Tight bus duct

Abstract

The invention relates to the technical field of electric transmission and transformation equipment, in particular to a tight bus duct. The tight bus duct comprises an upper cover plate, a lower cover plate, a left side plate and a right side plate, wherein the upper cover plate and the lower cover plate are connected to the two ends of the left side plate respectively and are connected to the two ends of the right side plate respectively, the inner side and the outer side of the upper cover plate are provided with a pressing plate and a wheel disc respectively, and the pressing plate is connected with the wheel disc through a screw rod. The inner side and the outer side of the upper cover plate are provided with the pressing plate and the wheel disc respectively, the pressing plate is connected with the wheel disc through the screw rod, in the using process, the height of the pressing plate can be adjusted by rotating the wheel disc, the pressing function is performed on a bus, loosening is prevented, so that the electric conductivity and the working stability of the bus are improved, and the safety of power transmission is greatly improved.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation equipment, in particular to a compact bus duct. Background technique [0002] In the prior art, the intensive busway structure is a combined structure of cover plate and side plate. The small ribs (fixed parts) on both sides of the upper and lower cover plates are used to clamp the left and right side plates at the same time, and the cover plate and side plate punch holes are fixed by bolts. Although This structure can connect the side cover of the busbar. However, when installing the busbar, due to the fixed volume, it cannot be adjusted, resulting in the loosening of the busbar, which affects the conductivity and working stability of the busbar, and there are certain safety hazards. Contents of the invention [0003] In order to overcome the shortcomings of the existing dense busway that easily loosen the busbar and affect the conductivity and stability, the inven...
