一种电源电压保护结构
摘要：
本发明涉及一种电源电压保护结构，其特征在于，包括依次连接的整流单元、监测单元、稳压基准单元、比较单元和保护单元。本发明的电源电压保护结构既能够适用于工业，也可以适用于民用的用电设备，其能够在过压欠压发生的时刻可靠的切断电源保护后续用电设备，从而保证了工业或民用供电恶劣环境下电设备的安全运行。
摘要（英）：

The invention relates to a supply voltage protection structure. The structure is characterized by comprising a rectifying unit, a monitoring unit, a voltage-stabilizing reference unit, a comparison unit and a protection unit, all of which are sequentially connected. The supply voltage protection structure can be suitable for both industrial and civil electrical equipment and can reliably cut off power to protect the subsequent electrical equipment at a moment when overvoltage or undervoltage occurs, and therefore safe running of the electrical equipment in a severe environment of industrial orcivil power supply is guaranteed.
