Design and building technology field.
Background technology
Because site condition is limited, comparison and choice need to consider that load, outlet, land status, flood discharge, periphery whether there is
Stone ore, oil depot, cement plant etc. factor, often can only one each side factor of comprehensive selection be relatively reasonable but periphery noise control will
Ask relatively rigorous site.Often there are following features such site：First, site nearby residents are to noise-sensitive；2nd, according to simulation
Level of noise is calculated, the noise that transfinites is implicitly present in；3rd, noise-sensitive point in site periphery is removed difficult.
Transformer station's Main Noise Sources are main transformer, with the continuous progress of power equipment manufacturing technology and designing technique,
Engineering general layout small, influence of the noise to periphery is especially prominent.Routine noise-reduction method has at present：Using indoor
Change, removal noise-sensitive point, noise source is added four sides enclose sound barrier, sound barrier added to the face of noise source three and factory circle is added
Sound barrier etc..Indoor change cost is high, and limited space, wiring is limited, and need to be used together with reference to HVAC, fire-fighting etc., is not suitable for
Mountain area field site form；Removal noise-sensitive point sound is big, and cost is big, and policy processing is difficult；Four sides is added to noise source to enclose
Chorus barrier, with reference to main transformer characteristic, the requirements such as ventilation, visual, fire prevention, sound insulation need to be met by enclosing material, by a variety of sound-deadening and noise-reducings
Material combines composition fireproof fence, and sound-deadening and noise-reducing equipment is long and complex using silk floss, and there are problems that；To noise
The face of source three adds sound barrier and adds factory's circle sound barrier, and because factory's circle sound barrier height is high, width is wide, the general cloth in factory's circle enclosure wall side
Important switchgear is equipped with, once this sound barrier run-off the straight or dropping, will cause great to substation safety operation
Potential safety hazard.
By theoretical calculation and field measurement practice have shown that：The height and structural form of each building, wall table in site
Facestock material, the acoustic power level and directive property of sound source, terrain parameter, meteorological condition, the computer capacity of sound field, the sky of noise-sensitive point
Between position etc. be control noise source important parameter value.Therefore the parameter such as Combining with terrain, according to the space of noise-sensitive point
Deployment scenarios, one economical rationality of selection, environment-friendly for arranging the floor plan of transformer station and suiting measures to local conditions of making rational planning for
Novel noise reduction measure seem particularly critical.
The content of the invention
The purpose of this utility model is to overcome not enough present on existing conventional main transformer noise reduction mode, with reference to place ring
Border, meteorological condition, floor plan is reasonable there is provided a kind of structure composition, safe, durable, good reliability, economical rationality, O＆M
It is convenient, to the U-shaped noise reduction fire rated wall structure of the less main transformer of influence on system operation.
The purpose of this utility model is completed by following technical solution, a kind of U-shaped noise reduction fire wall of main transformer
Structure, three sides that it is included in main transformer add the fire wall of concrete frame structure, form the "U" shaped drop that three faces are enclosed
Make an uproar fire wall, the fire wall of three side concrete frame structure, be included on the basis of conventional civil engineering fire prevention foundation of wall, framework plus
If the fire prevention foundation of wall that three faces are enclosed, add grade beam and be laid with electrically, fire-fighting built-in fitting and built-in pipe, the fire prevention foundation of wall
On poured beam column and wall.
As preferred：The power distribution equipment side of the fire wall, is reserved with the hole that main transformer is connected with equipment, and in hole
It is embedded with mouthful in angle steel, hole and is placed with electric wall bushing, and steel plate and angle of the electric wall bushing by disjunctor
Steel is connected, and also closure has waterproof material on hole；The surface of the wall is equipped with reinforced mesh and has rendering layer.
As preferred：The absorbent treatment being made of applied fireproofing, the absorbent treatment are also equipped with described fire wall
It is grounded with civil engineering fire wall, and the noise reduction coefficient NRC of fire wall is not less than 0.9；The height of fire wall is not less than 9m.
The utility model is mainly the reasonable Arrangement by general layout, and fire wall is added in the side of main transformer three, is formed
The "U" shaped noise reduction fire wall that three faces are enclosed, wall is high and metope sound-absorbing material requires to set according to noise reduction, the usual height of transformer station
If 9m；Wall with flues side of not setting up defences considers the transport of main transformer, installs and safeguard, main transformer and equipment connect through skill through walls
Art is connected.
The utility model compared with prior art, make use of conventional " two " font two panels fire wall, in noise-sensitive point
Direction increase sets one of noise reduction wall and is connected, and structural system uses concrete frame structure；With structure composition rationally,
Safe, durable, good reliability, economical rationality, O＆M are convenient, the features such as smaller to influence on system operation.
