Abstract

The invention discloses a common enclosed busbar duct. A first enclosed busbar duct and a second enclosed busbar duct form an L-shaped common structure; the first enclosed busbar duct and the second enclosed busbar duct are respectively provided with a first connection shell and a second connection shell; the first enclosed busbar duct and the second enclosed busbar duct are connected with each other through the first connection shell and the second connection shell; the common enclosed busbar duct further comprises a sealed groove; the sealed groove is arranged on the first enclosed busbar duct; and the first connection shell is arranged in the sealed groove, and is used for preventing dust from entering the common enclosed busbar duct. An L section bar and an inverted L section bar are clamped with each other so as to realize connection, the distance between the L section bar and the inverted L section can be adjusted freely, and the common enclosed busbar duct is highly sealed due to clamp of short edges of the L section bars.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a box-common closed bus duct. Background technique [0002] Enclosed busbars (Enclosed busbars or Closed busbars) is a busbar system composed of metal plates (steel plates or aluminum plates) as protective shells, conductive bars, insulating materials and related accessories. Including isolated-phase enclosed busbars, common box (including common-phase and phase-separated) enclosed busbars and cable busbars, they are widely used in power plants, substations, industrial and civil power supply leads. [0003] Common-box closed busbars include non-phase-separated shared-box closed busbars, phase-separated shared-box closed busbars and AC / DC excitation common-box busbars, which are widely used between the lead-out lines of generators below 100MW and the low-voltage side of the main transformer or factory transformers for units of 75MW and above The closed bus bar for curr...
