Advantages of fiber optic temperature sensors for switchgear-INNO

Dalam klasifikasi sensor suhu dan sensor serat optik, sensor suhu serat optik adalah jenis perangkat sensor. Prinsip sensor suhu serat optik adalah mengembangkan sensor berdasarkan prinsip bahwa sumber cahaya yang diserap oleh berbagai zat juga akan berubah seiring suhu. Dengan menganalisis spektrum yang ditransmisikan oleh serat optik, Suhu real-time dari objek yang diukur dapat diperoleh. Tiga jenis utama sensor suhu serat optik adalah Serat Optik Terdistribusi sensor suhu, Sensor suhu kisi serat optik, dan sensor suhu fluoresensi serat optik. Yang paling hemat biaya yang dapat diterapkan pada switchgear adalah sensor suhu serat optik neon.

FJINNO secara mandiri mengembangkan berbagai sensor suhu serat optik, yang banyak digunakan dalam berbagai bidang seperti sistem industri kabel listrik, Aerospace, minyak bumi dan petrokimia, jembatan dan bendungan. Selain sensor suhu serat optik, common ones include fiber optic strain sensors, fiber optic displacement sensors, fiber optic grating tension sensors, and fiber optic pressure sensors.

What are the advantages of fiber optic temperature sensors

The temperature monitoring technology of fiber optic temperature sensors has important practical applications in the field of industrial temperature measurement. The main practical reason is that the fiber optic sensor transmitter has the characteristics of small volume, ringan, isolasi listrik yang tinggi, certain degree of bending, ketahanan korosi, rentang pengukuran suhu yang luas, and fast sensitivity response, which play a role in expanding and improving the PT100 temperature sensor, allowing traditional temperature sensors to play a complementary role in temperature measurement applications. In addition to the above advantages, fiber optic sensing technology is used in temperature measurement systems. Compared with infrared temperature measuring instruments or wireless temperature measuring instruments, it also has significant characteristics such as fast response, wide temperature measurement field, explosion-proof fiber optic temperature measurement, non flammable and explosive, and anti electromagnetic interference.

Merek dari Sensor Suhu Serat Optik

Fjinno, a domestic fiber optic temperature sensor brand company, has independently developed multiple fiber optic temperature sensors with advanced quality and performance, which are applied in different temperature control fields. The latest fiber optic temperature sensors are very suitable for measuring temperature in extreme environments, focusing on the IF-C model fiber optic temperature sensor, as well as special fiber optic temperature sensors developed specifically for measuring dangerous environmental temperatures that conventional temperature sensors cannot achieve.

Application of system components for fiber optic temperature sensors in switchgear

The main equipment of power companies includes switchgear, including temperature measurement of switchgear in nuclear power plants, temperature measurement of switchgear in photovoltaic power plants, and switchgear in substations. Because there are many components and accessories inside the switchgear, including many switches, instrument contacts, dll., which can generate temperature rise and emit significant heat, especially during peak loads and high temperatures in summer. The existing heat dissipation measures for switchgear mainly involve setting up heat dissipation holes on the cabinet body. There are many drawbacks to heat dissipation holes. Di satu sisi, they cannot truly quickly reduce the temperature of the switchgear, dan di sisi lain, they are prone to causing dust and other biological effects, including the invasion of rainwater on rainy days. The electrical equipment inside the switchgear may not be properly implemented due to the temperature rise standards of the switchgear, or short circuits may be caused by water stains, which will reduce the service life of the switchgear and cause more serious safety hazards. Jadi, we have independently developed and produced a switchgear temperature monitoring system to ensure that the switchgear is used under normal temperature rise.

Apa konsekuensi dari peningkatan suhu switchgear

Dalam situasi saat ini dimana konsumsi listrik perusahaan listrik meningkat dan jumlah switchgear semakin meningkat, switchgear mudah dioperasikan di bawah beban tinggi untuk waktu yang lama. Alasan utama peningkatan suhu pada switchgear adalah karena sakelar pisau internal dapat menyebabkan panas berlebih selama penggunaan jangka panjang karena oksidasi atau kontak yang lemah., dan operasi beban tinggi. Alasan mengapa suhu mudah naik adalah karena switchgear merupakan struktur yang tertutup sepenuhnya, yang seringkali menyulitkan pemeriksa peralatan listrik biasa untuk mendeteksi saklar pisau yang terlalu panas. Jadi, setelah saklar pisau terlalu panas dalam waktu lama, it is easy to cause the contact parts of the switch to burn out, causing large-scale power outages of the switchgear equipment, thereby increasing the likelihood of the switchgear being burned out and exploded.

Temperature monitoring system for switchgear

The temperature monitoring system for switchgear mainly includes: switchgear body, Sensor Suhu Serat Optik, pemancar suhu serat optik, menampilkan, serat optik fluoresen, dll. The temperature monitoring system for switchgear mainly monitors the temperature inside the cabinet through temperature sensors and transmits it to the controller and alarm. The output of the controller is connected to the fan. Di satu sisi, the temperature inside the cabinet is controlled by the fan, dan di sisi lain, alarm information is displayed through the alarm device, achieving the integration of temperature control and monitoring, and overall improving the automation level of the switchgear.
