MOVABLE CATENARY SYSTEM FOR DC ELECTRIC RAILWAY

摘要

The present invention relates to a movable catenary system for a DC electric railway. An objective of the present invention is to provide a movable catenary system of a DC electric railway capable of improving space utilization and minimizing space limitation by preventing a DC current from being leaked and reducing an insulation spacing distance while maintaining insulation strength. The movable catenary system of a DC electric railway includes a DC movable catenary (10) connected to at least one DC motor bracket (100) and at least one hinge bracket (200) to be connected and separated to and from a fixed catenary by the operation of the DC motor bracket; a DC power disconnector (20) to open and shut an electric circuit for supplying or blocking a DC current to or from the movable catenary or the fixed catenary; a crane (30) to move a heavy object on a vehicle; a working stand (40) installed at a side of vehicle entering a train inspection station in order for a worker to ascend and descend; a controller (50) to control the opened and shut states of an electric circuit of the disconnector, the operation of the crane, and the opened and shut states of a door on the working stand; and a DC voltage detecting sensor (contact type or non-contact type) (60) to exactly and stably light a supply display of supply/block display unit (61) by detecting DC voltage supplied from the disconnector.
