Separated phase enclosed bus insulator support positioning and welding tool mould and using method

Abstract

The invention relates to the technical field of electrical equipment mechanical structures, and discloses a separated phase enclosed bus insulator support positioning and welding tool mould and a mounting method. A tool mould membrane is included, the tool mould membrane includes a square positioning plate, a T-shaped triangle spirit level is arranged at the intersection of the diagonal lines of the square positioning plate, the two ends of one diagonal line of the square positioning plate are symmetrically provided with two transverse level adjusting round head bolts, and the two ends of theother diagonal line of the square positioning plate are symmetrically provided with two height adjusting hexagon through bolts; and insulator support fixing bolts are arranged around with the intersection of the diagonal lines of the square positioning plate as the circle center and are used for connecting insulators. The tool mould is used for positioning and welding of insulator supports, positioning and welding of the insulator supports of the separated phase enclosed buses in same specifications and types can be carried out after one-time adjustment of the too mould, inclining is avoided,the positioning operation is easy and simple, the one-time yield is 100%, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of electrical equipment mechanical structures, in particular to a tooling and an installation method for positional welding of a phase-separated closed busbar insulator support. Background technique [0002] The isolated-phase closed busbar is the conductive line between the generator and the step-up transformer and common transformer circuits in large-scale thermal power, hydropower and nuclear power plants, and is an important part of the power output of power plants. At present, the positioning welding of the insulator support supported by the closed busbar conductor is based on visual inspection and simple measurement. Inaccurate positioning often leads to inconsistent height and angle tilt of the insulator support after welding. In this way, not only the positioning welding is difficult and the workload is heavy, but also the contact between the insulator and the conductor will not be in the axial posit...

Problems solved by technology

At present, the positioning welding of the insulator support supported by the closed busbar conductor is based on visual inspection and simple measurement. Inaccurate positioning often leads to inconsistent heights and angle inclinations of the insulator support after welding

In this way, not only the positioning welding is difficult and the workload is heavy, but also the contact between the insulator and the conductor will not be in the axial position after the busbar is assembled, and there will be gaps. Creepage and breakage of insulators cause potential safety hazards to the operation of the power plant, and at the same time cause a lot of waste of financial and material resources
