XRNT4-15.5, XRNT4-24, XRNT4-40.5 High voltage fuses for oil
immersed transformer backup protection
The series high voltage current limiting fuses of XRNT4-15.5,
XRNT4-24, XRNT4-40.5 for oil immersed transformer protection, they
are suitable for rated AC power of 50Hz, rated voltage of 15.5kV,
24kV, 40.5kV power system.
As a power transformer and other power equipment short circuit
fault protection element. The fuse is installed in the transformer
oil of the American transformer , which can be used in the same box
with load switch of transformer .
The high voltage current limiting fuse can be connected in series
with the high voltage transformer overload protection fuse to form
the high voltage current limiting fuse of full range protection.
The high voltage fuse will break the circuit , when the
overload current exceeds the specified value for a little
time. The high voltage backup fuse will break the short
circuit current , when the wrong current passes through the fuse
.The product can be widely used in equipment distribution
protection of wind power generation, solar power generation,
tidal power generation and so on .
This product has the characteristics of not causing any pollution
to transformer oil when breaking short circuit current, stable
time-current characteristic curve, significant current limiting
characteristics of backup fuse, strong breaking ability, the
maximum breaking current can reach 50kA.
