Problems solved by technology

Under the influence of this long-term temperature fluctuation, the wire coil wound on the winding frame will be deformed due to its own thermal expansion and contraction. When the heating conditions of different parts of the coil are different, irregular deformation will occur, which is easy Causes excessive twisting of wire coils

Abstract

The invention discloses an improved transformer winding rack structure. The improved transformer winding rack structure comprises a rack body, wherein a primary winding region and a secondary winding region are respectively arranged at two ends of the rack body, coils are respectively arranged on the primary winding region and the secondary winding region, each coil comprises a plurality of annular winding plates which are concentrically arranged, second through holes are formed in the annular winding plates, a plurality of baffle plates are arranged on the annular winding plates, a first cavity is formed in the annular winding plate between two adjacent baffle plates along an axial direction of the annular winding plate, a second cavity is formed in each baffle plate and communicates with the first cavity, two first support rods are symmetrically arranged in the second cavity and are respectively hinged with second support rods in the first cavities at two sides, third support rods are hinged with side walls of the first support rods, and an arc support plate is fixedly connected with one end, arranged at an outer side of the baffle plate, of each third support rod. By the improved transformer winding rack structure, the defect of the prior art can be improved, and the protection effect of a winding coil is improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an improved winding frame structure of a transformer. Background technique [0002] The transformer winding frame is the main structural part of the transformer, which provides winding space for the wire coil in the transformer and fixes the iron core in the transformer. During the working process of the transformer, with the change of the transformer load, the temperature fluctuation inside the transformer will also increase. Under the influence of this long-term temperature fluctuation, the wire coil wound on the winding frame will be deformed due to its own thermal expansion and contraction. When the heating conditions of different parts of the coil are different, irregular deformation will occur, which is easy Causes excessive twisting of wire coils. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improv...
