Split type opening and closing current conductor

Abstract

The invention discloses a split type opening and closing current conductor which comprises a contact assembly, a current conducting rod assembly and a current conducting connecting assembly, wherein one end of the current conducting rod assembly is detachably connected with the current conducting connecting assembly, and the other end of the current conducting rod assembly is detachably connectedwith a contact assembly; the current conducting rod assembly comprises a first current conducting rod, a second current conducting rod and a current conducting fixer; one end of the second current conducting rod penetrates into the first current conducting rod; the current conducting fixer is fixed on the outer side of the joint of the first current conducting rod and the second current conductingrod; the current conducting connecting assembly comprises a connecting flange and an end connecting piece; the connecting flange is fixedly connected with the end connecting piece; one end of the first current conducting rod penetrates into the end connecting piece; and the connecting fixer is fixed outside the joint of the first conducting rod and the end connecting piece. The split type openingand closing current conductor solves the transportation problem, can be installed on site, and solves the problem that the length of the opening and closing current conductor is uncertain due to thedeviation of the actual height and the theoretical height of the jumper.

Description

technical field [0001] The invention relates to the technical field of overhead power transmission lines, in particular to a split-type opening and closing conductor. Background technique [0002] In the cold winter, some transmission lines in southern my country are prone to icing. Uneven icing on conductors and ground wires will cause the tower to tilt or bend. When the design capacity is exceeded, conductors and ground wires will break, hardware will fall off, etc., which will seriously cause the tower to collapse. The overhead ground wire is not like a wire that can resist partial freezing through the heat generated by the load current, and its ice thickness is generally far greater than that of the transmission wire. [0003] Since 2013, according to different voltage levels of transmission lines, the project team has developed side-closed and top-closed ground wire melting automatic wiring devices, and the type of opening and closing conductors has also been newly des...

AI Technical Summary

Problems solved by technology

With the increasing use of ground wire automatic wiring devices for melting ice, the types of towers for installation devices are gradually increasing. In ±800kV UHV power transmission projects, the distance between the squirrel-cage hard jumper and the cross-arm of the iron tower is usually more than 10 meters , resulting in a length of about 10 meters for the opening and closing conductor, the original integral opening and closing conductor is no longer applicable, and a new split type opening and closing conductor needs to be designed
