SWITCHBOARD DOOR LOCK

摘要

PURPOSE: A door lock for a distribution board is provided to automatically lock or unlock a handle of a door of a distribution board, thereby reducing an electric shock of an inspector. CONSTITUTION: A power unit supplies power. A controller receives power supplied from the power unit to control various components by a preset program. A call button(114) sends a call signal for unlocking a handle of a door of a distribution board by the controller. A state display unit(120) is electrically connected to the controller. The state display unit displays whether the handle of the door is locked or unlocked by the controller. A receiving unit(106) inserts a handle of the door of the distribution board into an insertion groove(104).
