Prefabricated transformer substation noise reduction device

Abstract

The invention discloses a prefabricated substation noise reduction device, and relates to the technical field of substation noise reduction. The device comprises a shell and a noise reduction mechanism. A buffer base and a noise reduction mechanism are fixedly connected to the interior of the shell; the noise reduction mechanism comprises a first-stage buffer plate, a second-stage buffer plate, a third-stage buffer plate and a damping device; a plurality of sets of damping devices arranged in parallel are fixedly connected between the first-stage buffer plate and the second-stage buffer plate, a plurality of sets of parallel damping devices are fixedly connected between the second-stage buffer plate and the third-stage buffer plate, and the damping devices are perpendicular to the damping devices between the first-stage buffer plate and the second-stage buffer plate. The damping device comprises a track groove, a track block and a buffering assembly. The noise reduction mechanism of the device can achieve the functions of weakening vibration of the transformer and absorbing vibration energy, also has the effect of blocking underground noise conduction, replaces a traditional base, and has the effect of saving space.

Description

technical field [0001] The invention relates to the technical field of substation noise reduction, in particular to a prefabricated substation noise reduction device. Background technique [0002] A substation is a kind of transformer equipment used to convert a large-scale high-voltage circuit into a small-scale voltage circuit. Early Baineng power stations often used earthen substations. Now commonly used substations are mainly prefabricated. The required step-down and low-voltage power distribution functions are assembled together, connected using pre-arranged wiring methods, prefabricated in the factory, and become a complete device, installed in a waterproof and dustproof steel closed structure , has good mobility and is easy to install, and is now widely used. [0003] Prefabricated substations are used for voltage conversion, so they are often installed in densely populated areas, but the equipment required for voltage conversion will generate strong magnetic force w...

AI Technical Summary

Problems solved by technology

[0003]Prefabricated substations are used for voltage conversion, so they are often installed in densely populated areas. The metal structure of the substation produces a certain degree of disturbance, which makes the equipment easy to generate large noise during use. The noise of the substation will have a negative impact on the daily life of the surrounding users. Therefore, it is necessary to reduce the noise of the substation.

[0004]The substation installed with the internal sound insulation layer still cannot effectively solve the noise problem. Loud noise, even if a shock-absorbing structure is installed inside, this noise can also be transmitted to the outside of the transformer through the solid connection between the transformer and the ground
