Fluorescent fiber optic temperature measurement device for power equipment

With the implementation of power grid renovation, especially the continuous deepening of urban network renovation and construction, the usage of cables and electrical equipment has significantly increased, which has made the operation management, monitoring and maintenance of cables and electrical equipment very important. In practical work, in order to avoid cables and electrical equipment from overheating at high temperatures, it is usually necessary to choose a method that appropriately preserves their load capacity. Echter, this makes the use of these cables and electrical equipment uneconomical, and manual inspections can only detect the surface temperature of the test point. For enclosed electrical equipment such as cables and switchgear, true temperature monitoring cannot be achieved. Of het nu vanuit het perspectief van de veilige werking van elektrische apparatuur zoals kabels en ringhoofdkasten is, of vanuit het perspectief van de planningsbehoeften van het stroomsysteem, real-time monitoring van het draagvermogen van kabels en elektrische apparatuur is vereist, Dit kan worden bereikt door online real-time monitoring van de temperatuur van de testpunten.

The reliability of high-voltage switchgear under high voltage and high current conditions is closely related to the temperature rise of the isolation switch contacts. During the operation of the power grid, mechanische trillingen, contact erosion, and other reasons can worsen contact conditions, verhoging van de contactweerstand, cause an increase in contact point temperature, exacerbate contact surface oxidation, and lead to local welding or arc discharge at loose contact points, ultimately causing damage to electrical equipment, power outages, or major accidents such as fires. This type of contact overheating fault accident is not only due to the quality problem of the high-voltage cabinet switch itself, but more importantly, due to the lack of effective monitoring methods for the temperature rise of the isolation switch contacts at present.

Over de werking van de contacttemperatuur in hoogspanningsschakelapparatuur en kabelaftakdozen, door te meten, toezicht houden, en het statistisch analyseren van de temperatuur van aftakdozen, schakelapparatuur of hoogspanningscontacten met behulp van fluorescerend glasvezelcontact, operators kunnen de werkomstandigheden van aftakdozen volledig begrijpen, schakelapparatuur of hoogspanningscontacten, en het voorkomen of verminderen van het optreden van fouten; De hoogspanningsstroom temperatuur meetsysteem heeft een goede betrouwbaarheid en complete functies.
