Yuqori kuchlanishni o'chirishning asosiy funktsiyasi mavjud bo'lgan elektr uzatish funktsiyasi mavjud bo'lgan elektr uzatish funktsiyasini ochish va yuklash jarayoni yuqori darajada ko'rinishni taqiqlash va yuqori kuchlanishni uzatish stantsiyalari bilan ishlashni ta'minlash va yuqori kuchlanishni o'chirish stantsiyasini ishonchli tarzda amalga oshiring va unga yuqori kuchlanishni o'chirish stantsiyasi bilan ishonchli tarzda asoslash kerak 72 . 5 kV ~ 800kV tizimlari (126 kV darajasi odatiy benchmark).
The high voltage disconnect switch environment requires that the humidity be controlled at a relative humidity daily average value of<=80%, and the condensation risk area must be equipped with a constant temperature heating device (to prevent condensation on the surface of the insulation parts), and the pollution area of level III and above (salt density>=0.25mg/cm²) must use anti-fouling porcelain Kallycings va kreputat masofasi {{13} dan katta yoki unga teng bo'lsa, uning tekisligi 0,5 mm ga teng (Lazer balandligi) gorizontal xato, 8.8- kilometr m30 Qattiq quvvatli murvat, mahkamlash momenti 450 ~ 500ng · Mon (diagonali tartibda tortilgan), qo'llab-quvvatlash izolyatorining vertikallikning versiyasi 1 ° ga teng yoki tengdir.
Yuqori kuchlanishni o'chirish tugmachasini tugatgandan so'ng, besh himoya vositasi aloqalarini amalga oshiring, demak, o'chirgichni o'chirish yopilganda, uzilishni o'chirish taqiqlanadi (mexanik markazlashtirilgan tekshirish) taqiqlanadi; Er osti kaliti yopilganda, uzish o'chiruvchi (elektr markazlashtirilgan tekshirish) . .
Amaliyot ketma-ketligi: Quvvat buzgichi - Quvvatni ochish → Yuk o'chirish tugatish → Quvvatni uzatish; Elektr ta'minoti elektr ta'minoti bilan uzatish → Yuk o'chirish o'chirgich . a 15000 darajadan oshib ketishi va er osti qurilmasining ruxsat etilishi mumkin, bu esa . .
