Isigaba sesi-3 – Uyiqonda kanjani incazelo ye-“rated impulse voltage”

Byforest
rated impulse voltage: I-voltage esuselwe ku-voltage elinganiselwe kanye nesigaba sokugcwala ngokweqile komshini, obonisa amandla okumelana ashiwo okufakwayo kwawo ngokumelene no-overvoltage wesikhashana.

Kwabaqalayo, akudingekile ngempela ukuqonda incazelo engokomzimba yale ncazelo. Ukusetshenziswa okuyinhloko kwaleli xabiso le-voltage esilinganisweni ukunquma inani elilinganiselwe lemvume; ngokubhekisela kuThebula 15, inani elilinganiselwe le-impulse voltage linganqunywa ngokuqondile.
Umusho ophezulu weThebula le-15 ubonisa ukuthi “Imishini ikusigaba II sokugcwala ngokweqile.”. Uma i-voltage elinganisiwe yomkhiqizo ingu-AC220-240V, ehambelana nomugqa wokugcina wamanani kukholamu yokuqala yeThebula 15, i-voltage ye-pulse elinganiselwe inqunywa ukuthi ingu-2500V.

Mangisho ukuthi isigaba se-overvoltage(OVC) siphuma ku-IEC 60664-1 ejwayelekile. Ithebula elingezansi lisinikeze incazelo.



Ngakolunye uhlangothi, kunomdwebo ochaza isigaba se-overvoltage(OVC).
