  • Low aerodynamic noise type current collection equipment
    Patent number: 5566799
    Abstract: Low aerodynamic noise type current collection equipment is provided for reducing variations in aerodynamic force applied to a current collector during train operation. A central region (2a) of a current collector (1) having a collector head (2) with a top surface in which a contact strip (3) is embedded is rectangular in cross-section, and each side region is shaped convex in cross-section in the front and rear directions, with e.g. an elliptical shape. The rectangular shape has characteristics such that the magnitude of the aerodynamic lift force would be kept substantially constant even if the inclination angle against the aerial flow would be changed.
