三相自复式过欠压保护器设计

Design of Three-Phase Self-Reset Overvoltage or Undervoltage Protector

介绍了三相自复式过欠压保护器的工作原理,给出了原理框图及电路原理图。设计的三相自复式过欠压保护器能实现过欠压保护功能和过欠压状态指示功能,保证了供电质量,满足设计要求。

This paper introduced the working principle of three-phase self-reset overvoltage or undervohage protector. The principle block diagram and circuit schematics were given. The three-phase self-reset overvohage or undervoltage protector realizes ovcrvoltage or undervohage protection function and display function, ensuring the quality of power supply, which meets the repuirements of design.
