MEDIUM VOLTAGE CIRCUIT BREAKER IN SUBSEA ENVIRONMENT

The invention relates to a medium voltage circuit breaker in highpressure subsea environment, with a vacuum circuit breaker in a pressure tight housing, according to the preamble of claim 1. In orderto create a three phase switchgear for high environmental pressure, like in subsea, which is efficiently protected against this hight high environmental pressure, by fulfilling additionally high switching performance, the invention is, that for an electrical three-phase arrangement, one vacuum circuit breaker per phase is in arranged in a separate pole housing each, and the resulting three pole housings are mounted to a common base compartment, in which all the three drives for the three vacuum circuit breaker are arranged in. 本发明涉及根据权利要求1的前序所述的在高压海底环境中的中压断路器，其具有在耐压外壳中的真空断路器。为创建用于高环境压力(像在海底中)的三相开关设备，该三相开关设备通过满足附加的高开关性能从而有效地防止这种高环境压力，对于电气三相装置而言，本发明的每相的个真空断路器均被布置在单独的极外壳中，所形成的三个极外壳被安装到共同的底部隔间，该底部隔间中布置用于三个真空断路器的全部三个驱动器。
