Design and construction
SIBA HV Fuse-links have parallel connected pure silver fuse-elements. The design and
method of production of the elements ensure narrow tolerances of time-curren 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 mechanically fixed to the porcelain tube and additionally sealed by a durable elastic sealing medium. This sealing method has been proven over many decades of positive field experience and ensures tightness against ingress of humidity.

Design
SIBA HV High Voltage Fuses 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 contactor.
It conforms to IEC282-1,GB15166.2 and DIN standard.
Striker pin
SIBA HV Fuse-links are available with striker pins of force:
• 80 N (Part No. 30 … 13 for basic-type) and
• 120 N (Part No. 30 … 14 for variant-type)
The characteristics of both striker pins correspond 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 indicates the operating status of the fuse and actuates a microswitch for remote indication, and/or triggers a load break switch or a circuit breaker to open.
The temperature limiting function of the fuse striker pin
SIBA 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 SIBA striker pin system therefore includes the following functions:
• thermal protection of adjacent equipment, especially SF6 insulated switchgear
• limitation of failure current at the overload region
Higher temperatures on plastic fuse enclosures in SF6 -insulated switchgear can be caused by:
• selection of a fuse rating too low for proper transformer protection
• fuses loaded with fault currents below the minimum breaking current
• deterioration of fuse links caused by transient fault currents (e.g. lightning strike)
• transformer fault currents (e.g. winding short-circuit)
• additional temperature rise because of poor clip fitting Fuse-links with an integrated temperature limiter are compatible with standard fuse links. All coordination schedules can be used.
