Abstract

See full text

The invention provides an AC/DC conversion device for intelligent green-power operation and maintenance in power transmission and transformation projects, including a cabinet, an assembling panel, an inverter, a driving mechanism and a controller. A door is mounted at the front portion of the cabinet in a fixed and sealed manner, and the assembling panel is fixedly mounted on the back wall of the cabinet inside the cabinet. The assembling panel, the inverter, the driving mechanism and the controller are all provided inside the cabinet, which provides desirable dust-proof effects, preventing the case where the inverter, the driving mechanism and the controller are interfered by the dust, so that this device is suitable for outdoor usage. The driving mechanism and the controller work in coordination, so that the inverter can be switched off in time when it burns out and smokes, thereby substantially reducing the risk of fire hazards.
