Abstract

A system includes a portable transformer repair station that includes a portable building. The portable building includes a framework, a roof, and walls having a disassembled building configuration and an assembled building configuration. The portable building is configured to be transported in the disassembled building configuration. The portable building is configured to enclose a transformer repair space in the assembled building configuration. The portable transformer repair station also includes a portable floor having a disassembled floor configuration and an assembled floor configuration. The portable floor is configured to be transported in the disassembled floor configuration. The portable floor is configured to be disposed within the portable building in the assembled floor configuration. The portable transformer repair station also includes a portable oven configured to be disposed within the portable building. The portable oven is configured to remove moisture from a core and coils of a high voltage power transformer.

Description

BACKGROUND OF THE INVENTION[0001]The disclosed subject matter relates to large power distribution transformers, such as transformers disposed at a power plant that generates and distributes electricity to a power grid. More specifically, the disclosed subject matter relates to repair of these large power distribution transformers.[0002]Transformers are devices that transfer electrical energy from one circuit to another through inductively coupled conductors, namely coils of the transformer. Transformers may be used to step up, or increase, or step down, or decrease, the voltage of an alternating current. In certain transformers, the coil consists of windings of wire wound around a ferromagnetic core. During use, transformers may be subject to maintenance issues, such as coronas, electrical breakdowns, internal arcing, and so forth. Thus, transformers may undergo regular maintenance to help prevent such maintenance issues. For example, some transformers may be rewound on a regular ba...
