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, dakunan rarraba na zama, and substations due to its advantages of safety, reliability, m tsari, ƙananan sawun ƙafa, da sauki aiki. High voltage switchgear generally operates in high voltage, high halin yanzu, da kuma ƙaƙƙarfan yanayin filin maganadisu, and temperature rise is an important parameter. Duk da haka, 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. Saboda haka, 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, irin su thermocouples, thermistors, semiconductor ma'aunin zafi da sanyio, da dai sauransu., 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.

The mai kyalli fiber optic ma'aunin zafin jiki 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, juriya mai ƙarfi ga tsangwama na lantarki, and good insulation of Fiber optic zazzabi na'urori masu auna sigina, 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. The 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.
