Alternatively, taking 6 wires as an example, as shown in fig. 3, fig. 3 is a front view of a cross section of the 6 wires, and a point in fig. 3 is a cross section of the 6 wires. The 6 wires form three pairs of wires, namely wire pair 302, wire pair 304 and wire pair 306. Wire pair 302 includes wire a and wire B, wire pair 304 includes wire C and wire D, and wire pair 306 includes wire E and wire F. Then, the minimum phase distance between a and B is the horizontal phase distance in the horizontal phase distance set, and the minimum phase distance between a and any one of the wires except B is the vertical phase distance in the vertical phase distance set.
Through the embodiment, the minimum phase distance is divided into the horizontal phase distance set and the vertical phase distance set by the method, the minimum phase distance set is obtained according to the horizontal phase distance set and the vertical phase distance set, and the conducting wire is adjusted, so that the safety of the conducting wire is improved.

For example, the description will be continued with a case where six wires are used. As shown in FIG. 3, the vertical phase spacing includes AC, AD, AE, AF, BC, BD, BE, BF, CE, CF, DE, DF as can BE seen from FIG. 3. At this time, the 12 vertical phase intervals are sorted, and then, the top 4 vertical phase intervals are selected. And the horizontal phase intervals in the horizontal phase interval concentration are AB, CD and EF.

and S1, adjusting the length of the cross arm where the plurality of wires are located under the condition that at least one minimum phase distance in the minimum phase distance set is smaller than or equal to a first threshold value.
Alternatively, the first threshold may be, but is not limited to, a preset empirical value. For example, if any one of the minimum phase distances in the minimum phase distance set is smaller than or equal to the first threshold, it indicates that the phase distance between two wires is too small, which may cause a safety hazard and require adjustment. At this time, the length of the cross arm where the wire is located is adjusted, so that the safety of the wire is ensured.
It should be noted that, since the arrangement of the wires is not unique, the present embodiment provides a method for obtaining the minimum phase distance set for a specific arrangement condition of the wires.
In the plurality of wires of the present embodiment, the wires having the corresponding end points on the same horizontal plane are regarded as being located on the same horizontal plane. For example, as the conductive lines 202 and 204 in fig. 2, the corresponding ends of the conductive lines 202 and 204 are located on the same horizontal plane, and the conductive lines 202 and 204 are regarded as two conductive lines located on the same horizontal plane. The plurality of wires of the present embodiment are located at one horizontal plane or a plurality of horizontal planes. When the plurality of wires are located at a plurality of levels, the number of wires at each level is even.
In this case, after the minimum phase distances of every two wires in the plurality of wires are obtained, all the minimum phase distances are divided into horizontal phase distances and vertical phase distances, and the horizontal phase distances and the vertical phase distances are arranged in the order of the minimum phase distances from small to large, the first M minimum phase distances of the first N minimum phase distances and the vertical phase distances of the horizontal phase distances are extracted, the N minimum phase distances and the M minimum phase distances are combined into a minimum phase distance set, and the lengths of the wires are adjusted according to the minimum phase distance set. Wherein, the N can be obtained by the following method:
and acquiring the number of planes formed by the conducting wires, wherein N is the absolute value of the difference between the number of the conducting wires and the number of the planes formed by the conducting wires.
The above M can be obtained by the following method:
and repeating the following steps until all planes formed by the plurality of leads are traversed, wherein the initial value of i is 1, the value of i is added with 1 every time of traversal, and i is less than the number of the planes formed by the plurality of leads.
And acquiring the number of the wires of the plane with less wires in the ith plane and the (i + 1) th plane.
And after traversing is completed, summing the obtained roots of all the leads to obtain M.
For example, as shown in fig. 4, fig. 4 is a front view of a cross-section of 6 wires, and the point in fig. 4 is a cross-sectional cut of 6 wires. Then AB, CD, CE, CF, DE, DF are included in the corresponding horizontal phase spacing concentration of fig. 4. The first N smaller phase spacings are selected from the set of horizontal phase spacings, and N is 4 (the absolute value of the difference between the number of conductors 6 and the number of planes 2) can be obtained by the method described above. The horizontal phase spacings AB, CD, DE, EF can then be selected. Meanwhile, the first M smaller vertical phase intervals in the vertical phase intervals are selected, and M is 2 (the number of the conducting wires in the plane with fewer conducting wires in the 1 st plane and the second plane) according to the method, so that the vertical phase intervals AD and BE can BE selected. In this case, the minimum phase-to-phase distance sets AB, CD, DE, EF, AD, BE are obtained.

