Đặc điểm của hệ thống đo nhiệt độ cho thiết bị đóng cắt

1. Positioning characteristics. The optical fiber of the system is not only a Cảm biến nhiệt độ 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. Khi xảy ra lỗi quá nhiệt, hệ thống có thể đưa ra cảnh báo và xác định chính xác vị trí quá nhiệt, thereby guiding maintenance work.

2. Đặc điểm phân bố. 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. Sự tiến bộ. 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, và set parameters such as temperature measurement khu vực, chiều dài, and alarm points through the Windows operating interface.

4. Sự chính xác. Độ phân giải nhiệt độ của hệ thống đạt 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. Tính linh hoạt. The system provides continuous dynamic monitoring signals and can achieve alarms through two settings: Trước hết, multi-level temperature point alarms can be set, chẳng hạn như báo động ban đầu lúc 30 °C, báo thức trước lúc 40 °C, và các biện pháp được thực hiện tại 50 °C, và có thể được điều chỉnh theo các môi trường khác nhau; 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. Khả năng mở rộng. 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 sợi quang.

7. Khả năng tương thích. The system can be interconnected with other intelligent measurement and control devices such as PC, fire alarm system, SCADA, v.v. through RS232 interface, built-in relay contacts, and other output forms. Trong ứng dụng phòng cháy chữa cháy, 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. Bảo vệ. Các hệ thống has a security record function, which can store all historical data since the system was running. Nếu sợi quang bị hỏng, 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 – sợi quang.
