摘　　要：通过对比纯电动和无轨电车的电源安全机制以及整车高压部件的混合绝缘和附加绝缘安装方式的触电风险,论证除隔离型DC/DC外,双源无轨电车其他高压部件若采用基本绝缘安装方式,人员触电的风险更低。By comparing the electric power safety mechanism of pure electric vehicles and dual-source trolley buses and the electric shock risk of the mixed insulation installation and the additional insulation installation for the high-voltage parts of the vehicle,the author demonstrates that the risk of electric shock for persons is lower if other high-voltage parts of a dual-source trolley bus adopt the basic insulation installation except the isolated type DC/DC.

关 键 词：双源无轨电车 电安全性 附加绝缘 基本绝缘
