Description
Technical field
The utility model relates to a kind of oil-immersed current transformer, especially a kind of oil-immersed current transformer of handstand.
Background technology
The general oil standing upside down is invaded formula current transformer and on the top of insulator, is provided with an Oil Tank, is provided with secondary coil in Oil Tank, and such oil-immersed current transformer height is high, and center of gravity is also high, transports and uses dangerously, easily topples over.
Therefore, be necessary to provide a kind of new oil-immersed current transformer, to address the above problem.
Utility model content
The purpose of this utility model is to provide a kind of transportation and safe and reliable oil-immersed current transformer.
The technical scheme that realizes the utility model object is: a kind of oil-immersed current transformer, it comprises insulator, is covered in the cover plate of described insulator top, is installed on the expander on described cover plate, and described oil-immersed current transformer also comprises the secondary coil being installed in described insulator.
As prioritization scheme of the present utility model, the top of described insulator is thicker than bottom, and described insulator is back taper.
As prioritization scheme of the present utility model, described oil-immersed current transformer also comprises grounded conduit, is installed on the base of described insulator below, the bottom of described grounded conduit is fixed on described base, and the top of described grounded conduit is welded on described secondary coil.
Compared with prior art, the utility model oil-immersed current transformer at least has the following advantages: oil-immersed current transformer of the present utility model has omitted Oil Tank, a lot of seal points have been reduced, significantly reduced the whole height of oil-immersed current transformer simultaneously, the transformer oil needing in oil-immersed current transformer has also reduced, and has lightweight, decentralization, sealing is reliable, cost is low, transportation and safe and reliable feature.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below:
Fig. 1 is the structural representation of the current transformer of prior art.
Fig. 2 is the structural representation of the utility model current transformer.
Embodiment
As shown in Figure 2, the utility model is a kind of oil-immersed current transformer, below in conjunction with accompanying drawing, working mechanism of the present utility model is described further.
Oil-immersed current transformer comprises insulator 4, be installed on secondary coil 5 in insulator 4, be welded in grounded conduit 6 on secondary coil 5, be installed on described insulator 4 belows base 7, be covered in insulator 4 tops cover plate 3, be installed on the expander 1 of cover plate 3 tops, by the wire 2 passing on cover plate 3, in insulator 4, be full of transformer oil.
One time wire 2 is connected on cover plate 3 through secondary coil 5 centers.Grounded conduit 6 tops are welded on secondary coil 5, and grounded conduit 6 bottoms are fixed in base 7, and secondary coil 5 is firmly fixed.
Insulator 4 is back taper, and the top of insulator 4 is thicker than bottom.Because insulator 4 is back taper, the space of its tapering part is strengthened, the insulation at delta-shaped region 8 places of secondary coil 5 just can be strengthened (holding thickening) like this, is greatly better than secondary coil of the prior art Delta Region, has greatly improved the insulation property of oil-immersed current transformer.
Oil-immersed current transformer in the utility model has omitted Oil Tank, a lot of seal points have been reduced, significantly reduced the whole height of oil-immersed current transformer simultaneously, the transformer oil needing in oil-immersed current transformer has also reduced, and has lightweight, decentralization, sealing is reliable, cost is low, transportation and safe and reliable feature.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
