Passiv harmonik filtrlar THDi 5% O'zgaruvchan chastotali haydovchi tizimida keng qo'llaniladi
Zamonaviy elektr jihozlari kuchlanish barqarorligi va quvvat sifatiga qattiq talablar qo'yadi.Elektr tarmog'i harmonik va boshqa elektr buzilishlaridan xoli bo'lishi kerak.Shuning uchun Noker passiv garmonik filtri paydo bo'ldi.Noker harmonik filtrlari 6 impulsli quvvat konvertorlari tomonidan so'rilgan oqimdan harmonikani yo'q qilish uchun maxsus ishlab chiqilgan, masalan, motorlar, UPS va boshqalar uchun chastota inverteri.
Bular quvvat konvertorlarining kirishini filtrlash uchun moslashtirilgan induktiv va kondansatkichlarning ketma-ket parallel birikmasiga asoslangan mohiyatan passiv filtrlardir.
1. Joriy to'lqinning tarmoqqa va o'rnatishning qolgan qismiga nisbatan buzilishini qayta tiklash
2. IEC 61000-3-4, IEC 61000-3-12, IEC 61800-3 va IEEE-519 ga muvofiqligi
3. O'rtacha kvadrat tokning (RMS) kamayishi bilan energiyani tejash, shu bilan kV*A talabini kamaytirish
4. Uskunaning kamroq kuchlanishi va hosil bo'ladigan issiqlik yo'qotishlarining mos ravishda kamayishi bilan ushbu joydan yuqori bo'linmalarning ishlash muddatini oshirish.
5. Ishlab chiqarish jarayonlariga ta'sir qiluvchi konvertorga etkazilgan zararni va haddan tashqari kuchlanishning oldini olgan holda, joriy o'tish jarayonlarini cheklaydi.
6. Ta'mirlash xarajatlarini kamaytirish va eskirgan mashinalarni almashtirish uchun xarajatlarni tejash
