The invention discloses a connection structure of a vertical bus of a rectifier cabinet, and relates to the rectifier cabinet field. the connection structure includes a rectifier cabinet, a lower bearing plate is arranged on the front side wall of the rectifier cabinet; a first rubber pad is arranged at the top of the lower bearing plate; a lower direct-current bus copper bar is arranged at the top of the first rubber pad; the rear side of the lower DC bus copper bar is provided with a DC confluence water-cooling copper bar. A copper bar fixing plate is arranged on the lower direct-current buscopper bar, a fixing arc-shaped plate is arranged on the copper bar fixing plate, a copper bar partition plate is arranged at the top end of the lower direct-current bus copper bar, a connecting wireis arranged at the top of the copper bar partition plate, an upper bearing plate is arranged at the top of the connecting wire, and an insulating plate is arranged at the top of the upper bearing plate. The weight of the lower direct-current bus copper bar pressed on the direct-current confluence water-cooling copper bar is reduced, the acting force of the lower direct-current bus copper bar on the direct-current confluence water-cooling copper bar is greatly reduced, and deformation of the direct-current confluence water-cooling copper bar is avoided.
Description
technical field [0001] The invention relates to the field of rectifier cabinets, and more specifically, the invention relates to a connection structure of a vertical bus bar of a rectifier cabinet. Background technique [0002] In many places, the outlet structure of the rectifier cabinet is suitable for the vertical outlet structure; that is, the bus bar of the rectifier cabinet itself is perpendicular to the copper bar of the DC bus that needs to be drawn out. The DC confluence water-cooled copper bars of the rectifier cabinet are generally water-cooled busbars, while the copper busbars connected to the vertical outgoing lines are self-cooled, and the carrying capacity of the self-cooling type is much smaller than that of the water-cooled type, so The copper bus bar of the rectifier cabinet is much thicker than the cross-section of the DC confluence water-cooled copper bar, so the DC confluence water-cooled copper bar is very heavy. If the weight of the copper bus bar is ...
