| 摘要 | A vacuum switchgear system comprising a plurality of vacuum switchgears each comprising a vacuum container (24, 30, 40, 42) for accommodating the desired number of vacuum switches selected from a disconnecting switch or load break switch (44), an earth switch (46) and an vacuum circuit breaker (48). Each of the vacuum switches (44) has connecting terminals. The switchgears constitute different types of switchgears and are classified into power receiving side and power distribution side. Each switchgear is connected with an adjoining switchgear, an arrester (34) or a potential current transformer (10) by means of an insulated connecting conductor (32, 36, 38a-38i) having terminals around both ends, which are electrically connectable with and detachable from connecting terminals of the switchgears. | ||||||
