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, reliability, compact na istraktura, maliit na bakas ng paa, at madaling operasyon. High voltage switchgear generally operates in high voltage, mataas na agos, at malakas na kapaligiran ng magnetic field, and temperature rise is an important parameter. Gayunpaman, 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. Samakatuwid, 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 temperature sensors, such as thermocouples, mga thermistor, mga thermometer ng semiconductor, atbp., 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.

Ang fluorescent fiber optic temperature measurement 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, strong resistance to electromagnetic interference, and good insulation of fluorescent fiber optic na mga sensor ng temperatura, 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. Ang fluorescence fiber optic na sistema ng pagsukat ng temperatura solves the sensitive influence of traditional temperature sensors, improves the reliability and real-time performance of the system. Ang 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.
