基于接触式测温系统检测电流分析

Current Detection Based on Contact Temperature Measurement System

传统的电流检测方法存在中断电路、功耗损失、精度受限、难以适应大电流和受温度影响等缺点。为了克服这些问题,文章提出了利用温度来间接检测电流的方法,这种检测方法可以准确检测大电流,同时导体的散热也可以计算在内来减小误差。

The traditional current detection method has some disadvantages such as interrupt circuit,loss of power consumption,limited accuracy,difficult to adapt to high current and temperature.In order to overcome these problems,an indirect current detection method using temperature is proposed.This detection method can accurately detect large current,and the heat dissipation of conductors can also be calculated to reduce the error.
