[0033] It should be noted that both the horizontal bending element 1 and the right-angle bending element 5 are cast from volcanic rock inorganic mineral insulating material, which has good electrical insulation and mechanical properties, and can also ensure that the first copper busbar 2 and the second copper busbar 6 are fully wrapped.
[0034] In this embodiment, a horizontal and vertical turning cast busbar element is formed by casting a horizontal bending element 1 and a right-angle bending element 5 through locking. The length of one end of the right-angle bending element 5 can be adjusted. When the turning position is restricted during the construction of the busbar, the positioning rod 10 is moved out of the corresponding positioning hole 9 by pulling the connecting block 11. Then, the telescopic cylinder 8 is pushed into the slide groove 7. Then, the pulling connecting block 11 is released. At this time, the positioning rod 10 can be reset by the elastic force generated by the deformation of the telescopic spring 12, so that the positioning rod 10 springs into the corresponding positioning hole 9, thereby shortening the length of one end of the right-angle bending element 5. In this way, the right-angle bending element 5 can be smoothly placed at one end of the horizontal bending element 1. Then, the connecting block 11 is pulled to restore the telescopic cylinder 8 to the initial position, so that the telescopic cylinder 8 is sleeved on the outside of the first copper busbar 2 and locked to ensure stable installation. At the same time, it can avoid the impact of settlement and prevent deformation and damage.
[0035] The working principle of the above embodiment is as follows: When the right-angle bending element 5 is installed at one end of the horizontal bending element 1, the two connecting blocks 11 can be pulled first to move the two positioning rods 10 out of the corresponding positioning holes 9. At this time, the two telescopic springs 12 are in a stretched state and generate elastic force. Then, the two telescopic cylinders 8 are pushed into the corresponding sliding grooves 7. Then, the pulled connecting blocks 11 are released. In this way, the two positioning rods 10 can be reset by the elastic force generated by the deformation of the telescopic springs 12, so that the two positioning rods 10 spring into the corresponding positioning holes 9, thereby limiting the position of the telescopic cylinders 8. This shortens the length of one end of the right-angle bending element 5, ensuring that the right-angle bending element 5 can be smoothly placed in the installation space, facilitating the installation work at the turning point, and avoiding... To mitigate the impact of settlement and prevent busbar deformation and damage, after placing the right-angle bending element 5, the above steps can be repeated to restore the two telescopic cylinders 8 to their initial extended length. Simultaneously, the two telescopic cylinders 8 will be respectively fitted onto the outside of the two first copper busbars 2, with the first locking hole 4 corresponding to the position of the second locking hole 14. Then, the locking bolts 15 can be screwed between the first locking hole 4 and the second locking hole 14, thereby locking the first copper busbar 2 into the inner wall of the telescopic cylinder 8. At the same time, one end of the first copper busbar 2 will contact one end of the second copper busbar 6 to ensure current transmission. Finally, the connection between the horizontal bending element 1 and the right-angle bending element 5 can be cast, so that the telescopic cylinder 8 and the locking bolts 15 can be cast into the volcanic rock inorganic mineral insulation material.
