It is influenced each other between A × C, variable B and C as B × C, including error comparison column.
Design experiment scheme table simultaneously is completed to test, and this example arranges factor A and factor B to arrange in the 1st column of orthogonal arrage and the 2nd,
So interaction of factor A and factor B is denoted as A × B, A × B be arranged in the 1st column and the 2nd column row, column crosspoint " 3 " and
On " 4 ", then other factors cannot be arranged on the 3rd column and the 4th column, therefore factor C is arranged in the 5th column, then interaction A
× C should be arranged on the row, column crosspoint " 6 " and " 7 " of the 1st column and the 5th column, and interaction B × C should be arranged in the 2nd column

2 first round of table iteration-orthogonal test analysis of variance table
In order to find optimum producting condition, need to introduce the effect of each level.I-th of horizontal effect of factor A is calculated first
It answers, i.e. AiEffect αi, αiCalculation formula beWherein T is the synthesis of all test results,Similarly, B is definedi、Ci... FiEffect bi、ci... fi.Define horizontal AiWith BjCombination to test result produce
Raw gross effect is joint effect, and symbol is denoted as [ab]ij, [ab]ij=μij- μ, wherein μijIt is horizontal AiWith BjIt is equal under combination
Value, μ are the grand mean of all horizontal combinations, horizontal combination AiWith BjReciprocation influence that test result is generated be interaction
Effect is (ab)ij, (ab)ij=[ab]ij-ai-bj。
When selecting best formation condition, it should following principle is generally conformed to, by taking factor A, factor B, factor A × B as an example:
(1) it if factor A, factor B, factor A × B have a significant impact experimental result, should be arranged with two-element list
[ab] outij、αiAnd bi, select [ab]ijIn the maximum [18]；
(2) if factor A, factor A × B have a significant impact experimental result, influence of the factor B to experimental result is less aobvious
It writes, then should be listed with two-element list (ab)ij、αiAnd bi, select interaction (ab)ijWith effect αiIn the maximum [19].
In the embodiment of the present invention, factor A, factor C and reciprocation A × B, reciprocation B × C influence test result aobvious
It writes, the influence of factor B and factor A × C to test result is less significant, so interaction (ab) should be selectedijWith effect αi
In the maximum, interaction (bc)ijWith effect ciIn the maximum.Calculate two-element list such as 3 institute of table of income factor A, factor B
Show, interaction table is as shown in table 4 between factor A, factor B.

