Bar-type tap switch installation structure and method for embedded wind power photovoltaic box type transformer

Abstract

The invention relates to a bar-type tap switch installation structure and method for an embedded wind power photovoltaic box type transformer. A box cover fixture is arranged under the box cover of the wind power photovoltaic box type transformer. The position of the box cover fixture is corresponding to the switch fixture of a bar-type tap switch. The method comprises the steps that the installation position of the bar-type tap switch under the box cover is determined; a fixture is welded at a position corresponding to the bar-type tap switch fixture under the box cover, and a limit device is welded in the box cover fixture; a traction rope is fastened on the bearing of the bar-type tap switch; when the bar-type tap switch is installed, the traction rope is pulled to the direction of the box cover; the positioning hole of the bar-type tap switch and the circle center of the limit device reserved on the box cover are located in the same level; and the installation parts of the bar-type tap switch are installed. According to the invention, the popularization of the bar-type tap switch in all types of transformers is realized; the structure is compact and simple; the assembly of each process is convenient; the working efficiency is high; the volume of the transformer is reduced; and the manufacturing cost is reduced.

Description
