CN203496906U 一种电力机车顶部绝缘材料顶盖 有权

一种电力机车顶部绝缘材料顶盖
摘要：
本实用新型公开了一种电力机车顶部绝缘材料顶盖，它包括设置在安装受电弓区域及其周围的绝缘材料复合层，受电弓安装座镶嵌于绝缘材料层中；所述绝缘材料复合层周边镶嵌有垫片；所述绝缘材料复合层耐雷电冲击试验电压U1=243±10kV、工频耐压试验的试验电压U2=94±5kV；所述绝缘材料复合层包括真空整体成型的绝缘材料复合层上层和绝缘材料复合层下层。本实用新型外形美观，整体协调性好，与电力机车顶部金属顶盖接触面导电性能好。固定在电力机车顶部金属顶盖上，使受电弓通电时，消除绝缘顶盖下方的静电或电晕。
摘要（英）：

The utility model discloses an insulation material top cover on the top of an electric locomotive. The insulation material top cover comprises an insulation material composite layer arranged in and around an installation pantograph area, a pantograph installation base is embedded into the insulation material composite layer, spacers are embedded into the periphery of the insulation material composite layer, the lightning-impulse-resisting testing voltage of the insulation material composite layer is U1 which is 243+/-10kV, the testing voltage of a power-frequency voltage-withstand test is U2 which is 94+/-5kV, and the insulation material composite layer comprises an upper insulation material composite layer and a lower insulation material composite layer both of which are integrally formed in a vacuum mode. The insulation material top cover is attractive in appearance and good in integral coordination performance and conductivity performance with the contact face of a metal top cover on the top of the electric locomotive. The insulation material top cover is fixed on the metal top cover on the top of the electric locomotive, and static electricity or corona below the insulation top cover is eliminated when a pantograph is powered on.
