SWITCHING DEVICE WITH BREAKING AND/OR EARTHING FUNCTION Russian patent published in 2008 - IPC H01H31/02 

FIELD: electrical engineering.

SUBSTANCE: switching device contains encapsulating vessel (1) filled with insulating gas. Inside vessel (1) earthing contact (14) and breaking contact (15) are fixed. Further inside vessel movable contact element (9) is installed, which is displaced along axis (8) and is engaged or disengaged with at least one of both contacts (14, 15). Drive (13) that passes through the wall of vessel (1) and is loaded form outside with the force affects movable contact element (9). This drive (13) has holder (12) that is displaced along axis (8) and passes radially in conducting pipe (11). Movable contact element (9) contains at least one of two mostly contact tubes (9', 9") sectionally connected to holder. Tube (9') forms response contact of earth lead (E) that contains fixed earthing contact (14), and tube (9") - response contact of breaker (T) that contains breaking contact.

EFFECT: invention solves task of switching device creation, which may be easily re-equipped by addition or removal of contact tubes (9', 9") so that depending on the necessity both breaking and earthing functions may be performed, or breaking and earthing functions separately.
