Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0033] like Figure 1-3 As shown, the present invention provides a ventilation and noise reduction device for indoor transformers, which includes ventilation louvers 2 and axial flow fans 3 located in the openings of the wall for ventilation and heat dissipation to ensure the safe and stable operation of the indoor transformer 1. The louvers 2 and the axial flow fan 3 are respectively located on two walls; the first type of active control mechanism 4 located outside the louver 2 is used to reduce the noise radiated from the indoor transformer from the ventilation louver 2; 3 The second type of external active control mechanism 5 is used to reduce the noise radiated from the indoor transformer 1...

Abstract

The invention provides a ventilation and noise reduction device of an indoor transformer. The device comprises a ventilation louver and an axial flow fan located in wall body openings, a first-type active control mechanism located outside the louver, and a second-type active control mechanism located outside the axial flow fan, wherein the ventilation louver and the axial flow fan are used to implement ventilation and heat dissipation and ensure safe and stable running of the indoor transformer, and the louver and the axial flow fan are located on two wall bodies respectively; the first-type active control mechanism is used to reduce noise radiated by the indoor transformer from the ventilation louver to external environments; the second-type active control mechanism is used to reduce noise radiated by the indoor transformer from a ventilation opening of the axial flow fan to the external environments and reduce noise radiated by the axial flow fan to the external environments; and the first-type active control mechanism and the second-type active control mechanism compose the active noise reduction system.

Description

technical field [0001] The invention belongs to the technical field of noise pollution prevention and control of environmental engineering, and in particular relates to a ventilation and noise reduction device for an indoor transformer. Background technique [0002] With the development of society, the electricity load is increasing, and many new substations are added, some of which are built near residential areas; on the other hand, with the expansion of cities, many new residential areas are built around substations that were originally located in remote areas. Therefore, the distance between substations and residential areas is getting closer and closer, and residents are affected by noise pollution from substations. [0003] Outdoor transformers often use traditional sound insulation and sound absorption technologies such as sound barriers and semi-sound insulation enclosures for noise control. In the case of close residential areas, it is very difficult and brings othe...
