标准摘要
[中文适用范围]： 本文件适用于直流牵引系统中应用的限压装置 (VLD)，以符合 IEC 62128 系列@ 的防触电保护规定，并考虑杂散。现行规定。 VLD 的工作方式是将直流铁路系统的轨道回路连接到接地系统或架空接触线区域或集电器区域内的导电部件。 [外文原描述]： IEC 62848-2:2019 applies to Voltage Limiting Devices (VLDs) to be applied in DC traction systems in order to comply with protective provisions against electric shock from DC, and combined AC – DC voltages, in accordance with the IEC 62128 series, taking into account stray current provisions. VLDs operate in such a way as to connect the track return circuit of DC railway systems to the earthing system or to conductive parts within the overhead contact line zone or current collector zone.
