Abstract
The utility model relates to a three-phase transformer comprising three single-phase transformers. Each single-phase transformer comprises an iron core, a magnetic circuit and a winding. The three single-phase transformers are arranged side by side and mounted on a fixing support through bolts, and at least one layer of insulation epoxy plate is arranged in the middle of each transformer winding. The three-phase transformer is simple in structure, high in insulation grade, convenient to manufacture and safe to use, iron loss and copper loss due to temperature rise of the transformer are effectively reduced, and operational reliability of the transformer is improved.
Description
Technical field
It is a kind of three-phase transformer that the utility model relates to.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core.Transformer is divided into single-phase transformer and three-phase transformer by the number of phases, existing three-phase transformer complex structure, and volume is large, the heat radiation difficulty, loss is large, and efficiency is low, and because the class of insulation to it is had relatively high expectations, traditional insulating material result of use is not ideal enough.
The utility model content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide the three-phase transformer that a kind of efficiency is high, the class of insulation is high.
The utility model solves the technical scheme that its technical problem adopts: a kind of three-phase transformer, comprise three single-phase transformers, each single-phase transformer has iron core, magnetic circuit and winding, described three single-phase transformers are placed side by side and be arranged on fixed mount the middle at least one deck insulating epoxy plate that is provided with of each Transformer Winding by screw.
Further, described winding upper end is provided with the inlet wire head, and described winding lower end is provided with terminal.
Further, the quantity of described insulating epoxy plate is three layers.
The beneficial effects of the utility model are, three-phase transformer of the present utility model is simple in structure, and the class of insulation is high, have effectively slowed down iron loss and copper loss that the temperature rise due to transformer causes, easily manufactured, have improved the operational reliability of transformer, use safety.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. iron cores in figure, 2. winding, 3. inlet wire head, 4. terminal, 5. insulating epoxy plate.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Three-phase transformer as shown in Figure 1, comprise three single-phase transformers, each single-phase transformer has iron core 1, magnetic circuit and winding 2, three single-phase transformers are placed side by side and be arranged on fixed mount by screw, be provided with at least one deck insulating epoxy plate 5 in the middle of each Transformer Winding, improved the class of insulation of transformer.The winding upper end is provided with inlet wire head 3, and the winding lower end is provided with terminal 4.Wherein, the quantity of insulating epoxy plate 5 is three layers.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, the relevant staff can, in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to the claim scope.
