Abstract

The utility model discloses a once conducting bar anti-rotating structure which comprises a ceramic sleeve, a once conducting bar which is placed in the ceramic sleeve, and a once conducting rod which penetrates into the ceramic sleeve and is connected with the upper end of the once conducting bar through a fastener, wherein a positioning groove is formed in a position, corresponding to the upper end of the once conducting bar, of the inner portion of the ceramic sleeve, and the upper end of the once conducting bar is placed in the positioning groove. When used for being connected with a mutual inductor line bank, the once conducting bar anti-rotating structure has the advantages of being simple and reliable in structure and convenient to install, and enabling rotation, deformation and breaking of the once conducting bar not to occur due to the fact that the positioning groove is formed between the once conducting bar and the ceramic sleeve when a once conducting bar is fastened and external twisting force is overlarge.

Primary conductive is arranged anti-rotation structure

Technical field

The utility model relates to a kind of mounting structure of current transformer, relates in particular to a kind of primary conductive and arranges anti-rotation structure.

Background technology

Primary conductive bar and primary conductive row are the most important parts of instrument transformer control of product quality as the core component of current transformer, so whether its version is rationalized particularly crucial.Mainly there are the following problems for some present structures: 1. assembling is inconvenient; 2. easily generation once connects the living rotation of discharge in the assembling process, distortion fractures; 3. be connected and fixed more loosening.

The utility model content

The utility model proposes a kind of primary conductive and arrange anti-rotation structure, it can overcome deficiency of the prior art effectively, and it is easy to assembly, and primary conductive row can not be out of shape, reverses or fracture in the assembling process, and is reliable and stable after the assembling.

The technical solution of the utility model is achieved in that a kind of primary conductive arranges anti-rotation structure, the primary conductive row who comprise insulator, is positioned at insulator and the primary conductive bar that is connected insulator and upper end that primary conductive is arranged and is connected by securing member, part corresponding with primary conductive row's upper end in the described insulator is provided with location notch, and described primary conductive row's upper end is positioned at this location notch.

As preferably, described primary conductive bar arranges two draw-in grooves with the part that primary conductive row is connected along its radial symmetric, and the upper end that described primary conductive is arranged offers the U-shaped groove that cooperates with two draw-in grooves, and the part that the primary conductive bar is offered draw-in groove is fastened in the U-shaped groove.

As preferably, described securing member is nuts and washers.

As preferably, described primary conductive bar is thread segment near the end of draw-in groove, and the part that the primary conductive bar passes insulator is the polished rod section, and the part that is positioned at the insulator outside also is thread segment, and is provided with a plurality of nuts and pad in this section.

As preferably, the both sides of described primary conductive row's upper end respectively arrange a packing ring, and described gasket sleeve is located on the primary conductive bar, and by the nut that is spun on the primary conductive bar primary conductive row are pressed on the insulator.

The beneficial effects of the utility model are: this structure applications connects the following advantage that mainly contains in instrument transformer line row: 1. simple and reliable for structure, easy for installation; 2. between primary conductive row and the insulator location notch is arranged, during fastening primary conductive bar, when outer lashing force is excessive, can cause primary conductive row rotation, be out of shape or fracture; 3. when tightening the primary conductive bar, the primary conductive bar can not produce rotation because of the impact of outside torsion.
