ARRANGEMENT OF THE CDD(E) CELL OF THE 35 kV CIRCUIT BREAKER Russian patent published in 2023 - IPC H02B11/18 H02B11/02 H02B5/00 

FIELD: electrical engineering.

SUBSTANCE: arrangement of the CDD(E) cell of the 35 kV circuit breaker consists of a gas-insulated tank circuit breaker, busbars with support insulators, a spring drive, surge arresters, electrical circuit connectors, fences and a maintenance corridor. A support platform is additionally provided under the circuit breaker tank, to which the circuit breaker is fixed with the help of embedded outlets. Under the support platform there is a chassis-frame with rollers for rolling out the circuit breaker. A platform lifting mechanism is provided between the support platform with circuit breaker and the chassis-frame. The lifting mechanism of the platform is driven by an 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 hinge between the rods is fixed in a vertical plane. The height level of the platform lifting mechanism determines the disconnection or connection of parts of the circuit breakers.

EFFECT: creation of a compact design of a complete switchgear with a voltage of 35 kV.
