Description
Technical field
The present invention relates to the design of the potential device of bellows and power equipment, a kind of metal bellow type oil conservater and metal bellows thereof are provided especially.
Background technique
Along with the continuous development and progress of society, the develop rapidly of each local economy, the use of electric energy also becomes more and more widely.In actual applications, after electric energy is transported to the electricity consumption zone, in order to adapt to the voltage request of consumer, also need to utilize transformer that voltage is reduced to the needed magnitude of voltage of each electric appliances by electric substations at different levels, as from the foregoing, power transformer in electric power system in occupation of consequence.
So-called power transformer is a kind of static electrical equipment, be the equipment that the alternating voltage (electric current) of a certain numerical value is become the identical another kind of or voltage (electric current) that several numerical value are different of frequency,, its Security directly has influence on the powered operation of electric power system.Oil conservater then is the protectiveness parts of large oil immersed formula transformer indispensability; it also is one of primary clustering of transformer; its effect is volumetric expansion or the contraction that the compensation insulating oil produces owing to temperature variation; and the insulating oil deficiency that causes because of leakage of oil of compensator transformer; simultaneously with insulating oil and air and water separation from; prevent insulating oil moisture absorption oxidation, perhaps more popularly say to be exactly to compensate volumetric expansion or the contraction that insulating oil produces because of temperature variation, guarantee to be full of oil in the oil-filled equipment body always.
Corrugated pipe oil tank is most widely used, and common outer oil type corrugated pipe oil tank all is circular horizontal bellows, because horizontal bellows under the floating function of oil, produces very big frictional force between bellows and the cabinet, often causes clamping stagnation; Also having a kind of bellows oil conservater is the upper cover plate that bellows one end is welded on oil conservater, the other end is welded on the bottom of oil conservater, form the tubbiness of a back-off, when transformer expands, oil enters in the bellows by the hole of oil conservater bottom, and its jack-up is come, and realizes compensation, its shortcoming is that the compensation utilization ratio is low, and activity is not freely.
Bellows is the critical component of corrugated pipe oil tank, and the compensation utilization ratio of oil conservater depends on the expansion contractility of bellows fully.Common bellows has crimping and the ripple bellows that rises, and these two kinds of bellows expansion less than 70%, when it shrinks, can cause about 30% waste to the utilization ratio of compressing.

Embodiment
The invention discloses a kind of metal bellows, improved the utilization ratio of bellows expansion to compression, reduced cost.The present invention also provides a kind of oil conservater with above-mentioned metal bellows.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7; The first dish-shaped wave plate structural representation that Fig. 1 provides for the embodiment of the invention; The second dish-shaped wave plate structural representation that Fig. 2 provides for the embodiment of the invention; The metal bellows structural representation that Fig. 3 provides for the embodiment of the invention.The metal bellow type oil storage vertical profile schematic representation that Fig. 4 provides for the embodiment of the invention; The full oil condition vertical profile schematic representation of metal bellow type oil conservater storage that Fig. 5 provides for the embodiment of the invention; The metal bellow type oil conservater that Fig. 6 provides for the embodiment of the invention is oiling state vertical profile schematic representation not; The cross-sectional schematic representation of metal bellow type oil conservater that Fig. 7 provides for the embodiment of the invention.
As shown in Figure 1, 2, the described metal bellows of present embodiment comprises a plurality of first dish-shaped wave plate 1, a plurality of second dish-shaped wave plate 2; The described first dish-shaped wave plate and the second dish-shaped wave plate stacked setting at interval; The inward flange of the described first dish-shaped wave plate welds with the inward flange of the second dish-shaped wave plate that is positioned at its below, and outward edge welds with the outward edge of the second dish-shaped wave plate of the side of being located thereon.Namely the first dish-shaped wave plate 1 is different with the opening angle of the second dish-shaped wave plate 2 because of adjacent two dish-shaped waveforms, so the welding back produces the nature angle, passes through the continuous connection of a lot of sheet dish wave plates like this, has just formed a bellows that expands naturally.
As shown in Figure 3, further, at above-mentioned metal bellows, the angle between the described first dish-shaped wave plate 1 and the second dish-shaped wave plate 2 is ɑ, and when metal bellows 6 one or both ends were subjected to pulling force or pressure, the excursion of angle ɑ was 0 °≤ɑ≤180 °.The transformation range of ɑ is more big, illustrates that the compensation utilization ratio of metal bellows 6 is more high.
Further, at above-mentioned metal bellows, the excursion of described angle ɑ is 0 °≤ɑ≤170 °.