4 first round of table iteration-interaction table between orthogonal test factor A and factor B
It can be seen that αiIn maximum value be α3=8.8, followed by α2=7.6, reciprocation (ab)ijMaximum value be A1B1=
19.5, it is secondly A2B3=9.6, A3B2=7.2, so factor A should take A3, with A3The maximum reciprocation of collocation is A3B2=
7.2, therefore factor B takes B2。
It is as shown in table 5 to calculate income factor A, the two-element list of factor C, joint effect table such as 6 institute of table between factor A, factor C
Show.
Effects visible αiMaximum value be α3=8.8, benefit ciMaximum value be c3=13.2, synergy [ac]ijMost
Big value is A3C3=21.0, so factor C should take horizontal C3。
It is other to influence significant factor, including factor D, factor F, the i.e. each K of optimal value is taken respectivelyijIt is maximized, passes through
Comparison, which obtains factor D, should take horizontal D3, factor F should take horizontal F2。
5 first round of table iteration-orthogonal test factor A and factor C two-element list
6 first round of table iteration-joint effect table between orthogonal test factor A and factor C
Factor E can be combined since the influence to test result is not significant by doing three groups of tests again
A3B2C3D3ExF2.When x takes 1,2,3 respectively, obtained test result be respectively 827.756mm/V, 836.132mm/V,
831.318mm/V.Therefore, the optimum producting condition of this test is A3B2C3D3E1F2, ANSYS emulation experiment is done under this condition
As a result as shown in Figure 3.
Sometimes an orthogonal test cannot fully meet engine request, and possible maximum field intensity, which has been still greater than, has stage fright
By force, it is possible to using orthogonal test-iterative method near the optimum producting condition that a upper section acquires iteration, more subtly divide
Factor level, iteration is until meeting engine request.
In present case, iteration is in test combinations A3B2C3D3E1F2Lower progress, wherein A3=300mm, B2=860mm, C3=
3600mm, D3=150mm, E1=550mm, F2=4100mm.The difference of second wheel each factor level of orthogonal test is denoted as △ Q 'A、
△Q′B、△Q′C、△Q′D、△Q′E、△Q′F, it takes respectively:
△Q′A=| A '1-A′2|=| 294-299 |=5；
△Q′B=| B '1-B′2|=| 854-859 |=5；
△Q′C=| C '1-C′2|=| 3590-3601 |=11；
△Q′D=| D '1-D′2|=| 146-151 |=5；
△Q′E=| E '1-E′2|=| 546-551 |=5；
△Q′F=| F '1-F′2|=| 4060-4110 |=50.
Each horizontal specific value of second wheel iteration is as shown in table 7.It calculates with first round orthogonal test, obtains analysis of variance table
8。
In the embodiment of the present invention, since factor C ' and reciprocation B ' × C ' influences significantly test result, factor B ' is right
The influence of test result is not significant, so interaction (bc) should be selectedij', effect cj' in the maximum.Calculate gained because
Plain B ', the two-element list of factor C ' are as shown in table 9, and joint effect table is as shown in table 10 between factor B ', factor C '.
The value of the wheel each variable of iteration of table 7 second
Table 8 second takes turns iteration-orthogonal test analysis of variance table
The two-element list of table 9 factor B ' and factor C '
Interaction table between table 10 factor B ' and factor C '
It can be seen that CiIn maximum value be C1'=2.9, followed by C2'=- 1.3, horizontal C1' lower reciprocation [bc]ij' most
Big value is [bc]31Secondly '=6.2 are [bc]32'=3.6, so factor B' should take B3', factor C' should take C1'。
It is other to influence significant factor, including factor A', factor F ', the i.e. each K of optimal value is taken respectivelyij' be maximized, it passes through
It crosses and compares, factor A', factor F ' horizontal A should be taken respectively3'、F3'。
Influence due to factor D' and factor E' to test result is not significant, can be by doing nine groups of tests again, i.e.,
Combine A3'B3'C1'D3'E2'F1'.When x, y distinguish permutation and combination level 1,2,3, obtained optimum test result is
820.719mm/V, factor D' and E' pairs of factor of optimal level group are combined into D3'E2'.Therefore, the optimum producting condition of this test
For A3'B3'C1'D3'E2'F1', it is as shown in Figure 4 that ANSYS the simulation experiment result is done under this condition.
Second wheel iteration-orthogonal experiments of analysis are it can be found that this time test result is generally speaking more orthogonal than the first round
The experimental result of test method(s) is more excellent, falls below 820.719mm/V by the maximum field intensity around divider after this iteration,
A possibility that corona discharge occurs becomes smaller, and divider accuracy of measurement will be promoted.

Table L27(313), test is completed then according to the testing program of design, with method of analysis of variance development test as a result, passing through the first round
Iteration-orthogonal test has obtained one group of optimal combination scheme, declines maximum field intensity around divider from 4212.5V/mm
To 827.756V/mm, second of iterative test is carried out near this group of optimal combination scheme, keeps maximum field around divider strong
Degree has decreased to 820.719V/mm from 827.756V/mm again.The comparative analysis first round and second wheel iteration-orthogonal experiments
It can be found that this time experimental result of the test result generally speaking than simple orthogonal experiment is more excellent, pass through after this iteration points
A possibility that maximum field intensity around depressor falls below 820.719mm/V, and corona discharge occurs becomes smaller, and divider measurement is quasi-
Exactness will be promoted.This time test, which demonstrates iteration-orthogonal experiment proposed in this paper, to effectively reduce 500kV direct current
