1.概述

过欠压电路课程设计背景

生活中，我们不可避免的要用到要用到各种各样的电气设备。

由于电网电压的波动，在较高的电压下很有可能使电气设备受到损

坏，而在低压时电气设备不能正常工作。那么，在这样的情况下就

需要有一个电压报警指示设备，它可以及时准确地对电网电压进行

分段指示并且对过、欠压进行指示报警，从而实现保护电器设备的

目的。

过欠压电路课程设计目的

1.设计一过/欠电压保护提示电路。

5

2.对给定的电路原理框图进行原理图设计，分单元进行设计。对电

路参数进行必要的计算，选择元器件参数。

3.画出完整的电路原理图。

4.对设计的电路进行仿真验证。要求打印出仿真结果。

设计任务与要求

1.设计一个过欠电压保护电路，当电网交流电压大于250V
