The high-voltage and low-voltage winding rectangular coil not only is characterized by the impact resistance of a common cylindrical coil, but also reduces the coil layer voltage, reduces the local power generation, enlarges the cooling area of the coils, and effectively ensures the insulation distance between the high-voltage and the low-voltage coils of the amorphous alloy transformer.
Description
Technical field
The utility model relates to a kind of transformer square coil, particularly a kind of height gland around square coil.
Background technology
The loop construction of existing most power transformer products, all adopt traditional multi-layer cylinder formula coil, the structure that high-low pressure separates coiling, and the non-crystaline amorphous metal transformer is a square coil, guarantee the fail safe and the reliability of amorphous alloy transformer long-time running, the insulation distance between the high and low pressure coil just must guarantee.Because high-voltage coil and low-voltage coil is separately coiling, when suit, just be difficult to guarantee the insulation distance between the high and low pressure coil.Thereby the shortcoming that this loop construction exists is: 1, voltage between layers is excessive, and partial discharge quantity is big; 2, the insulation distance between high-voltage coil and low-voltage coil is difficult for guaranteeing.
Summary of the invention
In order to overcome the shortcoming of prior art, the purpose of this utility model provide a kind of height gland around square coil, this square coil can guarantee the insulation distance between high-voltage coil and low-voltage coil, reduces coil interlayer voltage, reduces partial discharge quantity.
The purpose of this utility model is achieved through the following technical solutions:
A kind of height gland around square coil, comprise profiled insulation tube, low-voltage coil and the high-tension coil suitable with transformer core, it is characterized in that: low-voltage coil is wound on the profiled insulation tube outside, be provided with the High-Voltage Insulation tube in the low-voltage coil outside, high-tension coil is wound on the High-Voltage Insulation tube outside.
After the low-voltage coil coiling described in the utility model through press-fiting, dipping lacquer and cured, coiling high-tension coil on low-voltage coil then.
Compared with prior art, the utility model not only has the shock-resistant characteristics of common cylindrical layer winding, and coil interlayer voltage is reduced, and reduces local energy output, increase the area of dissipation of coil, guaranteed the insulation distance between the amorphous alloy transformer high-voltage coil and low-voltage coil effectively.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
A kind of height gland described in the utility model around square coil, comprise the profiled insulation tube 1 suitable, low-voltage coil 2 and high-tension coil 3 with transformer core, low-voltage coil 2 is wound on profiled insulation tube 1 outside, be provided with High-Voltage Insulation tube 4 in low-voltage coil 2 outsides, high-tension coil 3 is wound on High-Voltage Insulation tube 4 outsides.
After low-voltage coil 2 coilings should through press-fiting, dipping lacquer and cured, coiling high-tension coil 3 on low-voltage coil 2 then.
Low-voltage coil 2 is multilayer subsection cylindrical formula, and is rectangular, and paper tinsel pile warp special equipment adopts the argon arc welding, has improved space availability ratio unshakable in one's determination, strengthens the anti-short circuit capability of product, eliminates helical angle, reduces axially loaded.Low-voltage coil 2 is wound on the polyester-imide profiled insulation tube 1, and through VPI technology dipping import C class F insulation lacquer, has improved coil mechanical strength and humidity resistance, and reduced partial discharge.
High-tension coil is multilayer subsection cylindrical formula, and is rectangular, and vertical many air passage structures adopt NOMEX paper bag anaerobic flat type copper wire to make conductor, make layer insulation with NOMEX paper, make overhang insulation with H level profiled insulation material, and air flue adopts H level I shape pulling part.Appearance holds multilayer NOMEX paper.After the whole oven dry of coil, cure curing molding through VPI vacuum power dipping, high temperature again; First and last section outsourcing insulation with the dielectric strength of intensifier coil end, improves impact resistance.High-tension coil directly overlaps on low-voltage coil, winding is supported on the independent winding system and is fixed during assembling, when being applied to amorphous alloy transformer, iron core is not stressed, when having reduced transformer short-circuit radially in contract and enlarge, thereby guaranteed the anti-short circuit capability of transformer effectively.
