Abstract
The invention discloses a press-fitting inner supporting device for an amorphous alloy oil-immersed transformer coil. The inner supporting device comprises an upper end plate and a lower end plate which are arranged in parallel; a lower external thread column is welded to the lower surface of the upper end plate; an upper external thread column is welded to the upper surface of the lower end plate; the lower external thread column and the upper external column are connected through an internal thread pipe; a positioning part for alignment is arranged between the upper end plate and the lower end plate and comprises an upper positioning column welded to the lower surface of the upper end plate and a lower positioning column welded to the lower surface of the lower end plate; the lower positioning column is a hollow pipe; the lower end of the upper positioning column is inserted in the hollow pipe and is closely combined with the inner wall of the hollow pipe. According to the press-fitting inner supporting device, the distance between the upper end plate and the lower end plate is adjusted through threaded transmission of the internal thread pipe and the external thread column, and alignment of the upper end plate and the lower end plate is achieved through the guiding function of the positioning part. The inner supporting device has the advantages of being simple in structure, convenient to operate, small in specification number and high in universality.
Description
Technical field
The present invention relates to amorphous alloy oil immersion type transformer technology field, what particularly relate to a kind of amorphous alloy oil immersion type used in transformer coil press-fits inner support device.
Background technology
Amorphous alloy transformer adopts new magnetic material---amorphous alloy strips makes novel high-efficiency and energy-saving transformer unshakable in one's determination.The most outstanding feature of amorphous alloy transformer is exactly that no-load loss and no-load current are very little, is the extraordinary distribution transformer of current energy-saving effect.Two amorphous alloy transformer has been at home, overseas power networks has generally run during the last ten years for this.
At present, because amorphous alloy oil immersion type transformer device structure is compact, need shaping to press-fit solidifying and setting after coil winding completes, in whole process needs, band mould carries out.Press mounting die is many according to model physical dimension kind, for ensureing that the Workshop Production cycle is uninterrupted, often needs to make more mould to ensure the continuous firing of winding process employee.Because constantly making new mould, quantity is more, causes workshop mould to overstock in a large number.
Summary of the invention
The technical problem to be solved in the present invention is: what provide a kind of amorphous alloy oil immersion type used in transformer coil press-fits inner support device.This amorphous alloy oil immersion type used in transformer coil press-fit inner support device can solve amorphous alloy oil immersion type transformer coil adopt mould carry out press-fiting cause a large amount of mould overstock drawback, it adopts a kind of adjustable frock to replace press mounting die, reduce press mounting die stock waste, enhance productivity, reduce production cost.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is:
Amorphous alloy oil immersion type used in transformer coil press-fit an inner support device, comprise the upper head plate (1-1) and bottom plate (1-2) that be arranged in parallel; Lower external thread column (2-1) is welded with at the lower surface of described upper head plate (1-1); Upper external thread column (2-2) is welded with at the upper surface of described bottom plate (1-2); Connected by riffled tube (3) between described lower external thread column (2-1) and upper external thread column (2-2); The positioning element aligned is provided with between described upper head plate (1-1) and bottom plate (1-2); This positioning element comprises the upper reference column (5-1) being welded in upper head plate (1-1) lower surface and the lower reference column (5-2) being welded in bottom plate (1-2) lower surface; Described lower reference column (5-2) is hollow pipe; The lower end of upper reference column (5-1) to be inserted in described hollow pipe and is combined closely with the inwall of hollow pipe.
Further: to be provided with handle (4) at the outer wall of described riffled tube (3).
The advantage that the present invention has and good effect are:
By adopting technique scheme, in the present invention, realize highly regulating by the screw-driven of riffled tube and external thread column (upper external thread column and lower external thread column) between upper head plate and bottom plate, and realize aligning of upper head plate and bottom plate by the guide effect of positioning element.This press-fits inner support device and low pressure mould can be replaced to play stretching effect, and this structure is simple, convenient operation, the few highly versatile of specification.Stretching device in adopting, simple to operate, the quantity of low pressure mould can be reduced simultaneously, cost-saving, accelerate the turnover rate of low pressure mould, be convenient to field management.
Accompanying drawing illustrates:
Fig. 1 is the front view of the preferred embodiment of the present invention;
Fig. 2 is the vertical view of the preferred embodiment of the present invention.
Wherein: 1-1, upper head plate; 1-2, bottom plate; 2-1, upper external thread column; 2-2, lower external thread column; 3, riffled tube; 4, handle; 5-1, upper reference column; 5-2, lower reference column.
Embodiment
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of amorphous alloy oil immersion type used in transformer coil press-fit inner support device, comprise end plate, external thread column, riffled tube 3, reference column four parts; Wherein: end plate comprises the upper head plate 1-1 and bottom plate 1-2 that be arranged in parallel; External thread column comprises the lower external thread column 2-1 welded with the lower surface of described upper head plate 1-1, the upper external thread column 2-2 welded with the upper surface of described bottom plate 1-2; Connected by riffled tube 3 between described lower external thread column 2-1 and upper external thread column 2-2; Reference column is used for aligning upper head plate 1-1 and bottom plate 1-2; In the preferred embodiment: this positioning element comprises the upper reference column 5-1 being welded in upper head plate 1-1 lower surface and the lower reference column 5-2 being welded in bottom plate 1-2 lower surface; Described lower reference column 5-2 is hollow pipe; The lower end of upper reference column 5-1 to be inserted in described hollow pipe and is combined closely with the inwall of hollow pipe.
The use principle of above preferred embodiment is: first taken out from coil inside by low pressure mould, by the Height Adjustment between upper head plate 1-1 and bottom plate 1-2 extremely lower than internal coil diameter place, then put in the middle part of low-voltage coil, according to the size of drawing requirement, by regulating riffled tube 3, upper head plate 1-1 and bottom plate 1-2 realizes highly regulating by the screw-driven of riffled tube 3 with external thread column, and realize aligning of upper head plate 1-1 and bottom plate 1-2 by the guide effect of positioning element, upper head plate 1-1 and bottom plate 1-2 is adjusted to the size positions of requirement, the effect replacing mould can be realized.Simple to operate, production efficiency is high, accelerates mold turnover, reduces costs.
