The wire, the cross section of which is flat, is wound with the relatively narrow side as a supporting side; insulating filler is arranged between wire turns; an insulating band is wound around the wound coil; and besides, the coil is dipped with insulating lacquer with a high heat-resistant class. The utility model can thoroughly eliminate the short circuit among the turns and layers of the drawn coil of the choke transformer, reduce the unbalance factor and enhance the heat-resistant and voltage-resistant class, moreover, under the condition of the same capacity, the volume of the choke transformer is reduced, and thereby, the production cost is saved to the max.
Description
Technical field
The utility model relates to the railway signal choke transformer, particularly a kind of vertical winding type railway signal choking-winding.
Background technology
In electric railway, choke transformer has the backflow and the balance locomotive traction function of current, and while and the track circuit that send electric equipment and power receiving equipment to constitute various standards are as 25Hz track circuit, half wave track circuit and audio frequency track circuit etc.
The choking-winding of existing choke transformer uses the dual-fiberglass wrapped flat copper wire of all size to be material, its production technology mostly is " flat around " mode greatly, be about to flat horizontal surface (the being wide face) beginning of flat type copper wire, be close on the specific loose tool and twine, then choking-winding is carried out shaping, to reach the dimensional requirement of installation.
There is following deficiency in this production technology:
(1) owing to needs through-flow hundreds of amperes electric current on the choke transformer choking-winding, for guaranteeing the requirement of current density, the cross-sectional area of the flat type copper wire of its use is bigger, certainly will use bigger crooked dynamics when twining choking-winding, so when twining second layer choking-winding, rub between two-layer choking-winding, may damage the insulating barrier of flat type copper wire outside, cause short circuit phenomenon;
(2) after shaping was finished in the choking-winding coiling, often profile was irregular, is not easy to stack up and down;
(3) because choking-winding is a double-decker, be unfavorable for that the lead heat distributes;
(4) the employed dual-fiberglass wrapped flat copper wire of choking-winding is after long-time the use, and its insulating barrier is aging easily, can cause the coil short phenomenon, makes track circuit failure, disturbs normally driving.
The utility model content
The utility model has overcome above-mentioned shortcoming, and a kind of vertical winding type railway signal choking-winding of simple in structure, stable performance is provided.
The technical scheme in the invention for solving the technical problem is: a kind of vertical winding type railway signal choking-winding, form by the lead coiling, the cross section of described lead is a flat, with narrower one side is the supporting surface coiling, be provided with insulation filler between described conductor turns, the coil periphery after the coiling also is wound with insulating tape.
Described insulating tape also can be impregnated with the insulation enamelled coating outward.
Described lead can adopt flat type copper wire.
Described insulation filler can adopt high temperature resistant, corrosion-resistant, wear-resisting insulating material.
Described insulating tape can adopt high insulation, wear-resisting, corrosion resistant ribbon.
The utility model can thoroughly be eliminated choke transformer hauling-eye turn-to-turn, layer short circuit; Reduce unbalanced coefficient, strengthen heat-resisting, voltage withstand class, and under the same capability condition, dwindle the choke transformer volume, save production cost to a great extent.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
As Fig. 1, shown in 2, the structural representation of choke transformer choking-winding, adopting the flat type copper wire 4 of naked layer is lead, leptoprosopy with flat type copper wire 4 is a supporting surface, adopt upright around mode, be close on the specific loose tool and turn to multiturn, form the spring shape, and between every circle lead, fill high temperature resistant, corrosion-resistant, wear-resisting insulating material is as turn-to-turn insulation filler 3, use high temperature resistant then, corrosion-resistant, wear-resisting banded twister, promptly insulating tape 2 is with its winding, typing, and dry after flooding the high insulating varnish of thermal endurance class, last sealing wire nose 1, shaping is installed and is formed.
The utility model can reduce the use length of flat type copper wire, reduce the height of choking-winding, thereby reduce the effective resistance of choke transformer choking-winding, improve the quality factor of choke transformer, make full use of the window unshakable in one's determination that choke transformer uses, but also can effectively reduce requirement, reduce the requirement of choke transformer window height unshakable in one's determination to window height unshakable in one's determination, can effectively reduce the volume of choke transformer, save production cost.
Described choking-winding turns to spring-like, forms single layer structure, increases the lead area of dissipation, helps heat and distributes, and thoroughly solve the problem that original mode of production is prone to layer short circuit.
And between every circle lead, reliably insert the insulation filler that high temperature resistant, corrosion-resistant, wear-resisting insulating material is made, increase the turn-to-turn insulation degree of choking-winding, can make transformer when lead satisfies current density and requires, can reliable and stable operation under hot conditions; And the high reliability of insulating material between lead, increase useful life of choke transformer.
Described coil outside is twined by height insulation, wear-resisting, corrosion resistant strip insulation band, and the high insulating varnish of dipping thermal endurance class, improves choke transformer dielectric voltage withstand grade.
Two choking-windings are installed in a choke transformer usually, adopt two choking-windings of the present utility model except that the wire length difference, all the other are all identical, owing to be spring shape during coiling, therefore when two choking-windings stack up and down, the ledge of just in time the same coil of the ledge lower end of lower coil upper end is staggered staggered relatively, be combined into a circle, not only be convenient to stack up and down, and guarantee the equal turn numbers of its cutting magnetic line, the magnetic line of force quantity of two choking-winding cuttings is more close, thereby has reduced the unbalanced coefficient of choke transformer.And under choking-winding number of turn same case, the height that adopts the utility model choking-winding can reduce window height unshakable in one's determination significantly also much smaller than the choking-winding height of prior art, saves production cost.
More than vertical winding type railway signal provided by the utility model is described in detail with choking-winding, used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
