摘要
研究了过流电流截止型保护电路的设计思想、元器件的选择方法以及在此基础上限流值的扩展；讨论电路自动恢复，给出了自动恢复的条件．
The paper expounds the design philosophy of the current cut off protection circuit (Fig1),introduces the selection methods of the components,expands the upper current bound,and discusses the problem of automatic recovery of the circuit.So the guideline of automatic recovery rejects the incorrect explanations,the conclusions are verified by experiment.
