Mounting method for converter transformer valve side rising seat positioning device

Abstract

The invention discloses a converter transformer valve side rising seat positioning device and a method for mounting a converter transformer rising seat by using the device. The device comprises a box wall positioning flange fixed with a rising seat angle positioning pipe, and two ends of a central positioning rod of the rising seat are connected with the rising seat angle positioning pipe and a sleeve center analog pipe respectively and positioned pairwise through positioning structures respectively. Positioning of the rising seat is completed by utilizing the structure to adjust angles of the rising seat and a central shaft, and the rising seat is roughly positioned during the process and then welded for firm positioning. By the converter transformer valve side rising seat positioning device and the mounting method for the rising seat, positioning and mounting of the rising seat can be conveniently realized while accuracy is guaranteed, so that production cost is greatly lowered, mounting time can be saved, and production efficiency can be improved.

Description

technical field [0001] The invention relates to a valve side rising seat positioning device of a converter transformer and a method for installing the rising seat of a converter transformer using the device. Background technique [0002] The valve side of the DC converter transformer comes out from the end wall of the oil tank, and forms an oblique angle with the oil tank wall. The position and dimensional accuracy of the raised seat of the outlet device have a great influence on the outer insulation distance of the bushing head. The relative position of the two phases And the angle directly affects the external insulation distance. Therefore, the fabrication accuracy and relative position error control of the raised seat on the valve side are very critical. The method usually adopted in the industry is to make the flanges at both ends of the raised seat with a margin, and after the welding is completed, use a large-scale CNC machining center to process the raised seat as a...

Problems solved by technology

[0003] The disadvantage of this method is that after the welding of the raised seat, it must be processed on a large-scale CNC machining center, and the equipment limitation and processing cost are very high; only the manufacturing accuracy of the raised seat can be controlled, and the assembly position accuracy of the raised seat and the box wall cannot be controlled , there is no predictable and adjustable space for errors after molding and assembly
