Definitions

  • the present invention relates to a transformer particularly for mobile and relocatable substations for the transmission and distribution of electric power at high, medium and low voltage.
  • Transformers for mobile and relocatable substations are currently machines which are produced in a substantially conventional manner, i.e., according to the typical standards of a static transformer, and are placed on a trailer or on a flatbed truck to be carried to the site where they are to be used.
  • transformers are performed ad hoc in each instance, so as to be able to fulfill to the needs of the various users, who generally have different requirements as regards electric specifications according to the country and/or power net in which the machine is to be installed.
  • the aim of the present invention is to solve the above problem, by providing a transformer particularly for mobile and relocatable stations for the transmission and distribution of electric power at high, medium and low voltage in which it is possible to provide a specifically designed structure for the mobile transformer, without merely adapting the arrangement of the accessories with respect to the conventional transformers.
  • a particular object of the present invention is to provide a transformer in which the tank can be kept the same and it is sufficient to produce only the active part of the transformer according to specific requirements.
  • Another object of the present invention is to provide a mobile transformer which is already in the operating configuration and can be easily and quickly installed at various sites and in different substations so as to be immediately ready for use.
  • Another object of the present invention is to provide a transformer which is always within road clearance profile limits, consequently avoiding the need to apply for special transport permits and allowing the user to move the machine at any time without any problem.
  • a transformer particularly for mobile and relocatable substations for the transmission and distribution of electric power at high, medium and low voltage characterized in that it comprises a self-supporting tank for containing the active part of the transformer, the bottom of said tank constituting a chassis which can be associated with wheels in order to form a transport truck which is integrated with said tank.
  • the transformer particularly for mobile and relocatable substations for the transmission and distribution of electric power at high, medium and low voltage comprises a self-supporting tank 2 which internally contains the active part of the transformer 3, which is typically constituted by a lamination core 4 and by corresponding windings 5.
  • the relevant characteristic of the invention is constituted by the fact that the bottom 10 of the tank constitutes a chassis which directly forms axles for the wheels 11, thus constituting a transport truck which is integrated directly with the tank.
  • the tank 2 is not merely the element for containing the active part of the transformer but it is an integrated element which directly provides the means for transporting and thus allows to have the transformer always ready for transfer to the location where it is to be used.
  • a bell-shaped element 20 is superimposed on the bottom 10 through the interposition of a suitable sealing element and forms the container of the active part of the transformer which, as is typical, is fully immersed in oil.
  • the bell-shaped element 20 is provided, in an upward region, with an oil expansion reservoir 21, thus obtaining a perfectly integrated system.
  • the high-voltage output insulators designated by the reference numeral 30, are arranged directly at the front wall of the bell-shaped element 20, while the low-voltage output insulators, designated by the reference numeral 31, are provided in the rear part, i.e., on the opposite wall.
  • a modular structure which is constituted by the bottom and the bell-shaped elements and in which the active part of the transformer is inserted.
  • the active part is the only one that needs to be redesigned according to the electrical characteristics required by the various users, while all the outer parts, in addition to the tank, remain unchanged.
  • a transformer is provided in which the outer casing that forms the tank of the transformer has a part, specifically the bottom, which also acts as a self-supporting chassis, which can be associated with wheels so that it directly forms the vehicle for transporting the transformer.
  • the materials employed, as well as the contingent shapes and dimensions may be any according to requirements.
