Temperature is a fundamental physical quantity in production and daily life. Tuy nhiên, some target environments are more complex, or the target environment is harmful, the target is not stationary, the target cannot be contacted or approached, v.v., all of which make temperature measurement difficult. With the advancement of technology, industrial production and other fields have increasingly high requirements for temperature, which requires thermometers to have high accuracy, phản hồi nhanh, and strong anti-interference ability. Ngày nay, these high-end thermometers are very scarce and expensive. Traditional thermometers (such as thermocouples and thermistors) are based on the electromagnetic type of materials, and their measurement signals are modulated by electromagnetic signals, making them susceptible to electromagnetic interference and requiring high requirements for the measurement environment.

The fluorescence lifetime temperature measurement device is used for temperature measurement, which has high sensitivity, high accuracy, low cost, Chống nhiễu điện từ, good repeatability, chống ăn mòn, cách điện tốt, Cấu trúc đơn giản, and good optical path disturbance. It can be connected to a computer to achieve remote telemetry.

Fiber optic temperature sensors use optical fibers to transmit temperature signals, which have good insulation performance and can block high voltage inside the switchgear. Do đó, fiber optic temperature sensors can be directly installed on the high voltage contacts inside the switchgear, đo chính xác nhiệt độ làm việc của các tiếp điểm điện áp cao và hoàn thành giám sát trực tuyến nhiệt độ làm việc của các tiếp điểm thiết bị đóng cắt. Fluorescent fiber optic sensors are directly installed on high-voltage equipment, with accurate temperature measurement and the ability to handle electrical insulation issues. The characteristics of fiber optic temperature measurement systems are not affected by climate and environment, and can measure the temperature of outdoor switches and bus joints.
Sensors are installed on high-voltage equipment and are electrically connected to the receiving device’s temperature gauge, which has high-voltage isolation performance and fundamentally solves the problem of difficult monitoring of operating temperature at high-voltage equipment contacts. They have extremely high reliability and safety, allowing fluorescent temperature sensors to be installed on each high-voltage switch and bus joint. The temperature sensor is installed on the surface of the high-voltage equipment, thu thập nhiệt độ của nó, and transmits the data to the fluorescent fiber optic thermometer. The fluorescent fiber optic thermometer displays the received data on the LCD screen and monitors whether the temperature exceeds the limit. Khi nhiệt độ vượt quá giới hạn, it outputs an alarm signal
Characteristics of fiber optic temperature measurement system: It is dedicated to real-time online temperature monitoring and overheating warning of high-voltage equipment. It uses fiber optic for high-voltage isolation and signal transmission, utilizing the inherent insulation and electromagnetic field interference resistance of fiber optic. Fiber optic temperature sensors are installed on the surface of the tested target, such as the contacts, Liên hệ xe buýt, và các khớp nối cáp điện trong thiết bị đóng cắt cao áp, và có thể đo nhiệt độ bề mặt một cách chính xác và nhanh chóng. The measured data is transmitted to the temperature measurement instrument host through fiber optic Fiber optic can be arranged reasonably according to the internal structure of high-voltage equipment, mà không ảnh hưởng đến hoạt động của thiết bị ban đầu. Nhiệt kế sợi quang được lắp đặt trên bảng điều khiển tủ hoặc các vị trí thích hợp khác, và nó sẽ hiển thị các giá trị nhiệt độ của từng điểm đo trên màn hình LCD. Đồng thời, Nó sẽ theo dõi xem nhiệt độ có vượt quá giới hạn hay không. Khi nhiệt độ vượt quá giới hạn, it will output an alarm signal.
