Description
Technical field
The utility model relates to a kind of dry type axial direction double bundle transformer low-voltage coil structures.
Background technique
At home, dry type axial direction double bundle low-voltage coil generallys use the structure divided axially up and down, double division coils point
Coiling is carried out for upper and lower two independent parts, is then successively carrying out suit assembly, dry type axial direction double bundle product is generally answered
In the projects such as photovoltaic, wind-powered electricity generation, the case of installation site generally outdoors becomes or Ou Bianzhong, installation space are limited.If using
Traditional axial direction double bundle loop construction, two winding protruding heads of low pressure axial split are respectively in upper and lower two sides, then low pressure is drawn
The design of busbar to low pressure cabinet body will be more complicated out, increases the usage amount of secondary side outgoing line busbar, so the difficulty of installation
With the cost is relatively high.Therefore, in order to facilitate user installation needs, installation cost is reduced, by the coil of low pressure axial direction double bundle
Lead outlet row is all in top outlet, and the same side outlet；This makes a big difference with traditional structure, is not changing shape
Under the premise of, inventing the new structure of one kind becomes the primary study problem of structure of the invention.
Utility model content
The utility model improves the above problem, i.e., the technical problem to be solved by the present invention is to provide one kind
Dry type axial direction double bundle transformer low-voltage coil structure, it is easy for installation, and save human cost.
The specific embodiment of the utility model is: it is new that the utility model provides a kind of dry type axial direction double bundle low-voltage coil
Structure, including coil, the coil include the coil being located above, and are fixedly connected with lower coil below the coil, institute
State the coil lead being connected in coil by top outlet, be connected in the lower coil through coil and with it is online
Enclose the lower coil lead of lead same direction outlet.
Further, there is the axial air flue through coil and lower coil on the coil.
Further, pad is equipped with balance epoxy plate of the coil lead emission rate to height above the lower coil lead,
The epoxy plate is fixed in lower coil.
Further, insulating layer is fixedly connected between the coil and lower coil.
Compared with prior art, the utility model has the following beneficial effects: the utility model structure is simple, design is closed
Reason, installation convenience, not only effectively increases working efficiency, and time saving and energy saving, reduces human cost, has practicability.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1- coil, 2- coil, 3- lower coil, 4- coil lead, 5- lower coil lead, 6- axial direction gas
Road, 7- epoxy plate, 8- insulating layer.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Embodiment: as shown in Figure 1, in the present embodiment, the utility model provides a kind of dry type axial direction double bundle low-voltage line
New construction, including coil 1 are enclosed, the coil 1 includes the coil 2 being located above, and is fixedly connected with down below the coil 2
Coil 3 is connected with the coil lead 4 by top outlet in the coil 2, is connected in the lower coil 3 through upper
Coil 2 and lower coil lead 5 with the 4 same direction outlet of coil lead.
There is the axial air flue 6 through coil 2 and lower coil 3 in the present embodiment, on the coil 1, play ventilation and dissipate
The effect of heat.
In the present embodiment, pad is equipped with balance epoxy plate of the coil lead emission rate to height above the lower coil lead
7, the epoxy plate 7 is fixed in lower coil 3, to guarantee the width of each layer copper (aluminium) foil in coil 2 and lower coil 3 to ruler
It is very little in the same position.
In the present embodiment, the epoxy plate 7 can also be DMD preimpregnation material, F(H) support plate made of grade material etc..
In the present embodiment, it is fixedly connected with insulating layer 8 between the coil and lower coil, coil strength can be reinforced,
It is durable.
In the present embodiment, when work, the coil and lower coil of low pressure use the same mold, same same
Coiling is carried out simultaneously on foil coil winding machine, before coiling, coil lead outlet outgoing line position is arranged in upper end, lower coil
Lead outlet passes through coil, and lower coil lead is consistent with coil lead outlet direction, above, in coiling
Cheng Zhong, the coiling speed of control control copper (aluminium) foil, pays attention to carrying out correction processing to copper (aluminium) foil width direction, avoids product axis
Large error is generated to direction.The utility model structure is simple, improve axial direction double bundle low voltage winding in transformers installation and
Low-voltage lead assembly, improves production efficiency, and facilitates the installation of user scene bus, saves installation cost, designs rationally, tool
There is practicability.
