Abstract
The utility model relates to the technical field of power transformers and particularly discloses a high/low-voltage integral epoxy poured dry type power transformer. The high/low-voltage integral epoxy poured dry type power transformer comprises high/low-voltage coils, which are all poured together integrally by using epoxy resin. According to the utility model, by means of pouring the high/low-voltage coils together integrally by using the epoxy resin, the insulation among the high/low-voltage coils is single epoxy resin insulation, the distance of the epoxy resin only depends on the withstand voltage value of the epoxy resin, so that the size and mould number of the transformer can be reduced greatly, and meanwhile, the manufacture cost of the transformer is reduced.
Description
Technical field
The utility model relates to a kind of power transformer, specifically a kind of high-low voltage whole Power Transformers Operating Under Overload.
Background technology
The tradition Power Transformers Operating Under Overload is that high-voltage coil and low-voltage coil is poured into a mould respectively rear assembling, can cause like this volume of transformer coil larger, and number of molds is various.And traditional Power Transformers Operating Under Overload adopts air and epoxy resin mix insulation, high-tension coil inwall epoxy thickness is 3～4.5mm, reach 15kV/mm although epoxy resin is withstand voltage, but the air insulation distance must satisfy the electrical design requirement simultaneously, greater than 1mm/1kV, discharge otherwise can cause between the high-voltage coil and low-voltage coil.
The utility model content
The purpose of this utility model is to provide a kind of volume of transformer and high-low voltage whole Power Transformers Operating Under Overload of number of molds of reducing.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is as follows:
A kind of high-low voltage whole Power Transformers Operating Under Overload comprises high-voltage coil and low-voltage coil, and described high-voltage coil and low-voltage coil is cast in together with epoxy resin integral.
Epoxy thickness between the described high-voltage coil and low-voltage coil is 8 centimetres.
The utility model is by being cast in described high-voltage coil and low-voltage coil together with epoxy resin integral, so that insulation is single epoxy resins insulation between the high-voltage coil and low-voltage coil, the epoxy resin distance only depends on its withstand voltage, thereby can greatly reduce volume and the number of molds of transformer, also reduce the manufacturing cost of transformer simultaneously.
Description of drawings
Figure 1 shows that the schematic diagram of the whole epoxy casting of high-voltage coil and low-voltage coil that the utility model embodiment provides;
Figure 2 shows that the main TV structure schematic diagram of the high-low voltage whole Power Transformers Operating Under Overload that the utility model embodiment provides;
Figure 3 shows that the side-looking structural representation of Fig. 2.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
Referring to Fig. 1, the figure shows the whole epoxy casting structure of high-voltage coil and low-voltage coil of the dry-type power transformer that the utility model embodiment provides.For convenience of explanation, only show the part relevant with the utility model embodiment.
A kind of high-low voltage whole Power Transformers Operating Under Overload comprises high-tension coil 1, low-voltage coil 2, and described high-tension coil 1, low-voltage coil 2 usefulness epoxy resin 3 are together integrated poured.
More excellent, the epoxy thickness between the described high-voltage coil and low-voltage coil is 8 centimetres.
Shown in Fig. 2 ~ 3, the master who the figure shows the high-low voltage whole Power Transformers Operating Under Overload that the utility model embodiment provides looks and the side-looking structure.
Described high-tension coil 1 shown in Fig. 1, low-voltage coil 2 are cast in the coil 4 that forms together the dry-type power transformer shown in Fig. 2 ~ 3.
The utility model is by being cast in the whole epoxy of high-voltage coil and low-voltage coil together, so that insulation is single insulation resin between the high-voltage coil and low-voltage coil, the resin distance only depends on its withstand voltage, thereby can greatly reduce volume and the number of molds of transformer, also reduces the manufacturing cost of transformer simultaneously.
The utility model is safe and reliable, can reduce by 25% transformer manufacturing cost, reduces by 40% die cost.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
