ELECTRIC DRIVE FOR SWITCHING DEVICES ARRANGED AS CAPABLE OF ELECTRIC ENERGY ACCUMULATION Russian patent published in 2012 - IPC H01H3/26 

FIELD: electricity.

SUBSTANCE: invention relates to a switching device for switches or disconnectors (S) of closed and modular type, arranged as capable of accumulating electric energy and comprising at least one low-capacity source (AL) of supply of small dimensions, which is used only to charge an accumulator capacitor (C), serving as an accumulator of electric energy. Accumulated electric energy is transmitted into a motor (M) in the form of direct current as switches or disconnectors (S) open, close and return into the initial position. A source of supply (AL) is connected with an electronic control circuit (CC), which receives an opening command (AP) at the inlet and a closing command (CH). The electronic control circuit (CC) is connected with an accumulating capacitance circuit (C) and a transistor bridge (PT), which, in its turn, sets a direction of rotation of the specified motor (M) with the help of direct current depending on the specified opening command (AP) and closing command (CH) and condition of closing, opening and splitting or return into initial position accordingly in switches or disconnectors (S).

EFFECT: possibility to quickly and efficiently and safely to execute operations of closing, opening and return into initial position of electric lines with the help of a switching device, having a very compact design.
