Description

Technical Field

[0001] The utility model relates to the technical field of conductive rod processing equipment, and more specifically, particularly relates to a conductive rod outlet end positioning tool for GIS. Background Art

[0002] Currently, the GIS conductive poles are relatively long, usually more than 5 meters. During assembly, they extend from one end of the transformer barrel to the other and will naturally sag due to their own gravity, requiring workers to operate manually, which affects installation efficiency. In addition, the tail joint requires the three conductive pole center joint dimension tolerance to be only ±1mm. Previously, manual adjustment and ruler measurement were used for installation, which is inefficient and cannot guarantee accuracy. Utility Model Content

Both ends of the positioning cylinder are open, and a rubber protective sleeve is fixedly provided on the upper inner part of the positioning cylinder.

[0005] Preferably, the connecting line between the circular opening axes of the bottom plate and the surface of the protruding portion forms an isosceles triangle shape.
