关于车辆高压电缆终端伞裙污闪问题及纳米材料应用的分析

Analysis of Problem of Pollution Flashover on Umbrella Skirt of High-voltage Cable Terminals In Vehicles and Application of Nanomaterials

电力动车组(下文简称动车组)受流模式均为架线取电,车顶高压设备将电力传输至动力单元驱动车辆,高压电缆在传输电力过程中,因外接环境等复杂因素容易产生污闪放电,本文从产品机理、污闪条件、纳米材料在产品的应用及试验验证等几个方面进行研究,提供针对污闪放电问题的分析思路和新型材料应用的可行性说明。

The current collection mode of electric multiple units(EMUs)is all overhead power supply,and the high-voltage equipment on the roof transmits electricity to the power unit to drive the vehicle.During the power transmission process,high-voltage cables are prone to pollution flashover discharge due to complex factors such as external environment.This article studies the product mechanism,pollution flashover conditions,application of nanomaterials in products,and experimental verification from several aspects,Provide analysis ideas for pollution flashover discharge problems and feasibility explanations for the application of new materials.
