A busbar splicing method, characterized in that: The following steps are involved: Arrange a plurality of insulating partitions between two limiting side plates, so that the first connection hole of each insulating partition and the second connection hole of each limiting side plate are on the same straight line, and pass fasteners through the first connection hole and the second connection hole to complete the assembly of the bus duct connector; Align the first connection port with the bus duct connector so that the inner end surfaces of the two first inner conductors are respectively aligned with the two side surfaces of the first partition, and the inner end surfaces of the two first outer conductors are respectively aligned with the outer side surface of a second partition; Connecting the bus duct connector to the first connection port, so that the inner end surfaces of the two first inner conductors are respectively in contact with the two side surfaces of the first partition, and the inner end surfaces of the two first outer conductors are respectively in contact with the outer side surface of a second partition; Aligning the second connection port with the bus duct connector so that the outer end surface of the second inner conductor is aligned with the inner side surface of the second partition, and the outer end surface of the second outer conductor is aligned with the inner side surface of the third partition; The second connection port is docked with the bus duct connector, so that the outer end surface of the second inner conductor abuts against the inner side surface of the second partition, and the outer end surface of the second outer conductor abuts against the inner side surface of the third partition, so that a lap joint module formed by staggered lap joints of the first inner conductor and the second inner conductor is formed between the first partition and the second partition, and a lap joint module formed by staggered lap joints of the first outer conductor and the second outer conductor is formed between the second partition and the third partition; Tighten the fasteners to complete the busbar overlap.
9. The busbar splicing method according to claim 8, characterized in that: When the first connection port and the second connection port are connected to the bus duct connector, the connection groove of the first connection conductor is clamped on the limiting protrusion of the insulating partition.
10. The busbar splicing method according to claim 8, characterized in that: Calibration protrusions are provided on the outer sides of the first connection port and the second connection port. After the first connection port is docked with the second connection port and the bus duct connector, the accuracy of the overlapping position can be judged by the relative position between the calibration protrusion and the limiting side plate, and the relative positions of the first connection port, the second connection port and the bus duct connector are calibrated.
