Steering device and method used for steering converter transformer of converter station

Abstract

The invention discloses a steering device used for steering a converter transformer of a converter station. The steering device comprises two linear first tracks which are parallel to each other and two concentric arc-shaped second tracks, wherein the track gauge between the two first tracks is the same as that between the two second tracks; moreover, the two first tracks and the two second tracks are arranged crosswise in the same plane; and the circle centre of the two second tracks are positioned on the central line between the two first tracks. By using the steering device, the converter transformer can realize 180-degree steering conveniently and rapidly; the problem of steering a high-end converter transformer with high dead weight when valve halls are arranged face to face is solved; the requirement on an electrical process is met; the economical efficiency is high; moreover, the space occupation is small; and a design principle of saving the space occupation of the converter station is met. Simultaneously, the invention also discloses a method for steering the converter transformer of the converter station.

Description

technical field [0001] The invention relates to a steering device used for steering a converter transformer in a converter station and a method for steering the converter transformer in a converter station. Background technique [0002] At present, due to the heavy weight of the main large-scale equipment such as converter transformers and smoothing reactors in converter stations of various voltage levels, it is generally considered to set up straight-line transport tracks in the stations for the conversion of converter transformers during installation and maintenance. Wait for translational movement. [0003] The total weight of a single converter transformer in a general converter station is about 320 tons. The ±800kV converter station is the converter station with the highest voltage level in the world, and the weight of the converter transformer in the station is even greater. The weight of a single low-end converter transformer in a ±800kV converter station is about 24...

AI Technical Summary

Problems solved by technology

[0006] The existing technology has the following disadvantages: (1) The converter transformer needs to be unloaded and lifted from the installation trolley many times, and the work efficiency is low; (2) The steering device occupies a relatively large area, and when the upper and lower parts of the steering device rotate relative to each other, the contact surface It will generate a large sliding friction force and make it difficult to rotate. It is only suitable for smoothing reactors and other equipment with a self-weight of about 50 tons, and is not suitable for the steering of converter transformers with a large self-weight.
