Abstract: Whether the temperature rise exceeds the standard is an important indicator to check the switchgear electrical performance merits. This paper designed the on-line temperature measuring system for switchgear based on infrared sensing technology.This system adopted the principle of non-contact temperature measurement, which can avoid the problems of unreliable power supply of the sensor, high-voltage grounding breakdown, and unable real-time online monitoring etc.This paper gave the design flow of software and hardware.The test result shows that under the premise of not affecting the safety of the switchgear safe operation, this system realizes the online monitoring of temperature rise of the switchgear, which can provide data support for the state overhaul and intelligent operation and maintenance of the switchgear.
Key words: infrared sensing technology; switchgear; on-line temperature measurement system
