Abstract
The utility model relates to a combined distribution transformer which adopts a plane lamination-typed three-phase three-column iron core; the transformer is characterized in that a high-voltage coil is taken as an aluminium lead coil and a low voltage coil is taken as a copper lead coil. The combined distribution transformer ensures all performance indexes of the product and reduces the dosage of copper material, thus reducing the cost of the product and saving the copper resource.
Description
Technical field
The utility model relates to power equipment, and a kind of electric pressure of more specifically saying so is that 10KV/0.4KV, capacity are the oil immersion-type distribution transformer of 10-1600KVA.
Background technology
At present, at electric pressure is that 10KV/0.4KV, capacity are S9, the S11 type distribution transformer of 10-1600KVA, usually high-tension coil and low-voltage coil all are to adopt the copper conductor coiling, and iron core is the folded core structure in plane, selects for use the 25# transformer oil as insulation and heat eliminating medium simultaneously.This version copper material consumption is big, because preciousness, the price height of metallic copper resource cause the product cost height.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point, providing a kind of copper aluminium combined distribution transformer, under the prerequisite that guarantees the every performance index of product, reduces product cost by the consumption that reduces copper material, saves the copper resource.
The utility model technical solution problem adopts following technical scheme.
Version of the present utility model is to adopt the stacked three-phase three-column iron core in plane.
Design feature of the present utility model is that high-tension coil is set is the aluminum conductor coil, and low-voltage coil is set is the copper conductor coil.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model aluminium lead Alloy instead of Copper lead is manufactured high-tension coil, has reduced the production cost of transformer, saves copper material, alleviates the nervous situation of copper resource.
2, the utility model adopts plane laminated core structure structure, because of with the S11 type distribution transformer of capacity no-load loss that is core loss low 30% than S9 type distribution transformer, therefore select for use the cold-rolled orientation silicon steel sheet of unlike material to make S9. and S11 type distribution transformer cores, and coil is selected same spline structure for use, produce S9, S11 type distribution transformer respectively, it is convenient to produce.
Description of drawings
Fig. 1 is the core structure schematic diagram.
Fig. 2 is an iron core A-A sectional drawing shown in Figure 1.
Fig. 3 is the utility model loop construction schematic diagram.
Fig. 4 is the utility model coil plan structure schematic diagram.
Number in the figure: 1 high-tension coil, 2 low-voltage coils, 3 iron cores, 4 oil ducts.
Below, in conjunction with the accompanying drawings the utility model is further described by embodiment.
Embodiment
Referring to Fig. 1, Fig. 2, present embodiment adopts the three-phase three-column iron core 3 of plane laminated structure, and iron core is 45 degree full bias seams of conventionally form, and material unshakable in one's determination also selects for use 30Q130 and 27QG120 orientation silicon steel sheet to manufacture S9 and S11 iron core respectively.
Referring to Fig. 3, Fig. 4, in the present embodiment, high-tension coil 1 is set is the aluminum conductor coil, form specifically adopts electric insulation paper bag aluminum conductor to make routinely; Low-voltage coil 2 is set is the copper conductor coil, also form specifically adopts insulating paper bag oxygen-free copper lead to make routinely, is oil duct 4 between high-tension coil 1 and the low-voltage coil 2.At S9 and S11 iron core, loop construction is set to identical, can use mutually.
In concrete the enforcement, distribution transformer adopts the 25# transformer oil to make insulation and heat eliminating medium, and through actual detected, every performance index all meet existing national standard.
Claims (2)
1, the combined distribution transformer of copper aluminium adopts the stacked three-phase three-column iron core in plane (3), and it is characterized in that being provided with high-tension coil (1) is the aluminum conductor coil, and low-voltage coil (2) is set is the copper conductor coil.
2, the combined distribution transformer of copper aluminium according to claim 1 is characterized in that the stacked three-phase three-column iron core in described plane (3) is a material with 30Q130 or 27QG120 orientation silicon steel sheet.
