Abstract
 The mine dry-type transformer has the following advantages such as energy-saving low-noise and high reliability. The birth of underground flameproof dry-type transformer has solved the problem of underground power supply much better. So the research and design of the mining flameproof dry- type transformer has a very important value.
 This article firstly introduces the basic knowledge of the mining transformer and summarizes the technical specifications and structural characteristics of the mining flameproof dry-type transformer. And then on this basis the article briefly elaborates its design theory. And as an example of KBSG9-1250/10, this article systematically gives the design process of mine dry-type transformer. It emphasizes the electromagnetic computing, which includes calculation of transformer core, calculation of winding, insulation calculation, loss calculation and calculation of short circuit impedance. And at last parts of engineering graphics are drawn.
