Embodiment
As shown in the figure, a kind of connection busbar for being used to get in touch with cabinet, including contact cabinet phase line 4,5,6 and adjacent cabinet are connected respectively
Body corresponds to the A phases busbar 1, B phases busbar 2, C phases busbar 3 of phase line 7,8,9, real by A phases busbar 1, B phases busbar 2, C phases busbar 3
Now get in touch with being electrically connected for cabinet and adjacent cabinet；A phases busbar 1, B phases busbar 2, be coated with insulating layer outside C phases busbar 3 respectively, carries
High safety performance；A phases busbar 1, B phases busbar 2, C phases busbar 3 have U-shaped structure on frontal plane of projection；The two sides of B phases busbar 2
For vertical height higher than A phases busbar 1,3 two sides vertical height of C phases busbar, A phases busbar 1, C phases busbar 3 have identical section shape
Shape；A phases busbar 1,3 two sides vertical curve of C phases busbar make it that side longitudinal cross-section is L-shaped；A phases busbar 1,3 edge of C phases busbar
Cabinet phase line center line is symmetrically installed so that A phases busbar 1, B phases busbar 2, the " u "-shaped connection base of 3 three-phase bus bar of C phases busbar
It is easy for installation respectively along three directional spredings of reference axis in longitudinal projection, occupy little space.
A phases busbar 1, B phases busbar 2,3 section of C phases busbar are circle, and A phases busbar 1, B phases busbar 2,3 both ends of C phases busbar are divided
The rectangle contiguous block being adapted with cabinet phase line connecting sleeve inner cavity is not provided with, connection through hole is provided with contiguous block, and A phases are female
