A resistance room of the railway car war electricity converter has a resistance short-circuit prevention function

摘要

The present invention relates to a resistance room of a power conversion device for a railway vehicle, and particularly includes a variable panel that opens and closes the resistance room air flow holes by sliding the ceiling and the bottom of the resistance room, so that snow or rain flows during rainfall or snowfall. By preventing this, it relates to a resistance room of a railway vehicle power converter having a resistance short-circuit preventing function to prevent a short circuit of a resistor installed in the resistance room and a secondary accident caused by the same. In the resistance room of the power conversion device for a railway vehicle, the resistance room is provided, the resistance room is formed in the ceiling and floor resistance room air through hole for cooling the resistance; On the ceiling and the floor of the resistance room, the resistance room air distribution hole is closed to prevent the inflow of snow or rain through the resistance room air distribution hole during snowfall or rainfall, and the resistance room air distribution hole is normally opened. It characterized in that it comprises a; a variable panel is formed to be movable to.
