Shock absorber for transformer

Abstract

The invention discloses a shock absorber for a transformer. According to the technical scheme points, the shock absorber for the transformer comprises an upper shell, a lower shell and vibration reduction units. At least two sets of the vibration reduction units are arranged between the upper shell and the lower shell, and bearing connecting plates are arranged between the upper shell and the lower shell in a suspended mode. The vibration reduction units include movable plates connecting the bearing connecting plates and fixing plates fixed to the upper shell or the lower shell. Movable framesare arranged between the movable plates and the fixing plates, and guide plates are arranged on the movable frames. The guide plates and the fixing plates are separately provided with guiding columns, and the guiding columns pass through the guide plates and are slidably connected with the guide plates. The guiding columns are sleeved with damping springs for pushing the guide plates, and the fixing plates of the vibration reduction units are cyclically connected to the upper shell and the lower shell in sequence. The effects of multi-point vibration reduction and silencing are realized by using the damping springs; and a plurality of vibration reduction units are arranged in a staggered mode and receive and absorb vibration from the upper shell and the lower shell separately, thereby achieving better vibration absorption effect.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a shock absorber for transformers. Background technique [0002] During the operation of the indoor dry-type transformer (hereinafter referred to as the transformer), the vibration of the transformer body will be caused by the magnetostriction of the iron core and the electromagnetic force between the windings. The vibration of the transformer is transmitted to the foundation and the nearby ground through the transformer feet, and the vibration of the transformer placed inside the building will also cause micro-vibration of the columns and walls in the machine room. Micro-vibration will be transmitted to the upper part or the surrounding building structure through the building structure, which may induce secondary structural noise and adversely affect the indoor acoustic environment in the building.

Problems solved by technology

Micro-vibration will be transmitted to the upper part or the surrounding building structure through the building structure, which may induce secondary structural noise and adversely affect the indoor acoustic environment in the building

[0003] Installing a shock absorber under the transformer is a technical means to reduce the vibration and noise of the transformer. It has been applied in some areas, but the shock absorber currently used in the transformer is relatively weak and the vibration reduction efficiency is not high.
