The invention relates to a bracket capable of manually adjusting a feed-through type current transformer aperture. The bracket comprises a transformer ring frame, adjustment blocks, adjustment handles, positioning pin holes and positioning pins. The transformer ring frame has a plate type circular ring structure; four radial straight slots are distributed at the middle part of the side wall of thetransformer ring frame uniformly; an adjustment block is embedded in each straight slot in a sliding manner; and the adjustment handles are fixedly installed at the middle parts of the adjustment blocks and extend out of outer side of the transformer ring frame in a radial direction. Four positioning pin holes are distributed in the front panel of the transformer ring frame uniformly and annularly by corresponding to the straight slots; and the positioning pins are installed in the positioning pin holes. After the bracket is applied, the great convenience is brought for the laboratory personnel in work; one of factors causing the error in testing is reduced effectively; and the work efficiency is improved substantially.
Description
technical field [0001] The invention belongs to the technical field of electric engineering, in particular to a bracket for manually adjusting the aperture of a through-core current transformer. Background technique [0002] In the daily transformer test work, especially the detection of the feedthrough current transformer, the primary conductor must pass through the central aperture of the transformer, and the deviation between the position of the primary conductor and the central axis will affect the accuracy of the error data of the transformer, resulting in qualified Therefore, in order to solve this problem, a bracket that manually adjusts the size of the through-hole aperture is designed to solve the problem of reducing the error factor. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, and provide a bracket for manually adjusting the aperture of a feed-through current transformer. [0004] The...
