Protective device for transformer and oil-immersed transformer

The utility model provides a protective device for a transformer and an oil-immersed transformer. The protective device for the transformer comprises a protective structure arranged on the periphery of radiating fins, and the protective structure is provided with a damping buffer connecting structure used for being fixedly connected with a transformer body and a damper used for being in buffer contact with the radiating fins. According to the protection device for the transformer, the technical problems that in the prior art, a damping assembly of a cooling fin is complex to install, and a transformer body lacks shock resistance protection are effectively solved. 本实用新型提供一种变压器用防护装置及油浸式变压器，变压器用防护装置包括用于设在散热翅片外围的防护结构防护结构上设有用于与变压器本体连接固定的阻尼缓冲连接结构和用于与散热翅片缓冲接触的阻尼器。本实用新型提供的变压器用防护装置有效解决了现有技术中散热翅片的减震组件安装复杂以及变压器本体缺少抗冲击防护的技术问题。
