Transformer provided with telescopic external fin radiator with shock absorption pins fixedly connected with internal fins

Abstract

The present invention relates to a transformer, in particular to a transformer provided with a telescopic external fin radiator with shock absorption pins fixedly connected with internal fins. The transformer comprises a heat radiation fin provided with a flow channel and a transformer body fixed in the flow channel by matching a bolt with a nut, wherein a plurality of internal fins are arranged in the flow channel, the internal fins are integratedly connected with the heat radiation fin, and the heat radiation fin is externally provided with a plurality of external fins. The external fins comprise at least two heat radiation plates, wherein adjacent heat radiation plates are telescopically sheathed with each other, only one of the heat radiation plates is integratedly connected with the heat radiation fin, and the heat radiation fin is provided with shock absorption pins. The transformer of the present invention has the advantages that the transformer body is not easy to loose and shift, heat can be rapidly dissipated, and the heat radiation effect is adjustable, thereby solving the problems that the prior transformer is easy to shift and the heat radiation effect of a radiator is poor.

Description

technical field [0001] The invention relates to a transformer, in particular to a transformer with shock-isolation feet fixedly connected to inner fins and outer fin radiators. Background technique [0002] When the transformer is running, heat is generated, that is, the load current flows through the transformer winding to generate heat, which must be dissipated in time. Among them, the oil-immersed transformer dissipates heat by setting a radiator filled with oil. The existing oil-immersed transformer has the disadvantages of poor heat dissipation effect and easy loosening and displacement between the transformer body and the radiator when it is vibrated. Contents of the invention [0003] The invention provides a transformer with reliable connection, fast heat dissipation and adjustable heat dissipation effect, and the vibration isolation feet are fixed to the inner fin telescopic outer fin radiator, which solves the problem of poor heat dissipation effect and vibratio...
