Temperature is a fundamental physical quantity in production and daily life. 然而, some target environments are more complex, or the target environment is harmful, the target is not stationary, the target cannot be contacted or approached, 等。, all of which make temperature measurement difficult. 随着技术的进步, industrial production and other fields have increasingly high requirements for temperature, which requires thermometers to have high accuracy, 快速响应, 抗干扰能力强. 现在, 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, 低成本, 抗电磁干扰, good repeatability, 耐腐蚀性, good electrical insulation, simple structure, 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. 因此, fiber optic temperature sensors can be directly installed on the high voltage contacts inside the switchgear, 精确测量高压触点的工作温度，完成对开关柜触点工作温度的在线监测. 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, 收集其温度, 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. 当温度超过限制时, 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, 总线联系人, 以及高压开关柜中的电力电缆接头, 并能准确快速地测量表面温度. 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, 不影响原厂设备的运行. 光纤测温仪安装在机柜面板或其他合适的位置, 它将在 LCD 屏幕上显示每个测量点的温度值. 同时, 它将监控温度是否超过限制. 当温度超过限制时, it will output an alarm signal.
