Abstract
The invention discloses a movable overhauling power supply system special for a direct-current screen, which consists of four modules, namely a rectification module, a feeder line module, a detection module and a multi-way ceaseless change-over switch module; the input of the rectification module is connected with three-phase alternating-current electric supply to generate control bus and closing bus direct-current power supplies. The feeder line module comprises three groups of insertion terminals: 1. access ends of control bus and closing bus direct-current power supplies generated by the rectification module; 2. access ends of control bus and closing bus direct-current power supplies of an overhauled direct-current screen; and 3. connection ports of multi-way feeder lines. The detection module is used for: 1. detecting the input and output of the rectification module; and 2. detecting the voltage/current of each feeder line loop. The width of the moving contact of a multi-way ceaseless change-over switch (a transition exchange switch) is greater than the space between two-way static contacts. The movable overhauling power supply system provided by the invention has the advantages that uninterrupted power pulling back can be realized; the system is convenient to move, and error operation generated by wiring can be avoided; and the operation mode is safe, simple and rapid, and the overhauling efficiency is improved.
