Abstract
The method of the invention makes it possible to cool electrical switchgear operating at medium voltage and high current, such as a circuit breaker. The method consists in inserting serially two heat pipes () inside said switchgear, putting a first end (A) of the first heat pipe () in the hot portion of the hot portions (A,C) of the circuit breaker () and a second end (B) of the first heat pipe () in a portion that is cooler (A) of the hot portions (A,C). The other heat pipe () is put between the cooler of the hot portions (A) and a cooler part of the circuit breaker (). A particular application is provided for medium-voltage, high-current circuit breakers.
