DEVICE FOR COOLING A MEDIUM-VOLTAGE APPARATUS USING INSULATED HEAT PIPES

摘要

The cooling device is suitable for fitting to existing installations, without redesigning them. It consists in using heat pipes (12) that are partly embedded in the casing (10) of the apparatus. This embedded portion (12A) of the heat pipe (12) penetrating into the casing (10) has a sleeve (14) that is both electrically insulating and a good conductor of heat. The device is for application to circuit breakers in a medium-voltage, high-amperage electrical installation.
