Zusammenfassung:	PURPOSE: A gas insulated switchgear with a dual gas injection nozzle is provided to supply an arc extinguishing and a cooling effect by spraying a gas to different directions in order to distinguish an arc which is generated in an opening operation. CONSTITUTION: A moving contact(10) is touched with or separated from a fixed contact point. A nozzle sprays a compressed gas to extinguish an arc which is generated in a breaking operation. The nozzle is composed of a fixed nozzle(80) and a moving nozzle(50). The fixed nozzle is formed in the fixed contact point. The moving nozzle is formed in the moving contact. A cylinder(30) stores a gas which is sprayed in the breaking operation. The moving nozzle is formed passing through the inside of the moving contact and sprays the gas in a cylinder to the arc in the breaking operation.
