Definitions

  • the present invention relates to a gas-insulated electric switchboard. Discussion of Background
  • Gas-insulated electric switchboards are used in the field of medium voltages and, because of the high dielectric strength of the gas SF 6 , enable parts under voltage in the electrical apparatus installed to be disposed close to one another. It would be possible to reduce more substantially the dimensions of gas-insulated switchboards by disposing electrical equipments still more compactly. However, such equipments generate heat, which has to be dissipated.
  • one object of this invention is to provide a novel gas-insulated coolable electric switch ⁇ board which has effective cooling means, is of simple, inexpensive construction and takes up a limited space.
  • the heat exchanger is made in one single piece.
  • Another constructional facilitation is possible because the heat exchanger is composed of an inside part and an outside part, said parts being back to back fixed and with metallic continuity on the wall of the electric switchboard. It is advantageously possible to create automatic gas circultion inside the cubicle and to improve the cooling efficiency because of the fact that the inside part of the heat exchanger has a finned conformation with parallel fins definining vertically extending channels. A similar conformation is advantageously provided in the outside part of the heat exchanger.
  • More intensive cooling of the gas inside the switchboard can be obtained by the provision in the inside and outside parts of the heat exchanger of a circuit containing a refrigerant fluid, for carrying heat from inside to outside, freon gas or the like.
  • More intensive cooling can likewise be achieved by associating a forced circulation pump with the circuit containing the heat transport fluid, the refrigerant fluid, the freon gas or the like.
  • Faster cooling can also be obtained by associat ⁇ ing an external refrigerating compressor with the heat exchanger.
  • more intensive cooling is obtained by associating a fan with the outside part of the heat exchanger.
  • the heat exchange takes place reliably by means of direct metallic conduction between a large surface inside the switchboard and a large outside surface.
  • Figure 1 shows in perspective the housing of a gas-insulated electric switchboard provided with a heat exchanger according to the invention
  • Figure 2 shows in perspective a first construc- tional variant of an electric switchboard according to the invention
  • Figures 3 and 4 each show in section another constructional variant of an electric switchboard accord ⁇ ing to the invention. DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • the reference numeral 1 designates the housing of a gas- insulated electric switchboard of any desired construc ⁇ tion, in the rear wall 2 of which is formed a heat exchanger given the general reference 3.
  • the heat exchanger 3 comprises an inside part 4 and an outside part 5, these parts having a plurality of parallel ribs 6 defining between them vertically extending channels 7.
  • the two parts 4 and 5 of the heat exchanger may consist of a single piece inserted into the wall 2 and fixed to the latter in such a manner as to form an integral part thereof, for example by means of brackets, perimetric frames or the like, in a manner not further illustrated.
  • the two parts 4 and 5 of the heat exchanger may also consist of independent bodies fastened together or fastened back to back with metallic continuity on the wall 2.
  • the conformation comprising fins 6 and channels 7 brings about the formation of automatic circulation of the gas inside the switchboard, as indicated by arrows in Figure 1.
  • a circuit or piping system 8 for the circulation in the heat exchanger of a fluid serving as a vehicle transporting heat from the inside to the outside.
  • a fluid of this kind may for example consist of water.
  • the piping system 8 may also carry a cooling fluid, for example freon gas, which extracts heat as the result of its change of state from liquid to gas and vice versa, as is known in refrigeration technique.
  • the fluids conducted through the piping system 8 may be subjected to forced circulation by means of a pump 9.
  • cooling of the outside part 5 of the heat exchanger 3 is effected by means of an external fan 10.
  • a com- pressor 11 is inserted into the piping system 8 provided in the heat exchanger parts 4 and 5, for the purpose of bringing about a refrigeration cycle.
  • the heat exchanger 3 is composed of an inside portion 4 and an outside portion 5, which portions are connected together metallically to form a single body.
  • the heat that is to be dissipated that is to say the temperature inside the cubicle
  • the outside part 5 and, through metallic conduction, the inside part 4 are thus cooled, with a consequent lowering of the temperature inside the switchboard.
  • An extension of the body of the heat exchanger 3 over a substantial part of the length of the cubicle produces a substantially uniform circulation of gas over the entire length of the cubicle. This permits effective and reliable removal of heat from all the electrical equipment housed in the cubicle.
