These fuses can be used in indoor system of 50Hz and 3.6kV, 7.2kV,
12kV, 24kV, 35kV and 40.5kV. It used together with other switch
equipments such as air load break switch, SF6 gas load break
switch, vacuum contactors. It can protects electric transformers
and other electric equipments against over load current or circuit
break current. It is also a neccessary accessoriy for high-voltage
switchgear, Ring Main Units, transformer substation.
Design and construction
Wuhuan HV Fuse-links have parallel connected pure silver
fuse-elements. The design and method of production of the elements
ensures narrow tolerances of time-current characteristics.
The fuse elements are wound on a ceramic support and are attached
to the silver plated connection caps by means of spot-welding. The
connection caps are fitted inside the silver plated copper end caps
by spot welding.
The copper end caps themselves are press-fitted onto the porcelain
tube which is glazed inside and outside.
The end caps are furthermore mechanically fixed to the porcelain
tube and additionally sealed by a durable elasticsealing medium.
This sealing method has been proven over many decades of positive
field experience and ensures tightness against ingress of humidity.
Wuhuan HV Fuse-links are available with striker pins of the force 80N and 120N.
The characteristics of both striker pins corresponds to IEC 60282-1, VDE 0670 Part 4 and are of the energy category "medium".
The striker pin system is connected by means of a high resistance parallel conductor. After melting the main fuse elements the striker pin will indicate the operation status of the fuse and open a load break switch or actuate a micro-switch for remote indication.
Wuhuan HV Fuse-links up to and including 160 A with a striker pin of 80 N are equipped with an integrated temperature limiter as standard. The temperature limiter is fitted inside the striker pin system. The XIKAI striker pin system therefore has the following functions:
thermal protection of adjacent equipment, especially SF6 Insulated switchgear
limitation of failure current at the overload region
improved properties for the switch-fuse combinations according IEC 60420
The integrated temperature limiter avoids inadmissible high temperatures - no matter for whatever reason they are
generated - in gas-insulated switchgear or narrow switchgear enclosures. By means of a melting activator
temperatures inside the fuse link enclosure are limited to below approx. 100°C. This design especially considers
continuity of current supply for the end user for as long as possible. The system reacts in such a way that short time
overloads do not cause the fuse to interrupt the circuit unnecessarily. Only when inadmissible values are exceedes the
fuse will open the switch via the striker pin.
Higher temperatures on plastic fuse enclosures in SF6-insulated switchgear can be caused by:
selection of a fuse rating too low for transformer protection
fuses are loaded with fault currents below the minimum operating current
deterioration of fuse links caused by transient fault currents (e.g. lightning strike)
transformer faults currents (e.g. winding short-current)
overloading of the fuse when loaded with currents as described in IEC 420 Test Duty 3
additional temperatures rise because of poor clip fitting
Fuse-links with integrated temperature limiter are compatible with standard Fuse links. All coordination schedules can be used.
