As shown in fig. 1 to 3, the bus bar assembly of the present invention includes a front-section bus bar a, a rear-section bus bar B, and a bus bar connection structure connecting the front-section bus bar a and the rear-section bus bar B, where the bus bar connection structure includes a corrugated tube 1 having two ends respectively connected to the front-section bus bar a and the rear-section bus bar B, and a flow guide bar assembly conductively connecting the front-section bus bar a and the rear-section bus bar B, and the flow guide bar assembly includes a first flow guide bar 3 and a second flow guide bar 2. The first guide rows 3 are symmetrically arranged at the left side and the right side of the corrugated pipe 1, and the second guide rows 2 are symmetrically arranged at the upper side and the lower side of the corrugated pipe 1. First water conservancy diversion is arranged 3 and is included anterior segment 31 and back end 32, and anterior segment 31 and back end 32 pass through articulated shaft 33 articulated connection, and the axis of articulated shaft 33 extends and the extending direction of perpendicular to bellows 1 along the horizontal direction, and the free end of anterior segment 31 and back end 32 is connected with anterior segment generating line A and back end generating line B electrically conductive respectively. The second guide row 2 is in a wave shape in the longitudinal section, so that when the corrugated pipe deforms, the second guide row can deform to adapt to the deformation of the corrugated pipe.
Connecting flanges are arranged at the front end and the rear end of the corrugated pipe 1, the connecting flange is also arranged at the joint of the front section bus A and the rear section bus B, and the front section corrugated pipe and the rear section corrugated pipe are connected with the connecting flanges on the corrugated pipe 1 through respective flanges. The free end of the front section 31 of the first diversion row is provided with a front section installation part 34 bent towards the inner side of the corrugated pipe, the free end of the rear section 32 is provided with a rear section installation part 35 bent towards the inner side of the corrugated pipe, and the front section installation part 34 and the rear section installation part 35 are connected to a connecting flange of a front section bus and a rear section bus through bolts.
