Abstract

The utility model discloses a shock absorption device used for a transformer core. The shock absorption device used for the transformer core comprises an iron core, a clamping unit and a shock absorption mat. The shock absorption mat is arranged between the bottom of the iron core and the clamping unit, and an elastic insulating layer is arranged between the periphery of the iron core and the clamping unit. The shock absorption mat with a relatively strong buffer function is added between the iron core and the clamping unit, so that the shock absorption device used for the transformer core not only can play the buffer function for the shock generated by the iron core but also can play the isolation function for the noise produced by the iron core. Accordingly, the phenomenon that the noise is transmitted outside a transformer is effectively reduced, experience of the outside for the noise is reduced, and therefore the purpose of reducing the noise of the transformer is achieved.

Description

A kind of transformer core damping device

Technical field

The utility model belongs to the transformer technology field, relates in particular to a kind of transformer core damping device.

Background technology

Along with the enhancing of the more and more close residential block of transformer station and people's environmental protection meaning, the noise problem of transformer more and more is subject to power supply department and transformer manufacturer pays much attention to.The noise level of transformer is an important technical indicator of transformer, different transformer or use the noise level of the transformer of different occasions to require difference, the noise of transformer in normal course of operation mainly is the generation of vibration that comes from iron core, effectively reducing the noise of iron core, is the key that solves the transformer noise problem.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides a kind of transformer core damping device that can effectively reduce the transformer core noise.

In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:

A kind of transformer core damping device, it comprises iron core, folder and buffer layer pad, the buffer layer pad is arranged between iron core bottom and the folder, is provided with elastic insulating layer around the iron core and between the folder.

Described transformer core damping device, its buffer layer pad comprise upper padding plate, lower bolster and are arranged on spring between the upper and lower backing plate.

Owing to adopting technique scheme, the utlity model has following superiority:

This transformer core damping device, it utilizes sets up the buffer layer pad with stronger cushioning effect between iron core and folder, both can play cushioning effect to the vibrations of iron core, have to open the noise that iron core produces and play buffer action, effectively reduced the conduction of noise outside transformer, reduce outside impression to transformer noise, thereby reached the purpose that reduces transformer noise.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Among the figure: the 1-iron core; The 2-elastic insulating layer; The 3-folder; The 4-upper padding plate; The 5-lower bolster; The 6-spring.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1, this transformer core damping device, it comprises iron core 1, folder 3 and buffer layer pad, the buffer layer pad is arranged between iron core bottom and the folder, is provided with elastic insulating layer 2 around the iron core and between the folder.

Described buffer layer pad comprises upper padding plate 4, lower bolster 5 and is arranged on spring 6 between the upper and lower backing plate.

This damping device plays effectively cushioning effect by being arranged on iron core elastic insulating layer and buffer layer pad all around to the vibrations that produce in the transformer course of work in use, has prolonged the useful life of transformer.
