Technical field
This utility model relates to a kind of vibration isolator, particularly to the double-deck special vibration isolator of a kind of transformer separation type.
Background technology
Along with the development in city, in view of the restriction of the reasons such as place, power distribution room is more and more arranged at residential block
In interior basement or special machine room.According to associated mechanisms investigation statistics, the structure-borne noise caused by current power distribution room becomes
The main source of architecture indoor sound pollution, corresponding noise complains event to be the most just continuously increased.For transformer noise, main
The electromagnetic noise produced when if it runs and mechanical noise, and wherein by the electromagnetic force in the magnetostriction of stalloy and winding
This noise of point caused accounts for major part.In the power distribution room of residential block, house transformer is mostly dry-type transformer, its magnetostriction
The vibration of the transformer body caused be the supply frequency (50Hz) with twice for its fundamental frequency, therefore transformator vibration outwards transmission
Frequency be mainly 100Hz and the frequency multiplication with 100Hz, belong to dither, and this dither easily pass through works
Outwards transmission, causes large effect to people's living environment.
Show based on noise transfer theory primary Calculation, transformator the indoor noise caused pollutes and is mainly drawn by its vibration
The solid-borne noise risen causes, and negligible by the raw impact of airborne diffraction；And drawn by Practical Project,
Eliminating transformer structure-borne sound pollutes the measure that mainly should take vibration isolation.At present, the transformer noise of power distribution room controls general employing
Sound absorption, sound insulation measure or simple single-layer partiting polarization system.Wherein install additional outside transformator sound proof box and Sound-proof material or transformer station and
Power distribution room wall adds one layer of acoustic board and baffle, often air-borne sound is controlled effect preferable, and to structure-borne sound communication effect
Poor, and distribution indoor temperature also can be brought to rise high unfavorable factor；Simple single-layer partiting polarization system is only to lower frequency region vibration
Isolation ratio is relatively effective, and the dither for more than 100Hz disturbs, and vibration isolating effect is unsatisfactory.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of transformer separation type
