Title: A HIGH CURRENT VACUUM INTERRUPTER WITH SECTIONAL ELECTRODE AND MULTI HEAT PIPES
Abstract:
An electrode assembly (70) for a circuit breaker (10) is provided. The electrode assembly (70) includes a conductive assembly (90) and a heat transfer assembly (200). The conductive assembly (90) includes a stem portion (92) and a contact portion (94). The heat transfer assembly (200) includes a number of elongated bodies (202), a first heat transfer surface (204), and a second heat transfer surface (206). The first heat transfer surface (204) is disposed on the conductive assembly (90). Each heat transfer assembly body (202) includes a second heat transfer surface (206). Each heat transfer assembly body (202) is coupled to the conductive assembly (90) with the first heat transfer surface (204) coupled to a number of second heat transfer surfaces (206).
