BLOCKING WITH GEOMETRIC CLOSURE FOR PREVENTION OF SWITCH CONNECTION Russian patent published in 2009 - IPC H01H9/26 

FIELD: electricity.

SUBSTANCE: invention is related to mechanism of blocking (1) for prevention of energy accumulator discharge in switch in area of electric distribution of energy with key switch (2), which in position of blocking mechanism (1) unblocking is connected by means of element of force transfer (4) via geometric closure to discharge triggering device (10) for discharge of energy accumulator, so that connecting motion acting at switch (2) is introduced through element of force transfer (4) into discharge triggering device (10). Element of force transfer (4) is connected to facilities for interruption of geometric closure (9, 17), arranged with the possibility of blocking mechanism changeover (1) into blocking position, in which geometric closure is eliminated. Key switch (2) and element of force transfer (4) in unblocking position are directed movably in common longitudinal direction, so that pushing motion of key switch (2) via longitudinal motion of force transfer element (4) is introduced into triggering device (10). Force transfer element (4) is installed as swinging so that in position of blocking direction of force transfer element (4) motion is oriented at the angle to pushing motion of key switch (2), besides facilities for interruption of geometric closure (9, 17) are connected to drive shaft (11) of switch and/or with auxiliary switch.

EFFECT: improved compactness and reliability of blocking mechanism operation.
