    Abstract: With voltage, current, frequency, power and temperature of medium-voltage switchgear as monitoring objects, this paper designed a set of on-line monitoring device taking single chip dsPIC as the core. The device collected voltage and current signals of switchgear with mutual inductors, testing current frequencies with frequency modules and collecting temperature signals of switchgears with infrared temperature sensors. This paper gave the hardware circuit design and software flow chart. The actual operation result shows that the device is with higher measurement accuracy, realizing non-contact temperature measurement for the equipment.
              Key words: switchgear; state monitoring; non-contact temperature measurement
