Infrared temperature measurement system in substation
1、 Demand analysis
A large part of unpredictable accidents in substations are caused by aging or failure, and their performance is that the temperature before the accident is much higher than usual. Therefore, if you can grasp the temperature of the equipment when it is working, you can predict before the accident and take effective measures in advance to reduce the loss to.
2、 Working principle
The substation infrared temperature measurement system uses the infrared detector to receive the infrared radiation energy distribution graph and reflect it on the photosensitive element of the infrared detector. The opto mechanical scanning mechanism scans the infrared thermal image of the measured object and focuses on the unit to display the infrared thermal image. Timely find and locate potential problems of power network equipment. This non-contact monitoring and measurement method is not affected by various complex factors, which reduces the risk of manual inspection and improves the monitoring and monitoring efficiency of the substation.
