<p>PURPOSE: To make the assembly work of a gas insulation switchgear easy and reduce the size of the switchgear by storing a breaker and a cable-side disconnector in a second insulating gas container which is separated from a first container wherein a bus-side disconnector is stored in insulating gas and partitioning the second container into a first unit for storing the breaker and a second unit for storing the cable-side disconnector. CONSTITUTION: In a first container 11 which is filled with insulating gas, a bus-side disconnector 2 and a bus 3 are installed. A second container 12 which is separated from the first container 11 and which is filled with insulating gas is constituted of a first unit 12a wherein a breaker 5 is assembled and which is connected with the first container 11 and a second unit 12b wherein a cable- side disconnector 6, etc., are assembled. The two units 12a, 12b are separable and they are connected into one body at a place denoted by symbol A. Due to this structure, a gas insulation switchgear can be assembled efficiently and its size can be reduced.</p> |
