Abstract

A ventilating and noise-reducing apparatus for an indoor transformer is disclosed. The ventilating and noise-reducing apparatus comprises a ventilating louver and an axial flow fan used for performing ventilation and thermal dissipation to ensure a safe and stable operation of the indoor transformer, a multi-channel active control system used for the ventilating louver and mounted on the exterior of the ventilating louver, and a single-channel or multi-channel active control system used for the axial flow fan and mounted on the exterior of the axial flow fan. Due to the ventilating louver and the axial flow fan, the ventilation and thermal dissipation of the indoor transformer are ensured; and meanwhile, due to the active control systems, noise generated by the indoor transformer is restrained from radiating to the outside from the ventilating and thermal dissipating channels.

Description

technical field [0001] The invention belongs to the technical field of indoor transformers, belongs to the technical field of environmental engineering specialty noise pollution prevention and control, and particularly relates to an indoor transformer ventilation and noise reduction device. 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 ...
