毕业设计(论文) 题目电气设计中低压交流接触器的选用所属系部机电工程系所学专业机电一体化班级学生姓名指导教师职称 20 15年5月电气设计中低压交流接触器的选用 1 电气设计中低压交流接触器的选用摘要: 低压交流接触器主要用于通断电气设备电源, 可以远距离控制动力设备, 在接通、断开设备电源时避免人身伤害。交流接触器的选用对动力设备和电力线路的正常运行非常重要, 本文提出了电气设计过程中选用低压交流接触器时需要考虑的主要因素, 低压交流接触器的结构与参数, 低压交流接触器的选择原则, 并介绍了不同负载下交流接触器的选择原则。关键词: 交流接触器;低压; 电气设计;安装 Selection of low voltage AC contactor in electric design Abstract: the low voltage AC contactor is mainly used in the power supply of the power supply of the power equipment, which can be used to control the power equipment. The selection of AC contactor of power equipment and power transmission lines in normal operation is very important. In this paper, the use of low-voltage AC contactor in the process of electrical design need to consider the main factors, structure and parameters of low-voltage AC contactor, the choice of low-voltage AC contactor principle, and introduces the different load and the selection principle of AC contactor. Key words: AC contactor; low voltage; electrical design; installation 电气设计中低压交流接触器的选用 2 目录前言............................................................................................................................................ 3 第一章交流接触器的概述....................................................................................................... 4 交流接触器的基本组成............................................................................................... 4 交流接触器的工作原理.............................................................................................. 4 交流接触器的使用接法............................................................................................... 4 交流接触器的型号划分............................................................................................... 4 交流接触器的基本分类............................................................................................... 5 电磁式折叠........................................................................................................ 5 永磁式折叠.........................
