Above-mentioned antenna can be radio-frequency antenna.
It is above-mentioned to be provided with groove in one end of temperature-sensitive magnet.
Above-mentioned groove can be U-type groove.
The utility model reasonable and compact in structure, it is easy to use, designed using passive and wireless, overcome inside switch cabinet knot
The problem of structure complexity cabling difficulty, and directly contacted using suction type with sites of heat generation, accuracy of data acquisition is high, without power supply
It is reliable to reduce cost, performance safety, and without man-hour manually hand-held sensor close to power supply, avoid maintainer directly with it is powered
The risk that body gets an electric shock when contacting；The real time data monitoring of temperature change state when realizing switch cubicle operation simultaneously, and lead to
Cross the analysis to temperature data and draw switch cubicle running status, draw the overhaul data of standardization, data supporting is provided for maintenance,
Avoid the difference between maintainer so that overhaul data is more accurate, while reduces personal monitoring's cost.
