Isigaba sesi-3 – Iqondwa kanjani incazelo “yebanga lefrikhwensi elinganiselwe”

Bygezhi-tech July 14, 2024September 27, 2025

ibanga lefrikhwensi elinganisiwe: ibanga lefrikhwensi elinikezwe umshini ngumkhiqizi, ovezwa imikhawulo yawo ephansi nangaphezulu.

Ngakho-ke, ngincoma ukuthi umake imvamisa elinganiselwe njengo-50/60Hz ngokuqondile.
Therefore, I recommend marking the rated frequency as 50/60Hz directly.

Isigaba sesi-3 – Iqondwa kanjani incazelo “yefrikhwensi elinganiselwe”
Bygezhi-tech July 14, 2024September 27, 2025

isilinganiso esilinganiselwe: imvamisa eyabelwe into esetshenziswa umkhiqizi. Ngokuvamile, imvamisa elinganiselwe imvamisa yokusetshenziswa okujwayelekile yezwe lemakethe eliqondiwe ngesikhathi umkhiqizo uklanywa. Njengoba emhlabeni wonke, kukhona amaza okusebenza amabili kuphela, i-50Hz kanye ne-60Hz, inani lingaba ngu-50Hz noma u-60Hz kuphela, noma womabili u-50 kanye no-60Hz. Imvamisa elinganiselwe, amandla amanje alinganiselwe noma alinganiselwe, i-voltage elinganiselwe, njll. amapharamitha ayisisekelo abonisa into…

Isigaba sesi-3 – Uyiqonda kanjani incazelo ye-“rated impulse voltage”
Bygezhi-tech July 15, 2024September 27, 2025

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…

Isigaba sesi-3 – Iqondwa kanjani incazelo “yensiza yekilasi 0I”
Bygezhi-tech August 11, 2024September 27, 2025

Into esetshenziswayo yekilasi 0I: into esetshenziswayo enokufakwa okungenani okuyisisekelo kuyo yonke indawo futhi ehlanganisa itheminali yomhlaba kodwa enentambo yokuhlinzeka ngaphandle kwe-conductor yomhlaba kanye nepulaki ngaphandle kokuthintana komhlaba. Into esetshenziswayo inetheminali yokuxhuma i-conductor yangaphandle evikelayo (ikhondaktha yomhlaba ovikelayo), kodwa ayikho intambo yokuxhuma into esebenza ekhondathani eyisivikelo ezintamboni ezingaguquki, into esetshenziswayo ingase ibe nentambo noma isakhiwo ngaphakathi…

Clause 3 – How to understand the definition of “heating appliance”
Bygezhi-tech October 19, 2024October 7, 2025

heating appliance: appliance incorporating heating elements but without any motor. Before introducing this definition, we need to briefly introduce the electric heating elements commonly used in household electrical appliances. PTC heating element: PTC (Positive Temperature Coefficient) heating elements are widely used for various heating applications because of their self-regulating properties and safety features. Here are…
