继电器在电气工程及其自动化低压电器中的应用研究

Research on application of relay in electrical engineering and its automatic low-voltage apparatus

随着我国物理科学技术的发展,各种电器设备已经应用到我们的日常生活中。电从发明至今给人们的生活带来了巨大的改变,人类在利用电给我们生活带来便利的同时,还应做好用电保护工作。继电器就是为了保护电路而产生的,继电器在电气工程及其自动化的电路输出中起到保护电路、控制电路和电路转换等作用。通过介绍继电器的工作原理、类型等方面的内容,研究继电器在电气工程及其自动化低压电器中的应用,以寻求继电器更好的发展。

With the development of physical science and technology in China,a variety of electrical equipment has been applied to our daily life. Electricity has brought great changes to people＇s lives from its invention,therefore,we should also do a good job of electricity protection. Relay is born for protecting the circuit,which plays the role of protecting circuit,control circuit and circuit switching in electrical engineering and its automatic circuit output. Through the introduction of working principle,type and other aspects of the relay,the application of the relay in electrical engineering and automatic low-voltage apparatus was researched in this paper,so as to seek better development of the relay.
