在地铁屏蔽门的直流供电系统的基础上,提出TN-S接地方式,门体与钢轨保持等电、与站台结构绝缘等保护措施,提出供电系统的电磁兼容性能验收项目、参考标准、试验规格、试验部位、极限值,提出屏蔽门门体顶部及底部的绝缘电阻、绝缘强度.验收试验可供检测国产化地铁设备作参考.
On the basis of the DC power supply system of subway screen door, this paper puts forward the protection measures of TN-S grounding mode, door body and rail to keep the same electricity, and the platform structure insulation and so on, and puts forward the project of electromagnetic compatibility of power supply system acceptance, reference standard, test specification , The test site, the limit value, put forward the insulation resistance and insulation strength of the top and bottom of the screen door.The acceptance test can be used as a reference for testing the domestic subway equipment.
