Abstract
The utility model discloses a pie type resin-cast high-voltage coil structure, and belongs to the technical field of transformers. The pie type resin-cast high-voltage coil structure comprises a high-voltage lead, coil end insulation portions, a coil outer insulation portion and a coil inner insulation portion, wherein the high-voltage lead is provided with a plurality of coil outlet ends, the coil end insulation portions are arranged at the two ends of the high-voltage lead respectively, and the coil outer insulation portion and the coil inner insulation portion are arranged on the two sides of the high-voltage lead respectively. The pie type resin-cast high-voltage coil structure is characterized in that the high-voltage lead is composed of two secondary high-voltage leads, the high-voltage lead is of a pie structure, and section insulation portions are arranged between the two secondary high-voltage leads. According to the technical scheme, the pie type resin-cast high-voltage coil structure is compact overall, the effective space of a coil is made full use of, the filling rate of the coil is increased, consumption of insulating materials is reduced, and the cost of the transformers is effectively reduced.
Description
Technical field
The utility model belongs to transformer technology field, particularly relates to a kind of cake formula resin-poured high-voltage coil structure.
Background technology
6kV, the 10kV pouring dry transformer in industry, produced at present, high-tension coil generally has two kinds of versions, and one is that band interlayer insulated wire is around layered structure; One is that band layer insulation paper tinsel is around layered structure.As shown in Figure 1: a kind of typical conventional high-tension loop construction is: it comprises and is provided with insulation 7 in the high-voltage conducting wires 4 of multiple winding protruding heads 1, the coil-end insulation 6 that is arranged at high-voltage conducting wires 1 two ends, the coil external insulation 5 that is arranged at high-voltage conducting wires both sides and coil; High-voltage conducting wires 4, by four sections of (can be also multistage, this be selected as the case may be) sub-high-voltage conducting wires compositions, is provided with section insulation 3 between four cross-talk high-voltage conducting wires.Every cross-talk high-voltage conducting wires is made up of the sub-high-voltage conducting wires of multilayer, between adjacent straton high-voltage conducting wires, is provided with layer insulation 2; Find by practice, there is following defect in the high-tension coil of this traditional structure: because this high-tension coil in structure exists larger intersegmental distance, therefore cause to a certain extent the effective filling rate of coil lower, caused the increase of insulating material consumption, cost to increase.
Utility model content
The technical problems to be solved in the utility model is: the cake formula resin-poured high-voltage coil that a kind of coefficient of safety is good, welding efficiency is high, welding quality is good structure is provided.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
A kind of cake formula resin-poured high-voltage coil structure, comprise be provided with multiple winding protruding heads high-voltage conducting wires, be arranged at the coil-end insulation at high-voltage conducting wires two ends and be arranged at the coil external insulation of high-voltage conducting wires both sides and coil in insulation; Described high-voltage conducting wires is made up of two cross-talk high-voltage conducting wires, and described high-voltage conducting wires is cake formula structure; Between two cross-talk high-voltage conducting wires, be provided with section insulation.
Advantage and the good effect that the utlity model has are: by adopting technique scheme, high-voltage coil structure entirety of the present utility model is compacter, makes full use of the useful space of coil, has increased the filling rate of coil, reduce the use amount of insulating material, effectively reduced transformer cost.

Fig. 1 is the traditional structure schematic diagram of high-tension coil;
Fig. 2 is structural representation of the present utility model.
Wherein: 1, winding protruding head, 2, layer insulation, 3, section insulation, 4, high-voltage conducting wires, 5, coil external insulation, 6, coil-end insulation, 7, insulation in coil.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 2, a kind of cake formula resin-poured high-voltage coil structure, comprise and be provided with insulation 7 in the high-voltage conducting wires 4 of multiple winding protruding heads 1, the coil-end insulation 6 that is arranged at high-voltage conducting wires 4 two ends, the coil external insulation 5 that is arranged at high-voltage conducting wires 4 both sides and coil, in coil, insulation 7 is around on mould; High-voltage conducting wires 4 is made up of two cross-talk high-voltage conducting wires, and high-voltage conducting wires 1 is cake formula winding structure; Between two cross-talk high-voltage conducting wires, be provided with section insulation 3.By adopting technique scheme, the utility model has effectively utilized the useful space of high-tension coil, has greatly increased the filling rate of coil, reduces the use amount of insulating material.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
