An Investigation of Winding Curvature Effect on the Mechanical Strength of Transformer Windings
During the winding process of a transformer, a residual strain is induced in its windings conductors. In this paper, the effect of the strain on the mechanical strength of transformer windings under the worst case condition of the short circuit has been investigated. The distribution of the residual...

In this paper, the effect of the strain on the mechanical strength of transformer windings under the worst case condition of the short circuit has been investigated. The distribution of the residual strain in the conductors during its winding process has been determined analytically. The strain induced in the conductors under the action of radial short-circuit forces has been computed. The two strains are then added to obtain a resulting strain. By using the Ramberg-Osgood stress-strain relation of the conductor (copper) material, resulting stress is determined. A case study has been given where the presence of residual strain in the conductors of a power transformer has been taken into account for determining its mechanical strength under the worst case condition of short circuit. | ||

The strain induced in the conductors under the action of radial short-circuit forces has been computed. The two strains are then added to obtain a resulting strain. By using the Ramberg-Osgood stress-strain relation of the conductor (copper) material, resulting stress is determined. A case study has been given where the presence of residual strain in the conductors of a power transformer has been taken into account for determining its mechanical strength under the worst case condition of short circuit.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">transformer winding mechanical strength</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Materials</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">manufacturing stress</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Windings</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">conductors (electric)</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Stress</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">residual strain</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">winding curvature effect</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Strain</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">radial short-circuit force</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Force</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">transformer windings</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ramberg-Osgood stress-strain relation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">transformers</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">power transformer conductor</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Electromagnetic force</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">short circuit</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">power transformers</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">residual strain distribution</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Conductors</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">stress-strain relations</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">mechanical strength</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">short-circuit currents</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">IEEE transactions on power delivery</subfield><subfield code="d">New York, NY : IEEE, 1986</subfield><subfield code="g">30(2015), 4, Seite 1821-1826</subfield><subfield code="w">(DE-627)129382914</subfield><subfield code="w">(DE-600)165807-4</subfield><subfield code="w">(DE-576)014769328</subfield><subfield code="x">0885-8977</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:30</subfield><subfield code="g">year:2015</subfield><subfield code="g">number:4</subfield><subfield code="g">pages:1821-1826</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">http://dx.doi.org/10.1109/TPWRD.2015.2410775</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=7056484</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-TEC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_30</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2014</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2016</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2061</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">30</subfield><subfield code="j">2015</subfield><subfield code="e">4</subfield><subfield code="h">1821-1826</subfield></datafield></record></collection>

An Investigation of Winding Curvature Effect on the Mechanical Strength of Transformer Windings |
| abstract |
During the winding process of a transformer, a residual strain is induced in its windings conductors. In this paper, the effect of the strain on the mechanical strength of transformer windings under the worst case condition of the short circuit has been investigated. The distribution of the residual strain in the conductors during its winding process has been determined analytically. The strain induced in the conductors under the action of radial short-circuit forces has been computed. The two strains are then added to obtain a resulting strain. By using the Ramberg-Osgood stress-strain relation of the conductor (copper) material, resulting stress is determined. A case study has been given where the presence of residual strain in the conductors of a power transformer has been taken into account for determining its mechanical strength under the worst case condition of short circuit. |
