Definitions

  • the invention particularly relates to the field of circuit breakers or disconnectors generators operating at medium voltage, placed in a protective sheath and using cooling devices operating with a heat transfer fluid phase change, called "heat pipes”.
  • a heat pipe is in the form of an elongated hermetic enclosure containing a fluid in equilibrium with its gaseous phase and its liquid phase, in the absence of any other gas.
  • One method, generally used, is to homogenize the air temperature by contact with the various heated and heated parts of the circuit breaker concerned.
  • the cooling inside such a protective sheath can be done by natural or forced convection of the air enclosed in it and in which the circuit breaker is located, the temperature prevailing inside thereof being significantly higher than the temperature outside, that is, from 30 ° C to at least 40 ° C.
  • Another solution is to provide an increase in the current flow section in the various transmission elements, so to go through an increase in the size of the parts of the circuit breakers.
  • the object of the invention is to propose a different solution for cooling the apparatus.
  • a first main object of the invention is a method of cooling a medium voltage electrical appliance with high amperage, having hot parts of which one hot part more each than the other hot part and parts less hot than the hot parts.
  • this method consists in inserting two heat pipes in series inside the apparatus by putting a heat pipe between the hot parts to evacuate the heat from the hottest part to the less hot part of the two hot parts and putting a first end of another heat pipe in the warmest of the hot parts and a second end of this other heat pipe in a less hot part than said hot parts. It is thus possible to extract the heat prevailing in the particularly hot parts and thus to homogenize the temperature in the apparatus.
  • Another main object of the invention is a cooling system of an electrical apparatus of the type circuit breaker or disconnector medium voltage and high amperage, having hot parts of which a hot part which is hotter than the other hot part and parts less hot than hot parts.
  • the system has a first heat pipe between the hot parts and another heat pipe whose first end is placed in the warmest of the hot parts and a second end is placed in a less hot part, the two heat pipes being in series.
  • FIG. 2 there is a high voltage electrical apparatus operating at high amperage, such as a circuit breaker 10. This is placed in a sheath 15, on insulating supports 18. Maneuvering elements 17 have been shown, in particular to the outside of the sheath 15. This is then placed itself on supports 19.
  • the circuit breaker 10 has fixed parts and moving parts. In all of these parts, there are parts or parts of a significant thickness.
  • hot parts 10C and 10A including the center of the circuit breaker 10
  • the hot parts 10C are hotter than the hot parts 10A which are in the region of the contacts of the circuit breaker 10.
  • the latter also has less hot parts 10B, which are therefore warmer than the hot parts 10A and 10C, placed eccentrically with respect to the center of the circuit breaker which is materialized by an axis A.
  • other less hot parts may be located towards the center of the circuit-breaker 10, provided that they are remote from the contacts of passage of the rated current
  • the method and apparatus of the invention utilize proven heat pipe technologies.
  • the heat is drawn directly to its source and routed to the outside of the device.
