Description

A combined distribution transformer bench and its use method

technical field

The invention relates to a distribution transformer stand and its use method, in particular to a combined distribution transformer stand and its use method.

Background technique

The distribution transformers are rotated regularly, and the main distribution transformer needs to be detached from the stand, and then the backup distribution transformer should be installed on the stand. Under normal circumstances, a crane is required for this rotation; when the boom of the crane is in operation, due to the operator's visual angle, the safe distance between the boom and the high-voltage down conductor may be insufficient, and then an electric shock accident may occur. The distribution transformer bench is composed of two channel steels, four support irons and four pad irons. Among them, the weight of a single channel steel is 100 kilograms, and it is time-consuming and labor-intensive to install. If the installation environment of the distribution transformer bench is not spacious enough, and the crane cannot drive in, it will be more difficult to disassemble and assemble the transformer, prolonging the working time and affecting the user's experience of using electricity.
