Abstract
The utility model relates to a high-voltage coil type transformer comprising a support bar. The high-voltage coil type transformer is characterized in that one side of the support bar is wounded by a coil which at least forms coil cakes in four levels, including a first coil pancake, a second coil pancake, a third coil pancake and a fourth coil pancake from top to bottom. Meanwhile, angle rings are respectively arranged at two ends of each oil coil pancake. In addition, oil passages are respectively arranged on two sides of each coil pancake. Cushion blocks are respectively arranged in each oil passage. Therefore, by matching a narrow-side positive angle ring with a narrow-side negative angle ring, the whole high-voltage coil type transformer has no welding points and has reliable quality. Meanwhile, by using the U-shaped cushion blocks, the coil saves material compared with an inner shield type coil, has high filling coefficient and saves the work hour.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind of high-voltage line wound-type transformer.
Background technology
In the past in the design of transformer built-in electrical insulation, main, longitudinal insulation are considered respectively, so, the high-tension coil of 110kV level oil-filled transformer, all adopt the traditional structure of being entangled with formula continous way or inner shield continuous winding, invade the longitudinal insulation problem of Transformer Winding to solve shock wave.Its weak point is: interleaved coil, and solder joint is many, and reliability is poor, and man-hour is big; Internally shielded coil, many with material, the insulation of shielding conductor is thick, when wrapping is taken a lot of work.
The utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of high-voltage line wound-type transformer is provided.
For realizing the purpose of this utility model high-voltage line wound-type transformer, include support bar, wherein: described support bar one side is arranged with coil, and coil constitutes the coil cake of four levels at least, has both comprised the first coil cake, the second coil cake, tertiary coil cake, the 4th coil cake from top to bottom; Described coil cake two ends are provided with square ring; Described coil cake both sides are arranged with oil duct, are provided with cushion block in the oil duct.
Further, above-mentioned high-voltage line wound-type transformer, wherein, described square ring includes positive square ring in narrow limit and narrow limit dihedral ring, and the positive square ring in described narrow limit is distributed in coil cake inboard, and described narrow limit dihedral ring is distributed in the coil cake outside.
Further, above-mentioned high-voltage line wound-type transformer wherein, is filled with insulating board between positive square ring in described narrow limit and the narrow limit dihedral ring.
Again further, above-mentioned high-voltage line wound-type transformer, wherein, described cushion block is a U type cushion block, in its oil duct that is located in the first coil cake both sides that distributes respectively and in the oil duct of tertiary coil cake both sides.
Adopt technical solutions of the utility model, compared with its good manufacturability of traditional interleaved coil, coiling is saved over half man-hour.And by the cooperation of positive square ring in narrow limit and narrow limit dihedral ring, entire product does not have solder joint, reliable in quality.Simultaneously, by the use of U type cushion block, economize with material than internally shielded coil, the coefficient height of filling a vacancy is saved man-hour.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the organigram of high-voltage line wound-type transformer.
The implication of each Reference numeral is as follows among the figure:
1 support bar, 2 first coil cakes
3 second coil cakes, 4 tertiary coil cakes
5 the 4th coil cakes, 6 oil ducts
The positive square ring 8 narrow limit dihedral rings in 7 narrow limits
9 insulating board 10U type cushion blocks
Embodiment
High-voltage line wound-type transformer as shown in Figure 1, include support bar 1, its unusual part is: be arranged with coil in support bar 1 one sides, and coil constitutes the coil cake of four levels at least, has both comprised the first coil cake 2, the second coil cake 3, tertiary coil cake 4, the 4th coil cake 5 from top to bottom.Simultaneously, be provided with square ring at coil cake two ends.And, be arranged with oil duct 6 in coil cake both sides, be provided with cushion block in the oil duct 6.
In conjunction with the utility model one preferred implementation, stop well cuts to form " foot bridge ", the described square ring that adopts includes positive square ring 7 in narrow limit and narrow limit dihedral ring 8, and the positive square ring 7 in described narrow limit is distributed in coil cake inboard, and described narrow limit dihedral ring 8 is distributed in the coil cake outside.Simultaneously, in order further to consolidate effect, between positive square ring 7 in narrow limit and narrow limit dihedral ring 8, be filled with insulating board 9.
Further, form " foot bridge ", and prevent that effectively " foot bridge " contact with electrode and constitute path, frequency breakdown voltage is significantly improved, make to puncture the obvious minimizing of dispersiveness in order better to stop well cuts.The cushion block that the utility model adopts is a U type cushion block 10, in its oil duct 6 that is located in the first coil cake, 2 both sides that distributes respectively and in the oil duct 6 of tertiary coil cake 4 both sides.Like this, bear certain voltage, cooperate the use of U type cushion block 10, improved oil clearance voltage and distributed, the end field intensity is descended, improved the ability that coil bears compound field intensity by positive square ring 7 in narrow limit and narrow limit dihedral ring 8.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, behind employing the utility model, compared with its good manufacturability of traditional interleaved coil, coiling is saved over half man-hour.And by the cooperation of positive square ring in narrow limit and narrow limit dihedral ring, entire product does not have solder joint, reliable in quality.Simultaneously, by the use of U type cushion block, economize with material than internally shielded coil, the coefficient height of filling a vacancy is saved man-hour.
Certainly, more than only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
