Abstract:

This paper proposed a non-contact area array temperature measurement method for monitoring the temperature of switchgear,and designed a set of temperature monitoring system for switchgear.The experiments show that the temperature sensitivity of the system reaches 0.01 ℃,which can effectively distinguish abnormal heating points in the measured area.In the field experiment of the switch cabinet,the effective identification of the abnormal operating state of the isolation switch is realized,which proves the feasibility and advanced nature of the surface array temperature measurement method of the switch cabinet.

Key words: switchgear, non-contact temperature measurement, area array temperature measurement, isolation switch
