364 IN THE LINE OF POWER Fig.1 High Voltage Fuse-Links Technical data General information HV Fuse-Links have been used for reliable protection in mediumvoltage switchgear and controlgear and systems for decades. They protect apparatus and equipment against the thermal and dynamic effects of short-circuits. The outstanding features of EFEN HV Fuse-Links are: • High breaking capacity • High current limitation • Low switching voltage • Quick breaking • Non-ageing EFEN HV Fuse-Links conform to the following standards: • VDE 0670 T4/IEC 60 282-1: High-voltage fuses “current-limiting fuses” • VDE...

365 IN THE LINE OF POWER High Voltage Fuse-Links Technical data Rated voltage range It is important for HV Fuse-Links that they must be operated at the voltage for which it has been rated. Accordingly, the operating voltage corresponds to the maximum rated voltage of the Fuse- Link. Owing to the switching voltage occurring during arcing, the Fuse-Link cannot be used at lower voltages without limitation. A lower operating voltage at which the Fuse-Link can still be used without exceeding the system insulation level during extinction must therefore be taken into account. From these two values...

366 IN THE LINE OF POWER High Voltage Fuse-Links Technical data Description of further applications of EFEN HV Fuse-Links Protection of high-voltage motors With EFEN HV back-up Fuse-Links, high-voltage squirrel-cage motors can be protected against the consequences of high short-circuit currents. An overload must be disconnected by accompanying protective device. Protection of high-voltage capacitors It is possible to protect individual capacitors using EFEN HV back-up Fuse-Links in the event of a short-circuit. However, particular aspects must be taken into account with respect to the rated...

367 IN THE LINE OF POWER High Voltage Fuse-Links Technical data Protection of transformers The following should be observed for HV Fuse-Link selection: a) Transformer ratings – Service voltage (U) – Rated output (S) – Relative short-circuit voltage (uk %) – Inrush current (8...12 IN) b) Time-current characteristic of HV Fuse-Links c) Secondary devices/selectivity Procedure based on an example: A 630 kVA transformer has a transformer rated current of 18,2 A at a service voltage of 20 kV. The relative short-circuit voltage is 4 % and the inrush current is 12 x lN. The short-circuit current on...

In these substations HV fuses are enclosed in narrow fuse compart ments which on the one hand prevent efficient cooling of the fuses and on the other hand have a limited thermal power acceptance themselves (as a rule about...

369 IN THE LINE OF POWER High-voltage alternating current switch-fuse combinations acc. to VDE 0671 T105/IEC 62 271-105 In order to increase the utilization range of a switch, it is combined with current limiting HV Fuse-Links. This combination unit offers short-circuit protection in addition to load switching capacity. HV Fuse-Links provide short-circuit protection, while the switch interrupts the currents below the take-over current of the combination unit. In addition to the inrush current, short-circuit current on secondary terminal short-circuits and low voltage selectivity, the...
