Abstract (en)
[origin: WO2011051202A1] The method according to the invention serves to cool a high-current medium-voltage electrical apparatus such as a circuit breaker. It consists in inserting two heat pipes (11) in series inside the latter, placing a first end (HA) of a first heat pipe (11) in the hotter (11C) of the hot parts (10A, 10C) of the circuit breaker (10) and a second end (11B) of the first heat pipe (11) in the less hot (10A) of the hot parts (10A, 10C). The other heat pipe (11) is placed between the less hot (10A) of the hot parts and a less hot part (10B) of the circuit breaker. One particular application is for high-current medium-voltage circuit breakers.
