Abstract
The utility model relates to a magnetic shunt structure of a transformer, which is formed by a magnetic shunt arranged on the transformer. The magnetic shunt comprises an upper magnetic shunt and a lower magnetic shunt which are respectively arranged above a press plate of the transformer and under a support plate, the upper magnetic shunt and the lower magnetic shunt are overlapped by a plurality of silicon sheets, and a double-H glue layer is glued among the silicon sheets. The magnetic shunt structure has the beneficial effects that the upper magnetic shunt and the lower magnetic shunt which are overlapped by the silicon sheets are respectively arranged above the press plate of the transformer and under the support plate, so that the problems that the leakage magnetic flux which enters into a structure piece and the transverse leakage magnetic flux at the end of a coil can be effectively reduced, the eddy-current loss and the magnetic hysteresis loss of the structure piece can be reduced, the local overheating phenomenon of some structure pieces can be effectively controlled, and the larger load noise caused by the entering of the flux leakage generated by a load current can be further reduced.
Description
Technical field
The utility model relates to a kind of transformer magnetic shunt structure, belongs to generating, power transformation and distribution technique field.
Background technology
Because electric power development recently is very fast, the transformer developing trend is big in capacity, the impedance height.Big capacity, the leakage field of high-impedance transformer is also relatively large, and the stray loss of transformer is wayward, some structural member even the local overheating phenomenon occurs, transformer load loss also increases greatly.
The leakage field that produces because of load current for control transformer inside causes structural member local overheating phenomenon and reduces transformer stray loss and load noise, need invention design is a kind of can to reduce structural member eddy current loss and magnetic hysteresis loss, and can control the transformer magnetic shunt structure that the local overheating phenomenon appears in some structural member effectively.
Summary of the invention
The utility model provides a kind of transformer magnetic shunt structure at the deficiencies in the prior art, to reach the purpose that leakage field that control transformer inside produces because of load current causes structural member local overheating phenomenon and reduces transformer stray loss and load noise.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of transformer magnetic shunt structure, be to constitute by the magnetic shunt that is installed on the transformer, described magnetic shunt comprises upper and lower magnetic shunt, it is installed on the pressing plate top and the supporting plate below of transformer respectively, described upper and lower magnetic shunt is formed by stacking by a plurality of silicon steel sheets, and adhesion has a pair of H glue-line between described each silicon steel sheet.
The beneficial effects of the utility model are: by the pressing plate top and the supporting plate below that will be installed on transformer by the upper and lower magnetic shunt that a plurality of silicon steel sheets are formed by stacking, the leakage flux that enters in the structural member and the problem of the horizontal leakage flux of end winding have been reduced effectively, reduce structural member eddy current loss and magnetic hysteresis loss, and controlled some structural member effectively and the local overheating phenomenon occurred, the leakage field that also reduces the load current generation enters its load noise inner and generation is bigger.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described upper and lower magnetic shunt is clamped in the pressing plate top and the supporting plate below of transformer by first, second securing member.
Further, described first, second securing member constitutes by bolt, butterfly spring, wood clamp spare and nut.
Adopt the beneficial effect of above-mentioned further scheme to be, make magnetic shunt can be fixed on the below of pressing plate top and supporting plate firmly.
Further, outermost one deck silicon steel sheet of described upper and lower magnetic shunt and ground strip welding, described ground strip is connected by earth stud with folder, and described folder passes through cable grounding.
Further, outermost one deck silicon steel sheet of described upper and lower magnetic shunt is gone back half lap outward and is wound with an epoxy and does not have latitude glass fiber belt.
Further, described epoxy does not have latitude glass fiber belt outsourcing bundle one insulating paper flaggy is arranged.
