ABB DSPAD/02/647 differensiële aflos in voorraad 100% eg met fabriek verseël

Produk Beskrywing

Die gestabiliseerde differensiaal-aflos SPAD 346 C is ontwerp vir die beskerming van twee-windende kragtransformators en kragopwekker-transformator. Die hoofkenmerke sluit in beskerming vir wikkelingkortsluitings, tussendraaifoute, aardfoute en kortsluitings, sowel as tussenwikkelingkortsluitings en poolkortsluitings. Boonop kan die aflos gebruik word vir die beskerming van drie-windende kragtransformators, mits 75% van die kortsluitingkrag na die kragtransformator uit dieselfde rigting verskaf word.

Die ABB DSPAD/02/647 differensiële aflos dien waarskynlik as 'n beskermende toestel binne 'n elektriese kragstelsel, wat toerusting beskerm teen potensiële skade wat veroorsaak word deur abnormale stroomtoestande. Hier is 'n uiteensetting gebaseer op sy naamkonvensie:

ABB DSPAD/02/647 differensiële aflos (moontlike funksie)

• Stroomdifferensiële beskerming: Monitor voortdurend strome wat 'n beskermde sone binnegaan en verlaat (bv. transformator, motor) om wanbalanse op te spoor. Beduidende verskille dui op 'n fout binne die sone, wat beskermende aksies veroorsaak.
  
• Vinnige foutopruiming: Skakel stroombrekers vinnig uit wanneer 'n stroomwanbalans opgespoor word, die foutiewe toerusting isoleer en skade aan omliggende komponente tot die minimum beperk.
  
• Hoë Akkuraatheid: Ontwerp om te onderskei tussen normale operasionele strome en foutstrome, wat die risiko van onnodige struikel verminder.
  
• Konfigureerbare instellings (moontlik): Kan verstelbare drempels bied vir huidige verskilbespeuring en tydvertragings vir ritaktivering om beskerming vir spesifieke toepassings te optimaliseer (kyk handleidings na).
  
• Kompakte ontwerp: Spaar ruimte binne elektriese panele vir doeltreffende stelselintegrasie.
