On-line temperature monitoring device for high-voltage electric equipment

The invention discloses an on-line infrared temperature monitoring device, which is characterized in that infrared temperature probes arranged on each temperature monitoring point by groups are connected with respective temperature signal collectors in a bus mode; each temperature signal collector is in networking connection with a computer; the computer is communicated with a plurality of signal collectors in a polling communication mode; the collected temperature signal is subjected to real-time display and data storage and is conveyed to a GSM (global system for mobile communications) or GPRS (general packet radio service) modulator demodulator; and the GSM or GPRS modulator demodulator is conveyed to a remote mobile phone in a wireless communication mode to be displayed or alarmed. The on-line temperature monitoring device for high-voltage electric equipment is especially suitable for unattended transformer substations, not only the automated monitoring level can be improved, but also the fire hazard accident occurrence rate of the equipment can be greatly lowered.
