Các fiber optic thermometer uses fiber optic transmission for temperature signals. Fiber optic has good insulation performance and can block high voltage inside the switchgear. Do đó, the fiber optic temperature sensor can be directly installed on the high voltage contacts inside the switchgear to accurately measure the working temperature of the high voltage contacts and complete online monitoring of the working temperature of the switchgear contacts.

Các wireless temperature measurement system uses electromagnetic waves to transmit signals, and the sensor is directly installed on the high-voltage equipment. The temperature measurement is accurate and can handle electrical insulation problems.

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 anti electromagnetic interference performance of fiber optic. The fiber optic temperature sensor is placed on the surface of the measured target, such as the contacts in the high-voltage switchgear, busbar contacts, and power cable joints, and can accurately and quickly measure its surface temperature, and transmit the measured data to the thermometer host through fiber optic Fiber optic cables can be wired reasonably according to the internal structure of high-voltage equipment, without affecting the operation of existing equipment. Fiber optic thermometers are installed on cabinet panels or other suitable locations, and they display the temperature values of each measured point on the LCD screen while monitoring whether the temperature exceeds the limit. When the temperature exceeds the limit, an alarm signal is output.

Both wireless temperature measurement and fiber optic temperature measurement have their own adaptation environments and characteristics, and cannot reflect the advantages and disadvantages of both in a one size fits all manner. Each temperature measurement product can be well applied in different places.
