Abstract
The utility model relates to a combined transformer, which consists of a shell, an oil tank, a load switch, high-voltage cable elbows, an no-excitation tap changer, dual-sensitive fuses, a standby fuse, an oil-immersed transformer, low-voltage conducting rods and grounding devices. The transformer can combine high-voltage switchgear, an oil-immersed power distribution transformer and low-voltage switchgear together, can automatically transform voltage and can regulate high voltage to voltage for civil use. The no-excitation tap changer of the oil-immersed transformer can regulate voltage level under the condition of no excitation to ensure that residents can use electricity with stable voltage.
Description
Technical field
The utility model belongs to field of electrical equipment.
Background technology
Nearly all be to use transformer at present in electric power, telecommunications, automation control system, along with the electrified development of industrial and mining enterprises, various industrial production mechanical electric equipment also often need to use transformer, according to different places, different environments for use, the transformer of various difference in functionalitys arises at the historic moment.
Combined transformer, it is the removable transformation device that high voltage switchgear, oil-immersed distributing transformer, low voltage switchgear are combined.It not only has the characteristics that European case becomes, and has also that volume is littler, hermetically sealed, all insulation, power supply is reliable, installation is rapid, flexible, easy to operate, loss is little, can go deep into load center, reduce line loss, appearance looks elegant, strong to environmental adaptation, reliable and small investment.Advantages such as instant effect.Be widely used in the public distribution in city, skyscraper, residential quarters, park, highway, also be applicable to oil field, industrial and mining enterprises and interim construction site.
Summary of the invention
The purpose of this utility model is according to actual needs, and a kind of combined transformer that high voltage switchgear, oil-immersed distributing transformer, low voltage switchgear are combined is provided.
The technical scheme that the utility model adopted is: through high voltage switchgear, make alternating current be converted to magnetic energy by transformer by the cable transmission high-tension electricity, magnetic energy is again by unshakable in one's determination, senses low-voltage coil and is converted to electric energy and exports from the low voltage switchgear side.
Structure of the present utility model comprises: shell, fuel tank, on-load switch, high-tension cable elbow head, non-excitation pressure adjustment switch, Lazer's fuse, backup fuse, oil-filled transformer, low pressure conducting rod, earthing device.
High-tension cable elbow head (1), on-load switch (2), non-excitation pressure adjustment switch (3), Lazer's fuse (4) are installed on shell (9) panel by perforate, oil-filled transformer (6), backup fuse (5) are installed in the fuel tank (10), low pressure conducting rod (7) is installed on the shell front deck low-pressure side panel, and earthing device (8) is welded on the housing face-plate.
The beneficial effects of the utility model are: transformer can be combined high voltage switchgear, oil-immersed distributing transformer, low voltage switchgear, and automatically converting voltage can be the electric pressure of high voltage adjusting to residential electricity consumption.Oil-filled transformer non-excitation pressure adjustment switch regulation voltage gear under the condition of no excitation, thus allow the resident use stable voltage.
Description of drawings
Fig. 1 is the utility model schematic top plan view, and Fig. 2 is the utility model schematic side view.
1. high-tension cable elbow heads among the figure, 2. on-load switch, 3. non-excitation pressure adjustment switch, 4. Lazer's fuse, 5. backup fuse, 6. oil-filled transformer, 7. low pressure conducting rod, 8. earthing device, 9. shell, 10 fuel tanks.
Embodiment
Introduced by high-tension cable, cable is connected on the high-tension cable elbow head (1).After the energising, electric energy passes through oil-filled transformer (6) thereby produces electromagnetic induction, produces magnetic energy and gives low-voltage coil with energy delivery.Draw electric energy from the low pressure conducting rod then.Can regulate the gear on the non-excitation pressure adjustment switch (4), change the number of turn of high-tension coil, change no-load voltage ratio, regulate user's required voltage.Lazer's fuse (4) backup fuse (5) all plays protection 1 secondary line effect.
