Matched grooves are formed in a base of the steel rail and a top cover of the steel rail. The damper springs are embedded in the grooves. The shock absorption layer is laid on a top cover of the steel rail. The transformer base is fixedly arranged above the shock absorption layer. The transformer vibration isolation and noise reduction device has the advantages that the springs and a rubber pad are arranged, dual vibration isolation and noise reduction are achieved, high-frequency and low-frequency vibration and solid sound transmission are greatly reduced, the phenomenon that echo resonance occurs between floors of a transformer substation is avoided, mechanical vibration of the transformer is reduced, the service life of the device is prolonged, and meanwhile the noise reduction effect of the underground transformer substation meets the environmental requirement.
Description
Technical field
The utility model relates to a kind of denoising device; Particularly relate to a kind of transformer vibration insulation and noise reduction device that is applicable to.
Background technology
Traditional transformer construction technology is that the pedestal that transformer is carried is directly placed in flooring or concrete foundation, without any vibration insulation and noise reduction measure.In the time that transformer moves, noise produces echo resonance and solid-borne sound transmission at underground substation floor gap, causes noise huge, and noise pollution has a strong impact on surrounding resident life and the operator on duty's of transformer station normal work.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of transformer vibration insulation and noise reduction device simple in structure, easy for installation is provided.
The technical scheme that the utility model adopts is: a kind of transformer vibration insulation and noise reduction device, comprises rail, shock-absorbing spring, buffer layer and transformer base; On the substrate of described rail and top cover, be formed with suitable groove, in described groove, be inlaid with shock-absorbing spring; On the top cover of described rail, be equipped with buffer layer, above described buffer layer, be installed with transformer base.
Described rail has two at least, and rail is parallel with transformer base or vertical.
When described rail is parallel with transformer base, be formed with 5 suitable equidistant grooves on the substrate of rail 1 and top cover, shock-absorbing spring is fixed on the bottom of rail by connecting bolt, and material is stainless steel, and diameter is 200mm.
When described rail is vertical with transformer base, be formed with suitable and equally distributed three pairs of grooves on the substrate of rail and top cover, center, every pair of top cover top is equipped with buffer layer.
Described buffer layer is rubber blanket, and the thickness of rubber blanket is 20mm.
The distance on transformer bottom surface and ground is more than or equal to 150 mm.
The beneficial effects of the utility model are: due to spring and rubber blanket being installed, realize dual vibration isolation sound insulation, high and low frequency vibration and solid-borne sound transmission are significantly reduced, avoid transformer station's floor gap to produce the phenomenon of echo resonance, owing to having reduced the mechanical shock of transformer, also extended the useful life of equipment, also make underground substation reducing noise effect meet environmental requirement simultaneously simultaneously.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model transformer vibration insulation and noise reduction device is arranged in power distribution room, comprises rail 1, shock-absorbing spring 2, buffer layer 3 and transformer base 4; Described rail 1 has two at least, and operating personnel arrange the basic built-in fitting corresponding with rail 1 on transformer station ground, in order to the foundation of fixing damping device; On the substrate of described rail 1 and top cover, be formed with suitable groove, in described groove, be inlaid with the shock-absorbing spring 2 of anti-shearing damp, it is worthy of note, it is in full accord that the elastic strength coefficient k (being Gini coefficient) of damping spring parts must keep, to guarantee that substation transformer and noise reduction pedestal entirety are subject to equilibrium of forces, even; The frequency producing when self resonance frequency of damping spring parts will stand up to move with transformer keeps different, can not cause resonance with damping spring parts self frequency overlap when guaranteeing transformer work, produces larger noise; Shock-absorbing spring 2 is fixed on the bottom of rail 1 by connecting bolt, material is stainless steel, and diameter is 200mm, and the magnitude setting of shock-absorbing spring is answered transformer situation and determined; On the top cover of described rail 1, be equipped with buffer layer 3, described buffer layer 3 is rubber blanket, and the thickness of rubber blanket is 20mm, and rubber blanket, in playing shock absorbing effect, agrees with silastic-layer top transformer bracket and noise reduction pedestal more tight, firm; Above described buffer layer 3, be installed with transformer base 4, when the distance on transformer bottom surface and ground is more than or equal to 150 mm, can effectively reduce mechanical oscillation.
The utility model is due to spring and rubber blanket being installed, realize dual vibration isolation sound insulation, high and low frequency vibration and solid-borne sound transmission are significantly reduced, avoid transformer station's floor gap to produce the phenomenon of echo resonance, owing to having reduced the mechanical shock of transformer, realize the function of underground substation noise reduction, also extended the useful life of equipment simultaneously, meet transformer substation construction and operation maintenance requirements of one's work.
