To provide a cubicle-type gas insulated switchgear (C-GIS) having excellent insulation performance and this C-GIS can suppress electromagnetic force, which appears when applying current, to a minimum. The invented cubicle-type gas insulated switchgear has bus bar compartment 1 and VCB compartment 2 vertically joined each other, each of which is filled with insulating gas; vacuum valve 30 disposed vertically in VCB compartment 2; plate-shaped contacts 43a and 43b connected to upper shielding valve-terminal 31 and lower shielding valve-terminal 32 respectively; main circuit conductors 8 and 33 disposed in VCB compartment 2. And, ends of main circuit conductors 8 and 33 have finger contacts 44a and 43b respectively to joint correspondingly with plate-shaped contacts 43a and 43b; and disconnecting switches disposed in bus bar compartment 1 or VCB compartment 2 respectively. And, each of the disconnecting switches is connected to main circuit conductors 8 and 33 severally plate-shaped contacts 43a and 43b and finger contacts 44a and 44b are disposed on the line connecting between plate-shaped contacts 43a and 43b and plate-shaped contacts 43a and 43b and finger contacts 44a and 44b are connected and disconnected from the side of the VCB compartment 2; and each of the longitudinal axes lines of plate-shaped contacts 43a and 43b and of finger contacts 44a and 44b and of main circuit conductors 8 and 33 are located near the extension line of axes of moving lead 45 and fixed lead 46 oppositely arranged in vacuum valve 30. |
