基于热效应的电流改装装置

现阶段家庭电路保险装置大多数为空气开关和保险丝两种。目前这两种装置都是在电路过载之后进行切断保护。之后,人们自行连接时存在一定的危险性。文章的实验装置是在家庭使用电流没有达到额定电流之前,即将达到额定电流时进行报警,使人们在电路被烧坏之前采取措施,有效避免电路被烧坏,从而使人们不用自行安装保险丝或者空气开关,提高了家庭电路的安全性,可让人们更方便、更快捷、更安全地用电。

At present,most of the household circuit safety devices are air switches and fuses.At present,these two kinds of devices are protected by cutting off after the circuit is overloaded.After that,it is dangerous for people to connect them.The experimental device of this paper is to give an alarm when the household current is not up to the rated current and is about to reach the rated current,which causes people to take action before the circuit is burnt out.This method has effectively prevented the circuit from being burned out,so that people do not have to install fuses or air switches themselves.Plus,the security of household circuit is improved,so that people can use electricity more conveniently,quickly and safely.
