The purpose of this utility model is in order to overcome the shortcoming of prior art, provide a kind of three-phase magnetic circuit balance, waveform good, energy-conservation, economize material, easy care, low noise, volume is little, in light weight, cost is low takeup type 3 D stereo transformer.
The purpose of this utility model can reach by taking following measure: a kind of takeup type 3 D stereo transformer, comprise three single-phase iron cores, by hang top board and bottom plate that spiral shell defends to couple together, go up insulation pressing, insulation pressing, spiral shell are defended down, butterfly spring packing ring, nylon spiral shell are defended, coil windings, iron core is become by stem stem, iron yoke piece, and its design feature is:
A. iron core is that single-phase frame iron core, stem stem form, are mutually 60 ° of angles by the permeability magnetic material coiling of different in width, and the semicircle stem stem of each frame iron core and the semicircle stem stem of another frame iron core are combined into a circular columns; The upper and lower iron yoke of each frame iron core and the upper and lower iron yoke of another frame iron core are mutually 60 ° of angles, three stem stems, go up, each three totally six iron yokes form the 3-D solid structure of transformers;
B. stem stem is the multilayer-wound formula, being reeled through the private volume winding apparatus by permeability magnetic material forms, and all outward-dipping mobile certain distance of every volume one deck, the angle of inclination are 30 °, and forming every grade of iron core is a parallel hypotenuse tee section;
C. whole transformer body is defended and is connected and abut against top board and lower platen on the upper and lower iron yoke at the spiral shell that hangs that is mutually 120 ° on the tri-phase iron core post by three colligations, form basic load-bearing skeleton, the high and low pressure coil windings is connected the location respectively by upper and lower insulation pressing with top board, bottom plate fastening;
D. the high and low pressure coil windings is reeled on iron core column by special special-purpose coil winding machine and is formed.
The purpose of this utility model also can reach by taking following measure:
The first and last end reinforced insulation of coil windings, interior dress pressure switch, peripheral hardware expansion type gilled radiator, cover weldering dead oil case.
Coil windings be designed to the H class F insulation, interlayer and end all adopt the NOMEX insulating paper as insulation, adopt special process such as vacuum glue envelope, make environment-friendly and energy-efficient H grade insulation dry transformer.
Compared with prior art, the utlity model has following outstanding advantage:
1. three-phase magnetic circuit balance, waveform are good, energy-conservation, to economize material, easy care, low noise, volume little, in light weight, with low cost.
2. have good electrical and mechanical performance, higher thermal endurance class, can be suitable for various abominable running environment such as plateau and damp-heat area.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is a structure vertical view of the present utility model.
Fig. 3 is the structural representation of frame volume iron core of the present utility model.
Fig. 1, Fig. 2 and Fig. 3 constitute embodiment 1 of the present utility model.From Fig. 1, Fig. 2 as can be known, present embodiment is by three single-phase frame volume iron cores 8 that are mutually 60 ° of angles, defend 4 top boards that couple together 1 and bottom plate 5 by hanging spiral shell, last insulation pressing 10, following insulation pressing 11, spiral shell defends 2, butterfly spring packing ring 9, the nylon spiral shell defends 7, the pressure switch 12 of dress constitutes in coil windings 3 and the coil windings 3, wherein: frame iron core 8 is by stem stem, the iron yoke piece becomes, stem stem is the multilayer-wound formula, form through private volume winding apparatus coiling by permeability magnetic material, the all outward-dipping mobile certain distance of every volume one deck, the angle that tilts is 30 °, and forming every grade of iron core is a parallel hypotenuse tee section.
From Fig. 1, Fig. 2 as can be known: three spiral shells that hang that are mutually 120 ° are defended 4 connection top board 1 and bottom plates 5, form a solid firm foundations load-bearing skeleton; The other insulation pressing up and down 10,11 of each iron core column then respectively with top board 1 and bottom plate 5 by spiral shell defend 2, butterfly spring packing ring 9 and nylon spiral shell defend 7 and be fastenedly connected, and both clamped last lower yoke 8, compresses and fixed coil windings 3 again; Three iron core column are cylindrical, formed and hung spiral shell by several drawstrings with three and defend 4 and firmly be held together by six half of posts, cover whole winding winding 3, frame iron core 8 and transformer body and support each other, fastening mutually, and mainly still be carried on the basic skeleton one integrated mass.
As can be seen from Figure 3: the stem stem of frame volume iron core 8 is become the permeability magnetic material of different in width to reel on the equipment for coiling iron core of a special use to form by roller shear, every volume one deck is all outward-dipping 30 ° and move a certain distance when rolling, and forming every grade of iron core is parallel hypotenuse tee section shape.Under the situation of waste material not, the activity coefficient of iron core column is the highest like this, and this method for winding must be finished on the special tooling equipment.
Utilize this structure, all adopt the NOMEX insulation low the layer insulation and the end insulation of the coil of wire as insulation, can be made into and have good electric property and mechanical performance, higher thermal endurance class, can be applicable to the H class F insulation open type dry-type transformer of various abominable running environment such as plateau and damp-heat area, save expensive resin casting installation, belonged to the environment-friendly and energy-efficient product.
Take the strict technological measure of vacuum impregnating wet goods, can make 20 years not non-maintaining full-sealed transformers of suspended core.
