HIGH-VOLTAGE SWITCHGEAR OF OPEN DESIGN Russian patent published in 2009 - IPC H02B5/06 

FIELD: electricity.

SUBSTANCE: high-voltage switchgear is provided with at least one assembled bus of open design (11, 12) and two switchgear cells or chambers capable of connecting to the assembled bus, and at least one sealed and gas-insulated module tripping circuit (30) being installed in one of the switchgear cells. The tripping circuit includes at least one break switch module (DS) and at least one power switch module (PS). In order to ensure transverse dismantling of at least one tripping modules (DS, PS) mounting module (MM) is placed between separating module and power switch module. The switchgear is ensured with high availability as each of the mostly loaded components in the tripping circuit, i.e. separator module and power switch module, may be removed from the switchgear by means of transverse dismantling without changing position of other components.

EFFECT: improved availability of device.
