轨道交通电连接器国内环境试验标准分析

铁路作为国民经济大动脉、国家重要基础设施和大众化交通工具,在国民经济和社会生活中的作用至关重要。电连接器是铁路车辆设备的关键器件之一,有着很高的安全性和可靠性要求。着重分析了轨道交通电连接器标准中的电性能、机械性能和环境适应性的试验方法,并对这些标准进行了对比总结。经分析发现,更新版本的标准比被替换的标准增加了试验项目,细化了试验条件。然而,目前国内轨道交通电连接器的标准版本相对落后,仅GB/T 25022和GB/T 25023为2010年发布实施。亟需新的标准或试验方法以指导轨道交通电连接器的质量检测和认证。

Analysis on Domestic Environmental Test Standard for Electric Connector of Rail Transit

As a public traffic media, railway is extremely important for social and economy. Electric connector requires high safety and reliability, as a key component of rail products. This paper analyzes and compares rail electric connector’s standards involved electrical property, electrical property and environment tests. It is found that the newer standards adds test items and detail test conditions. However, the standards are relative backward, only GB/T 25022 and GB/T 25023 published in 2010. In order to guide the quality inspection and certificate of railway’s electric connector, it is desiderated new standards and test methods.
