This utility model provides a common-enclosed
busbar with a dehumidification structure, relating to the field of
power transmission line technology. It includes an outer casing with multiple busbars equidistantly installed inside. A dehumidification
assembly is installed on the top of the casing, comprising an air inlet box. The air inlet box is fixed to the outer wall of the top of the casing, and a
drying box is fixed to the inner wall of the top of the casing. A
drying layer is fixed inside the
drying box, and pulleys are rotatably mounted at both ends of the drying layer via bearings. Compared to existing technologies, the movement of the
transmission belt drives two sets of horizontal tubes to move around the inside of the casing, and the baffle guides the incoming air, drying it from the drying layer and sending it into the horizontal tubes. This allows the dried air to be evenly distributed inside the casing, and combined with the absorption of
moisture from the side walls of the casing by drying cotton strips, effectively removing
moisture from the common-enclosed
busbar.
