摘要： A non-liquid immersed transformer is provided. The transformer comprises a magnetic core and a coil winding forming a plurality of winding turns around the magnetic core and a cooling system. The cooling system comprises a heat exchanger, a main feeding pipe and a main return pipe, and a cooling pipe for the flow of a cooling fluid. The cooling pipe extends at least partly along the coil winding between a first point adjacent to an end of the coil winding, and a second point adjacent to the other end of the coil winding. The cooling pipe also comprises a plurality of convolutions to extend the path of the cooling fluid between one end of the winding and one of the main feeding pipe and the main return pipe

摘要： A non-liquid immersed transformer is provided. The transformer comprises a magnetic core and a coil winding forming a plurality of winding turns around the magnetic core; a cooling system and a first conductive connector. The cooling system comprises a cooling pipe for the flow of a cooling fluid, the cooling pipe extending along the coil winding and comprising a first point adjacent to a turn of the coil winding, and a second point adjacent to another turn of the coil winding. The conductive connector is arranged at one of the first and second points, to electrically connect an inner side of the cooling pipe with a turn of the coil winding.
