Sensor is monitored in real time to the operation conditions of key equipment, and temperature exactly wherein needs one of significant data detected.It is logical
The normal normal temperature rise of power equipment mainly due to operating power equipment by electric current in alternating electromagnetic field it is caused various
Loss.But easily there is fastening bolt loosening in During Process of Long-term Operation in all kinds of power equipments, contact surface oxidation burn into touches
Point and the problems such as the aging of busbar junction, causes contact resistance to increase, the increase of load current loss power, cause hot-spot,
Temperature raises, and makes the security performance of power equipment by strong influence.So implement the online temperature detection of power equipment,
Equipment fault is found in time before occurring and processing hidden danger, is to ensure electric power safety operation, build the important ring of intelligent grid.
Existing temperature measurement on-line device (hereinafter referred to as device), mainly passes through battery powered.During battery powered, due to electricity
The temperature in use in pond, when temperature measurement on-line device collecting temperature is in more than 70 degrees Celsius, there is battery all below 70 degrees Celsius
The danger of blast.Also partial devices power taking by the way of opto-electronic conversion, the principle of opto-electronic conversion power taking are to utilize light etc.
Luminous energy is changed into electric energy by the light that illuminator irradiates by photoelectric conversion devices such as silicon photocells, and this mode power taking lacks
Point is that photoelectric transformation efficiency is low, and affected by environment big, just can not power taking when photoelectric conversion device superficial dust or when blocking
.Also have in addition and use surface acoustic wave thermometric, due to this technology and immature, the signal cross-talk between device is big, and thermometric is forbidden
Really.
