Abstract

The invention discloses a field assembly method for a transformer. The method comprises the following steps of: 1, arranging a valve hall; 2, conveying each component of the transformer into the valve hall and assembling each component of the transformer in the valve hall; and 3, mounting a valve tower in the valve hall.

Description

technical field [0001] The invention relates to the technical field of transformer assembly in power transmission engineering, in particular to a transformer field assembly method. Background technique [0002] The research and application of UHV DC transmission technology has broad development space and application prospects. With the increase of power and voltage levels in UHVDC transmission projects, the capacity of a single converter transformer is also getting higher and higher, which makes the transportation of UHV converter transformers difficult. The main transportation difficulty of the known UHV converter transformers is the overweight and over-limit problems of the converter transformer body. The overweight problem is reflected in the transportation of the iron core, and the over limit problem is reflected in the external dimensions of the fuel tank. [0003] In the prior art, an Advanced Site Assembly (ASA) transformer is used to solve the transportation proble...
