O'rta chastotali payvand choklari orasidagi masofaga ta'sir qiluvchi omillar

O'rta chastotada nuqta choklari orasidagi masofanuqtali payvandlashoqilona ishlab chiqilgan bo'lishi kerak; aks holda, bu umumiy payvandlash effektiga ta'sir qiladi. Odatda, oraliq 30-40 millimetr atrofida. Spot choklari orasidagi o'ziga xos masofa ishlov beriladigan qismning texnik xususiyatlaridan kelib chiqqan holda aniqlanishi kerak. Haddan tashqari ko'p yoki juda ko'p bo'shliqlar ham mantiqsizdir.

Nuqtali payvandlash masofasiga ta'sir qiluvchi omillar quyidagilardir:

Payvandlash ketma-ketligi:

Payvandlangan nuqtalar har ikki tomonga taqsimlanganda, joriy taqsimlash nisbati bir tomondan boshqasiga qaraganda kattaroqdir.

Ish qismining sirt holati:

Yog 'ifloslanishi va oksidlanish qatlamlari kabi sirtni noto'g'ri ishlov berish, kontakt qarshiligini oshiradi, bu esa payvandlash sohasidagi umumiy qarshilikning kuchayishiga va filialning nisbatan qisqarishiga olib keladi, natijada oqim kuchayadi.

Elektrod va ishlov beriladigan qism o'rtasidagi payvandlanmagan joy aloqasi:

Elektrodlar va payvandlanmagan joylar orasidagi aloqa ba'zan oqimning sezilarli darajada o'zgarishiga olib kelishi mumkin va hatto ishlov beriladigan qismga zarar etkazishi mumkin.

Ish qismlarini yomon yig'ish yoki haddan tashqari qattiq yig'ish:

Payvandlanmagan joylar orasidagi haddan tashqari aloqa sezilarli oqimning burilishiga olib kelishi mumkin.

Bir tomonlama nuqtali payvandlash jarayonining xususiyatlari:

Ikkala payvandlangan qism bir xil qalinlikda bo'lsa, filial empedansi payvandlash empedansidan kichikroq bo'lsa, oqimning burilishi payvandlash joyidan o'tadigan oqimdan kattaroq bo'ladi.
