<p><P>PROBLEM TO BE SOLVED: To provide a compound type gas-insulated switchgear, in which the number of tanks is decreased, turning miniaturization and turning reduction in cost can be realized, additional new construction of an electric station and site installation workload in the extension work can be decreased, and an installation term can be shortened. <P>SOLUTION: The compound type gas-insulated switchgear has arranged two standard units TB2 with the setting length of the standard unit TB0 apart for conforming the shaft center of a tank 20 to be aligned substantially in a single row, with a bushing 24 of the standard unit TB2 mutually connected by an overhead electric line 31 so as to constitute the electric circuit of single-line diagram units. In the standard unit TB2 has arranged a breaker 21 and disconnecting switches 22, 23 in a substantially linear shape, stored in the tank 20 with the disconnecting switches 22, 23 positioned at both sides of the breaker 21, a grounding switch 25 is connected between the breaker 21 and the disconnecting switches 22, 23. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
