The best method for online monitoring of node temperature in switchgear

The reliability and practicality of real-time monitoring of temperature at important nodes in switchgear are crucial. The trend of online monitoring of temperature at important nodes in switchgear is the development of passive optical sensors. Among them, the temperature sensor under the technology of fluorescent fiber optic temperature measurement is an important means of online monitoring of temperature at cable joints and circuit breakers in switchgear, based on its high cost-effectiveness, reliability, and practicality. Compared to previous temperature sensors, fluorescence fiber optic temperature measurement technology has strong anti-interference ability, can quickly respond and transmit temperature related data information, allowing staff to accurately control temperature values, facilitating subsequent operations and adjustments.

Infrared temperature measurement was an important method for detecting the temperature of switchgear in the past. However, due to the high voltage inside the high-voltage switchgear, the electromagnetic interference caused by it reduces the accuracy of temperature measurement. Excessive measurement points can significantly increase the difficulty of temperature measurement, and the working environment of some equipment can also have adverse effects on infrared temperature measurement. With the continuous development of technology, the use of fiber optic technology in various industries has become more mature. When measuring equipment temperature, fiber optic sensing methods have been more widely used. When facing problems such as large workload and a large number of monitoring nodes, fiber optic temperature measurement has strong practical value. Therefore, this article proposes fluorescence fiber optic temperature measurement technology to improve the efficiency, reliability, and safety of real-time monitoring of important node temperatures in switchgear.
