摘要
提出一种采用功率检测方式实现的过电流与过功率保护器,分析了功率检测器的基本工作原理,以MAX4211为核心,设计了过电流与过功率保护器,给出了测量误差曲线。该方法优于传统的电流检测方式的电路断路器,具有重要的工程实际应用价值。
The method and benefits of using a power-sensing approach rather than a current-sensing approach to implement a circuit breaker are shown.The basic principle of power-sensing current protector is analyzed,the power-sensing current protector based on MAX4211 is designed,and its error curves is showed. It is better than tradition current breaker,and its vital value in engineering application is shown.
