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 meaning :Fuse model
