One end of the second busbar passes through the casting case, the first groove is placed in the second insulating polyester body, one end of the fifth busbar passes through the casting case, and the first groove is placed in the second insulating polyester body In the body, one end of the first busbar, the third busbar, and the fourth busbar is placed in the first insulating polyester body through the casting shell;

The second busbar assembly includes a sixth busbar, a seventh busbar, an eighth busbar, a ninth busbar and a tenth busbar from top to bottom, the sixth busbar, the seventh busbar, Both ends of the eighth busbar and the ninth busbar are placed in the second insulating polyester body through the casting shell, and are respectively connected with the fifth busbar, the fourth busbar, the third busbar and the second busbar. The tenth busbar passes through the casting shell and is placed in the first insulating polyurethane, and is connected with the first busbar.

In the above-mentioned phase-commutation busway unit, the distance d1 from the edge of the cast case to the first busbar and the fifth busbar is 30 mm.

The above-mentioned phase-commutation busway unit, wherein, the distance d2 between the first busbar, the second busbar, the third busbar, the fourth busbar and the fifth busbar is all 15mm.

The beneficial effects of the utility model are:

Connect the utility model with two busbars, because the first busbar, second busbar, third busbar, fourth busbar and fifth busbar on one side of the casting shell, the sixth busbar on the other side , The seventh busbar, the eighth busbar, the ninth busbar and the tenth busbar, the reverse order of the busbars is realized by the connection relationship, so that two oppositely installed busbars can be switched.

In the utility model, d1 is 30mm, and d2 is 15mm, which can ensure a larger creepage distance, better insulation, and better adaptability to the bus duct; through the first insulating polyester body and the second insulating polyester body , Improve the sealing stability, and the pouring shell is fire-resistant and waterproof, and the quality is light.

To sum up, the utility model is beneficial to transfer two bus ducts in the installation direction of the bus duct and busbar, so as to ensure the installation of electricity, improve the installation flexibility, reduce losses, and has high practical value.
