The present invention relates to a retractable catenary system for electric railway depots, and more specifically, to a retractable catenary system for electric railway depots, which is capable of moving a catenary to obtain a work space for workers and prevent a safety accident such as an electrical shock during inspection and maintenance of an electric railway vehicle, wherein the catenary is arranged to be vertically moved, and thus which is not under space constraints of the electric railway depots, has a simple structure, and prevents warping or distortion of retractable catenaries. The retractable catenary system for electric railway depots includes: a fixed catenary (110) which has a specific length with one end connected to a conducting wire and is constructed in an electric railway depot by a post; a retractable catenary (120) which is aligned with the fixed catenary in the electric railway depot and electrically connected to the fixed catenary to supply current to a vehicle; a depot structure (130) which is installed at a ceiling part of the electric railway depot; a vertically-flexible means (140) which is vertically flexible and includes a fixing bracket for fixing the retractable catenary with a top end part fixed at the depot structure and a bottom end part connected by an insulator; and a lifter (150) which is connected to the vertically-flexible means to lengthen or shorten the vertically-flexible means so that the retractable catenary can be vertically moved.
