GB/T 21561.2-2008 in English

《GB/T 21561.2-2008轨道交通 机车车辆 受电弓特性和试验 第2部分：地铁与轻轨车辆受电弓》由TC278（全国轨道交通电气设备与系统标准化技术委员会）归口，TC278SC1（全国轨道交通电气设备与系统标准化技术委员会机车车辆电气分会）执行，主管部门为国家铁路局。
ＧＢ／Ｔ２１５６１《轨道交通　机车车辆受电弓特性和试验》分为两部分，本部分为ＧＢ／Ｔ２１５６１的第２部分。为保证能从接触网系统中集取电流，本部分规定了应用于地铁与轻轨车辆受电弓的通用特性。本部分也规定了受电弓(不包括绝缘子在内)应进行的试验。本部分不适用于受电弓的介电试验，该试验应对安装在车顶上的受电弓进行。这些规定也可适用于有轨电车。本部分等同采用ＩＥＣ６０４９４-２：２００２《轨道交通　机车车辆　受电弓特性和试验　第２部分：地铁和轻轨车辆受电弓》（英文版）。

Scope

In order to ensure that the current can be collected from the catenary system, this part specifies the performance characteristics of pantographs applied to subway and light rail vehicles. This standard also specifies the tests to be performed on pantographs (excluding insulators). This section does not apply to the dielectric test of the pantograph, which shall be carried out on the pantograph mounted on the roof of the vehicle. These regulations may also apply to trams. This part does not apply to the pantographs of main-line rolling stock, see GB/T 21561.1 for pantographs of main-line rolling stock. This section is concerned with conventional suspended catenary systems and auxiliary equipment. For rigidly suspended systems (or parts thereof), special considerations are required between the user and the supplier.
