System and method for realizing kerosene vapor-phase drying to on-site assembly transformer

Abstract

The invention relates to a system and a method for realizing kerosene vapor-phase drying to an on-site assembly transformer, in particular to a system and a method adopted for vapor-phase drying treatment in assembling and overhauling a transformer on site. The system uses a transformer oil tank for containing the transformer as a working capacity for the vapor-phase drying treatment, and the transformer oil tank is connected with vapor-phase drying equipment arranged outside the transformer oil tank by utilizing a connecting pipeline. For facilitating transportation and suiting the limitation and variance of the transformer mounting site, the invention assembles the vapor-phase drying equipment into a modulated mode. Accordingly, the system and the method of the invention can be adopted to achieve the aims of carrying out the vapor-phase drying treatment to the transformer on the transformer mounting site. Meanwhile, compared with a solid kerosene vapor-phase drying system, the invention has simpler system construction and decreases the manufacture and mounting costs of the vapor-phase drying treatment system of the transformer while thoroughly drying the transformer.

Description

technical field [0001] The invention relates to the field of transformer production and manufacturing, and more specifically, the invention relates to a system and method for performing gas-phase drying treatment on a transformer body by using a kerosene gas-phase drying treatment method at a transformer installation site. Background technique [0002] In recent years, with the rapid development of my country's electric power industry, especially the vigorous development of hydropower (clean energy), most of the industries that need electric power development in my country are distributed in the southwest and northwest remote areas (accounting for more than 80%), which is extremely inconvenient for the transportation of large workpieces . In this way, due to the limitation of transportation height, bridge load-bearing and other factors, it is impossible to transport a large transformer weighing hundreds of tons to the installation site as a whole, so the transformer is transp...
