Noise reduction device for power distribution room
The invention relates to the technical field of power distribution equipment, in particular to a noise reduction device for a power distribution room. According to the technical scheme, the noise reduction device for the power distribution room comprises the power distribution room, a power distribution cabinet, a sound insulation layer, an air inlet pipe and an air outlet pipe. The air outlet pipe is divided into the first section, the second section and the third section, one end of the first section communicates with the air outlet, the other end of the first section communicates with the second section, and one end of the third section communicates with the second section. Air can flow to the first section from the interior of the containing cavity, then flow to the second section from the first section and finally flow to the third section. In the direction from the first section to the third section, the sectional area of the second section is in an increasing trend, and the accommodating volume of the third section is larger than that of the first section, so that wind can be spread from the first section with the small accommodating volume to the third section with the large accommodating volume, and the energy of sound waves can be dispersed to the third section with a larger area; as the sound needs to cover a larger area in a large space, the sound is heard to be smaller, and the noise reduction function is achieved.
本申请涉及配电设备技术领域，特别涉及一种配电房降噪装置。本申请实施例的技术方案中，该配电房降噪装置包括有配电房、配电柜、隔音层、进风管以及出风管。通过将出风管设置为第一段、第二段以及第三段，第一段的一端与出风口连通，另一端与第二段连通，第三段的一端与第二段连通。可以使得风从容纳腔内流动至第一段，再自第一段流动至第二段最后流动至第三段。并且沿第一段指向第三段的方向，第二段的截面面积呈增大趋势，第三段的容纳体积大于第一段的容纳体积，可以使得风自容纳体积小的第一段传播至容纳体积大的第三段，声波的能量会被分散到更大区域的第三段，由于声音在大空间中需要覆盖更大的面积，使得声音听起来变小，实现降噪功能。
