Transformer Arc Extinguishing Current Limiting Fuse For Power Distribution PRW11-12/3-100 Type
PRW10-12F/100 on-load drop-out fuse (hereinafter referred to as
fuse) is suitable for power distribution line and power
distribution transformer of AC 50Hz, rated voltage 10kV. It is used
as overload and short circuit protection and opening and closing
load current.
Fuse is composed with underframe, arc suppression device and arc
extinguish device. When the fuse is in the closing position,
dynamic and static contact is compressed by a compressed spring, to
ensure that there is sufficient pressure between the contacts, on
the lower end of arc extinguishing pipe arranged the rotatable
torsion spring, after putting into the fuse elements, torsion
spring is tightening, the fuse in a state of tension, to ensure the
arc extinguishing pipe locking in the closing position. When the
line is overload or short circuit and fusing, fuse wire with
torsion spring, pulled out rapidly from the melting tube, and the
thermal energy of the arc produced large arc gas in the melting
tube, arc extinguish, to reduce the burning arc time and arc
material loss.
When the arc is extinguished, the fuse tube will automatically
dropped under the action of self weight and bridge type contact
spring, making a fracture. The arc extinguishing pipe is designed
into a step by step exhaust type. When breaking small current, gas
is discharged from the lower end of the exhaust port. When breaking
large current, gas rushed to open the upper cap, gas extinguished
by upper and the lower ends of the exhaust port to meet the
requirements of breaking different current on the same fuse.
