Problems solved by technology
[0002] When the traditional busway is connected between two sections, a special connector is usually used for conductive connection and fixing. The connector is usually composed of intermediate conductive connectors, insulating parts and solid parts. The intermediate conductive connectors It needs to consume more conductive materials, which increases the cost; in addition, because the two busbars are transitionally connected through the intermediate conductive connector, there are many joints, which increases the resistance of the joint part, resulting in serious heat generation and large power transmission loss during operation.

Embodiment Construction
[0010] Such as figure 1 As shown, the structure includes two sections of busbars 1 with opposite ends, and the busbars 11 of each phase on the two sections of busbars form a one-to-one correspondence with multi-phase busbar joints, wherein a through hole 12 is opened on the busbar in one section of the busbar, and Have longitudinal slot 13 (referring to figure 2 ); one end of the through hole has a counterbore 121 with a larger diameter, and the counterbore is facing the bus bar of the adjacent phase, and an insulating sleeve 2 is pierced in the through hole, and one end of the outer diameter of the insulating sheath has a section sunk into the above-mentioned counterbore The other end of the counterbore extends out of the through hole in the stepped section 21 with a larger diameter, and the bus bar with the slot 13 is positioned through the slot and the side of the protruding part of the insulating sleeve to form a bus joint of one phase. There is a layer of insulating pla...

The invention belongs to power transmission and distribution equipment, and relates to a bus duct joint structure used for conductively connecting two transmission and distribution bus ducts, which comprises two bus ducts with opposite end parts, all phase buses on the two bus ducts correspond to each other to form a multiple-phase bus joint, wherein the bus on one bus duct is provided with a through hole, and the bus on the other bus duct is provided with a vertical slot; an insulating sleeve penetrates through the through hole, one end of the insulating sleeve extends out of the through hole, the bus with the slot to be spliced and positioned with the side of the insulation sleeve through the slot, so as to form a one-phase bus joint, an insulating board is arranged between every two adjacent-phase bus joints; a crossing bolt penetrates the insulating sleeve in each one-phase bus joint and the insulation board between every two adjacent-phase bus joints so as to cross and fix the all-phase bus joints. The invention has compact structure, convenient installation, strong insulating property and low temperature rise during the operation.
