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.

Clause 3 – How to understand the definition of “PTC heating element”
Bygezhi-tech December 11, 2024October 4, 2025

PTC heating element: element intended for heating consisting mainly of positive temperature coefficient resistors that are thermally sensitive and have a rapid non-linear increase in resistance when the temperature is raised through a particular range. As the temperature increases, the resistance of the heating element of the PTC heating element increases. The relationship between temperature…

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…

Clause 3 – How to understand the definition of “self-resetting thermal cut-out”
Bygezhi-tech December 23, 2024September 27, 2025

self-resetting thermal cut-out: thermal cut-out that automatically restores the current after the relevant part of the appliance has cooled down sufficiently In the definition there is a clear mention, when the temperature is cooled to a certain degree, in fact, its intention is to control the temperature is not too high, when the temperature is…

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 – Uyiqonda kanjani incazelo “yesiguquli esihlukanisayo sokuphepha”
Bygezhi-tech September 5, 2024September 27, 2025

i-transformer yokuphepha ehlukanisayo: i-transformer, okokufaka okujikajikayo okuhlukaniswa ngogesi kusukela ekujikeni kokuphumayo ngesimbobo okungenani esilingana nokufakwa okuphindwe kabili noma ukwahlukanisa okuqinisiwe, okuhloselwe ukunikeza into esetshenziswayo noma isekethe ku-voltage ephephile ephansi kakhulu I-transformer okukhulunywe ngayo lapha isetshenziselwa ukuhlinzeka ngamandla ezintweni ezisetshenziswayo noma kumasekhethi. Ama-transformer amaningi ajwayelekile ahlinzeka ngamandla kumasekhethi, futhi ambalwa anikezela ngamandla ezintweni zikagesi. Okubalulekile lapha…
