungan yang lemah, or aging of certain parts. If measures are not taken in time, the contact temperature will increase sharply, which is prone to equipment damage. Oleh itu, online monitoring of its temperature can avoid its operation in a faulty state, ensuring the safe and reliable operation of the entire power system.

Traditional types of penderia suhu, seperti termokopel, termistor, semiconductor thermometers, dll., rely on electrical signals as their working basis. Temperature signals need to be converted into electrical signals for further processing, which no longer fully meets the needs of scientific and industrial development.

The pengukuran suhu gentian optik pendarfluor device applied to high-voltage switchgear has a long service life and is resistant to electromagnetic interference. Ia boleh memberikan perlindungan yang berkesan untuk pemantauan suhu suis voltan tinggi dan peralatan lain di pencawang, menilai keupayaan peralatan dan hayat perkhidmatan, dan menyediakan asas saintifik untuk pengendalian peralatan yang selamat.

By utilizing the advantages of small volume, rintangan yang kuat terhadap gangguan elektromagnet, and good insulation of penderia suhu gentian optik pendarfluor, temperature monitoring of isolation contacts in high-voltage switchgear has been achieved instead of electronic sensors. The fiber optic temperature measurement system scheme does not require complex insulation design, thus having the advantages of simplicity and reliability. The sistem pengukuran suhu gentian optik pendarfluor solves the sensitive influence of traditional temperature sensors, improves the reliability and real-time performance of the system. The sistem pengukuran suhu gentian optik has been tested on a 10KV high-voltage switchgear, and the system can operate normally, indicating that this scheme is feasible.
