三、因保护电路及检测电路本身出故障而“误保护”保护电路动作原因可分为两种类型:一种是因被保护电路出现故障而保护电路执行正常的保护动作(俗称“正常保护”);而另一种则是因保护电路及检测电路本身出现故障而误动作(俗称“误保护”)。本节例子则指后一种,即“误保护”自动关机。
Third, due to the protection circuit and the detection circuit itself fails and “wrong protection” protection circuit action can be divided into two types: one is due to the protection of the circuit failure and protection circuit to perform normal protection (commonly known as “ Normal protection ”), while the other is malfunctioning due to the failure of the protection circuit and the detection circuit itself (commonly known as“ false protection ”). The examples in this section refers to the latter, that is, “wrong protection” automatically shut down.
