Abstract
The invention relates to a transformer with oil ducts, which comprises a transformer body and is characterized in that a continuous winding device is arranged in the transformer body; interval convex strips are distributed on the continuous winding device; and oil duct accommodating grooves are formed between the interval convex strips. Therefore, a conventional thinking model is broken through and big and small oil ducts at both end parts of a coil are distributed in an overlapped mode, so that the structural size of the transformer is reduced. Continuous air ducts between cakes are properly reduced, the voltage is uniformly distributed and the electric potential gradient is reduced. Moreover, the transformer accords with the small oil clearance volume principle. Meanwhile, a composite field intensity concept is provided, the used material is reduced and the cost is lowered. More importantly, the loss is reduced, so that the efficiency of the transformer is improved and the transformer is beneficial for saving energy.
Description
Technical field
The present invention relates to a kind of transformer, relate in particular to a kind of transformer that has oil duct.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).In electric equipment and radio-circuit, up-down voltage, the matched impedance done commonly used, safety isolation etc.In generator, no matter be that coil movement is passed through magnetic field or Movement in Magnetic Field through fixed coil, all can be in coil induced potential, these two kinds of situation, the value of magnetic flux is all constant, but with the magnetic flux quantity of coil intersecting chain change is arranged, this is the principle of mutual induction.Transformer is exactly that a kind of undesirable mutual electromagnetic inductance of utilizing is answered voltage of transformation, the device of electric current and impedance.The function of transformer mainly contains: voltage transformation; Current transformation, impedance conversion; Isolate; Voltage stabilizing (magnetic saturation transformer) etc.
Traditional transformer all adopts with oil duct between large flat bread increases electrical strength, and its weak point is following: because oil duct strengthens, do not consider that electric capacity reduces between cake, voltage skewness, the unfavorable factor that electric potential gradient strengthens.Simultaneously, the high size of transformer window is increased, materials increase, and cost improves.And the no-load loss of transformer and load loss increase, and are unfavorable for energy-conservation.
Summary of the invention
The object of the invention is exactly the problems referred to above that exist in the prior art in order to solve, and a kind of transformer that has oil duct is provided.
The object of the invention is realized through following technical scheme:
A kind of transformer that has oil duct includes the transformer body, wherein: be provided with the continous way winding arrangement in the described transformer body, be distributed with raised line at interval on the described continous way winding arrangement, form the oil duct holding tank between the raised line of described interval.
Further, above-mentioned a kind of transformer that has oil duct, wherein: the total distance between the raised line of described interval is 210-220mm.
Further, above-mentioned a kind of transformer that has oil duct, wherein: the total distance between the raised line of described interval is 217mm.
Again further, above-mentioned a kind of transformer that has oil duct, wherein: non-range distribution between the raised line of described interval, big or small oil duct overlapping formula does not equidistantly distribute between the raised line of in other words described interval.
The advantage of technical scheme of the present invention is mainly reflected in: break through traditional thoughtcast, coil both ends large and small oil duct overlapping formula distributes, and the physical dimension of transformer is reduced.Suitably reduce oil duct between the continous way cake, surge voltage is evenly distributed, and electric potential gradient reduces.And, meet the small oil gap volume theory.Simultaneously, propose compound field intensity notion, materials reduce, and reduce cost.What is more important reduces loss transformer efficiency is improved, and helps energy-conservation.
Description of drawings
The object of the invention, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical scheme of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of requirement protection of the present invention.In the middle of these accompanying drawings,
Fig. 1 is the organigram of continous way winding arrangement.
Embodiment
A kind of transformer that has oil duct as shown in Figure 1 includes the transformer body, and its unusual part is: be provided with continous way winding arrangement 1 in the transformer body that the present invention adopted.Specifically, on continous way winding arrangement 1, be distributed with raised line 2 at interval, order forms oil duct holding tank 3 at interval between the raised line 2 thus.
With regard to the present invention's one preferred implementation, the total distance between the raised line 2 is 210-220mm at interval.Certainly, in order to realize the effect of little oil duct, the puncture of unit distance oil is improved, increase the dielectric strength of transformer, the total distance between the interval raised line 2 that the present invention adopts is reduced to 217mm.
Further, in order helping to increase electric capacity between cake, the starting voltage of lightning impulse voltage on the continuous winding length direction to be distributed be tending towards evenly, electric potential gradient reduces, at interval non-equidistantly distributing between the raised line 2.Simultaneously, the degree of depth of oil duct holding tank 3 is consistent.
Be used for seeing in conjunction with actual making of the present invention. break through traditional thoughtcast, electric capacity makes the starting voltage distribution of lightning impulse voltage on the continuous winding length direction be tending towards even, the electric potential gradient minimizing to oil duct between cake to increase between the suitable minimizing of employing cake.And, according to the small oil gap volume theory, the breakdown strength of oil, varying stress oil volume more hour, the breakdown strength of oil is higher, suitably reduces oil duct between cake, and the puncture of unit distance oil is improved, and increases the dielectric strength of transformer.Simultaneously, always separated consideration to main insulation and longitudinal insulation in the past, and do not meet actual working state, its truth is two different functions of time with field intensity radially axially, should be with synchronization on the oscillogram, and the value of same point superposes, and asks its compound field intensity.
Can find out through above-mentioned character express, behind employing the present invention, break through traditional thoughtcast, the physical dimension of transformer is reduced.Suitably reduce oil duct between the continous way cake, voltage is evenly distributed, and electric potential gradient reduces.And, meet the small oil gap volume theory.Simultaneously, propose compound field intensity notion, materials reduce, and reduce cost.What is more important reduces loss transformer efficiency is improved, and helps energy-conservation.
