Abstract

The invention provides a lifting method for a transformer, and relates to the field of installation of transformers and associated equipment. The lifting process of the transformer mainly comprises the following steps of: selecting steel channel and tools such as a hoisting machine according to the quality of the transformer; selecting an appropriate stress point; and lifting the transformer. Compared with general transformer lifting methods, the working efficiency can be effectively improved, and the cost is reduced through the method of the invention.

Description

technical field [0001] The invention belongs to the installation field of transformers and related equipment, and in particular relates to a lifting method for transformers. Background technique [0002] With the development of the power industry, transformers have entered residential areas and commercial areas in large numbers. Being in a noisy environment for a long time will affect people's quality of life at least, and cause permanent damage to people's hearing at worst. Therefore, it is of great significance to take effective measures to reduce the noise caused by transformers. [0003] At present, there are several ways to reduce the noise of transformers: reducing magnetostriction; improving the stacking quality of silicon steel sheets; controlling the natural frequency of the iron core; controlling the noise of the cooling system; Soundproof walls, soundproof rooms, etc. The first four methods consider the vibration source and reduce noise by changing the character...
