Transformer body positioning device applied to on-load voltage regulating transformer

Abstract

The invention discloses a transformer body positioning device applied to an on-load voltage regulating transformer. Clamping plates are arranged on an oil tank cover, the clamping plates are directly fixed to four pull screw rods on the upper side of the oil tank cover through connecting plates, and the upper portion of a transformer body is positioned in the mode that limiting nuts are used for tightening and limiting; and the number of fixed parts on the upper portion of the transformer body is small, raw material consumption can be reduced, the mass of the transformer is reduced, and the space of a transformer body is saved. The transformer body can be limited in the horizontal direction through the matching of limiting plates on the bottom plate of the oil tank at the lower part of the transformer, connecting blocks, positioning screw rods and positioning nuts, and therefore, the phenomenon that the whole transformer body is easy to displace under other external factors such as transportation can be prevented, the compactness of a transformer structure is ensured, and normal installation and use of the transformer are ensured.

Description

technical field [0001] The present application relates to the application field of transformers, in particular to a device body positioning device applied to on-load voltage regulating transformers. Background technique [0002] With the rise of new energy and the application of high-performance electrical steel, in the field of power products, more and more attention is paid to the lightweight and stability of products, and high-energy-consuming transformer products are replaced by new series products. At the same time, the state has issued relevant policies. In order to maintain the excessive use of cultivated land, the use of land will be considered in the early stage of the construction of each substation. All electrical layouts will gradually increase the size, light weight, energy saving, and intelligence of equipment without affecting the safety of use. Incorporated into the required range, so 35kV on-load tap changer will be the mainstream product form in this voltag...

AI Technical Summary

Problems solved by technology

[0004] This application provides a body positioning device applied to on-load tap changer transformers, which solves the problem of heavy transformer weight, low space utilization of the body and other external problems such as transportation caused by the traditional transformer body positioning method in the prior art. The overall body is prone to displacement under the factors, which affects the installation and use of the transformer
