COMPLEX OF ADAPTATION EQUIPMENT KAD-0.4 Russian patent published in 2019 - IPC H02B11/00 H02B1/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used for operation in electric power plants of three-phase alternating current with frequency of 50(60) Hz and rated voltage of 0.4 kV. Technical result is achieved by the fact that complex of adaptation equipment KAD-0.4 for electrical cabinets of 0.4 kV comprises rigid frame in form of metal frame, set of flexible adapter bus adapters, power switch with withdrawable switching module, handle for rolling in and fixed mating part, voltage transformer, fasteners. Transformer and power circuit breaker are installed on metal frame, at that fixed mating part of power switch is rigidly attached to metal frame by means of frame fasteners. In upper part of power circuit breaker there is a set of adapter bus adapters, consisting of large, medium and small buses, made with possibility of movement between each other at connection with fasteners of set of flexible adapter bus adapters with matching of their connecting sizes with internal dimensions of electric cabinets 0.4 kV.

EFFECT: simplified assembly, adjustment and maintenance of elements of electrical cabinets during modernization and replacement of switching equipment, including old power circuit breaker.
