Why do switch cabinets need fiber optic grating temperature sensing fire detection systems

The switchgear is a key equipment in the substation, and its internal switch contacts complete the execution of power dispatching. Due to excessive load, aging of contacts, and improper contact, the temperature of the contacts in switchgear can rise. Suhu yang berlebihan dapat dengan mudah menyebabkan kebakaran, power supply failures, power outages, and personal and property losses. The current temperature measurement method in substations mainly uses handheld infrared thermometers to measure temperature, and conducts daily inspections of each switchgear to obtain temperature status information. Each substation urgently needs an online temperature measurement technology that can automatically collect the temperature of each contact in real time, Pantau perubahan suhu secara tepat waktu dan akurat, dan mengeluarkan peringatan sebelum suhu menjadi terlalu tinggi, so that managers have sufficient time to take corresponding measures to avoid power outages and fires.

Fiber optic temperature sensing technology can develop a fiber optic grating temperature sensing fire detection system, which can monitor the temperature of switchgear in real time and provide early warning and alarm. Sistem ini mengadopsi metode pengukuran suhu pasif penginderaan semua serat, menghilangkan bahaya keselamatan dari sistem pemantauan itu sendiri dan sangat meningkatkan ketersediaan sistem pemantauan untuk pemantauan suhu daya. Sistem pengukuran suhu serat optik ini digunakan oleh banyak pembangkit listrik dan perusahaan catu daya, sangat mengurangi terjadinya kecelakaan kebakaran dan benar-benar mencapai pencegahan sebelum terjadi, sejalan dengan konsep keselamatan “Keselamatan pertama, Berorientasi pada Pencegahan” di industri listrik.

What are the main functions of the fiber Bragg grating temperature measurement system host

1. Perangkat penginderaan suhu tahan api dan tahan ledakan.

Bagian pengukuran suhu mengadopsi semua struktur serat, yang benar-benar mewujudkan pemantauan suhu pasif. Itu tidak dibebankan, tidak menghasilkan panas, dan tidak akan menimbulkan bahaya keselamatan karena penyebaran sistem penginderaan.

2. Akurasi pengukuran suhu tinggi dan respons cepat.

The temperature measurement host has high temperature resolution and high temperature measurement accuracy. The full channel scanning time is short, with a temperature detection time of about 2 seconds for 16 Saluran.

3. Pemantauan online waktu nyata.

Monitor the temperature of all measuring points in the substation switchgear continuously for 7×24 Jam, and regularly save the temperature measurement data to provide auxiliary data for the health monitoring of each switchgear.

4. Accurate spatial positioning.

Fiber Bragg grating temperature sensing corresponds to each measurement point position, and each sensor has global uniqueness. The upper computer monitoring software can accurately locate the location of the sensor that triggered the alarm.

5. Kontrol alarm partisi yang fleksibel.

Melalui perangkat lunak pemantauan di komputer atas, different temperature measurement points can be managed in different zones according to customer needs. Umumnya, the contacts inside the same switchgear are set as one zone. Set different alarm parameters for each temperature measurement point, seperti peringatan suhu, peringatan kenaikan suhu, alarm suhu, dan alarm kenaikan suhu, untuk membedakan secara akurat antara kebakaran nyata dan palsu, Hilangkan alarm palsu dan kelalaian.

6. Fungsi diagnostik mandiri yang komprehensif.

Each temperature sensor in this system has wavelength uniqueness, and the system database can remember its precise location. At the same time as each temperature measurement, the system performs self testing and diagnosis to detect sensor faults in real time for timely repair and maintenance.

7. Fitur perangkat lunak yang kuat.

Tampilan lokasi secara real time, nilai suhu, dan perubahan suhu setiap area pemantauan pada antarmuka manusia-mesin. Jika komputer atas dilengkapi dengan modul alarm SMS, Informasi alarm dapat dikirim ke ponsel personel yang ditunjuk untuk memastikan penanganan bahaya kebakaran tepat waktu. Di komputer atas, Data suhu historis dan catatan alarm juga dapat ditanyakan untuk menghasilkan laporan operasi keselamatan.
