变电站直流系统绝缘监察仿真装置的设计

针对电力系统实验不能在现场模拟操作而使学生能更好的了解电力系统的现象,研究设计了一种变电站直流系统绝缘监察仿真装置.该装置能模拟直流系统金属性和非金属性接地,利用警铃和光字牌的声、光效果来模拟直流接地时绝缘监察装置发出的音响信号和灯光信号,及早发现绝缘降低并处理.该装置能完成电气类学生的专业课实验,填补了本专业在直流接地方面教学中的空白,实现了学生能在课堂上操作模拟现场现象,将教学和现场实践有机结合,到达较好的教学效果.

Design of DC System Insulation Monitoring Simulation Device for Transformer Substations

Since the power system experiments can not be simulated in the field,however,enabling students to better understand the phenomenon of the power system,a DC system insulation monitoring simulation device was designed.The device can simulate metallic and non-metallic grounding,make use of alarm and light plates sound and light effects to simulate audio signals and light signals that the insulation monitoring device issues when DC grounding,therefore,it can complete the experiments required for major electrical students,fill the blank of the professional teaching in DC grounding,and then realize the students ’ operation in the classroom to operate the simulated scene,combining teaching and field practice,finally reaching a better teaching effect.