(2) and the determining unit is used for obtaining a minimum phase distance set according to the horizontal phase distance set and the vertical phase distance set.
Alternatively, taking 6 wires as an example, as shown in fig. 3, fig. 3 is a front view of a cross section of the 6 wires, and a point in fig. 3 is a cross section of the 6 wires. The 6 wires form three pairs of wires, namely wire pair 302, wire pair 304 and wire pair 306. Wire pair 302 includes wire a and wire B, wire pair 304 includes wire C and wire D, and wire pair 306 includes wire E and wire F. Then, the minimum phase distance between a and B is the horizontal phase distance in the horizontal phase distance set, and the minimum phase distance between a and any one of the wires except B is the vertical phase distance in the vertical phase distance set.

wherein n islineThe number of the conducting wires is;
(4) and the merging module is used for merging the horizontal phase distance of the N bits before the ranking and the vertical phase distance of the M bits before the ranking into a minimum phase distance set.

The vertical phase spacings in the set of vertical phase spacings may be sorted, in order from smaller to larger, by selecting the first M vertical phase spacings in the set of vertical phase spacings. For example, the description will be continued with a case where six wires are used. As shown in FIG. 3, the vertical phase spacing includes AC, AD, AE, AF, BC, BD, BE, BF, CE, CF, DE, DF as can BE seen from FIG. 3. At this time, the 12 vertical phase intervals are sorted, and then, the top 4 vertical phase intervals are selected.

For example, if any one of the minimum phase distances in the minimum phase distance set is smaller than or equal to the first threshold, it indicates that the phase distance between two wires is too small, which may cause a safety hazard and require adjustment. At this time, the length of the cross arm where the wire is located is adjusted, so that the safety of the wire is ensured.

In the plurality of wires of the present embodiment, the wires having the corresponding end points on the same horizontal plane are regarded as being located on the same horizontal plane. For example, as the conductive lines 202 and 204 in fig. 2, the corresponding ends of the conductive lines 202 and 204 are located on the same horizontal plane, and the conductive lines 202 and 204 are regarded as two conductive lines located on the same horizontal plane. The plurality of wires of the present embodiment are located at one horizontal plane or a plurality of horizontal planes. When the plurality of wires are located at a plurality of levels, the number of wires at each level is even.
In this case, after the minimum phase distances of every two wires in the plurality of wires are obtained, all the minimum phase distances are divided into horizontal phase distances and vertical phase distances, and the horizontal phase distances and the vertical phase distances are arranged in the order of the minimum phase distances from small to large, the first M minimum phase distances of the first N minimum phase distances and the vertical phase distances of the horizontal phase distances are extracted, the N minimum phase distances and the M minimum phase distances are combined into a minimum phase distance set, and the lengths of the wires are adjusted according to the minimum phase distance set. Wherein, the N can be obtained by the following method:
and acquiring the number of planes formed by the conducting wires, wherein N is the absolute value of the difference between the number of the conducting wires and the number of the planes formed by the conducting wires.

and repeating the following steps until all planes formed by a plurality of leads are traversed, wherein the initial value of i is 1, and the value of i is added with 1 every time the planes are traversed.
And acquiring the number of the wires of the plane with less wires in the ith plane and the (i + 1) th plane.
And after traversing is completed, summing the obtained roots of all the leads to obtain M.
For example, as shown in fig. 4, fig. 4 is a front view of a cross-section of 6 wires, and the point in fig. 4 is a cross-sectional cut of 6 wires. Then AB, CD, CE, CF, DE, DF are included in the corresponding horizontal phase spacing concentration of fig. 4. The first N smaller phase spacings are selected from the set of horizontal phase spacings, and N is 4 (the absolute value of the difference between the number of conductors 6 and the number of planes 2) can be obtained by the method described above. The horizontal phase spacings AB, CD, DE, EF can then be selected. Meanwhile, the first M smaller vertical phase intervals in the vertical phase intervals are selected, and M is 2 (the number of the conducting wires in the plane with fewer conducting wires in the 1 st plane and the second plane) according to the method, so that the vertical phase intervals AD and BE can BE selected. In this case, the minimum phase-to-phase distance sets AB, CD, DE, EF, AD, BE are obtained.
