Abstract
The utility model discloses a voltage transformer with an elbow head, comprising a wire frame, an iron core, a coil which is wound on the wire frame and an insulated shell which is wrapped on the iron core and the coil. The voltage transformer is characterized in that a fuse is installed in the insulated shell, the fuse is electrically connected with the coil, an elbow shaped cable head is installed on the insulated shell, and the elbow shaped cable head is electrically connected with the fuse. Solid insulation materials are arranged in the insulated shell, a secondary panel nut is installed on the insulated shell, the secondary panel nut is connected with the coil through a connecting wire. The inner insulation of the utility model changes the oil insulation into the solid insulation, the problems of leaking oil and dielectric loss and the like when the oil insulation is used are resolved, the maintenance can be exempted, the explosion-proof ability and the over-voltage resistance ability are increased. In the utility model, the elbow shaped cable head is installed on the insulated shell, the traditional voltage primary wire-out is changed, and a replaceable fuse is arranged in the insulated shell, the additional installation of the fuse is not needed, thereby the space floor area of the voltage transformer is decreased.
Description
Technical field
The utility model relates to a kind of voltage transformer.
Background technology
The voltage transformer majority that uses in electric power system at present is the oil immersed type single-phase potential transformer, what this voltage transformer adopted is oil-insulation, thereby there is a problem of dielectric loss, leakage of oil, need often to safeguard, it also has the shortcoming of explosion-proof ability, anti-overvoltage ability simultaneously, can not be used with box-type substation, and the voltage transformer that uses at present needs in addition subsidiary external insurance.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of do not have oiling, no dielectric loss, the good voltage transformer of non-maintaining, explosion-proof and anti-overvoltage ability.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of band elbow head voltage transformer, comprise wire frame, iron core, be wrapped in the coil on the wire frame and be coated on iron core and coil on insulation crust, it is characterized in that in the described insulation crust fuse being installed, described fuse is electrically connected with coil, elbow type cable end is installed on insulation crust, and elbow type cable end is electrically connected with fuse, in this insulation crust solid insulating material is housed, secondary embedding mother is installed on the insulation crust, and the secondary embedding is female to be connected by connecting line with coil.
Above-mentioned insulation crust is provided with installs the embedding mother.
The beneficial effects of the utility model are: insulation changes oil-insulation into solid insulation in of the present utility model, and problems such as the leakage of oil that has existed when having solved the employing oil-insulation, dielectric loss can be non-maintaining, improves explosion-proof ability and anti-overvoltage ability; The utility model is equipped with elbow type cable end on insulation crust, changed an outlet of traditional voltage, and insulation crust is built-in with the changeable type fuse, need not install in addition, has reduced the space floor space of voltage transformer.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a sectional structure schematic diagram one of the present utility model;
Fig. 2 is a sectional structure schematic diagram two of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of band elbow head voltage transformer that the utility model provides, comprise wire frame 1, unshakable in one's determination 2, be wrapped in the coil 3 on the wire frame 1 and be coated on unshakable in one's determination 2 and coil 3 on insulation crust 4, fuse 5 is installed in insulation crust 4, described fuse 5 is electrically connected with coil 3, elbow type cable end 6 is installed on insulation crust 4, elbow type cable end 6 is electrically connected with fuse 5, the utility model has changed an outlet of traditional voltage, and insulation crust is built-in with the changeable type fuse, need not install in addition, reduce the space floor space of voltage transformer.
Solid insulating material 7 is housed, thereby by changing oil-insulation into solid insulation, problems such as the leakage of oil that has existed when having solved the employing oil-insulation, dielectric loss can be non-maintaining, improves explosion-proof ability and anti-overvoltage ability in insulation crust 4.
