Abstract
The utility model discloses an opened coiled iron core oil-immersed transformer including an oil tank, an iron core, and a coil. A tank cover is arranged on the oil tank, the iron core and the coil are arranged in the oil tank, and the transformer is characterized in that the iron core is a three-phase and five-column one and is combined through the side by side arrangement of four mouth-shaped single-phase opened coiled iron cores having a semi-rectangular cross section, the cross sections of the five columns of the iron core are rectangular opened coiled iron cores, two fractures are arranged in each layer and are arranged at two edge columns, low-voltage coils are arranged in the five columns of the iron core, an insulation layer is fastened outside the low-voltage coils, and high-voltage coils are arranged outside the insulation layer, an upper clamping member and a lower clamping member are fixed on the iron core and lead out a high-voltage terminal and a low-voltage terminal. The transformer provided has the characteristics of shorter magnetic circuit, high power factor, small size, high emergency short circuit resistance capability, and good technological condition.
Description
Technical field
The utility model relates to transformer manufacture technology, particularly relates to a kind of hatch coiled iron core oil-immersed type transformer.
Background technology
Oil-filled transformer is mainly comprised of iron core, coil and fuel tank, and the iron core major part of at present domestic oil-filled transformer is laminated structure, by silicon steel sheet stack, is formed.Because the iron core of stack moulding all exists many places mitre in junction, every layer of limit, and cause the increase of magnetic resistance and iron loss, the exciting current of transformer is also increased, reduced power factor, had a strong impact on the power supply quality of electrical network.Transformer core seam has also caused the problem that running noises is large.In order to overcome the defect of above-mentioned laminated core structure, recent year has many producers to adopt coiled iron core transformer, this transformer core is that the silicon strip continuous reeling by definite shape forms, and transformer performance has a certain upgrade, and is mainly reflected in that no-load loss is low, noise is little.But because coiled iron core is jointless structure, also there are problems, as: manufacturing equipment production capacity is limited, needs special-purpose spooling equipment during transformer coil coiling, and wind the line with iron core, winding process is difficult, complicated, production efficiency is low.Especially cannot solve big-and-middle-sized transformer coiling and paint-dipping process.Maintenance aspect is very difficult especially, once transformer coil breaks down, just cannot take off coil from iron core and change, and must cause scrapping of whole transformer.Owing to there is above-mentioned shortcoming, popularization and use without seam volume iron core have been restricted.
Utility model content
The purpose of this utility model is exactly defect and the deficiency existing for overcoming above-mentioned prior art, and a kind of hatch coiled iron core oil-immersed type transformer is provided.
The technical scheme adopting is:
A kind of hatch coiled iron core oil-immersed type transformer, comprise fuel tank, iron core, on fuel tank, be equiped with case lid, bushing and low-tension bushing are housed on case lid, 0 phase sleeve pipe, oil level indicator, exhaust apparatus, shunting switch, four groups of fin are distributed on four sides, iron core and coil are arranged in fuel tank, it is characterized in that described iron core is three-phase and five-pole iron core, the single-phase open core that is half rectangle for its cross section of " mouth " font by four face shapings is arranged side by side and combines, the cross sectional shape of five stem stems of iron core is rectangular aperture volume iron core, in every layer, there are two fractures, fracture site is located at two side columns, in five stem stems of iron core, be incorporated with coil.
The utlity model has the good characteristics such as magnetic circuit is shorter, power factor is higher, volume is less, the ability of anti-sudden short circuit is strong, process conditions are good.The spooling equipment that does not need special-purpose volume iron core special use in manufacturing process, coil coiling separately, has improved production efficiency.Once transformer in use coil breaks down, transformer core opening part can be opened, then take out coil and keep in repair and change, fundamentally solved volume iron core due to the problems that produce without seam.
