Abstract
An online monitoring system for electric node temperatures relates to the monitoring-device technology field and is characterized in that the online monitoring system comprises an equipotential wireless-sensing monitoring probe, a communication base station and a monitoring center. The equipotential wireless-sensing monitoring probe is arranged on a detected electric node and comprises a digital temperature sensor. The monitoring probe collects the real time temperature of the electric node by the digital temperature sensor. The real time temperature is sent to a receiving base station in a wireless communication manner and is transmitted to the monitoring center by the Ethernet, thereby solving an electric isolation problem of data transmission. The online monitoring system for the electric node temperature is safe and reliable in operation and is instead of conventional manual-inspection test means by which an electric power department detects a heating temperature of the electric-device node in substation operation for a long time, thereby greatly raising a safety operation level of the substation, preventing and reducing accident generation and bringing significant social benefit and economic benefit.

2, thermal infrared thermometry:
Comprise infrared temperature-measuring gun, far infrared imagery instrument etc. belong to contactless temperature-measuring.Advantage is that measurement range is large, and accuracy is higher, and reliability is better.Shortcoming is apparatus expensive.And need a large amount of manpowers regularly to patrol survey, can't realize the real time on-line monitoring of temperature.And the position of the equipment such as isolating switch dynamic/static contact of the handcart switch cabinet inside of using in a large number at present is hidden, and infrared thermometer can't carry out thermometric.In addition, infrared thermometer must be avoided the background interference of sunshine, generally needs in night or overcast and rainy measurement.
3, optical fiber grating temperature-measuring technology:
As temperature sensor, be installed in the surface of charged object with lenticular lenses, be connected with optical fiber between temperature measurer and temperature sensor.It is to utilize the linear relationship of reflection wave wavelength and temperature to realize the measurement of temperature.Shortcoming is that optical fiber is easy to break, easily broken, non-refractory.Although itself insulate optical fiber, behind the accumulation dust, insulating property are reduced, cause the optical fiber creeping discharge.This will have a strong impact on security of operation, and the Installation and Debugging workload is large, and cost is high, and the price of a spectroanalysis instrument is more than 100,000.
