接地网置于地下车站结构顶板上方的电气安全性参数研究

Dianci bileiqi
为了研究接地网置于地下车站结构顶板上方时的各项安全性参数，以便总结接地网置于地下车站结构顶板上方这一情况的可行性和适用性条件，在CDEGS软件中建立起了接地网的仿真计算模型。首先对比接地网在车站结构底板下方和结构顶板上方的工频接地电阻值区别，其次展开了车站结构顶板上方的土壤电阻率、结构顶板上方覆土土壤厚度和接地网网格尺寸、导体直径的细化研究。结果表明车站结构顶板上方的土壤电阻率和土壤厚度对接地电阻值起重要作用，接地网的网格尺寸和导体直径对电阻值的影响甚微 ...

动车组车顶电缆层间气隙缺陷对局部电场分布特性的影响

Dianci bileiqi
动车组车顶电缆敷设过程中的弯折可能会在其内部界面间形成微小气隙，畸变其附近局部电场，当动车组列车在运行期间过分相时，其过分相过电压也会进一步提高车顶电缆附近的电场强度，致使车顶电缆及其周围绝缘介质受损，进而使气隙尺寸扩大形成气隙贯穿，严重时将导致电缆被击穿。本文通过电缆弯曲应力公式和梁结构公式确定了气隙易发生的位置。根据电缆实物建立了电缆模型，根据电缆气隙易发位置建立厚度、长度和跨度三种参数变量的电缆内部气隙三维模型。探究了列车正常运行工况下和单次陡波冲击过电压激励下电缆气隙缺陷对其电场强度的影响 ...
