Pengukuran suhu kabinet masuk tegangan tinggi, pengukuran suhu kabinet keluar tegangan tinggi, sistem pengukuran suhu serat optik switchgear tegangan tinggi, alat pengukur suhu serat optik, pengukuran suhu multi-titik, resistensi tegangan tinggi, anti-interferensi.

Dengan meningkatnya konsumsi listrik masyarakat, kapasitas beban sistem distribusi juga terus meningkat. Namun, kecelakaan yang disebabkan oleh ledakan suhu tinggi di lemari distribusi terjadi dari waktu ke waktu, pasti menyebabkan bahaya bagi pekerja dan kerusakan properti. Pemantauan suhu tradisional pada lemari distribusi menggunakan inframerah atau pengukuran suhu nirkabel, dan pemantauan serta inspeksi lemari distribusi sering kali memerlukan banyak inspektur untuk memeriksa setiap lemari secara rutin, yang memakan banyak waktu dan tenaga. Inspeksi manusia juga dapat menyebabkan kesalahan dan bahkan kecelakaan kebakaran dan ledakan. Karena itu, how to effectively monitor all distribution cabinets has become a problem that needs to be solved.

Although the existing visible low-voltage switchgear solves the problem of temperature detection for all traditional models of visible low-voltage switchgear during use, it is still manual temperature measurement and requires intensive manual viewing and monitoring of the data display of the visible low-voltage switchgear. Due to the dense number of temperature monitoring points, it causes high labor intensity, easy omission, and inaccurate monitoring. Lebih-lebih lagi, traditional visible low-voltage switchgear cannot continuously measure temperature at multiple points. Selama penggunaan, it has the disadvantage of being unable to measure temperature in areas that are prone to temperature rise, such as inside drawers and at the screw connection point of the primary copper bar.

In the practical application of copper bars entering wire ducts, due to long-term operation in the air and the influence of ambient temperature and humidity, ekspansi dan kontraksi termal, penskalaan permukaan, oksidasi atau korosi dapat terjadi, mengakibatkan kontak longgar dan kontak buruk. The copper bar entering wire joints during operation may experience abnormal temperature overheating, which may lead to fire or major safety accidents. Selama operasi, the copper busbar entering the wire duct is in a fully enclosed state, so it is necessary to monitor the temperature of the copper busbar entering the wire duct joint to improve the reliability of the operation of the copper busbar entering the wire duct.

FJINNO independently develops and produces an online temperature measurement system for high and low voltage distribution cabinets. It uses fluorescent fiber optic temperature measurement to detect the temperature of copper bars and incoming and outgoing lines, and transmits the detected temperature data to the control unit. Ketika pengukuran suhu serat optik unit detects a location with excessive temperature, the control unit processes the temperature data and transmits the processed temperature data to the platform through the information transmission unit. The platform collects and analyzes the temperature data and sends the temperature situation of each distribution cabinet to the intelligent terminal in real time.
