摘 要

电工实训教学是一门重要的实践课程，多年来在培养学生动手能力、工程实践能力及创新能力等方面发挥了重要的作用。本文介绍了桂林电子科技大学信息科技学院电工实训教学的现状，着重分析继电器控制线路及其元件的工作原理，电工技术知识及掌握电子线路的基本原理、基本方法，通过具体的电路图，初步掌握简单电路元件装配。培养学生理论联系实际的能力，提高分析问题和解决问题的能力，增强独立工作能力，培养学生团结合作，共同探讨，共同前进。

关键词：电工实训；电工技术；电路元器件

电工实训教学是理工科院校的一个重要实践性教学环节，实训的主要目的是将学到的专业知识再带回实际中，通过再认识的方法，将感性的和理性的专业知识融合起来，进行深层次的专业强化。目前，在高等院校实践教学环节中，较少涉及专业知识的工程应用，与工程训练存在着或多或少的差距。目前，高校学生就业压力越来越大，因此，有必要改变传统教学模式，对学生的实用技能培训，即在实践教学中，形成系统的专业训练体系并不断融入新的知识和技能的训练，是学生素质与社会需要相接轨，在就业竞争中增加优势。近年来，在高等院校加强实践教学改革的大环境下，桂林电子科技大学信息科技学院电工实训教学也不断改变设施设备陈旧、技术落后的局面，在教学中引入了许多新型电气装置，如变频器、气动装置、信号通信仪等。使学生对电气元件及电工技术有一定的感性与理性的认识，对电工技术等方面的专业知识做进一步的理解。同时，通过实训使学生掌握低压电气元件的使用、拆装、认知，电工操作基本知识，使电安全基本知识，电机控制电路的设计；培养学生理论联系实际的能力，提高分析问题和解决问题的能力，增强独立工作能力，培养学生团结合作，共同探讨，共同前进精神。

Abstract

Electrician Training is an important teaching practical courses over the years in students ability, engineering practice and innovation has played an important role. This article describes the Guilin University of Electronic Science and Technology College of Electrical Information Technology Training status of teaching, focusing on analysis of relay control circuit and its components works, electrical and technical knowledge to master the basic principles of electronic circuits, the basic approach, through specific circuit, the initial master the simple circuit component assembly. Students the ability

to integrate theory with practice to improve the analysis of issues and problem-solving skills, enhance the ability to work independently, unity and cooperation among students, to explore, and common progress.

Key words：Electrician training; Electrotechnical; circuit components

Electrician Training Teaching is an important practical engineering colleges teaching, the main purpose of training is to learn professional knowledge and then back to practice, through further understanding of the way, the emotional and rational integration expertise up, for in-depth professional enhancement. Currently, colleges and universities practice teaching, the less involved the application of engineering expertise, and there are more or less engineering training gap. Currently, the employment pressure on college students and thus the greater the need to change the traditional mode of teaching, the students practical skills training, that is, in practice, teaching, form a system of professional training system and the continuing integration of new knowledge and skills training , is the quality of students and social needs of convergence, increased competition in the employment advantage. In recent years, the practice of teaching in higher education institutions to strengthen the reform of the environment, Guilin University of Electronic Science and Technology College of Electrical Training Teaching Information Technology is also changing facilities, outdated equipment and technical backwardness, introduced in the teaching of many new electrical devices, such as inverter, pneumatic devices, signal communication apparatus. So that students of electrical components and electrical technology has some emotional and rational understanding of the electrical technology expertise for further understanding. At the same time, through training to enable students to master the use of low-voltage electrical components, disassembly, cognitive, basic knowledge of electrical operation, the basic knowledge of electrical safety, motor control circuit design; students the ability to integrate theory with practice to improve the analysis of problems and solutions problems, enhance ability to work independently, students unite together to explore common spiritual progress.
