Himoya tizimining yordamchi quvvat taqsimoti
Relion seriyali himoya relelari stansiyadagi kuchlanish pasayishi yoki doimiy tok batareya tizimidagi kuchlanish sakrashi sharoitida nosozlikni deterministik tarzda o‘chirish va SCADA telemetriyasini ta’minlash uchun past shovqinli doimiy tok quvvatini o‘zgartirishga tayanadi. 1MRK002239-BB yuqori kuchlanishli stansiya batareya ta’minotini (90–250 VDC) >90% o‘zgartirish samaradorligi bilan izolyatsiyalangan 24 VDC quvvat shinasiga aylantiradi. Integratsiyalangan o‘z-o‘zini nazorat qilish sxemalari ichki shina kuchlanishlarini uzluksiz kuzatib boradi va quvvat manbai yomonlashuvi yoki liniyada nosozlik yuz berganda Ichki zaxira nosozlik (IRF) signal kontaktini ishga tushiradi.
Tez-tez so‘raladigan savollar
S: 1MRK002239-BB moduli Relion himoya relesining qaysi slot joylashuvini egallaydi?
J: Modul orqa tomondagi P40 sloti uchun mo‘ljallangan bo‘lib, tashqi ulanishi X401 terminal blok ulagichi orqali amalga oshiriladi.
S: Quvvat manbai nosozligi vaqtida IRF o‘z-o‘zini nazorat qilish kontakti qanday ishlaydi?
J: Ichki nosozlik kontakti normal ishlash vaqtida quvvatlangan holda bo‘ladi; kirish quvvati yo‘qolganda, ichki ortiqcha kuchlanish yuz berganda yoki modul apparat nosozligida kontakt ochilib, stansiya signalizatsiyasini ishga tushiradi.
Joyida o‘rnatish bo‘yicha ko‘rsatmalar
- Relion korpusidan quvvat manbai modulini o‘rnatish yoki chiqarishdan oldin stansiyaning yordamchi DC ta’minotini uzing.
- Karta majmuasiga tegishdan oldin panel yeriga ulangan ESD bilak tasmasi yordamida o‘zingizni yerga ulang.
- Modulni shassi yo‘naltiruvchi relslari bo‘ylab P40 slotiga bir tekis suring va orqa panel ulagichlari to‘liq birikguncha davom eting.
- Vibratsiya sharoitida korpusning yerga ulanish uzluksizligi va mexanik mahkamlanishini ta’minlash uchun modulni ushlab turuvchi vintlarni orqa panelda mahkamlang.
- Stansiyaning 90–250 VDC yordamchi quvvat simlarini X401 terminal ulagichiga ulang va quvvatni yoqishdan oldin kuchlanish qutblari to‘g‘riligini tekshiring.
