- In detail
Low-voltage complete devices of the RUSN-0,4 series are manufactured in the form of boards of cell-like type with sliding automatic switches and relay blocks.
NKU of the RUSN-0,4 series is constructive represent a board which gathers from separate standard cases:
input cases (tire input, cable input) ShEVM8146... ShEVM8161;
cases of sectioning of ShEVM8171... ShEVM8173;
cases of all-section ShEVM8180 devices... ShEVM8188;
cases of control of ShEVM8190 transformers... ShEVM8199;
cases of the departing lines.
Cases of own needs of ShEV, ShEVM and ShEVI are completed with BEV, BEVM and BEVI blocks.
Dimensions (height x width x depth) of cases of input, mm: 2200x800x1000 or 2200x1200x1000, other cases 2200х800х1000.
The mass of one case, kg - 300... 400.
NKU of the RUSN-0,4 series can be placed in one or in two ranks. In the latter case boards RUSN-0,4 include the tire bridge.
The design of cases of RUSN provides:
bilateral service of cases;
installation of combined tires horizontally in the top part of a case in a separate compartment;
accession of auxiliary chains to relay blocks via sockets;
installation of power switches, standard relay and power blocks by request;
interchangeability of the same blocks.
From the forward party of cases (from a facade) expeditious service of sliding automatic switches and relay blocks is made. From the back party of a case in the corresponding compartments cable assemblies of the departing lines and current transformers are placed.
