Fiber optic temperature measurement system for rectifier cabinet-INNO

Function of fiber optic temperature measurement system for rectifier cabinet

1. The on-site temperature measurement device collects real-time temperature information of the switchgear contacts, kabel, and voltage transformer coils. The use of fluorescent fiber optic temperature probes has extremely strong electromagnetic immunity, voltage resistance, and insulation performance. Sensitive temperature sensing, stable and reliable long-term operation. The temperature measurement accuracy can reach ± 1 ℃.

2. The system comes with sound and light alarms, dry contact output, and human-machine interface display of alarm information.

3. The backend monitoring software system displays real-time temperature information of each contact point in the current switchgear, real-time curves, and historical data storing temperature information of each contact point in the past month.

Using various diagnostic methods to analyze the health status of equipment, including analysis of all equipment parameter out of limit alarms and other judgment methods, to timely monitor the operation status of high-voltage switchgear. The system can automatically and manually generate various periodic reports, yang boleh dieksport dan dicetak. Laporan yang dieksport boleh diedit dan dilihat melalui perisian Excel. Pada masa yang sama, sistem ini mempunyai fungsi paparan lengkung suhu masa nyata dan sejarah, which can accurately reflect the real-time monitoring curve and the temperature change curve of the monitored object at a certain point during a certain period of time;

4. Detect temperature abnormality alarm

Over threshold alarm: When the temperature value is detected to exceed the threshold, an alarm can be triggered, and two levels of thresholds can be set;
Exceeding temperature difference alarm: Jika perbezaan suhu antara suhu tertinggi dan terendah dalam julat titik ujian tertentu melebihi nilai yang ditetapkan (ambang boleh ditetapkan), penggera akan dicetuskan;

Penggera kadar perubahan perbezaan suhu: Jika perubahan suhu melebihi nilai yang ditetapkan (threshold 19 can be set) dalam tempoh masa tertentu, penggera akan dicetuskan;

sistem penggera kerosakan: The system monitors the performance status of the fiber optic temperature measurement probe and the connection status of the fiber optic, menyedari diagnosis dan ujian diri, dan segera menggesa kerosakan sistem;

5. Mengesan anomali suhu, kegagalan sistem, dll., dan sistem akan secara automatik penggera untuk mencapai pemantauan tanpa pemandu.
