Definitions

  • the invention relates to electrical engineering, in particular, to the systems of liquid evaporative cooling of the current-conducting parts of the power-engineering and technological equipment.
  • the inductance coils can be used in the power transformers, electrical machines and inductive heating equipment.
  • the inductance coils for generating the magnetic flux in the electrical devices and machines can be cooled by environment air or forcedly, due to circulation of cooling medium around the winding wire or in the channels and passages in the winding wires as well as due to evaporation of liquid cooling medium, i.e. by use of the evaporating-condensing cooling system.
  • a transformer is known that uses the system of the winding cooling intensification by way of heat pipe (See [1] SU N° 1096706, published on 07.06.1984).
  • a magnetic core with windings at its ends made of hollow rectangular or round winding wire is located.
  • the upper and lower fittings made of electrically insulating material, for example, ftoroplast are mounted. The fittings connect a space in the copper tube with upper (steam) and lower (condensate) headers.
  • a steam formation occurs inside of conductors, then a steam is fed to the steam header and enters the cooling element out of tank where it condenses in the form of liquid that flows under the action of gravity forces to the condensate header and passes to the winding wire channels.
  • the cooling agent inside of the sealed evaporating-condensing system reon is suggested.
  • the offered device for the transformer windings cooling has a number of drawbacks. Among them is a use of the hollow rectangular or round winding wire for winding making which decreases a copper space factor and deteriorates the energetic performance of a device.
  • a reliability of the cooling system declines essentially in view of hydraulic lock appearance when the channels are filled with condensate and steam if there are several turns of winding between the upper (steam) and lower (condensate) headers.
  • the system reliability can be essentially enhanced by using the upper (steam) and lower (condensate) headers on each turn of winding but it, in turn, raises essentially the structural complexity and reduces its fabricability.
  • a direct contact between the cooled tube and cooling liquid can be considered which has a high positive effect on an increase in thermal effectiveness of the evaporating-condensing cooling system.
  • a transformer is also known (See [2] SU JYS 10721 18, published on 07.02.1984) in which, the disc windings alternate on the core limb with flat heat tubes which heat-receiving part is placed between the coils while the heat-transfer one within the casing folds.
  • an efficiency of heat pickup from disc coils increases due to appliance of heat tubes but a placement of heat-release part in the form of flat cell in the casing folds rather than beyond its limits as was done in [1] reduces considerably the efficiency of heat power release to the surrounding environment.
  • the shortcomings of the prior arrangement include a limitedness of combinations of heat-carrier-body materials due to penetration of noncondensable gases when refueling and their release in the course of operation of heat tubes and as a result of leakages through microcracks, micropores and welding defects.
  • the most similar in the technical essence arrangement among existing ones is a unit for cooling of electrical coils (See [3] SU JSTs 851793, published on 03.07.1981) designed in the form of the cooled body with sealed vacuumized annular cavity for placement of the winding with cooling elements made of nonconductive capillary-porous material over the whole surface of winding and cooling fluid filling pores of capillary-porous material and 1-5% of annular cavity.
  • the cooling fluid rises contrary to gravity forces through the winding wire and cools the winding by evaporation.
  • the steam condenses as a result of using the secondary water loop.
  • a presence of nonconductive capillary-porous material over the whole surface of winding lowers appreciably the efficiency of heat-transfer from the winding to cooling fluid.
  • the use of the effect of the cooling fluid rise through the capillary-porous material is not entirely reasonable in this case and fluid could in full cover the electric winding.
  • a presence of the secondary water loop complicates essentially the unit as a whole.
  • the present invention provides an improvement of energy indicators of applying the inductance coils with simultaneous reduction in consumption of active electrotechnical materials and mass -dimensional characteristics of the electric device as a whole.
