Abstract
The utility model relates to transformer station's technical field, particularly relates to a kind of box-type substation denoising structure.This structure comprises the transformer in casing and casing, and roof box is equipped with blower fan, and outside blower fan, air inlet is connected with a blast pipe, blast pipe sound absorbent of inner liner; Described casing surrounding is provided with safe fence, every Partial security fence includes above base, sound-absorbing wall and sound-absorbing wall, to casing and rolls oblique acoustic board, higher than casing top bottom acoustic board, posts reflecting strips outside sound-absorbing wall, and being provided with warning sign, one of them sound-absorbing wall is provided with access door.The utility model sets up sound-absorbing or sound arrester by becoming outside at air inlet and case, stops the noise pollution environment in case change further, improves noise-reduction effect.Meanwhile, by becoming the improvement of surrounding fence to case, make it play warning function, as a kind of sound-insulating structure, noise reduction can also be played.
Description
Technical field
The utility model relates to transformer station's technical field, particularly relates to a kind of box-type substation denoising structure.
Background technology
Box-type substation (becoming hereinafter referred to as case) is a kind of conventional controller switching equipment, and the electricity consumption concentration zones such as residential block, factory all needs to be equipped with box-type substation.Because transformer station is built with the equipment such as high-and low-voltage switch equipment, distribution transformer, these equipment operationally can make a noise, especially transformer, and the noise of generation is very big.To the transformer station being positioned at residential block, its noise has a strong impact on the life of resident.Existing case change also takes certain noise reduction measure, but be generally that soundproof box is set for case becomes, like this can from the suitable blocking noise of surrounding outwardly Environmental diffusion, but case becomes generally has the ventilation heat abstractors such as blower fan, from exhaust outlet, the noise in case change can be passed to external environment while the outside air draft of blower fan.Meanwhile, the operating noise becoming interior equipment due to case is too large, and the noise reduction singly having the sound insulation of case change casing to reach is unsatisfactory.For preventing idler from becoming close to case, cause personal injury, case becomes outer generally has fence, therefore, can consider to improve fence, as the further noise reduction measure of the one become case.
Summary of the invention
For solving the problem, the utility model provides a kind of box-type substation denoising structure, by blower fan noise reduction and external noise reduction two aspects, reduces the noise pollution of transformer station further.
Concrete scheme of the present utility model is: a kind of box-type substation denoising structure, comprises the transformer in casing and casing, roof box is equipped with blower fan, and outside blower fan, air inlet is connected with a blast pipe, blast pipe sound absorbent of inner liner; Described casing surrounding is provided with safe fence, every Partial security fence includes above base, sound-absorbing wall and sound-absorbing wall, to casing and rolls oblique acoustic board, higher than casing top bottom acoustic board, posts reflecting strips outside sound-absorbing wall, and being provided with warning sign, one of them sound-absorbing wall is provided with access door.By being provided with the blast pipe of sound-absorbing liner at air inlet, the noise absorption of discharging from air inlet can be fallen, go back the noise that Absorbable rod blower fan produces simultaneously, decrease the diffusion of noise from here.Meanwhile, fence case being become surrounding changes sound-absorbing wall into, and is become by the inside coated case of acoustic board, makes noise inner by reflection-absorption at fence, prevents outside diffuse pollution environment.Sound-absorbing wall establishes reflecting strips, can, the passerby of night prompting approach, prevent from bumping against the railing.In addition, arrange warning sign, warning passerby can not enter.
Preferably, described sound-absorbing wall is the body of wall being provided with waveform noise reduction layer.
Further, described transformer bottom is provided with damping cushion, and vibrations when preventing transformer from running to outdiffusion, cause vibrating noise to pollute by ground.
Further, described damping cushion is provided with ventilation hole, to ensure the ventilation and heat of transformer.
For preventing the operating noise of transformer to outdiffusion, be provided with blimp outside described transformer, blimp top is provided with louvre.Hot-air is upwards carried from louvre, ensures result of ventilating heat dissipation.
Further, sound panel is established in described wall box and top board.
Preferably, the sound-absorbing material of exhaust duct liner is porous sound absorbing material.
The utility model sets up sound-absorbing or sound arrester by becoming outside at air inlet and case, stops the noise pollution environment in case change further, improves noise-reduction effect.Meanwhile, by becoming the improvement of surrounding fence to case, make it play warning function, as a kind of sound-insulating structure, noise reduction can also be played.
