Description

technical field [0001] The invention relates to an on-line monitoring element of electric equipment parameters, in particular to a passive wireless temperature and current sensor. Background technique [0002] The wireless temperature sensor is usually composed of four parts: lithium battery, micro control unit, temperature sensor, and wireless module, and works in an all-digital mode. It is installed on high-voltage equipment and equipotentially measures equipment temperature. The wireless temperature measurement sensor transmits the temperature signal to the wireless aggregation terminal wirelessly. The wireless aggregation terminal can receive the data of multiple wireless sensors and forward all the temperature data to the computer temperature early warning system through wired communication. Commonly used wireless temperature measurement sensors are as follows: 1. Traditional wireless temperature measurement sensors; 2. Wireless temperature measurement sensors powered ...
