Definitions

  • the invention relates in particular to the field of circuit breakers or disconnectors for medium-voltage generators, placed in a protective sheath, and using cooling devices called “heat pipes” that operate with a phase-change heat-transfer fluid.
  • a heat pipe is presented in the form of a long hermetically-sealed enclosure containing a fluid with its gaseous phase and its liquid phase in equilibrium, in the absence of any other gas, ignoring traces.
  • Heat pipe Thermal apparatus in the form of a long hermetically-sealed enclosure containing a fluid with its gaseous phase and its liquid phase in equilibrium. Heat is transferred from the hot portion to the cold portion of the tube by vaporizing the liquid phase and condensing the vapor in the cold portion.
  • a method that is generally used consists in making more uniform the temperature of the air that is in contact with the various heating and heated parts of the circuit breaker concerned.
  • the cooling inside such a protective sheath may take place by natural or forced convection of the air enclosed therein and in which the circuit breaker is to be found, the prevailing temperature inside the protective sheath being considerably higher than the prevailing temperature outside, by 30° C. to at least 40° C.
  • Another solution consists in providing an increase in the current flow section in the various transmission elements, and thus increasing the size of circuit breaker parts.
  • FIG. 1 shows, in section, an embodiment described in that document.
  • FIG. 1 mainly shows a medium-voltage conductor 2 or the casing of a circuit breaker. It is surrounded by evaporators 3 forming part of a cooling assembly 1 therefor.
  • Such an assembly is accompanied by an insulating sleeve 7 surrounding a device operating with a phase-change heat-transfer fluid 5 in order to evacuate the heat collected by the evaporators 3 .
  • a flexible sleeve 9 completes the assembly.
  • the various parts are placed together inside a protective sheath 8 .
  • the cooling assembly opens out to the top of this protective sheath 8 leading to a condensation device 4 , e.g. with fins.
  • the object of the invention is to propose a different solution for this type of device.
  • the invention mainly provides a cooling device using phase-change heat-transfer fluids for medium-voltage apparatus and comprising at least one heat pipe.
  • the heat pipe(s) is/are placed in such a manner as to penetrate in part into the apparatus and is/are electrically insulated, in this embedded portion, by means of a sleeve that is both electrically insulating and a good conductor of heat.
  • the sleeve is made of sintered aluminium nitride.
  • the outside portion of the heat pipe(s) riot penetrating into the apparatus terminating at a condenser is provided with an electrically insulating sleeve.
  • Each heat pipe may possess an electrically insulating ring on an outside portion of the electrically insulating sleeve.
  • each heat pipe may possess an electrically insulating sleeve on its outside portion.
  • FIG. 1 shows a prior art cooling device
  • FIG. 2 partially in section, shows the technology used in the device of the invention
  • FIGS. 3A , 3 B and 3 C are cross-sections showing three embodiments of the invention.
  • FIG. 4 is a longitudinal section showing the device of the invention, in particular that shown in FIG. 3C .
  • FIG. 1 shows a portion of the casing 10 of a circuit breaker, the casing having a certain thickness in which the heat due to the flow of electricity at medium and high voltage and amperage accumulates.
  • FIG. 2 two heat pipes are shown penetrating in part into the casing 10 of the circuit breaker.
  • the portion 12 A of the heat pipe that is embedded in the casing 10 of the circuit breaker is therefore heated.
  • the fluid in the heat pipe 12 vaporizes when accumulating the energy.
  • the gas is thus diffused inside the heat pipe 12 until it reaches the non-embedded, opposite end 12 B, where it condenses.
  • the embedded end 12 A is surrounded by a sleeve that is both electrically insulating relative to the casing 10 of the circuit breaker and also a good conductor of heat.
  • the assembly may be completed by a ring made of electrically insulating material that surrounds the outside portion 14 A of the electrically insulating sleeve in order to increase the creepage distance.
  • the outside portion 12 B may also possess a second electrically insulating sleeve 18 in order to increase the creepage distance.
  • FIG. 3A a first embedment of such a principle in a circuit breaker 20 is shown.
  • two heat pipes 12 both have respective embedded portions 12 A that penetrate into the casing of the circuit breaker 20 .
  • the end of the outside portion 12 B of each of these heat pipes 12 is surrounded by a system of fins 26 in order to form a condenser 24 so as to enable the heat to dissipate outside the enclosure 22 in which the circuit breaker 20 is placed.
  • the liquid returns by gravity, thereby leading the condenser 24 to be placed high up. If the inside of the heat pipe 12 is provided with channels, liquid return is accelerated by capillary force, and this also enables the condenser 24 to be placed lower down, while accepting a loss of efficiency.
  • circuit breaker may be placed on an insulating support 28 .
  • condensers 24 are therefore placed on the roof of the enclosure 22 .
  • Both heat pipes 12 are implanted in the circuit breaker 20 , in a slightly offset manner, one on each side, so that their outside ends are further apart from each other. Thus, they may reach condensers 24 that are placed relatively far apart on the enclosure 22 .
  • FIG. 3B shows an embodiment with the same elements as the embodiment shown in FIG. 3A .
  • a fan device 30 is provided above the enclosure 22 in order to promote the flow of air through the condensers 24 , and more precisely to promote the flow of air between the fins 26 thereof.
  • FIG. 3C shows a third embodiment that makes use of a third heat pipe 42 A, placed between the two laterally offset heat pipes 42 B.
  • each heat pipe 42 A, 42 B terminates in at least one condenser 24 .
  • FIG. 4 is a longitudinal section showing the manner in which the heat pipes 42 A, 42 B may be implanted at various points along a circuit breaker 20 , or on other switchgear 50 associated with circuit breakers 20 that are always placed inside an enclosure 22 , such as busbar section isolators, for example.
  • Each heat pipe 42 A and 42 B is always connected to a condenser 24 that is placed on the roof of the enclosure 22 .
  • the main advantage of such a device is that it adapts to various heat pipe and cooling element technologies that have already been tested, without needing to develop insulation methods that need to contain the cooling liquid.
