4. Structure Introduction
FN16A-12 Series indoor AC high voltage vacuum load switch consists of a chassis vacuum interrupter, isolating switch, grounding
switch and actuator components. Through the upper and lower insulators
isolating switch fixed to the bottom frame. Vacuum interrupter chamber through
the insulator is fastened to the upper and lower frame, the upper and lower
brackets to support the installation of the insulators, increasing the product
overall structural stability. Grounding switch removable, mounted on the lower
end of the vacuum interrupter, operating mechanism mounted on the inside of the
base chassis, mechanical locking device left and right sides of the chassis.
FN16A-12RD/200-31.5 Type combination units within FN16A-12 in combination with
a high-voltage load switch current limiting fuse together the indoor high
voltage switchgear, the upper end of the fuse is fixed to the lower bracket of
the vacuum interrupter, the lower end is fixed to the seat by contacting the
insulator, lower bracket grounding switch and fuse together. Grounding switch
and disconnecting switch with mechanical interlock.
