Abstract

The utility model discloses a kind of low-loss dry type amorphous transformers, including interior amorphous iron core ring, outer amorphous iron core ring is bonded on the outside of the interior amorphous iron core ring, the left and right sides of the interior amorphous iron core ring and outer amorphous iron core ring, which is closely rolled up, coil, puigging is bonded on the outside of the outer amorphous iron core ring, the inside of the puigging includes epoxy resin layer, deadening felt, glass layer, rock wool fibers layer and silicon nitride ceramics layer.Deadening felt, glass layer and rock wool fibers layer have good insulating properties, and because of their internal irregular capillary structures, it can be by the noise absorption of entrance, and noise is flowed out from fiber gap on a small quantity, silicon nitride molecular arrangement is fine and closely woven inside silicon nitride ceramics layer, has the special efficacy for blocking sound to propagate outward well, and puigging is integrally wrapped in transformer periphery, the amount that the noise of transformer generation is propagated outward can be effectively reduced, effect is more ideal.

Description

A kind of low-loss dry type amorphous transformer

Technical field

The utility model relates to amorphous transformer technical field, specially a kind of low-loss dry type amorphous transformer.

Background technique

The country of research and development amorphous alloy transformer is the U.S. earliest in the world, is assumed responsibility at that time by General Electric Company The research and development program element of amorphous alloy transformer realizes merchandized handling to last century late nineteen eighties, a kind of new due to having used Soft magnetic materials amorphous alloy, the performance of amorphous alloy transformer surmounted all kinds of silicon steel transformers.

Existing dry type amorphous transformer conducts voltage by outer amorphous iron core ring and interior amorphous iron core ring between coil, Can make integrated transformers generate " drone " sound, existing method is rolled in outer amorphous iron using one layer of oil immersion insulation Cowhells paper bag The periphery of core ring, reduces the propagation of noise with this, but the soundproof effect of oil immersion Cowhells paper be not it is especially desirable, to transformer Soundproof effect is bad.

Utility model content

The purpose of this utility model is to provide a kind of low-loss dry type amorphous transformers, to solve in above-mentioned background technique The problem of proposition.

To achieve the above object, the utility model provides the following technical solutions: a kind of low-loss dry type amorphous transformer, packet Interior amorphous iron core ring is included, is bonded with outer amorphous iron core ring on the outside of the interior amorphous iron core ring, the interior amorphous iron core ring and outer The left and right sides of amorphous iron core ring, which is closely rolled up, coil, is bonded with puigging, the puigging on the outside of the outer amorphous iron core ring Inside include epoxy resin layer, deadening felt, glass layer, rock wool fibers layer and silicon nitride ceramics layer.

Preferably, the outside even application of the coil has insulating lacquer layer.

Preferably, the inside of the outer side bonds deadening felt of the epoxy resin layer, the outside adhering glass fiber of deadening felt The inside of layer, the inside of the outer side bonds rock wool fibers layer of glass layer, the outer side bonds silicon nitride ceramics of rock wool fibers layer The inside of layer.

Compared with prior art, the utility model has the beneficial effects that the low-loss dry type amorphous transformer, deadening felt, Glass layer and rock wool fibers layer have good insulating properties, and because of their internal irregular capillary structures, can will enter Noise absorption, and noise is flowed out from fiber gap on a small quantity, and silicon nitride molecular arrangement is fine and closely woven inside silicon nitride ceramics layer, has very The special efficacy that good blocking sound is propagated outward, and puigging is integrally wrapped in transformer periphery, can effectively reduce transformer generation The amount propagated outward of noise, effect is more ideal.

Detailed description of the invention

Fig. 2 is the main view local cutting schematic diagram of the utility model；

Fig. 3 is enlarged structure schematic diagram at a of the utility model.

In figure: amorphous iron core ring in 1,2 outer amorphous iron core rings, 3 coils, 4 insulating lacquer layers, 5 puiggings, 6 epoxy resin layers, 7 deadening felts, 8 glass layers, 9 rock wool fibers layers, 10 silicon nitride ceramics layers.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

In the description of the present invention, it should be understood that term " longitudinal direction ", " transverse direction ", "upper", "lower", " preceding ", The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on Orientation or positional relationship shown in the drawings is merely for convenience of description the utility model, rather than the dress of indication or suggestion meaning It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to the utility model Limitation.

Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of technical solution: a kind of low-loss dry type amorphous transformer, packet Interior amorphous iron core ring 1 is included, the outside of interior amorphous iron core ring 1 is bonded with outer amorphous iron core ring 2, interior amorphous iron core ring 1 and outer amorphous The left and right sides of iron core ring 2, which is closely rolled up, coil 3, and outer 2 tight type of amorphous iron core ring is wrapped in the outside of interior amorphous iron core ring 1, subtracts Few transformer noload losses, the outside of outer amorphous iron core ring 2 is bonded with puigging 5.

Refering to fig. 1 and Fig. 2, the outside even application of coil 3 have insulating lacquer layer 4, and the material of insulating lacquer layer 4 is polyvinyl alcohol Formal has good insulating properties and thermal insulation.

Refering to fig. 1 and Fig. 3, the inside of puigging 5 include epoxy resin layer 6, deadening felt 7, glass layer 8, rock wool Fibrous layer 9 and silicon nitride ceramics layer 10, the inside of the outer side bonds deadening felt 7 of epoxy resin layer 6, epoxy resin layer 6 have exhausted The outer side bonds rock wool of edge characteristic resistant to high temperature, the inside of the outside adhering glass fibrous layer 8 of deadening felt 7, glass layer 8 is fine The inside of layer 9 is tieed up, deadening felt 7, glass layer 8 and rock wool fibers layer 9 have good insulating properties, and because they are internal not Regular capillary structure, can be by the noise absorption of entrance, and noise is flowed out from fiber gap on a small quantity, and the outside of rock wool fibers layer 9 is viscous The inside of silicon nitride ceramics layer 10 is connect, 10 inside silicon nitride molecular arrangement of silicon nitride ceramics layer is fine and closely woven, has good blocking sound The special efficacy that sound is propagated outward.

When the utility model is specifically implemented: deadening felt 7, glass layer 8 and rock wool fibers layer 9 have insulation well Property, and because of their internal irregular capillary structures, it can be by the noise absorption of entrance, and noise is flowed out from fiber gap on a small quantity, 10 inside silicon nitride molecular arrangement of silicon nitride ceramics layer is fine and closely woven, has the special efficacy for blocking sound to propagate outward well, and sound insulation Layer 5 is whole to be wrapped in transformer periphery, can effectively reduce the amount that the noise of transformer generation is propagated outward, and effect is more ideal.
