The winding insulating frame is applied to insulated isolation of high-tension and low-tension coils of the transformer and supporting and fixation of winding leads. The winding insulating frame comprises an insulating cylinder and a plurality of supporting strips. The supporting strips are provided with winding channels and distributed on the outer surface of the insulating cylinder. The supporting strips and the insulating cylinder are integrally formed. The winding insulating frame is high in mechanical strength, and good in insulation, heat dissipation and humidity resistance properties. Meanwhile, the winding insulating frame can be used without need of tedious assembly, is convenient to operate in a production process, and facilitates mechanized production.
Description
Technical field
The utility model relates to power equipment accessory field, more particularly, relates to a kind of transformer accessory.
Background technology
The winding insulation frame is applied in the dry-type transformer, is a kind of novel transformer accessory, is mainly used in the insulation isolation of transformer high-low-voltage coil and the support of winding conducting wire and fixes.The winding insulation frame has very important impact to mechanical strength, insulation property, heat radiation, the noise of transformer integral body.At present, generally use be with stay as the support of winding conducting wire, with round paper tube as the insulating part between the transformer high-low-voltage coil, namely existing winding insulation frame is to finish its function after adopting discrete round paper tube and stay assembling.Wherein, stay is generally formed by hardboard stay combination paper washer piece, also has minority enterprise to use the stay of integral type.The winding insulation frame is owing to adopting the mode of assembling parts, and its mechanical strength is low, and insulation property are poor, adopts the paper material that easily makes moist, and is having a strong impact on the performance of transformer.And the winding insulation frame needs assembling when using, and complex operation is unfavorable for mechanization production.Therefore, the winding insulation frame has very large room for improvement.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, the winding insulation frame that provide that a kind of mechanical strength is high, good insulation preformance, good heat dissipation, humidity resistance are good, is used for dry-type transformer.
In order to achieve the above object, the utility model is achieved by following technical proposals: a kind of winding insulation frame for dry-type transformer, it is characterized in that: comprise insulating cylinder and some stays, stay is provided with the coiling passage, stay is distributed on the outer surface of insulating cylinder, and stay and insulating cylinder are one-body molded.The one-body molded mechanical strength that improves the winding insulation frame of stay and insulating cylinder; The winding insulation frame need can not use through loaded down with trivial details assembling simultaneously, and is easy to operate in process of production, is convenient to mechanization production.
Described stay is comb shape, has broach, and forming between adjacent fingers can be by the coiling passage of winding conducting wire.
Preferred scheme is: the size of described coiling passage is suitable with the coiling wire gauge.Adjacent broach can be clamped coiling tightly, and the mechanical strength of transformer coil is improved greatly.
Described winding insulation frame refers to the winding insulation frame made by the polyester-imide material.The winding insulation frame mechanical strength of being made by the polyester-imide material is high, and good insulation preformance is corrosion-resistant, humidity.
Compared with prior art, the utlity model has following advantage and beneficial effect:
1, the stay of the utility model winding insulation frame and insulating cylinder are one-body molded, can improve the mechanical strength of winding insulation frame, and the winding insulation frame need can not use through loaded down with trivial details assembling simultaneously, and is easy to operate in process of production, is convenient to mechanization production;
2, the size of the coiling passage of the utility model winding insulation frame is suitable with the coiling wire gauge, and adjacent broach can be clamped coiling tightly, and the mechanical strength of transformer coil is improved greatly;
3, the utility model winding insulation frame is made by the polyester-imide material, and winding insulation frame not only mechanical strength is high, and good insulation preformance, can guarantee the dielectric strength between the high and low pressure coil; Simultaneously corrosion-resistant, humidity has overcome the shortcoming that the traditional round paper web easily makes moist and damages.
Description of drawings
Fig. 1 is the structural representation of the utility model winding insulation frame;
Fig. 2 is A section enlarged drawing among Fig. 1;
Wherein, 1 be insulating cylinder, 2 for the comb stays of transformer, 2.1 for broach, 2.2 for the coiling passage.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Embodiment
Winding insulation frame of the present utility model is applied to dry-type transformer, and its structural representation as shown in Figure 1.This winding insulation frame comprises insulating cylinder 1 and some stays 2.Wherein, stay 2 is comb shape, has broach 2.1, and 2.1 of adjacent fingers form coiling passage 2.2, and coiling is from coiling passage 2.2 processes.The size of coiling passage 2.2 is suitable with the coiling wire gauge, and adjacent fingers 2.1 can be clamped coiling tightly, and the mechanical strength of transformer coil is improved greatly.Stay 2 is evenly distributed on the outer surface of insulating cylinder 1.Insulating cylinder 1 and stay 2 are one-body molded, and such design has improved the mechanical strength of winding insulation frame, thereby make transformer integral body can bear larger pressure; The winding insulation frame need can not use through loaded down with trivial details assembling simultaneously, and is easy to operate in process of production, is convenient to mechanization production.
This winding insulation frame is made by the polyester-imide material.Not only mechanical strength is high for the winding insulation frame of being made by the polyester-imide material, and good insulation preformance, can guarantee the dielectric strength between the high and low pressure coil; Simultaneously corrosion-resistant, humidity has overcome the shortcoming that the traditional round paper web easily makes moist and damages.
Above-described embodiment is the better execution mode of the utility model; but execution mode of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection range of the present utility model.
