The damping structure of this patent is arranged at the bottom of the transformer. Although it has a certain damping effect, it will change the basic dynamic characteristics such as the natural frequency of the transformer, and the process of energy dissipation and damping will still cause large vibrations of the transformer box. , so it is still easy to cause damage to the transformer bushing assembly

The invention relates to a transformer with an energy dissipation damping function. The transformer comprises a transformer box body (2), an energy dissipation damping system (6) and a transformer oil conservator (1), the energy dissipation damping system (6) is fixedly arranged at the top end of the transformer box body (2), and the transformer oil conservator (1) is fixed on the energy dissipation damping system and is combined with the energy dissipation damping system to form a tuned mass damper with the transformer oil conservator (1) as a mass block and the energy dissipation damping system (6) as a tuning device. Compared with the prior art, the transformer provided by the invention has the advantages of simple structure, good energy dissipation damping effect, and no influence on the performance of the transformer, and the like.
Description
technical field [0001] The invention relates to the technical field of substation equipment, in particular to a transformer with the function of energy dissipation and shock absorption. Background technique [0002] With the development of my country's power transmission and transformation projects in the direction of high voltage, ultra-high voltage and ultra-high voltage, a large number of key power transformation equipment - large power transformers and converter transformers - are equipped in AC substations and DC converter stations. These large transformers have large volume and quality, high cost, and a large number of bushings are installed on the transformers. In previous earthquakes, due to the power amplification of the transformer box, the transformer bushings were seriously damaged, resulting in the shutdown of substations and large-scale power outages in the power grid. For a typical transformer structure see figure 1 As shown, it includes a transformer box 1,...
