一种基于自具电源的智能无线电流温度传感器

A Smart Wireless Current Temperature Sensor Based on Its Own Power Supply

电流互感器在电力行业中被广泛应用于电流的测量,也有部分场合用来给监测装置供电,但很少电流互感器既用来测量电流值,又当作电源来使用。基于自具电源的智能无线温度传感器采用开合式结构设计,首次将电流互感器既当作电源用,又用来测量线路的电流值。此外传感器还带有无线通信、测温、带电指示、故障指示和故障录波等功能。

The current transformer, widely used for current measurement in the power industry, is sometimes used to supply power to monitoring devices. However, it is seldom used for current measurement and power supply at the same time. As the smart wireless temperature sensor with its own power supply adopts retractable structure in its design, for the first time we use the current transformer for both power supply and line current measurement. Furthermore, the sensor has such functions as wireless communication, temperature measurement, electric indication, failure indication and fault recording.
