Embodiment

[0047] Such as Figure 1 to Figure 10 A noise reduction device is shown, which can reduce the noise of oil-immersed reactors such as oil-immersed reactors, and specifically includes a support frame, a sound-absorbing and insulating component 3 and an anti-vibration component. Among them such as Figure 1 to Figure 3 As shown, the oil-immersed reactor includes a reactor body 61, a reactor oil tank 62, a reactor heat sink 63, and a reactor riser 64. The reactor body 61 is located in the reactor oil tank 62, and the reactor heat sink 63 is fixed on The reactor oil tank 62 and the reactor riser 64 are fixed on the top of the reactor oil tank 62 .

[0048] The support frame in this embodiment includes such as Figure 4 The top support frame 1 and the peripheral support frame shown are enclosed and covered by the top support frame 1 and the peripheral support frame outside the oil-immersed reactor. Wherein the support frame is made of square steel, preferably, the wall thickness ...

Abstract

The invention discloses a noise reduction device, which comprises a supporting frame, a sound absorption and insulation assembly and an anti-vibration assembly, wherein the supporting frame comprisesa top supporting frame and a peripheral supporting frame, the peripheral supporting frame comprises a plurality of peripheral cross beams and a plurality of peripheral stand columns, the peripheral stand columns are fixed on a foundation plane, the peripheral cross beams are connected with the peripheral stand columns in a crossed mode, and the peripheral cross beams and / or the peripheral stand columns are connected with the top supporting frame; the anti-vibration assembly comprises a first anti-vibration piece and a second anti-vibration piece, the first anti-vibration piece is arranged at the cross connection position of the peripheral cross beam and the peripheral stand column in a spaced mode, and the second anti-vibration piece is arranged at the cross connection position of the topsupporting frame and the peripheral supporting frame in a spaced mode. The first anti-vibration piece can prevent the peripheral stand column from transmitting vibration to the peripheral cross beam,and the second anti-vibration piece can prevent the peripheral supporting frame from transmitting vibration to the top supporting frame and the sound absorption and insulation assembly, so that the situation that secondary noise is generated due to vibration is avoided.

Description

technical field [0001] The invention relates to the technical field of noise pollution protection, in particular to a noise reduction device. Background technique [0002] With the maturity of UHV transmission technology, my country's UHV AC and DC projects have entered a new stage of large-scale construction. At the same time as the UHV project construction, my country has also made major breakthroughs in the localization of UHV power transmission and transformation core technologies and equipment, but there are still shortcomings to be improved in terms of environmental coordination of electrical equipment. Environmental protection issues represented by audible noise are bringing environmental pressures that cannot be ignored to the power grid. Due to a series of reasons such as manufacturing process differences, equipment aging, and long-term operation, the noise pollution problem of UHV substation equipment has become increasingly prominent, especially UHV shunt reactors...
