Abstract
The utility model discloses a three-column amorphous alloy dry-type transformer. The transformer comprises an iron core, a coil, an upper clamping piece, and a lower clamping piece, wherein the iron core includes two iron core frames with rectangular cross sections, the two iron core frames are distributed in sequence side by side, and the iron core is made of amorphous alloy; the coil includes three conductors with round cross sections, the conductors are respectively sleeved on three core columns formed by the two iron core frames, and the external surface of the coil is coated by an insulating material; and the iron core together with the coil sleeved thereon is fixed between the upper clamping piece and the lower clamping piece. The utility model has the advantages of simple structure, light weight and compact structure, greatly reduces the floor space of the transformer, lowers the production cost and the operation depletion of the transformer, and raises the utilization ratio of the iron core; and besides, the energy-saving effect of the iron core of a distribution transformer is comparatively ideal at present.
Description
Technical field
The utility model relates to the technical field of transformer, more particularly relates to the technical field of amorphous alloy transformer.
Background technology
Fast development along with Chinese national economy, country is progressively strengthening the power construction input, to solve the disparities between supply and demand of current power anxiety, power transformer is the important power consumption equipment of China's urban distribution network and rural power grids, be directly connected to electricity quality and energy-saving and cost-reducing problem, under the severe day by day background of world energy sources general layout, energy-saving and emission-reduction have become the fundamental state policy of China, at present, range transformer adopts the grain oriented silicon steel sheet material of colding pressing to make the iron core of transformer mostly, adopt the iron core of this kind made because its no-load loss is big, make the loss height of transformer self-operating, be staff's problem of making great efforts to solve in the industry always, and what iron core adopted mostly at present in addition is four frame pentastyle structures, this structure has not only increased the weight of transformer self, but also has wasted a large amount of core materials.
The utility model content
The purpose of this utility model provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, and no-load loss is low, and is in light weight, and three energy-conservation pillar amorphous alloy dry-type transformers.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Three pillar amorphous alloy dry-type transformers, comprise iron core, coil, upper clamping piece and lower clamping piece, described iron core is made of two rectangular iron core frames of cross section, and successively and column distribution, this iron core adopts amorphous alloy material to make, and described coil is made of three rounded conductors of cross section, and it is nested with respectively on three stem stems that formed by two iron core frames, described coil outer surface is enclosed with insulating material, and iron core together is fixed between upper clamping piece and the lower clamping piece together with the coil that is nested with on it.
Described insulating material is the epoxy insulation resin.
Described coil is made of 2-4 group high pressure winding and 2-4 group low pressure winding, and each high pressure winding correspondence respectively is positioned at each low pressure winding outside.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the utility model is simple in structure, adopt amorphous alloy material to make iron core, it descends about 75% than the transformer noload losses of adopting silicon steel material to make iron core, no-load current descends about 80%, it is the comparatively ideal distribution transformer iron core of present energy-saving effect, being specially adapted to the lower place of rural power grids and developing region even load rate uses, iron core only adopts two iron core frames to constitute, in light weight, saved the material of making iron core, compact conformation, reduced the floor space of transformer greatly, greatly reduce production cost, reduced the running wastage of transformer, improved the utilance of iron core.Adopt the dry-type transformer of epoxy insulation resin-cast also to have its more following advantages in addition:
1, the overall mechanical strength of molded coil is good, the ability of tolerance short circuit is strong: because epoxy resin mobile performance at a certain temperature is fine, adopt advanced pouring technology, cast and will form a complete rigid body in mould through the coil of solidified forming, the axial electric power or the width of cloth during no matter to sudden short circuit all have very strong tolerance to electric power, owing to there is not this class strong point of cushion block, so lead can not bear bending stress, thereby the mechanical strength height can be thought the great advantage of epoxy insulation resin casting dry-type transformer;
2, the superpotential performance of withstand shock is good, and benchmark impact-level (BIL) value is high;
3, protection against the tide and decay resistance are good especially, especially be fit to work under the exceedingly odious environmental condition: for the dry-type transformer of epoxy insulation resin-cast, because the whole winding conductor is all sealed by the solid insulating layer of epoxy resin, thereby not only moisture is difficult to immerse, and blocked conductor fully by the possibility of various pernicious gases and the infringement of aggressive chemistry composition, thereby its moistureproof and antifouling performance is good especially, and can work under the exceedingly odious environmental condition;
4, can be immediately put into operation and need not preheating under the stand-by state and remove tide: the dry-type transformer of epoxy insulation resin-cast, because its protection against the tide, anti-dust performance are good, thereby there is not necessity of this preheating fully, dry-type transformer in stopping transport can be put into operation and load carrying immediately according to the needs of electrical network;
5, loss is low, capability of overload is strong: for epoxy insulation resin filled type dry-type transformer, the proof voltage intensity of epoxy insulation resin is than air high (about 3.5～4 times), its coil is sealed the resin bed into 2mm, because the nominal loss and the specified temperature rise of epoxy insulation resin casting dry-type transformer are low, advantage with energy savings, environmental protection, because specified temperature rise is low, its capability of overload is strong simultaneously.
