摘要：【中文】本发明提供一种变压器本体预应力减振装置及变压器，所述变压器包括壳体和设于所述壳体内的变压器电气本体；所述壳体的外壁平行设置数目大于1的加强筋；所述减振装置包括数目大于1的减振单元，减振单元分别设于所述加强筋表面、所述加强筋内和/或所述加强筋间的壳体外壁上；减振单元包括预应力筋、与所述预应力筋两端连接且用于固定其位置的固定件和与所述预应力筋中部连接且用于支撑其形态的支撑件。通过在变压器壳体的外壁设置刚度和质量较大的加强筋，限制了加强筋间壳体壁的振动，从而降低了噪声的产生；同时通过在变压器壳体的外壁加强筋上、加强筋内或加强筋间设置减振单元，进一步吸收消耗变压器内部产生的振动。 【EN】The invention provides a prestress vibration damper of a transformer body and a transformer, wherein the transformer comprises a shell and a transformer electric body arranged in the shell; the outer wall of the shell is provided with reinforcing ribs with the number larger than 1 in parallel; the vibration reduction device comprises vibration reduction units with the number larger than 1, and the vibration reduction units are respectively arranged on the surfaces of the reinforcing ribs, the interiors of the reinforcing ribs and/or the outer wall of the shell between the reinforcing ribs; the vibration reduction unit comprises a prestressed tendon, a fixing piece and a supporting piece, wherein the fixing piece is connected with two ends of the prestressed tendon and is used for fixing the position of the prestressed tendon, and the supporting piece is connected with the middle of the prestressed tendon and is used for supporting the shape of the prestressed tendon. The reinforcing ribs with higher rigidity and mass are arranged on the outer wall of the transformer shell, so that the vibration of the shell wall between the reinforcing ribs is limited, and the generation of noise is reduced; meanwhile, the vibration reduction units are arranged on the reinforcing ribs on the outer wall of the transformer shell, in the reinforcing ribs or between the reinforcing ribs, so that the vibration generated in the transformer is further absorbed and consumed.
