DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0021] like Figure 1-Figure 7 As shown, ports 5-a are provided on both sides of the tee shell 5, and a branch port 5-b is provided in the middle. The disc insulator 1 is provided with an insert conductor 1-a distributed in an equilateral triangle. The tee shell 5 includes a tee shell 1 5-1, and the disc insulator 1 includes a disc insulator 1-1 and a disc insulator 2 1-2. The disc insulator 1-1 and the disc insulator 2 1-2 are respectively arranged at the branch port 5-b and a port 5-a of the tee shell 1 5-1. One side of the insert conductor 1-a of the disc insulator 1-1 is connected to the connecting conductor 1 2, and the connecting conductor 1 2 is vertically connected to the connecting conductor 2 4. The connecting conductor 2 4 is connected to the insert conductor 1-a of the disc insulator 2 1-2 through the transposition shield 3; the insert conductor 1- One side of the equilateral triangle formed by a is close to and parallel to the plane where the disc insulator 2 1-2 is located. The connecting conductor 1-2 includes two short links 1-1 and one long link 1-2. The height difference between the short link 1-1 and the long link 2-2 is equal to the height of the equilateral triangle. The short link 1-1 is connected to the embedded conductor 1-a at both ends of one side parallel to the plane where the disc insulator 2 1-2 is located. The long link 1-2 is connected to another embedded conductor 1-a. The connecting conductor 2-4 includes two short links 2-1 and one long link 2-2. The height difference between the short link 2-1 and the long link 2-2 is equal to the height of the equilateral triangle. The short link 1-1 is vertically connected to the short link 2-1, and the long link 1-2 is vertically connected to the long link 2-2.

[0022] The side surfaces of the long connecting rod 2-2 and the short connecting rod 2-1 near the end are provided with cylindrical or cylindrical protrusions 2-a, and one end of the long connecting rod 4-2 or the short connecting rod 4-1 is nested on the outside of the protrusion 2-a.

[0023] One end of the transposition shield 3 is nested outside one end of the long connecting rod 2 4 - 2 or the short connecting rod 2 4 - 1 , and the other end of the transposition shield 3 is connected to the insert conductor 1 - a .

[0024] During use, because one side of the equilateral triangle formed by insert conductor 1-a of disc insulator 1-1 is close to and parallel to the plane of disc insulator 2 1-2, and the height difference between long link 1-2 and short link 1-1 is equal to the height of the equilateral triangle, after insert conductor 1-a of disc insulator 1-1 connects short link 1-1 and long link 1-2, the projection of protrusion 2-a on disc insulator 2 1-2 is the same as the equilateral triangle of insert conductor 1-a. Then, one end of short link 2-1 is connected to short link 1-1, and one end of long link 2-2 is connected to long link 1-2. Because the height difference between long link 2-2 and short link 2-2 is equal to the height of the equilateral triangle, the other ends of short link 2-1 and long link 2-2 are aligned in the same plane. The mounting axes at both ends of the transposition shield 3 are different. Through the transposition shield 3, the positions of the short connecting rod 2 4-1 and the long connecting rod 2 4-2 can be reversed to connect with the insert conductor 1-a of the disc insulator 2 1-2, achieving phase commutation. This in turn establishes an electrical connection between the disc insulator 1-1 and the disc insulator 2 1-2.

[0025] Long connecting rod 1 2-2 and short connecting rod 1 2-1 nest with long connecting rod 2 4-2 and short connecting rod 2 4-1 via cylindrical or cylindrical protrusion 2-a, allowing fine adjustment of the position of long connecting rod 2 4-2 and short connecting rod 2 4-2 within the cylindrical fit range. Transposition shield 3 nests with long connecting rod 2 4-2 and short connecting rod 2 4-1, allowing bidirectional adjustment of the position of long connecting rod 2 4-2 and short connecting rod 2 4-1.

[0026] By setting the phase angle at the inlet of the disc insulator 1-1, straight conductors can be used for connection within the three-phase housing 5-1. Reversal is achieved through the transposition shield 3. This simplifies the structure and uses fewer parts. During installation, connections are made based on direction and component length, not phase sequence, making it difficult to make mistakes. Example

[0027] like Figures 8-10As shown, based on the connection structure of the embodiment 1, it also includes a tee shell 2 5-2 and a tee shell 3 5-3, the branch port 5-b of the tee shell 1 5-1 is connected to a port 5-a of the tee shell 2 5-2, the branch port 5-b of the tee shell 2 5-2 is connected to the branch port 5-b of the tee shell 3 5-3, the disc insulator 1-1 is set at a port 5-a of the tee shell 1 5-1, and the disc insulator 2 1-2 is set at the connection between the tee shell 1 5-1 and the tee shell A disc insulator three 1-3 is provided between the two bodies 5-2 and between the three-way shell two 5-2 and the three-way shell three 5-3. One side of the equilateral triangle of the disc insulator two 1-2 is close to and parallel to the plane where the disc insulator three 1-3 is located. The other side of the embedded conductor 1-a of the disc insulator two 1-2 is connected to the connecting conductor one 2. The connecting conductor one 2 is vertically connected to the connecting conductor two 4. The connecting conductor two 4 is connected to the embedded conductor 1-a of the disc insulator three 1-3 through the transposition shielding cover 3.

[0028] In the second embodiment, a tee shell 2 5-2 and a tee shell 3 5-3 are added to the tee connection structure of the first embodiment. One side of the equilateral triangle of the second disc insulator 1-2 is close to and parallel to the plane where the third disc insulator 5-3 is located. In this way, the same connection structure as the tee shell 1 5-1 can be used in the second tee shell 5-2, ensuring the phase sequence and the universality of parts. It can be applied to situations where the segmented connection intervals are large.
