Description
Technical field
The present invention relates to technical field of electric equipment, especially ring main unit sound-absorbing set.
Background technology
Ring main unit is that one group of transmission ＆ distribution electrical equipment is mounted in metal or non-metallic insulation cabinet or makes assembled compartment ring
The electrical equipment of net power supply unit, core use on-load switch and fuse, have simple in structure, small, price
It is low, the advantages that power supply parameter and performance and power supply safety can be improved.Due to being high-voltage electricity gas apparatus, in operational process, cabinet
Some internal ancillary equipments easy to produce some noises, and ring main unit is mainly used for Urban Residential District, skyscraper, large size
In the power distribution station and box-type substation of the load centers such as public building, factory and enterprise, noise influences the environment on periphery too much.Cause
This can be equipped with corresponding noise-reducing device on the building of the power distribution station of modernization, and in some old power distribution station transformation process
In, the noise control improvement cost of building is higher, long construction period.
Invention content
In view of the above technical problems, the present invention will provide a kind of sound-absorbing set, dedicated for ring main unit so that ring main unit is included
Noise reduction is arranged, without being transformed to power distribution station building.
In order to solve the above technical problems, the technical scheme is that：
Ring main unit sound-absorbing set, including abatvoix, abatvoix are mounted on the cabinet outer wall of ring main unit, and the abatvoix passes through bent angle
Connection strap forms the sound-absorbing set in three faces, and the sound-absorbing set in three faces is mounted on outside cabinet, and positioned at three faces other than cabinet cabinet door
On vertical outer wall, there are gaps as heat dissipation interlayer between abatvoix and cabinet outer wall；The sound-absorbing covers top and connect
Top plate connects；Connection top plate is located at the top of cabinet；Multiple supporting rods are distributed on the inside of the abatvoix, support boom end is withstood on
On cabinet outer wall.
The supporting rod includes bolt, and bolt one end is fixed on abatvoix, and the other end connects top plate, and top plate withstands on cabinet
On external wall.
Preferred design, the connection top plate includes the triangular connecting plate and a horizontal connecting plate at a pair of of right angle；It is described
Two right-angle sides of triangular connecting plate be separately fixed at adjacent abatvoix top edge；The both ends of the horizontal connecting plate point
It is not fixed on the top edge of opposite abatvoix.
Further, sound-absorbing set both sides of the edge are connect with cabinet cabinet door both sides of the edge by cushion block, the pad
Block right angle setting, cushion block top are connect with horizontal connecting plate.
Ring main unit sound-absorbing set provided by the invention, it is simple in structure, it is quick for installation, it, can be quick during site operation
Outside ring main unit, ring main unit, power distribution station building need not be all transformed, so that it may to achieve the purpose that noise reduction.
Description of the drawings
Fig. 1 is the overlooking structure diagram of the present invention.
Specific implementation mode
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
As shown in Figure 1, ring main unit sound-absorbing set, including abatvoix 1, abatvoix 1 are mounted on 7 outer wall of cabinet of ring main unit, institute
The abatvoix 1 stated is made up of the sound-absorbing set in three faces bent angle connection strap 6, and the sound-absorbing set in three faces is mounted on outside cabinet 7, and is located at
On the vertical outer wall in three faces other than 7 cabinet door of cabinet, there are gaps as heat dissipation interlayer between 7 outer wall of abatvoix 1 and cabinet
8；The sound-absorbing set top is connected with top plate is connect；Connection top plate is located at 7 top of cabinet；The 1 inside distribution of abatvoix
There are multiple supporting rods, support boom end to withstand on 7 outer wall of cabinet.
Sound-absorbing covers and is not fixedly connected with relationship between cabinet 7, but sound-absorbing can be covered entirety by top connecting plate
It is sleeved on outside cabinet 7, in order to keep radiating, is separated by supporting rod between 7 side wall of blimp and cabinet, supporting rod can also play
Stablize the structure of blimp.
The supporting rod includes bolt 4, and 4 one end of bolt is fixed on abatvoix 1, and the other end connects top plate 3, top plate 3
It withstands on 7 outer wall of cabinet.Top plate 3 expands the contact area with 7 outer wall of cabinet, avoids field of load is small 7 side wall of cabinet is caused to become
Shape.
The connection top plate includes the triangular connecting plate 2 and a horizontal connecting plate 5 at a pair of of right angle；The triangle joint
Two right-angle sides of plate 2 are separately fixed at adjacent 1 top edge of abatvoix；The both ends of the horizontal connecting plate 5 are fixed respectively
In the top edge of opposite abatvoix 1.Triangular connecting plate 2 and horizontal connecting plate 5 can keep the shape that sound-absorbing covers, can be with
Form the top that a top connecting plate is placed on cabinet 7.
The sound-absorbing set both sides of the edge are connect with 7 cabinet door both sides of the edge of cabinet by cushion block 6, and the cushion block 6 is vertical
Installation, 6 top of cushion block are connect with horizontal connecting plate 5.Cushion block 6 plays the role of sizing, is carried out shaping to sound-absorbing set, and places suction
Sound set is detached from cabinet 7.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, several improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
