Description

Amorphous alloy oil immersion type transformer

Technical field

The utility model relates to a kind of transformer technology field, and more particularly, it relates to amorphous alloy oil immersion type transformer.

Background technology

Non-crystaline amorphous metal is by super quench solidification, and during alloy graining, atom has little time ordered arrangement crystallization, and the solid alloy obtaining is long-range disordered structure, there is no crystal grain, the crystal boundary of crystal alloy.This non-crystaline amorphous metal has the performance of many uniquenesses, because its excellent performance, technique are simple, becomes the research and development emphasis of domestic and international material supply section educational circles since the eighties.Amorphous alloy transformer, with the advantage of himself, becomes the first-selected product of energy-saving and emission-reduction, meets the requirement of national energy-saving environmental protection policy policy simultaneously, has wide development space.Amorphous alloy material has the extremely low feature of loss, is applicable to doing the iron core of transformer, due to amorphous alloy core thickness as thin as a wafer, only have 0.02 to 0.03 millimeter, simultaneously amorphous alloy material is also very responsive to mechanical stress.When iron core frame and winding assembling, need to open open seam, suit winding and be connected again seam etc.These make stressed operation unshakable in one's determination can produce a large amount of iron core chips.Although the device body of product is assembled into coil, horizontal positioned unshakable in one's determination, after overlap joint, with the shutoff of M glue, can prevent that amorphous core fragment from dropping, inevitably there are some iron core chips to remain in device body, to properties of product, bring very large potential safety hazard.

At present, application number is the fuel tank that 201220653324.1 Chinese patent discloses a kind of oil-immersed type non-crystal alloy transformer, by the fuel tank to traditional oil-immersed type non-crystal alloy transformer, improve, utilize the absorption property of magnet that the iron core chips in oil tank body is absorbed, prevent that thereby iron core chips from entering the interior transformer short-circuit that causes of coil, propose a kind of simple in structure, the fuel tank of the oil-immersed type non-crystal alloy transformer that coefficient of safety is high, it comprises oil tank body, in described oil tank body, be provided with magnet, described magnet is positioned at the bottom of described oil tank body, magnet has two, and lay respectively at the two ends of oil tank body, magnet is placed in a can, the thickness of can is 1 to 4 millimeter, described magnet is permanent magnet.

The amorphous alloy iron core fragment of the fuel tank internal of this amorphous alloy oil immersion type transformer follows insulating oil to flow, when arriving the fuel tank bottom of oil-immersed type non-crystal alloy transformer, although be subject to the attraction of magnet, can be by magnet adsorption on can, avoid fragment to flow into the hidden danger that causes short circuit in coil, after but fragment is adsorbed, surface in can always, along with flowing of insulating oil, the weak fragment of the fragment that some are tiny and other magnetic can be pulled away, reenter in insulating oil and flow, or can there is the phenomenon that fragment flows into coil, and can is arranged at oil tank of transformer bottom, cleaning is very inconvenient.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of amorphous alloy oil immersion type transformer, stops to occur that fragment after being adsorbed comes back in insulating oil that the potential safety hazard that fragment flows into coil occurs, simple in structure, safety durable, long service life.

For achieving the above object, the utility model provides following technical scheme: a kind of amorphous alloy oil immersion type transformer, comprise transformer body, shown in transformer body inside be provided with amorphous alloy iron core, coil and insulating oil, described transformer body is provided with oil pipe and for adsorbing the fragment adsorbent equipment of the amorphous alloy iron core fragment of insulating oil, described fragment adsorbent equipment is connected with delivery valve, fragment adsorption box and inlet valve in turn by oil pipe, and fragment adsorbent equipment also comprises for driving the mobile oil pump of insulating oil.

By adopting technique scheme, insulating oil in transformer body is under the effect of oil pump, by delivery valve, enter fragment adsorption box through absorption, pass through again afterwards inlet valve inflow transformer body, utilize fragment adsorbent equipment absorption amorphous alloy iron core fragment, can make amorphous alloy iron core fragment depart from the inside of transformer body, stop to occur that the fragment after being adsorbed comes back in insulating oil, the potential safety hazard that fragment flows into coil occurs; And fragment adsorbent equipment is simple in structure, easy accessibility, when fragment adsorption box reaches capacity state, staff can close oil pump, inlet valve and delivery valve at any time, open that fragment adsorption box is cleared up or maintenance, maintenance work, the operating efficiency that guarantees fragment adsorbent equipment, makes amorphous alloy oil immersion type transformer safe, durable, long service life.

The utility model is further set to: described fragment adsorption box comprises sidewall and bottom, and described sidewall is provided with magnet, and bottom is provided with for preventing that non magnetic fragment from entering the screen pack of transformer body inside.

By adopting technique scheme, magnet is set on the sidewall of fragment adsorption box for adsorbing the amorphous alloy iron core fragment of insulating oil, make the compact conformation of fragment adsorption box inside, when insulating oil passes through fragment adsorption box, can guarantee that fragment absorption puts in place, simultaneously in the position of outlet at bottom, be provided with screen pack, can also prevent that weak and other the non magnetic fragments of magnetic from entering transformer body inside, guarantees the insulating oil free from admixture of transformer body inside.

The utility model is further set to: described delivery valve and inlet valve are unidirectional valve.

By adopting technique scheme, utilize unidirectional valve can prevent that fragment adsorbent equipment is when quitting work, the fragment in fragment adsorption box flows backwards back along with insulating oil in transformer body.

The utility model is further set to: described screen pack is metal filter screen.

By adopting technique scheme, metal filter screen resistance is low, corrosion-resistant, can repeatedly clean, and economy is high, and safe, firm, long service life.
