Abstract
The invention relates to an energy-saving transformer with a compact structure. The energy-saving transformer with a compact structure is characterized in that a main hollow path is composed of a strut curtain (6) and crepe paper (7), wherein the crepe paper (7) is higher than a winding (1) and extends out of two ends of the winding (1) respectively for 30-50mm; a cushion block (4) tightly presses the crepe paper (7) to form an angle ring; the cushion block (4) is provided with an upper clamping piece (3); distance between an upper yoke (2) and the end part of the winding (1) is 5mm; and the winding (1) is composed of a low-voltage winding (5) and a high-voltage winding (8). The energy-saving transformer with a compact structure has the beneficial effect that the structural space is fully utilized, the use ratio of the insulation material is improved, the section filling rate of an iron core is improved, the insulation collocation is improved, the insulation intensity is improved, local discharging amount is lowered, and the volume of the transformer is reduced. Especially, the structure is suitable for most types of oil immersed transformers, such as energy-saving products of S13, SH15 and the like, and the energy-saving transformer with a compact structure is favorable for utilization and popularization of novel energy-saving products.
Description
Technical field
The present invention relates to a kind of energy-economic transformer of tight structure.
Technical background
Conventional small distribution transformer coils structure mainly is cable paper now or puts gummed paper as layer insulation, main empty path employing corrugation or stay, and the end adopts cardboard end circle to add the core insulation structure.This structure insulation distance is big, but have wasting space and waste material cost shortcoming.
Summary of the invention
The energy-economic transformer that the purpose of this invention is to provide a kind of tight structure.
The technical scheme that the present invention is adopted for its technical problem of solution is:
A kind of energy-economic transformer of tight structure is characterized in that: main empty path is made up of stay curtain and crimped paper, and crimped paper is higher than winding; Stretch out each 30～50mm of winding two ends; Cushion block compresses crimped paper and forms square ring, and upper clamping piece is housed on the cushion block, and upper yoke is 5mm to the winding overhang distance.
Said winding is made up of low pressure winding and high pressure winding.
The invention has the beneficial effects as follows: make full use of structure space, improve the insulating material utilance, improve the core section filling rate, improve the insulation collocation, improve dielectric strength, reduce partial discharge quantity, dwindle volume of transformer.Particularly, this structure is applicable to oil-filled transformer overwhelming majority model, comprises energy-saving products such as S13 and SH15, helps the utilization and the popularization of energy saving product.
