switchgear temperature sensor Using fiber optic temperature sensors

Als een van de belangrijke apparatuur in het energiesysteem, Hoogspanningsschakelapparatuur speelt een belangrijke rol bij het onderbreken en sluiten van elektriciteitsleidingen, lijnfoutbeveiliging, monitoring van bedrijfsenergiegegevens, en wordt veel gebruikt in schakelstations, residentiële distributiekamers, en onderstations vanwege de voordelen op het gebied van veiligheid, betrouwbaarheid, compacte structuur, kleine voetafdruk, en eenvoudige bediening. Hoogspanningsschakelapparatuur werkt doorgaans op hoogspanning, hoge stroom, en omgevingen met sterke magnetische velden, en temperatuurstijging is een belangrijke parameter. Echter, after long-term operation, high voltage switchgear often produces loose contact springs, slecht kontakt, or aging of certain parts. If measures are not taken in time, the contact temperature will increase sharply, which is prone to equipment damage. Daarom, 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 temperatuur sensoren, zoals thermokoppels, thermistoren, semiconductor thermometers, enz., 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.

De fluorescente glasvezel temperatuurmeting device applied to high-voltage switchgear has a long service life and is resistant to electromagnetic interference. It can provide effective protection for temperature monitoring of high-voltage switchgear and other equipment in substations, judge the equipment’s ability and service life, and provide scientific basis for safe operation of equipment.

By utilizing the advantages of small volume, sterke weerstand tegen elektromagnetische interferentie, and good insulation of fluorescerende glasvezeltemperatuursensoren, 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. De fluorescentie glasvezel temperatuurmeetsysteem solves the sensitive influence of traditional temperature sensors, improves the reliability and real-time performance of the system. De glasvezel temperatuurmeetsysteem has been tested on a 10KV high-voltage switchgear, and the system can operate normally, indicating that this scheme is feasible.
