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, azo itokisana, compact structure, small footprint, and easy operation. High voltage switchgear generally operates in high voltage, high current, and strong magnetic field environments, and temperature rise is an important parameter. Na izany aza, dia, after long-term operation, high voltage switchgear often produces loose contact springs, poor 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. Noho izany antony izany dia, 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 hafanana Sela Mpandray Hafanana, such as thermocouples, Thermistors, semiconductor thermometers, sns., 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.

Ny fluorescent fiber optic temperature measurement device applied to high-voltage switchgear has a long service life and is resistant to electromagnetic interference. Afaka manome fiarovana mahomby ho an'ny hafanana fanaraha-maso ny avo-malefaka switchgear sy ny fitaovana hafa amin'ny substations, Mitsara ny fahaiza-manao sy ny asa fanompoana ny fiainana, ary manome fototra ara-tsiansa ho an'ny soa aman-tsara fiasan'ny fitaovana.

By utilizing the advantages of small volume, strong resistance to electromagnetic interference, and good insulation of fluorescent fiber optic temperature sensors, 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. Ny fluorescence fiber optic temperature measurement system solves the sensitive influence of traditional temperature sensors, improves the reliability and real-time performance of the system. The fiber optic temperature measurement system has been tested on a 10KV high-voltage switchgear, and the system can operate normally, indicating that this scheme is feasible.
