|
摘要
电力机车网侧高压设备高度集成安装的网侧柜越来越多在电力机车上使用。本文根据某一和谐型机车网侧柜,抽离出关键内部电气设备部件并作出合理简化模型,基于COMSOL Multiphysics多物理场有限元仿真软件进行该网侧柜进行稳态运行及典型过电压下的电场仿真分析。依据仿真结果,分析了车载网侧柜电气设备关键部件布置中存在绝缘问题,并提出优化意见。
The highly integrated high voltage equipment locomotive switchgear cabinet,are integrated on the network side of the electric locomotive,which was more and more installed in the electric locomotive. According to a certain type of harmony-type locomotive switchgear cabinet,extracted the electrical equipment key parts and make a reasonable simplified model. Based on the COMSOL Multiphysics multi physical field finite element simulation software,simulated and analysised the electric field under steady state operation and operation over-voltage. According to the simulation results,analyzed the insulation problem in the layout of the key components of the electrical equipment in the ocomotive switchgear cabinet,and the optimization suggestions are put forward.
