Description
Technical field
The utility model relates to power transformer, relates in particular to the amorphous alloy dry-type transformer that a kind of high-tension coil is cake formula.
Background technology
Amorphous alloy dry-type transformer has very large advantage on energy-saving and environmental protection, economical operation, the dry-type transformer that is mainly the comparable silicon steel plate core manufacture of no-load loss is low by 60%～70%, and operating cost is low, comprehensive benefit is good, in electric power system, is widely applied very soon.Due to the property of amorphous alloy material, the iron core of transformer is generally rectangle, and the high-tension coil now using on this transformer is segmentation multi-layer cylinder formula coil, and its interlayer insulating film is thicker, and activity coefficient is low, makes manufacturing cost higher.
Utility model content
The technical problems to be solved in the utility model is: a kind of amorphous alloy dry-type transformer of saving material is provided.
In order to address the above problem, it is the amorphous alloy dry-type transformer of cake formula that the utility model provides a kind of high-tension coil, comprise non-crystaline amorphous metal rectangle iron core, insulation framework and be enclosed within the height on rectangle iron core, low-voltage coil, described high-tension coil is rectangle disc coil, low-voltage coil is foil coil, main empty path between high-tension coil and low-voltage coil is 34～35mm, high-tension coil consists of positive cake and anti-cake alternative arrangement, positive cake and anti-cake are formed by strip conductor continuous coiling, the turn-to-turn of described high-tension coil and the thickness of insulating layer between cake are 0.3mm ~ 0.4mm, this high-tension coil is poured into a mould through epoxide resin vacuum.
Adopt dry-type transformer advantage of the present utility model: the turn-to-turn of high-tension coil and the thickness of insulating layer between cake are 0.3mm ~ 0.4mm, the activity coefficient of high-tension coil is greatly improved, and calculate by field intensity, partial discharge quantity between turn-to-turn and cake is all less than 5PC, secondly when manufacturing wire, no longer need to arrange respectively between turn-to-turn insulation and cake and insulate, as long as be wound around insulating barrier on strip conductor, when winding the line like this, just can disposablely complete the setting of two kinds of insulation.
As preferred version, between first and last end four cakes of described high-tension coil, be added with the thick DMD insulation of 0.2mm, its objective is in order to improve the impact-level of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of dry-type transformer of the present utility model;
1: rectangle iron core; 2: low-voltage coil; 3: main empty path; 4: high-tension coil; 5: strip conductor; 6: epoxy resin.
Embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated,
According to Figure 1 shows that a kind of high-tension coil of the present utility model is the amorphous alloy dry-type transformer of cake formula, comprise the rectangle iron core 1 of non-crystaline amorphous metal and be enclosed within the high and low pressure coil on iron core 1, described high-tension coil 3 is rectangle disc coil, low-voltage coil 2 is foil coil, 2 main empty paths that 34.5mm is set of high-tension coil 3 and low-voltage coil, high-tension coil 3 consists of positive cake and anti-cake alternative arrangement, positive cake and anti-cake are formed by strip conductor 5 continuous coilings, and the turn-to-turn of high-tension coil 3 and the thickness of insulating layer between cake are 0.3mm ~ 0.4mm; This high-tension coil 3 is through epoxy resin 6 vacuum pourings.
The turn-to-turn of high-tension coil 3 and the thickness of insulating layer between cake are 0.4mm, the activity coefficient of high-tension coil 3 is greatly improved, and calculate by field intensity, the partial discharge quantity of product is all less than 5PC, secondly wait not need to arrange respectively between turn-to-turn insulation and cake during fabrication and insulate, as long as be wound around insulating material by field intensity requirement on strip conductor 5, in the time of coiling, just can disposablely complete the setting of two kinds of insulation.
Insulating barrier between each four cakes of the first and last end of high-tension coil 3 arranges the thick DMD insulating material of 0.2mm, its objective is in order to improve the impact-level of product.
Described DMD insulating material refers to: by one deck polyester film, be coated with adhesive, two sides is a kind of composite insulating material goods that nonwoven polyester fabric is compound, calendering forms; There is good mechanical strength, dielectric property and higher electric durability energy.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
