Abstract

The invention discloses a heat preservation method and system for a converter transformer. The heat preservation system of the converter transformer comprises a converter transformer body; the outer surface of the converter transformer body is coated with the double-layer thermal insulation material; wherein the double-layer thermal insulation material comprises first fireproof thermal insulation cotton and second fireproof thermal insulation cotton; the outer surface of the converter transformer body is coated with the first fireproof thermal insulation cotton; and the sealed heat preservation shed is packaged on the outer side of the fireproof heat preservation cotton. According to the technical scheme, the problem that in the prior art, under the condition that the external environment temperature is low, the outlet oil temperature of the converter transformer body cannot reach the specified technical index easily is solved.

Description

technical field [0001] The invention relates to the technical field of DC power transmission, in particular to a heat preservation method and system for a converter transformer. Background technique [0002] The converter transformer is the core equipment of the DC power transmission project. Together with the converter valve, it constitutes the "heart" of the converter station - the converter station. The main function of the converter transformer is to convert 750 kV alternating current into ±800 kV direct current, so as to realize long-distance, large-scale, high-efficiency and low-loss transmission of clean energy. [0003] As one of the most important equipment in a converter station, the converter transformer is characterized by large volume, heavy tonnage, high requirements for the surrounding environment, many installation processes, and great difficulty in positioning; these characteristics lead to the entire installation process of the converter transformer. It is...
