Osigurači za željeznice


Primjena:

  • za zaštitu željezničkih instalacija
  • za zaštitu visokonaponske sklopne tehnike


Prednosti

ETI-jevi osigurači za željeznice uspješno kombinuju dva, inače konfliktna, tehnička zahtjeva:

  • niski radni Džulov integral, neophodan kod zaštite poluprovodnika,

  • malu disipaciju snage, omogućavajući manje gubitke energije a time i manje troškove, prateći najnovije ekološke trendove.


Za postizanje jedinstvenih tehničkih karakteristika koristi se sasvim novi dizajn keramičkog tijela osigurača, posebna konstrukcija razvijena na osnovu dugogodišnjih stećenih znanja, koja omogućava znatno bolje hlađenje osigurača.

The operation of fuses is especially adapted for railway applications, as they have improved resistance to current cyclic loading, a phenomenon that causes unnecessary fuse operating in these applications. This way, ETI’s Railway Fuses help decrease downtime significantly, leading to further cost savings and improved efficiency.

The melting element inside Railway Fuses is made of silver, which makes them highly insensitive to ageing processes.

ETI Railway fuse-links ensure short circuit protection from minimum breaking capacity (5 x In) up to maximum breaking capacity 30kA d.c. at time constant 15ms.

Primjena
Protection of DC link and semiconductor devices (diode, tiristori, GTO) in railway inverters.

Standardi
ETI osigurači za željeznice su u skladu sa IEC 60269-4 i IEC 60077-5 standardima.
