Technical Field

The utility model relates to a box-type substation technical field specifically is a box-type substation of making an uproar falls.

Background

The box-type transformer substation is also called a pre-installed transformer substation or a pre-installed transformer substation, is compact distribution equipment with high-voltage switch equipment, a distribution transformer and a low-voltage distribution device which are arranged into a whole according to a certain wiring scheme, namely, the functions of transformer voltage reduction, low-voltage distribution and the like are organically combined together and are installed in a steel box body, and the box-type transformer substation is particularly suitable for urban network construction and transformation.

The existing box-type substation can generate low-frequency vibration during working, so that not only can resonance of the box body be easily caused and noise be generated, but also the noise is close to the natural frequency of a human body, so that the human body can resonate and generate chronic damage to the human body, and diseases such as neurasthenia, insomnia and the like can be caused when the human body is in a low-frequency noise environment for a long time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a box-type substation of making an uproar falls to solve the transformer substation noise pollution problem that proposes in the background art.

In order to achieve the above object, the present invention provides the following solutions: the utility model provides a box-type substation of making an uproar falls, includes the box, the box comprises top cap, curb plate, bottom plate, backplate, chamber door, its characterized in that: the inside 2 baffles that are equipped with of box, the baffle will the box divide into hyperbaric chamber, vary voltage room, low-pressure chamber, the top cap the curb plate the bottom plate the backplate the chamber door the baffle is hollow structure, and inside uses the sound shock-absorbing material of inhaling to fill, the bottom plate below is equipped with the shock pad, backplate upper portion is equipped with 3 thermovents, the curb plate lower part is equipped with the vent.

Preferably, each part of the box body is fixedly connected through a bolt.

Preferably, the sound absorption and shock absorption material is XPE foam, and the filling thickness is 5-10 mm.

Preferably, the shock pad is made of XPE foam or rubber, and the thickness is between 10 and 20 mm.

Preferably, the lower part of the partition board is provided with a through hole.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the low frequency vibrations that the transformer substation during operation produced on the one hand propagates through the form of air with the noise, on the other hand arouses box resonance, produce other noises, the utility model discloses an inhale the sound damping material and be XPE bubble cotton, have excellent sound of inhaling, the shock attenuation effect, and differ greatly with the metal natural frequency of preparation box, can effective noise absorption and eliminate the resonance of box, when the vibrations that the transformer substation produced transmit the box, the sound wave is through the multiple reflection in the cotton inside cavity of XPE bubble, most is absorbed, cushion the mechanical shock of box simultaneously, reduce vibration intensity, reach the effect of eliminating most noises.

2. The shock pad of bottom half separates box and base, has effectively prevented on the vibrations of box transmit the base, prevents to form resonance between box and the base, has further reduced the production of noise.

3. The utility model discloses an inhale the inside of sound shock-absorbing material packing at each part of box, compare in setting up the acoustic celotex board in the box is inside, the utility model discloses do not influence the box inner space, most acoustic material that adopts among the prior art all burns easily, and the utility model discloses stopped the possibility of acoustic material and the interior electrified object contact of box, the security is high.
