Description XRNT4-15.5, XRNT4-24, XRNT4-40.5 High voltage
fuses for oil immersed transformer backup protectionThe 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. 1. Model and
