Description

Small-sized dustproof transformer

Technical field

The utility model relates to a kind of transformer, relates in particular a kind of small-sized dustproof transformer.

Background technology

When transformer uses in equipment, because can making the class of insulation of transformer, the impact of airborne dust etc. reduces, in the time that the insulation sheath of transformer coil is damaged, can make the direct conducting of transformer coil, can cause some safety problems such as transformer short-circuit, electric leakage, these problems can cause transformer to burn out or cannot normally work.

Having notification number is that the patent of CN 202632990U discloses a kind of water proof and dust proof transformer, comprise transformer framework, on transformer framework, be wound with coil, transformer framework is provided with E shaped iron core, E shaped iron core is by the first iron core arm, the second iron core arm, the 3rd iron core arm, the 4th iron core arm composition, the second iron core arm inserts the through hole at transformer framework center, the first iron core arm, the 3rd iron core arm lays respectively at the both sides of transformer framework and wraps up coil both sides, before and after described transformer framework, be respectively equipped with involucrum, between coil and involucrum, between coil and the first iron core arm, in space between coil and the 3rd iron core arm, fill oil ring epoxy layer, although the transformer of this structure can be good at solving dust and enters into the problem that makes coil short in coil, but because transformer can produce very large magnetic field in the process of operation, this magnetic field will constantly be adsorbed onto the dust in environment on transformer, dust will constantly overstock on the top layer of transformer like this, clean also inconvenience very, will cause like this heat dispersion variation of transformer, finally there is the problem that transformer burns.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of small-sized dustproof transformer convenient for cleaning.

For achieving the above object, the utility model provides following technical scheme: a kind of small-sized dustproof transformer, comprise transformer framework and iron core, on described transformer framework, be wound with coil, described iron core penetrates in transformer framework, described coil is provided with dust-proof rack, in described dust-proof rack, be provided with several Air Filters, described coil is provided with hyoplastron, and described hyoplastron dorsad transformer framework one side is provided with buckle, described dust-proof rack is provided with draw-in groove, and described buckle wears in draw-in groove.

By adopting technique scheme, in making transformer, only need first by transformer framework, between coil and iron core, assemble, make dust-proof rack simultaneously, then the draw-in groove on dust-proof rack is aimed to the buckle on transformer framework, then buckle penetrates in draw-in groove, so just complete one dust-proof rack has been fixed to the effect on transformer framework, make dust-proof rack encase coil, prevent that dust from entering in coil, when use of long duration after, on dust-proof rack, pile up a lot of dusts, at this moment just dust-proof rack can be disassembled from transformer framework, then the cleaning of taking away, cleaning is loaded on after completing, reach an effect convenient for cleaning, effectively avoid because dust is excessively piled up and caused the heat dispersion of transformer to go wrong.

The utility model is further set to: described dust-proof rack is made up of three anti-red dogs perpendicular to each other, and in the time that dust-proof rack is fixed on transformer framework, dust-proof rack, transformer framework and hyoplastron formation one encase the enclosure space of coil.

One end that described buckle penetrates in draw-in groove is provided with arc surface.

By adopting technique scheme, just to be the shape of three faces perpendicular to each other on a cuboid identical for the shape of dust-proof rack like this, dust-proof rack just can form an airtight cuboid that wraps coil with the plate of hyoplastron, transformer framework and transformer framework below like this, reach and prevent that dust from entering into the effect in coil, simultaneously by the setting of arc surface, can the slippage in buckle penetrates draw-in groove seem more level and smooth, be not easy to occur the problem of blocking.

Fig. 2 is the enlarged drawing of A portion in Fig. 1.

In figure: 1, transformer framework; 2, iron core; 3, coil; 31, dust-proof rack; 311, draw-in groove; 32, hyoplastron; 321, buckle.

Embodiment

Shown in 2, the small-sized dustproof transformer of one of the present embodiment, comprise transformer framework 1 and iron core 2, on described transformer framework 1, be wound with coil 3, described iron core 2 penetrates in transformer framework 1, described coil 3 is provided with dust-proof rack 31, in described dust-proof rack 31, be provided with several Air Filters, described coil 3 is provided with hyoplastron 32, and described hyoplastron 32 dorsad transformer framework 1 one sides is provided with buckle 321, described dust-proof rack 31 is provided with draw-in groove 311, and described buckle 321 wears in draw-in groove 311.

By adopting technique scheme, in making transformer, only need first by transformer framework 1, between coil 3 and iron core 2, assemble, make dust-proof rack 31 simultaneously, then the draw-in groove on dust-proof rack 31 311 is aimed to the buckle 321 on transformer framework 1, then buckle 321 penetrates in draw-in groove 311, so just complete one dust-proof rack 31 has been fixed to the effect on transformer framework 1, make dust-proof rack 31 encase coil 3, prevent that dust from entering in coil 3, when use of long duration after, on dust-proof rack 31, pile up a lot of dusts, at this moment just dust-proof rack 31 can be disassembled from transformer framework 1, then the cleaning of taking away, cleaning is loaded on after completing, reach an effect convenient for cleaning, effectively avoid because dust is excessively piled up and caused the heat dispersion of transformer to go wrong, wherein the dust-proof rack 31 here adopts plastic material (preferably ABS) to make, Air Filter is by being inserted into its edge in dust-proof rack 31, so affixed mode of a similar existing screen cloth, Air Filter is fixed on dust-proof rack 31, and because having both sides, the coil 3 of miniature transformer passes transformer framework 1, so here dust-proof rack 31 is provided with two, it is one to be up and down the cuboid of capping that two dust-proof racks 31 are combined, separated in this cuboid, be divided into two present dust-proof racks 31.
