Izolyatsiya vositalariga kirish

Izolyatsiya asboblari turli xil izolyatsiya tuzilmalariga ko'ra I, II va III toifalarga bo'linadi.

I sinf asboblari oddiy asosiy izolyatsiyaga ega bo'lgan elektr asboblariga tegishli. Elektr toki urishidan himoya qilish nafaqat ramining asosiy izolatsiyasiga tayanadi, balki xavfsizlik choralarini ham qo'shishi kerak, ya'ni tananing ochiq o'tkazuvchan qismi normal sharoitda zaryadlanmaydi, lekin uning asosiy izolyatsiyasi bo'lganda zaryadlangan tanaga aylanadi. shikastlangan himoyalangan va nolga ulangan. Ishonchli bo'lish uchun ikkita himoya noldan kam bo'lmasligi kerak va qo'shimcha qochqinning himoyasi qo'shilishi kerak. Shu bilan birga, operator izolyatsiyalovchi himoya vositalaridan foydalanishi kerak.

Class II tools refer to electric tools with double insulation or reinforced insulation. In terms of protection against electric shock, they not only rely on their basic insulation, but also have their live parts under normal conditions and accessible non-charged conductive parts. Double insulation or Strengthening insulation and isolation measures is equivalent to designing and manufacturing the operator's personal insulating protective equipment on the tool in a reliable and effective way.

III sinf asboblari xavfsizlik qoʻshimcha{0}}past kuchlanish bilan quvvatlanadigan elektr asboblarga tegishli boʻlib, elektr toki urishidan himoya qilish nuqtai nazaridan elektr taʼminoti uchun xavfsiz izolyatsiya transformatorlariga tayanadi.
