As shown in fig. 17, in a split axle case G67, support bodies belonging to different support body matrices, specifically, a-phase insulating support 718, B-phase insulating support 719, and C-phase insulating support 720 are provided on the top and bottom surfaces of the axle case to connect the a-phase connecting bus bar 51, the B-phase connecting bus bar 52, and the C-phase connecting bus bar 53, respectively.

The in-process that the line was walked towards split axle housing H from split axle housing A to three-phase connection generating line is by lieing in the same layer earlier, and the state of walking the line side by side to the three-phase, and the support through the supporter in the split axle housing changes into the mode that two-layer was parallel about being divided in the split axle housing, and the reversing insulation pillar through setting up in split axle housing H at last resumes to the state that the line was walked side by side to the three-phase to the realization is when two cubical switchboard are arranging with "face-to-face" mode, two cubical switchboard phase sequence one-to-one.

Example 2 of the bus bridge of the invention: the difference with the above-mentioned embodiment is that in this embodiment, two sets of supporting bodies are arranged perpendicularly on the left inner wall and the right inner wall of the axle housing, so that the three-phase connecting bus bar is divided into two layers arranged left and right in the axle housing.

Example 3 of the bus bridge of the invention: the difference with the above-mentioned embodiment lies in that two sets of supporters are connected simultaneously on the diapire or the top of axle housing in this embodiment, and the support height of two sets of supporters is different to make the three-phase connection generating line that corresponds stagger in the vertical direction, thereby divide into two-layerly in the vertical direction.

Example 4 of the bus bridge of the invention: the difference with the above-mentioned embodiment lies in that two sets of support body in this embodiment are arranged and are connected on the left side inner wall and the right side inner wall of axle housing, and every support body is L shape to make three-phase connection generating line still divide into upper and lower two-layer in the axle housing.

Example 5 of the bus bridge of the invention: the difference from the above embodiment is that in this embodiment, the three-phase bus bar is divided into an upper layer and a lower layer by the insulating pillars with different heights after entering the axle housing arranged horizontally.

Example 6 of the bus bridge of the invention: the difference from the above embodiment is that the axle housing in this embodiment is of an integrated structure, and is not limited to the split axle housing in the above embodiment.

Example 7 of the bus-bridge of the invention: the difference from the above embodiment is that the support body in this embodiment is integrally formed on the inner wall of the axle housing, and is not limited to the solution that is additionally mounted on the inner wall of the axle housing.

Example 8 of the bus bridge of the invention: the difference with the above embodiment is that the support body in this embodiment is formed by stacking the insulating gaskets, and the height of the support body is changed by adjusting the number of the insulating gaskets, so as to change the relative distance between the three-phase connecting bus and the inner wall of the axle housing.

The bus bar phasing method of the present invention will now be described in detail with reference to the bus bar bridge of the present invention.

Because the three-phase bus wiring terminals are not corresponding when the switch cabinets are arranged in a face-to-face mode, the bus phase modulation method in the invention enables the corresponding phases on the two switch cabinets to be communicated by changing the position of the connecting bus connected between the two switch cabinets.

Specifically, arrange the supporter that is used for supporting the connection generating line in the generating line bridge of connecting two cubical switchboard, through the position of adjustment supporter, make the supporter relative same benchmark and have different support heights in the generating line bridge, when supporting the connection generating line, the connection generating line can be because of the difference of the support point position that the supporter provided, and divide into upper and lower two-layer in the generating line bridge, or divide into to walk the line, walk the line to the right side by the left side.

Because the switch cabinet commonly used in the prior art adopts a three-phase wire inlet and outlet mode, the insulating support columns serving as the supporting bodies are arranged on the inner wall surface and the bottom wall of the top of the axle housing in the bus bar bridge embodiment 1 and the bus bar bridge embodiment 2, so that the three-phase connecting bus bar of the switch cabinet is wired in the bus bar bridge. A connecting bus 51A, a connecting bus 52B and a connecting bus 53C are connected between the switch cabinets, wherein two phases of the connecting buses are wired in parallel, and the other connecting bus is wired in a direction parallel to the other two phases of the connecting buses.

In the wiring process, the interval between the upper and lower connecting buses can be used as a space for exchanging the positions of the A connecting bus 51, the B connecting bus 52 and the C connecting bus 53, the wiring direction of the connecting buses is changed by selecting proper insulating support columns to be used as phase modulation support bodies, so that the connecting buses jump among all insulating support column matrixes, namely different insulating support column matrixes can be used for supporting the same three-phase connecting bus, and finally the two ends of the connecting buses are respectively connected with the same three-phase bus wiring terminals.

The sequence of phase modulation of the A-phase connecting bus 51, the B-phase connecting bus 52 and the C-phase connecting bus 53 is not limited, and only the phase modulation positions of the three phases need to be staggered in the wiring direction, so that two-two interference is avoided.

In other embodiments, the two sets of bus bars may be divided into two layers along the left-right direction, and are not limited to the scheme of layering in the up-down direction.

In other embodiments, the three-phase connecting bus bars may be layered while being routed in the horizontal direction, and are not limited to being layered while being turned from vertical to horizontal.

In other embodiments, the three-phase connection mother phase modulation can be realized by adopting the switching conductor with the shape separately designed according to the phase modulation position, and is not limited to the scheme of adopting the insulating support through different positions.
