Charakterystyka układ pomiaru temperatury rozdzielnic

1. Positioning characteristics. The optical fiber of the system is not only a czujnik temperatury but also a channel for information transmission. Due to its good insulation characteristics and flexibility, it can be directly laid on the surface or key parts of a live equipment to obtain real-time temperature data of the operating equipment. Gdy wystąpi błąd przegrzania, system może włączyć alarm i dokładnie zlokalizować miejsce przegrzania, thereby guiding maintenance work.

2. Charakterystyka dystrybucji. The system can continuously and dynamically monitor temperature changes at points every 2 meters within a range of several thousand meters, and can set temperature alarm values arbitrarily. The monitoring system host can carry multiple 2-kilometer-long optical fibers.

3. Postępowość. The system is the most effective means of online temperature monitoring in the power system, and has replaced traditional linear temperature sensing materials in foreign countries. It has become mature in technology. The monitoring system host can easily debug, program, i set parameters such as temperature measurement obszar, długość, and alarm points through the Windows operating interface.

4. Dokładność. Osiąga się rozdzielczość temperaturową systemu 0.1 ℃ and the temperature accuracy is ± 1 °C. The laser emission device inside the monitoring system host emits tens of thousands of light pulses per second and outputs the average sampled temperature to the display system, effectively eliminating random errors.

5. Elastyczność. The system provides continuous dynamic monitoring signals and can achieve alarms through two settings: Po pierwsze, multi-level temperature point alarms can be set, takie jak alarm początkowy o godz 30 °C, pre alarm at 40 °C, i środki podjęte o godz 50 °C, i można je dostosować do różnych środowisk; The second is to set a temperature change rate threshold based on the high temperature change rate before the accident occurs. When the temperature change rate is detected to be greater than this value, an alarm signal is issued and corresponding signal output is provided. The monitoring system immediately generates an alarm when one of these two alarm conditions is met. The monitoring system can adjust the sampling interval according to on-site requirements.

6. Skalowalność. The system can be extended to multiple optical fibers, and automatic optical path selection and measurement can be achieved by adding an optical path switching switch. The monitoring system can be expanded to a maximum of 8 światłowody.

7. Zgodność. The system can be interconnected with other intelligent measurement and control devices such as PC, fire alarm system, SCADA, itd. through RS232 interface, built-in relay contacts, and other output forms. W zastosowaniach przeciwpożarowych, it can also be connected to the fire alarm controller system to provide signals for alarm. The monitoring system can output signals in segments and levels according to different alarm zones, which can adapt to the needs of different control purposes.

8. Bezpieczeństwo. Ten system has a security record function, which can store all historical data since the system was running. Jeśli światłowód jest uszkodzony, the monitoring system can locate the damaged point and has a self diagnostic function. The monitoring system will not generate electromagnetic interference with power cables due to the use of optical signals and non-conductive media – światłowody.
