Abstract
The utility model discloses a transformer noise reduction box which comprises a box body, and a box wall of the box body is in a double-layer structure which is composed of an inner plate and an outer plate. A sound absorption plate is arranged between the inner plate and the outer plate. A ventilation opening is arranged in the box wall. In the transformer noise reduction box, the box wall is designed to be in the double-layer structure and the sound absorption plate is added between the inner plate and the outer plate. Accordingly, noise produced during the operation process of a transformer is effectively obstructed to be transmitted outside the box body. The transformer noise reduction box is simple in structure, novel in design, and high in promotion value.
Description
Technical field
The utility model belongs to transformer noise reduction technology field, relates in particular to a kind of transformer noise reduction casing.
Background technology
Power transformer is widely used in the city load center, along with people are more and more higher to the requirement of living environment, the noise of transformer has brought to people and has seriously influenced, existing transformer-cabinet is much more general, and what consider is insult and the anti-electromagnetic radiation that prevents foreign object (for example mouse), to avoid to the damage of the transformer in the shell with to the pollution of surrounding environment.And noise pollution also be to surrounding environment pollute a kind of, society is increasingly strict to various noise pollutions other shore standard, each electricity consumption department for transformer noise require corresponding more and more higher.How each transformer manufacturer studies noise reduction from changing and optimize the transformer internal structure, but considers to change transformer case and reduces noise pollution to surrounding environment.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of simple and effective transformer noise reduction casing.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of transformer noise reduction casing comprises casing, the double-decker of the tank wall of casing for being consisted of by inner panel and outside plate, and between inner panel and outside plate, be provided with abatvoix, be provided with ventilating opening on the described tank wall.
Described transformer noise reduction casing, its abatvoix is mandruka or mineral wool.
Owing to adopting technique scheme, the utlity model has following superiority:
This transformer noise reduction casing, tank wall is designed to double-decker, and between inner and outer plates, sets up abatvoix, effectively intercepted the noise that produces in the transformer running to the conduction of casing outside, the utility model is simple in structure, design is novel, has larger promotional value.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of A-A among Fig. 1;
Among the figure: the 1-casing; The 2-outside plate; The 3-abatvoix; The 4-inner panel.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2, a kind of transformer noise reduction casing comprises casing 1, the double-decker of the tank wall of casing 1 for being consisted of by inner panel 4 and outside plate 2, and between inner panel 4 and outside plate 2, be provided with abatvoix 3, be provided with ventilating opening on the tank wall of described casing.Described abatvoix 3 is mandruka or mineral wool.
Transformer noise reduction casing of the present utility model is designed to double-decker with tank wall, and sets up abatvoix between inner and outer plates, has effectively intercepted the noise that produces in the transformer running to the conduction of casing outside
