Description
Technical field
The application relates to field transformer, especially a kind of transformer.
Background technology
The places such as dry-type transformer just refers to that iron core and winding are not immersed in the transformer in insulating oil, is widely used in localized lighting, skyscraper, airport at present, harbour CNC plant equipment.
For meeting the needs of network system, dry-type transformer has multiple electric pressure usually, by the adjustment to electric pressure, thus makes it be applicable to different needs.As the Chinese patent that patent announcement number is " CN202373438U ", it changes the connection between binding post, to realize the conversion of electric pressure by connecting rod.But voltage is unstable often, and when voltage fluctuation, we need regulation voltage among a small circle, and prior art does not also have the design that can adjust voltage among a small circle.
Summary of the invention
The application provides a kind of transformer, and solving prior art cannot the problem of regulation voltage among a small circle.
A kind of transformer, comprise transformer shell, transformer shell surface is provided with the pressure regulation panel for adjusting electric pressure, pressure regulation panel is provided with some pressure regulation terminals and the connecting rod for being connected pressure regulation terminal, also comprise the fine setting panel being arranged on transformer shell surface, fine setting panel is used for the voltage adjusting transformer in low voltage range.
Preferably, pressure regulation panel is positioned at the first side of transformer shell, and fine setting panel is positioned at the second side of transformer shell.
Preferably, pressure regulation panel is positioned at the high-pressure side of transformer shell, and fine setting panel is positioned at the low-pressure side of transformer shell.
Preferably, fine setting panel is provided with some binding posts, and binding post is connected with alihnment coil leading-out terminal, and the magnitude of voltage that alihnment coil leading-out terminal can change is in low voltage range.
Preferably, binding post is provided with 12, and 12 binding posts are used for being divided into by transformer 5 to finely tune grade.
The beneficial effect of the application is, the application comprises transformer shell, transformer shell surface is provided with the pressure regulation panel for adjusting electric pressure, pressure regulation panel is provided with some pressure regulation terminals and the connecting rod for being connected pressure regulation terminal, also comprise the fine setting panel being arranged on transformer shell surface, fine setting panel is used for the voltage adjusting transformer in low voltage range.Because the application is also provided with fine setting panel, thus itself can among a small circle regulation voltage.

Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
Embodiment 1:
A kind of transformer, as depicted in figs. 1 and 2, comprises transformer shell 11, is provided with transformer core 12 in transformer shell 11, iron core 12 is arranged with coil.Transformer shell 11 surface is provided with the pressure regulation panel 2 for adjusting electric pressure, and pressure regulation panel 2 is provided with some pressure regulation terminals 21 and the connecting rod 4 for being connected pressure regulation terminal 21.Also comprise the fine setting panel 3 being arranged on transformer shell 11 surface, fine setting panel 3 for adjusting the voltage of transformer in low voltage range, here low pressure range refers to universally recognized voltage range in the electric power system of this area, generally about 5 percent of rated voltage, but be not limited thereto, those skilled in the art should know.Fine setting panel 3 just for making the changes values of transformer in low voltage range, thus realizes regulation voltage among a small circle.
Embodiment 2:
As the improvement of embodiment 1, pressure regulation panel 2 is positioned at the first side of transformer shell 11, and fine setting panel 3 is positioned at the second side of transformer shell 11.Transformer shell 11 is generally Long Circle or circular configuration, and thus pressure regulation panel 2 and fine setting panel 3 are positioned at the Different Diameter of transformer shell 11 upwards.If fine setting panel 3 and pressure regulation panel 2 are positioned at the same side, the leading-out terminal of coil can affect each other, causes operation inconvenience.So fine setting panel 3 is done separately on one panel.
Further, pressure regulation panel 2 is positioned at the high-pressure side of transformer shell 11, and fine setting panel 3 is positioned at the low-pressure side of transformer shell 11.Transformer core 12 has high-pressure side and low-pressure side, the high-pressure side of transformer shell 11 refer to the high-pressure side of transformer core 12 relative to that side, same, the low-pressure side of transformer shell 11 refer to the low-pressure side of transformer core 12 relative to that side.
As shown in Figure 3, fine setting panel 3 is provided with several binding posts 31, and binding post 31 is connected with alihnment coil leading-out terminal, and alihnment coil leading-out terminal is drawn from coil, is connected on binding post 31.Voltage-regulation principle due to transformer is the change by coil turn, thus the corresponding multiple coil turn of alihnment coil leading-out terminal, and arranges magnitude of voltage that alihnment coil leading-out terminal can change in low voltage range.
Further, binding post 31 is provided with 12,12 binding posts 31 are divided into upper and lower two parts, every part all has 6 binding posts 31, the positional alignment of upper and lower two-part binding post 31 is consistent, when wiring, need binding post 31 corresponding for two positions to connect together, 12 binding posts 31 form 5 fine setting grades altogether.
Further, as shown in Figure 4 and Figure 5, pressure regulation panel 2 is provided with pressure regulation terminal 21, and pressure regulation terminal 21 is connected by connecting rod 4.Connecting rod 4 changes the connection between pressure regulation terminal 21, in realization coil series and parallel between conversion, thus obtain different electric pressures.
Above content is in conjunction with concrete execution mode further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made.
