The present apparatus is to guarantee the reliability of weak electricity system work, and cable voltage class 10Kv, temperature probe power supply uses lithium
Battery, the communication with data collection station use wireless data transmission, guarantee the electrical isolation of temperature probe and weak electricity system, peace
Dress mode is to be fixed on end；
Battery powered greatest problem is cruising ability, it is contemplated that the battery of larger capacity is not available, so thermometric
It pops one's head in and selects the single-chip microcontroller of low-power consumption series when design to carry out temperature acquisition, and passed with the data of data collection station
The defeated LoRa Radio Transmission Technology for also selecting low-power consumption, ensure that the cruising ability of battery；
Data collection station can also transfer data to confession while receiving temperature probe collected temperature data
The control room of electric office or related maintenance personnel debug in time if temperature anomaly phenomenon occurs, avoid serious consequence；
The present apparatus uses wireless communication transmissions, and measurement accuracy is high, transmission loss is low, protective characteristic is good, can be realized thermometric
The electrical isolation of probe and weak electricity system.
