I-XJ3-D Protective Relay

Okujwayelekile

Ukuhluleka kwesigaba se-XJ3-D kanye nokudluliselwa kokuvikela kokulandelana kwesigaba kusetshenziselwa ukunikeza ukuvikelwa kokuvinjelwa kwe-overvoltage, undervoltage kanye nokwehluleka kwesigaba kumasekhethi e-AC ezigaba ezintathu nokuvikelwa kokulandelana kwesigaba kumadivayisi okudlulisela angenakuhlehliswa futhi nezici zokusebenza okuthembekile, ukusetshenziswa okubanzi nokusetshenziswa okulula.

Umvikeli uqala ukusebenza uma exhunywe kumjikelezo wokulawula amandla ngokuhambisana nomdwebo.Uma i-fuse yanoma yisiphi isigaba sesekhethi yezigaba ezintathu ivuliwe noma uma kukhona ukwehluleka kwesigaba kusekethe yokuphakelwa kukagesi, i-XJ3-D isebenza ngokushesha ukuze ilawule othintana naye ukuze inqamule ukunikezwa kwamandla kwekhoyili ye-AC contactor isifunda esikhulu ukuze othintana naye oyinhloko we-AC contactor asebenze ukuze anikeze umthwalo ngokuvikelwa kokwehluleka kwesigaba.

Lapho izigaba zesigaba sesithathu zedivayisi engabuyiseleki emuva enokulandelana kwesigaba esinqunywe kusengaphambili zixhunywe ngokungalungile ngenxa yokunakekelwa noma ukushintsha kwesekethe yokuphakela amandla, i-XJ3-D izohlonza ukulandelana kwesigaba, imise ukunikeza amandla kumjikelezo wokuphakelwa kwamandla futhi ifinyelele umgomo. yokuvikela idivayisi.
