摘　　要：从站台门与钢轨等电位联结的关系图入手,系统分析了其绝缘安装应满足钢轨回流和限制电流通过人体的电流的基本要求,明确了站台门绝缘安装电阻值确定的原则与方法。现行相关标准确定的绝缘安装电阻值宜作为建设期的验收标准。从满足系统运行安全和人身安全的角度,提出了站台门绝缘安装运营期间的维护标准。Basic requirements that the insulating installation of platform gates shall satisfy the rail return current and limit the current passing the human body are systematically analyzed according to the interrelationship diagram of equipotential bonding between the platform gate and the rail, to define the principle and method for determining the resistance for insulating installation of the platform gate. The resistance for insulating installation specified by existing relevant standards is suitable to he used as an acceptance standard maintenance standard for operation period of the for construction period. A insulating installation and platform gate is presented from the perspective of satisfying operation safety and human safety.
