列车绝缘检测仪设计

Application for Testing Insulation Based on Train

基于低压配电网绝缘检测的实际需求,研制了一种基于单片机的手持数字式列车绝缘检测仪(数字兆欧表)。介绍了该仪器的硬件部分和软件部分的设计,详述了硬件部分各个模块的功能及软件部分的流程图;并阐述了该仪器的测量网络的选取和测量原理。

Based on the actual needs of low-voltage distribution network insulation, this paper discussed the design of the digital mega-ohm meter for train based on the single chip microprocessor. It introduced the design of hardware and software as well as the function of all modules and flowchart. Meanwhile, it discussed in detail the theory of measuring resistance of train and selection of measuring network.
