DISTRIBUTION SUBSTATION OF MEDIUM VOLTAGE Russian patent published in 2017 - IPC H02B1/20 H02B13/00 

FIELD: electrical engineering.

SUBSTANCE: according to the invention, distribution substation (1) of medium voltage contains multiple functional units (4) located nearby in the first direction, wherein: at least one functional unit (10, 20, 30) of the distribution device has three cells (50) made able to interrupt current flowing through them. Each cell (50) has identical the first and the second connecting terminals (60) formed by insert (62) sealed in insulating support (64) and projecting from it through a connecting surface of insert (62) located in the center of the said support (64) disc. Discs of the first and the second terminals of each cell (50) are aligned in the second direction orthogonal to the first direction. Two functional units (4) contain three connecting tips (220), which form one end of connector (200) containing on its second end connecting device (202) for connection to terminals (60) of cell (50) of the distribution device. Functional units (4) are interconnected by buses (100) containing two connecting devices (102), which are similar and can be applied onto connecting devices (202) of connectors (200). Connecting devices (102, 202) contain metal connecting insert (110, 210) built in deformable insulating support (104, 204) and open out of it in the center of the two connecting surfaces, herewith the length of insert (110, 210) is less than the thickness of support (104, 204) at rest.

EFFECT: higher compactness and resistance to internal arcs.
