Analysis and Simulation of Grounding Modes for Shielded Cable in Electric Locomotive

机车上电力电子设备是系统主要干扰源之一,设计中常采用屏蔽电缆来防护干扰。本文针对常见机车干扰提出屏蔽层所需采用的最佳接地方式,阐述其干扰防护的基本原理并进行仿真验证,对工程实际中电缆接地方式的选择有重要参考价值。

Power electronic equipment is one of the main interference sources in electric locomotive, so the shielded cables are generally taken to control interferences. It presented the best grounding modes of shielded cable aiming at the common electric locomotive interferences, described the interference protection principle and simulated the grounding methods, which has important references for the selection of the cable grounding modes in engineering practice.
