COMPLETE DISTRIBUTION DEVICE OF EXTERNAL INSTALLATION WITH A VOLTAGE OF 35 kV (CDDE) Russian patent published in 2023 - IPC H02B11/18 H02B11/02 H02B13/00 H02B5/00 

FIELD: electrical engineering.

SUBSTANCE: complete distribution device of external installation with a voltage of 35 kV (CDDE). The device of the transformer cell CDD (E) with a voltage of 35 kV consists of a transformer tank with low-voltage and high-voltage terminals, busbars with support insulators, a terminal cabinet, surge arresters, electrical circuit connectors, high-voltage fuses, fences and a service corridor. At the end of the high-voltage outlet, the first part of the connector is additionally provided and fixed, the second part of the connector is fixed with the lower clamp of the fuse on the bolted flange of the surge arrester outlet. The upper fuse clamp is fixed with the tip of the bolt clamp of the busbar loop on the support insulator. The transformer tank is fixed with the help of embedded releases on an additionally provided support platform. Under the platform, a chassis-frame with rollers for rolling out the transformer tank is additionally provided. A platform lifting mechanism is provided between the platform and the chassis-frame. In turn, the lifting mechanism is driven by a high-speed electric motor with a gearbox and a horizontal threaded shaft along the entire length, as well as two rods pivotally fixed both to each other and to the threaded shaft. The platform lift level determines whether the connector parts are turned off or on.

EFFECT: compact design of the voltage transformer cell for a complete distribution device of external installation with a voltage of 35 kV.
