LOAD BREAK SWITCH AGGREGATE DRIVE Russian patent published in 2018 - IPC H01H33/00 

FIELD: hardware engineering.

SUBSTANCE: invention relates to a high-voltage apparatus. Aggregate drive contains a manual mechanism for controlling the grounding knives with a removable handle, a lever and a plunger, a spring mechanism, the cocking thereof is also carried out by a removable handle, to control the main knives, resting on the control lever with the pitch, rotating along the arc of a circle and being thrown to the position corresponding to the on and off states, the locking element is made in the form of a spring-loaded lever consisting of two plates on a common axis with the possibility of locking the control mechanism with grounding blades in the “off” position, with the main knives turned on, as well as with a spring cocked to turn it on or off, and performing the functions of unlocking the specified mechanism while the main knives are turned off by returning the locking plate of the mechanism to the initial position with a pin of the platoon lever at the end of the shutdown stroke. It is also possible to block the charging of the springs for switching on or off when the grounding knives are turned on and, as a result, the switched on condition of the main knives.

EFFECT: technical result is simplified and increased reliability of the drive.
