[0002] The flat-plate transformer is a specially designed form of power transformer. Its main feature is that it has a relatively flat shape, similar to a flat plate. This design makes the flat-plate transformer more suitable for some application scenarios with height restrictions or space constraints. Flat-plate transformers are usually used in indoor environments, such as buildings, factories or power distribution facilities. The flat-plate transformer is usually flat in shape, making it easier to embed it into spaces with height restrictions, such as the power distribution room inside some buildings. The protective structure can prevent external substances from entering the transformer, thereby preventing oil pollution, dust, moisture, etc. from affecting the transformer insulation and cooling system. Protecting the environment also means reducing the negative impact on the ecosystem around the transformer. The protective structure can prevent human damage and theft. For some vulnerable parts, the protective structure can provide additional protection and reduce the possibility of illegal entry into the transformer.
