High speed low noise current collecting equipment

摘要

To provide a low noise current collector 20 which has excellent controllability and response, and is suitable for high speed railway vehicles, the functions of the trolley wire 1 and the conducting of current for collected electric power are separated. The current collector 20 comprises a current collecting member 21, a driving cylinder 32 to move said current collecting member, a supporting insulator 30 for insulation, a cable head 50 for current conduction to support a conductor covered with insulator juxtaposed with said driving system and directing the current to the load side. The whole body of the current collector 20 is lowered with a cylinder for raising and lowered 7 to be contained in a containing dome 4 when it is not in use.
