电缆波过程教学实验设计

Design on Teaching Experiment of Cable Wave Process

电缆波过程是高电压技术教学中的重要内容,其教学难点在于晦涩难懂的理论公式和较为抽象的概念。因此为满足电力系统人才培养及教学计划需要,使学生熟练掌握电缆波过程的相关理论,以固定幅值和频率的方波发生器作为信号源,以两根150 m长电缆作为实验研究对象,结合有限元仿真计算相关特性参数搭建电缆波过程教学实验平台。该实验平台能够基本体现电缆波过程的整体发展过程,对开展理论教学有一定的借鉴意义。

Cable wave process is an important part of high-voltage technology teaching. The key and difficulty of teaching lie in obscure theoretical formulas and abstract concepts. In order to meet the needs of power system personnel training and teaching plan, and make students master the theory of cablewave process, the corresponding experimental research is carried out. In this work, the square wave generator with fixed amplitude and frequency is used as the signal source, and two 150 m long cables are applied to the experimental research object. and the relevant characteristic parameters of finite element simulation are used to build the cable wave process teaching experimental platform. The experimental platform can basically reflect the overall development process of the cable wave process, which has certain reference significance for carrying out theoretical teaching.
