Abstract
The utility model discloses an energy-saving roll iron core transformer comprises roll iron cores, upper clamping plates, lower clamping plates and windings, wherein the upper clamping plates and the lower clamping plates are used for clamping the roll iron cores. The roll iron cores are arranged in a shape of homocentric squares, the number of the roll iron cores is four, the four roll iron cores are sequentially contacted and connected with each other, the number of the windings is three, and the three windings are respectively arranged on the connecting portions of every two roll iron cores. The four roll iron cores are tightly arranged, the upper clamping plates and the lower clamping plates clamp the roll iron cores, structure is enabled to be compact, and therefore space utilization rate is high. Zero sequence magnetic flow flows through two iron core columns which are not connected with the windings and are arranged on two sides of the transformer in the roll iron cores, magnetic flow does not flow through the case body of the transformer, heat loss of structure is not generated, and the effects of low operation noise and small no-load loss are achieved.
Description
Technical field
The utility model relates to a kind of transformer, and more particularly, it relates to a kind of energy-conservation coil iron core dry-type transformer.
Background technology
In electric power system, general steam turbine transformer, boiler transformer, ash disposal transformer, dust removing transformer, desulfurization transformer etc. all are dry-type transformers, dry-type transformer just refers to that iron core and winding are not immersed in the transformer in the insulating oil, rely on cross-ventilation to cool off, generally be used for localized lighting, electronic circuit.
The be in operation noise that produces of dry-type transformer mainly is that the magnetostriction that silicon steel sheet produces during by the iron core excitation causes that the size of iron core diameter, magnetic flux density and iron core manufacturing process have a direct impact transformer noise.In manufacturing process, the noise that the unreliable meeting of the fastening degree of iron core produces when making core vibration is propagated out by coupled object, directly causes the increasing of noise.The present main laminated core structure that adopts, Existential Space takies greatly, high material consumption, the relatively large drawback of no-load loss.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of energy-conservation coil iron core dry-type transformer with space availability ratio height, compact conformation, running noises is low, no-load loss is little power savings.
For achieving the above object, the utility model provides following technical scheme: a kind of energy-conservation coil iron core dry-type transformer, comprise the volume iron core, be used for clamping train wheel bridge and the lower plate of volume iron core and be wrapped in the winding of rolling up on the iron core, described volume iron core is the structure setting of " returning " shape and is provided with four, the connection of conflicting successively of described four volume iron cores, described winding is provided with three, and places respectively the junction of per two volume iron cores.
By adopting technique scheme, roll up the iron core close-packed arrays for four, and have train wheel bridge and lower plate that the volume iron core is clamped, so that compact conformation, thereby had higher space availability ratio; Two iron core column that are arranged in both sides that do not connect winding in the volume iron core flow through the zero sequence magnetic flux, and magnetic flux does not produce the structural loss of heating without transformer-cabinet, reaches the power savings that running noises is low, no-load loss is little.
The utility model further is set to: described volume iron core is provided with two rows at least, every row roll up iron core all be provided with side by side four and per two the volume iron cores junctions be equipped with winding
By adopting technique scheme, further reduce running noises low, reduce no-load loss.

Fig. 2 is the left view of the energy-conservation coil iron core dry-type transformer embodiment of the utility model;
Fig. 3 is the vertical view of the energy-conservation coil iron core dry-type transformer embodiment of the utility model;
Fig. 4 is the fit structure schematic diagram of volume iron core and winding.
Embodiment
Referring to figs. 1 through Fig. 4 the energy-conservation coil iron core dry-type transformer embodiment of the utility model is described further.
A kind of energy-conservation volume iron core 1 dry-type transformer, comprise volume iron core 1, be used for clamping train wheel bridge 3 and the lower plate 4 of volume iron core 1 and be wrapped in the winding 2 of rolling up on the iron core 1, described volume iron core 1 is the structure setting of " returning " shape and is provided with four, the connection of conflicting successively of described four volume iron cores 1, described winding 2 is provided with three, and places respectively the junction of per two volume iron cores 1.
By adopting technique scheme, roll up iron core 1 close-packed arrays for four, and have train wheel bridge 3 and 4 pairs of volumes of lower plate iron core 1 to clamp, so that compact conformation, thereby had higher space availability ratio; Two iron core column (can be described as other post 11) that are arranged in both sides that do not connect winding 2 in the volume iron core 1 flow through the zero sequence magnetic flux, and magnetic flux does not produce the structural loss of heating without transformer-cabinet, reaches the power savings that running noises is low, no-load loss is little.
As shown in Figure 3, described volume iron core 1 is provided with two rows at least, every row roll up iron core 1 all be provided with side by side four and per two the volume iron cores 1 junctions be equipped with winding 2.
By adopting technique scheme, further reduce running noises low, reduce no-load loss.
