Converter transformer valve side sleeve auxiliary installation device

Abstract

The invention discloses a converter transformer valve side sleeve auxiliary installation device, which comprises a vehicle body and a supporting frame arranged on the upper portion of the vehicle body, supporting rods are arranged on the two sides of one end of the supporting frame, and the supporting frame is obliquely arranged on the vehicle body through the supporting rods; first pipe frames are arranged at the two ends of the supporting frame and comprise first box bodies, clamping arms are arranged on the two sides of the upper portions of the first box bodies, the middles of the clamping arms are bent to be of a V-shaped structure, stand columns are hinged to the middles of the clamping arms, and the lower ends of the stand columns are fixedly connected with the first box bodies; through holes are arranged at the middle of the first box bodies, first connecting rods are slidably connected into the through holes, supporting plates are arranged at the upper ends of the first connecting rods and are of an arc-shaped structure, and arc-shaped grooves matched with the supporting plates are arranged at the upper portions of the box bodies. When a valve side sleeve is installed, the sleeve is loaded on the supporting frame outside a hall, the valve side sleeve is clamped on the supporting frame through the first pipe frames, then the auxiliary installation device is moved into the valve hall to be installed, and the installation cost and difficulty of the valve side sleeve are reduced.

Description

technical field [0001] The invention belongs to the technical field of converter converter installation equipment, and in particular relates to a converter converter valve side bushing auxiliary installation device. Background technique [0002] In the HVDC power transmission system, the converter transformer (hereinafter referred to as the converter transformer) is one of the most important devices. This is due to its location at the core of alternating current and direct current conversion, as well as the complexity of equipment manufacturing technology and the expensive equipment. The converter transformer is similar to the general transformer in terms of working principle and structure, the main difference is that the valve side winding bears AC voltage and DC voltage at the same time. The winding connected to the AC bus of the converter station connected to the AC power grid is called the grid side winding, the winding connected to the converter valve is called the val...

AI Technical Summary

Problems solved by technology

[0004]Currently, the installation of valve side bushings mostly adopts the form of hoisting. Due to the heavy weight and long length of the valve side bushings, manual hoisting generally requires the cooperation of multiple cranes The installation cost of the valve side bushing is high and the installation efficiency is low; since the valve side bushing is mostly arranged inside the valve hall, it is difficult for the crane to construct inside the valve hall; in addition, the valve side bushing is generally inclined Installation, installation is difficult,
