高压电器外绝缘在线检测技术在电气化铁路的应用研究

Study on Application of Online Inspection Technology for External Insulation of High Voltage Devices of Electrified Railway

为避免电力机车、牵引变电所、接触网发生绝缘子污闪故障,针对高压电器外绝缘在线检测问题,研究高原地区电气化铁路绝缘子泄漏电流与绝缘子污秽关系,制定高原地区高压电器绝缘子泄漏电流检测的具体技术方案,并在电力机车上进行试验,为在牵引变电所和接触网上安装应用获取经验数据。

In order to avoid the pollution flashover faults of insulators on locomotive,traction substation and OCS,with regard to the online inspection of external insulation problems of high voltage electrical devices,the paper studies the relations between the insulator leaking current and insulator pollution for electrified railways in plateau area,establishes detailed technical scheme for leaking current inspection of high voltage electrical devices in plateau area.The test is executed on the locomotive,obtains experience data for installation of devices on the traction substation and OCS.
