FIELD: electrical engineering. SUBSTANCE: proposed air-insulated switchgear that has one or more spatial zones for installing circuit-opening devices and/or cable entries, and/or collecting buses for power supply and distribution is made in the form of modular-structure cubicle divided by partitions into separate compartments accommodating pressure release devices, quantity of these compartments depending on type of switchgear. Compartments formed by partitions are intercommunicating through desired number of flow passages. EFFECT: minimized number of different modules and reduced design volume without reducing safety requirements. 5 cl, 3 dwg
