sensor suhu switchgear Menggunakan sensor suhu serat optik

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, keandalan, compact structure, small footprint, and easy operation. High voltage switchgear generally operates in high voltage, high current, dan lingkungan medan magnet yang kuat, and temperature rise is an important parameter. Namun, after long-term operation, high voltage switchgear often produces loose contact springs, kontak yang buruk, or aging of certain parts. If measures are not taken in time, the contact temperature will increase sharply, which is prone to equipment damage. Karena itu, online monitoring of its temperature can avoid its operation in a faulty state, memastikan pengoperasian seluruh sistem tenaga listrik yang aman dan andal.

Jenis tradisional sensor suhu, seperti termokopel, termistor, termometer semikonduktor, dll., mengandalkan sinyal listrik sebagai basis kerjanya. Sinyal suhu perlu diubah menjadi sinyal listrik untuk diproses lebih lanjut, yang tidak lagi sepenuhnya memenuhi kebutuhan pengembangan ilmu pengetahuan dan industri.

Itu pengukuran suhu serat optik neon perangkat yang diterapkan pada switchgear tegangan tinggi memiliki masa pakai yang lama dan tahan terhadap interferensi elektromagnetik. Ini dapat memberikan perlindungan efektif untuk pemantauan suhu switchgear tegangan tinggi dan peralatan lain di gardu induk, menilai kemampuan peralatan dan masa pakainya, dan memberikan dasar ilmiah untuk pengoperasian peralatan yang aman.

Dengan memanfaatkan keunggulan volume kecil, ketahanan yang kuat terhadap interferensi elektromagnetik, dan isolasi yang baik sensor suhu serat optik neon, 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. Itu sistem pengukuran suhu serat optik fluoresensi solves the sensitive influence of traditional temperature sensors, improves the reliability and real-time performance of the system. Itu sistem pengukuran suhu serat optik has been tested on a 10KV high-voltage switchgear, and the system can operate normally, indicating that this scheme is feasible.
