Yuqori kuchlanishli sim simlari, yuqori voltli yonish simlarini qanday tekshirish kerak

Avtomobilning yuqori kuchlanishli simlari elektr stantsiyasi uchun juda muhim rol o'ynaydi, chunki ular elektr pulsidan elektr plitasida elektr pulslarini uzatadi. Ta'kidlash joizki, havo yoqilg'i aralashmasi yallig'lanishining intensivligi va tartiblili simlarning samaradorligi va vazifasi, shuning uchun motorning uzluksiz va to'g'ri ishlashiga bog'liq. Uning soddaligiga zid, simlar turli xil "yaralar" ga ega va ularning egasi cho'ntagida yoki asabida boshqacha muammolarni keltirib chiqaradi. Bu haqda maqolada.

Yuqori voltli lashish simlari, yuqori voltli simlarga qanday vazifalar va talablarga beriladi

Birinchidan, yuqori voltli simlar subcontrol bo'shlig'ida tajovuzkor muhitga etarlicha chidamli bo'lishi kerak.

Ikkinchidan, ular haroratni +240 darajaga ko'tarishlari va harakatchan xususiyatlarini yo'qotmasliklari kerak.

Uchinchidan, simlar sham uchlariga ulanishdan oldin hozirgi oqishning oldini olish kerak. Noto'g'ri, past sifatli simlar, masalan, elektron tizim, shuningdek, motorning ishlashini murakkablashtirishi, shuningdek, elektr stantsiyasi "troit" ni boshlaydi.

Avtomobilni xavf ostiga qo'yadigan noto'g'ri simlar

Chidamlilik yoki hozirgi oqish pulsning kuchining pasayishiga olib keladi va oxiri yoki yo'qligini sekinlashtirish yoki yo'q qilish yoki umuman yo'qligi yoki yo'qligini sekinlashtirish Spark, ayniqsa shamda ozgina ifloslanish bo'lsa. Natijada dinamikaning pasayishi, egzoz va yoqilg'i sarfi (to'rtdan etti foiz) o'sib bormoqda.

Aheşy simlar, asosiy nosozliklar

Yuqori kuchlanishli sim bilan bog'liq asosiy muammo - bu etarli darajada kuchlanish natijasida yonish shamlari. Bunday nosozlikning sabablari:

  1. Yomon aloqa yoki uning yuqori voltli liniyalar va shamlar orasidagi mavjudligi.
  2. Yuqoridagi eng maqbul qarshilik.
  3. Yomon izolyatsiya sifati natijasida kuchlanish oqishi.
  4. Siqish kabellari izolyatsiyasi.

Yuqori kuchlanishli simlar yirtilganida elektr tushirilgan elektr oqimi amalga oshiriladi, bu erda kuchlanishning yo'qolishi sodir bo'ladi. Natijada, elektromagnit pulse allaqachon shamga berilib, ulangan kuchlanish emas. Shikastlangan yuqori kuchlanishli simlar dvigatelda o'chilgan ko'plab avtomobil sensorlarining noto'g'ri ishlashiga olib kelishi mumkin, chunki u har doim ham ishlamaydi, bunda u kamdan-kam hollarda ishlamaydi silindrlarni sinxronlashtiring.

Qanday qilib yuqori sifatli yuqori voltli simlarni tanlash, e'tibor berish

Yuqori voltli simlarni sotib olayotganda nafaqat brend va ishlab chiqaruvchining firmasi hisobga olinishi kerak. Motor modeliga alohida e'tibor berilishi kerak. Va bu avtomobillar dizaynida ishlab chiqaruvchilarning aniq simlarining aniq standartlarini belgilash yoki ta'mirlashda ko'rib chiqilishi kerak bo'lgan aniq belgilarni keltirib chiqaradi.

Kabel hisoblangan kuchlanishni tanlashning mezonlaridan biri bu kuchlanish hisoblanadi. Agar sim kuchlanishga turmasa, u holda izolyatsiyada bo'linishi mumkin, natijada sim amalga oshiriladi. Bundan tashqari, tanlanganda, kabel qilingan materialni hisobga olish kerak. Telefonning optimal moslashuvchanligi, shuningdek, yuqori harorat va kimyoviy faol materiallarning ta'siriga ega bo'lishi kerak.

Yuqori voltli multimetretri, bu qurilma nima va u qanday ishlaydi

Multimetr o'lchovlar uchun universal moslama (qarshilik, joriy, kuchlanish, parchalanish uchun simlarni tekshirish). Ushbu o'lchovlarning birortasi uchun maxsus vositalar qo'llanilishi mumkin, ya'ni Voltmetr, ampermetr, OhMmmetr. Kuchlanishni o'lchash uchun voltimetr ishlatiladi, hozirgi kuch asta-sekin o'lchanadi va omemetga qarshilikni o'lchash uchun ishlatiladi, ammo uversal qurilmasi ko'petrlik, uning printsipi kirish signallari bilan ma'lumotli signalni taqqoslash. Raqamli tipdagi multimetrik - ikki tomonlama integratsiya ADC.

Birinchidan, siz ko'rinadigan zarar (yoriqlar, yoriqlar va boshqalar) yuqori voltli simlarni tekshirishingiz kerak. Keyin siz asboblardan foydalanmasdan ham aniqlanadigan buzilish yo'qligiga ishonch hosil qilishingiz kerak. Qorong'idagi pumprompoom bo'sh joyiga qarash kifoya - yuqori voltli simdagi quvvat blokining ishlash jarayoni mavjud bo'lganda, uchqun ko'rinadi. Bundan tashqari, siz yuqori kuchlanishli sim yordamida siz ikkala tomondan tortib olingan simli sim bilan qurollangan holda olib tashlanishi kerak. Bundan tashqari, qorong'ida bir uchi mashinaning tanasida yopiq, ya'ni "massa" da yopiladi va biz yuqori voltli simlar, shuningdek, qopqoqlarning butun voltiqli simlardan boshqa perimetrni sarflaymiz. bo'g'imlar va boshqalar. O'sish joyida uchqun.

Ko'p miqdorda yuqori voltli simlarni qanday tekshirish kerak

  1. Modul rejimini yoqing.
  2. 1-chi silindrining shamidan, yuqori voltli sim va keyinchalik yonuvchan zilonadan olib tashlang.
  3. SIRning uchlariga ko'p miqdordagi elektrodlarni ulang va ko'rsatuvlarga qarang.

Yaxshi simlarda qarshilik simlarning turiga qarab 3,5-10 com chegaralarida farq qilishi kerak. Qarshilik ma'lumotlari ko'pincha simlarni izolyatsiya qilishda ko'rsatilgan.

Yuqori kuchlanishli simlarni tekshirish paytida hisobga olinishi kerak bo'lgan prof.

Har bir kabelni tekshirish kerak. Tarqabiyat ular orasida 2-4 komadan oshmasligi muhimdir. Agar tarqoq katta bo'lsa, simlarni almashtirish kerak. Aytgancha, simlar majmuada, ya'ni hamma birgalikda o'zgaradi.
