CATENARY'S DECLINATION MEASURING APPARATUS ON PANTOGRAPH

摘要

PURPOSE: An electric wire deflection measuring system of a pantograph is provided to continuously check sudden feeding state of an electric railroad vehicle by monitoring an electric wire is fed at the limited range of a current collector. CONSTITUTION: First and second pressure sensing devices(120, 130) are respectively installed at the left side and the right side of a fan head. The first and second pressure sensing devices measure a pressure value added to the fan head of a pantograph through an electric wire. The pantograph is composed of the fan head and a base frame. A data transfer device(160) is input the pressure value detected through first and second pressure sensing devices. A computer(170) computes a deflection value by using the pressure value of the first and second pressure sensing devices inputted in the data transfer device.
