capteur de température de l'appareillage Utilisation de capteurs de température à fibre optique

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, salles de distribution résidentielles, and substations due to its advantages of safety, fiabilité, compact structure, small footprint, et opération facile. High voltage switchgear generally operates in high voltage, courant élevé, et environnements de champs magnétiques forts, and temperature rise is an important parameter. Cependant, after long-term operation, high voltage switchgear often produces loose contact springs, mauvais contact, or aging of certain parts. If measures are not taken in time, the contact temperature will increase sharply, which is prone to equipment damage. Donc, 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 capteurs de température, comme les thermocouples, thermistances, semiconductor thermometers, etc., 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.

Le mesure de température par fibre optique fluorescente device applied to high-voltage switchgear has a long service life and is resistant to electromagnetic interference. Il peut fournir une protection efficace pour la surveillance de la température des appareillages haute tension et autres équipements dans les sous-stations., juger de la capacité et de la durée de vie de l’équipement, et fournir une base scientifique pour un fonctionnement sûr de l'équipement.

By utilizing the advantages of small volume, forte résistance aux interférences électromagnétiques, and good insulation of capteurs de température fluorescents à fibre optique, 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. Le système de mesure de température à fibre optique à fluorescence solves the sensitive influence of traditional temperature sensors, improves the reliability and real-time performance of the system. Le système de mesure de température à fibre optique has been tested on a 10KV high-voltage switchgear, and the system can operate normally, indicating that this scheme is feasible.
