H.V. current -limiting fuses type S is mainly used in AC50Hz,rated voltage 3.6-40.5kV,rated
current up to 200A circuit for protection transformers and power equipments
from overload and short-circuit.It can also be used with load switch,vacuum
contact,etc.It conforms to IEC282-1,GB15166.2 and DIN standard.
S type H.V. HRC current-limiting fuses is insert installation.The striker parallels
to the fuse element made from pure silver.They are sealed in the fuse tube filled
with chemically treated high-purity quartz sand.The fuse tube is made from
heat resistance,high duty ceramic or expoxy glass.When fault circuit happes,the
fuse link melts,the high-resistant metal wire paralleling to fuse links melts immediately
at the appearance of the arc,and the striker jumps out to push the chained
equipment contact,signaling the melting automatically cutting the circuit.The
striker has spring type and powder type.Spring type striker use energy released
by spring to push the strker;Powder type striker use high pressure caused by
the lighting powder to push the striker.S type H.V.HRC current-limiting fuses has
many merits as high current-limiting ablilty,high breaking capacity,quick and
punctual in action,reliable in performance.
