At the place of its installation НКУ-РУСН is stationary and intended for indoor
operation, in the absence of vibrations or strokes. Environment should be
explosive-free, should contain no current-conducting dust, aggressive gases
and vapors in the concentrations reducing an insulation level within prohibitive
limits.
Design features
НКУ-РУСН is manufactured in the form of two-way servicing, arranged in one or
two rows, unite by a busbar bridge.
НКУ-РУСН is composed of the following cabinets: 0,4кВ input sections,
section breaker, distribution and general section units. A required number
of cabinets is determined by a diagram of primary connections, parameters
(dimensions) of automatic circuit breakers.
The cabinets of input, section breaker and distribution are completed with
automatic circuit breakers with a manual or motor drive of plug-in or pull-out
action. For mating НКУ-РУСН with a supply transformer piggyback cabinets are
manufactured.
