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 “protective electronic circuit”
Bygezhi-tech October 5, 2025October 5, 2025

protective electronic circuit: electronic circuit that prevents a hazardous situation under abnormal operating conditions.NOTE Parts of the circuit may also be used for functional purposes. With the advancement of technology, more and more electronic circuits are being used in household electrical products, and these electronic circuits are usually integrated on PCBs. They use microprocessor chips…

Isigaba sesi-3 – Iqondwa kanjani incazelo ye-“functional insulation”
Bygezhi-tech August 7, 2024September 27, 2025

i-functional insulation: ukwahlukanisa phakathi kwezingxenye ze-conductive zamandla ahlukene okudingeka kuphela ekusebenzeni kahle komshini. I-insulation esebenzayo isethwe ngenxa yezidingo zokusebenza zomshini. Emikhiqizweni kagesi, kufanele kube nezingxenye ze-conductive ezinamandla ahlukene (ama-voltage ahlukene). Uma i-voltage yawo wonke ama-conductor anamandla emkhiqizweni iyafana, into esetshenziswayo ayikwazi ukusebenza. Khona-ke, kukhona ukufakwa okusebenzayo phakathi kwezingxenye ezahlukene ze-conductive. Uma sicabanga ukuthi i-voltage elinganiselwe…

Isigaba sesi-3 – Iqondakala kanjani incazelo “yohlobo X, thayipha u-Y, uhlobo olunamathiselwe luka-Z”
Bygezhi-tech August 3, 2024September 27, 2025

Uhlobo lokuxhumana luchazwa ngumkhiqizi wohlelo lokusebenza. Ngokuvamile, akuvamile ukukuchaza njengohlobo X, ngoba lokhu kuzoletha ubungozi obungadingekile kumkhiqizi. Ivame ukuchazwa ngokuthi Uhlobo Y. Yebo, uma intambo yamandla isakazwa, ngokuvamile ichazwa ngokuthi Uhlobo Z. Umfanekiso olandelayo ubala imidwebo yokuxhuma yezinhlobo ezintathu zokunamathiselwe. Thayipha okunamathiselwe ku-X: ukuxhuma kwentambo yokuhlinzeka kuqedwa endaweni elungiselelwe ngokukhethekile entweni esetshenziswayo. Ngakho-ke, lapho ushintsha…

Clause 3 – How to understand the definition of “thermostat”
Bygezhi-tech December 22, 2024September 27, 2025

thermostat: temperature-sensing device, the operating temperature of which may be either fixed or adjustable and which during normal operation keeps the temperature of the controlled part between certain limits by automatically opening and closing a circuit. The thermostat itself does not control the temperature, the thermostat senses the temperature and controls the temperature by switching…
