The invention discloses a power supply and grounding integrated device applied to a contact line. The device comprises: a shell provided with an accommodation cavity, and a three-station isolation switch arranged in the accommodation cavity and provided with a power supply contact, a grounding contact and a knife switch contact, wherein the power supply contact is electrically connected with an external power supply cable, the grounding contact is electrically connected with an external grounding cable, and the knife switch contact is electrically connected with an external contact line. According to the invention, when the knife switch contact is biased to abut against the power supply contact, the power supply cable supplies power to the contact line, and when the knife switch contact isbiased to abut against the grounding contact, the charges of the contact line are led out to the ground, so that maintainers are protected during detection and maintenance, the functions of power supply and grounding maintenance are integrated, the space occupied by equipment is reduced, and the cost is reduced; and the knife switch contact can only be biased to the power supply contact or the grounding contact, so that the uniqueness of the power supply state and the grounding state can be guaranteed without electrical linkage, and the reliability is high.

    本发明公开了一种应用于接触网的供电接地一体化装置,包括:壳体,设置有容腔;三工位隔离开关,设置在所述容腔内,所述三工位隔离开关设置有供电触头、接地触头以及刀闸触头,所述供电触头与外部供电线缆电性连接,所述接地触头与外部接地线缆电性连接,所述刀闸触头与外部接触网电性连接。刀闸触头偏置与供电触头抵接时,实现供电线缆向接触网供电;刀闸触头偏置与接地触头抵接时,将接触网的电荷导出至地,保护检修人员进行检测维护。以此,实现将供电、接地检修功能集成于一体,减少设备占用空间并且降低成本,同时刀闸触头只能偏置到供电触头或接地触头,无需电气联动即可保证供电状态和接地状态的唯一性,可靠性强。
