Abstract
The utility model relates to a mounting torsion resistance device of an explosion-proof wall bushing, in particular to the mounting torsion resistance device of a mine explosion-proof mobile substation wall bushing and a wall bushing guide rod. The mounting torsion resistance device of the explosion-proof wall bushing is composed of the mine explosion-proof mobile substation wall bushing, the wall bushing guide rod and wiring copper sheets. The wiring copper sheets are connected with the wall bushing through the wall bushing guide rod, and two ends of the wall bushing guide rod are fastened by nuts. The mounting torsion resistance device of the explosion-proof wall bushing is characterized in that the middle end of the wall bushing guide rod is manufactured to be in an hexagonal shape, and the inner portion of the wall bushing is also manufactured to be in an hexagonal hole shape. When the wall bushing guide rod is connected with the wall bushing, the inner portion of the wall bushing is clamped tightly and fixed. Due to the above technical scheme, the mounting torsion resistance device of the explosion-proof wall bushing has the advantages that when the wall bushing guide rod is fastened by the nuts, the wall bushing guide rod can not be twisted so that the wiring copper sheets are deformed, and accordingly an electric clearance of the wiring copper sheets is too small to discharge electricity. The mounting torsion resistance device of the explosion-proof wall bushing is simple in structure and easy to manufacture.
Description
Technical field
The utility model relates to a kind of anti-torsion device, and particularly a kind of flame proof wall bushing is installed the anti-torsion device.
Background technology
At present, the main use of flameproof mining mobile transformer substation (flameproof dry type transformer) has in the explosive gas atmosphere under coal mine, it is the confession that a kind of underground mine use has flameproof enclosure, converting equipment, its three-phase output end (or input) links to each other with flame proof wall bushing in the terminal box by the wall bushing guide rod in that the terminal box of flameproof enclosure is inner, in the overall installation stage of transformer, when fastening nuts is carried out in the wall bushing outside, very easily causing wearing the wall guide rod reverses, thereby make the copper lug distortion, affect the electric clearance between the three-phase copper lug, hidden danger causes the accident, when flame-proof type mobile substation interiors of products has keeped in repair overall installation in addition, owing to can't see inner case clearly, also easily cause secondary failure hidden danger.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of flame proof wall bushing that the anti-torsion device is installed, cause wearing the wall guide rod in the time of preventing the installation of flame proof wall bushing and reverse and cause the copper lug distortion.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model is comprised of copper lug wall bushing guide rod, flame proof wall bushing, it is characterized in that: copper lug links to each other with wall bushing by the wall bushing guide rod, wall bushing guide rod shaft and wall bushing inside are hexgonal structure, and there is nut at wall bushing guide rod two ends.
Because adopt technique scheme, advantage and good effect that the utility model has are: carrying out the wall bushing guide rod with nut when fastening, the wall bushing guide rod can not reverse, and copper lug is indeformable, and is simple in structure, is easy to make.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
