摘　　要：为避免常用电器在超温、超湿的环境中使用,提出了一种性能可靠的常用电器保护电路方案:一是对电器内部的温度、湿度进行实时监控;二是当电器内部出现超温、超湿时,要求能立即自动切断供电电源,并同时启动报警器,使电器得到有效保护.这种常用电路保护装置是由温度检测处理、湿度检测处理、报警电路、供电电路控制四部分组成.This paper is to,in order to avoid common appliances being used in over-temperature and over-humid environment,put forward a reliable performance of the commonly used electrical protection circuit scheme： one is the real-time monitoring on inner temperature and humidity;another is the effective protection of the appliances by automatic power cutoffand alarming while the over-temperature or over-humid occurs.The commonly used circuit protection device is handled consists of four parts： temperature testing,humidity testing,alarm circuit,and power supply circuit control.

关 键 词：超温 超湿 报警 切断电源
