Isigaba sesi-3 – Iqondwa kanjani incazelo ye-“basic insulation”
isisekelo se-insulation: kanye ne-nbsp;i-insulation isetshenziswa ezingxenyeni eziphilayo ukuze kunikeze isivikelo esiyisisekelo ngokumelene nokushaqeka kukagesi
Njengoba kukhonjisiwe esithombeni esingakwesokunxele ngezansi, isithombe sekhava engezansi yefeni, futhi isithombe esingakwesokudla isithombe esingenayo ikhava engezansi. Isikhumba socingo oluluhlaza nolunsundu ngaphakathi kwentambo yokuhlinzeka esithombeni esilungile singabhekwa njengokwahlukanisa okuyisisekelo. Ngesikhathi esifanayo, izikhumba zocingo ezimhlophe, ezibomvu nezimnyama ekushintsheni okuxhunywe kugobolondo elimnyama nazo zingahlulelwa njenge-insulation eyisisekelo; izingxenye ezibukhoma lapha ziyingqikithi yethusi ocingweni. Ngaphezu kwalokho, ibanga eliphakathi kwe-conductor yensimbi ekushintsheni kanye nendawo yangaphakathi yegobolondo elimhlophe lingahlulelwa njengokugxilwa okuyisisekelo. Ngokombono webanga le-creepage, ugesi ku-conductor ongaphakathi kwe-switch wenziwa (ukhuphuka) eduze kwendawo yokushisa ye-switch endaweni yangaphakathi yegobolondo elimhlophe (ekhoneni elincane lesobunxele lesithombe esingakwesokudla), futhi leli banga lingakwazi. kubhekwe njengebanga elidala le-insulation eyisisekelo. Ngokombono we-electrical clearance, ugesi ku-conductor ngaphakathi kwesishintshi uqhutshwa ngokuqondile emoyeni phakathi kwendawo yangaphakathi yekhava engezansi ye-fan kanye negobolondo lokushintsha, futhi leli banga phakathi komoya libhekwa njengokuvunyelwa kwe-insulation eyisisekelo. (Igobolondo lepulasitiki elimhlophe lahlulelwa njenge-insulation eyengeziwe)
Njengoba kukhonjisiwe emfanekisweni ongezansi, kanye naku-nbsp;intambo evunguzayo yenjini ayilungiswanga kahle futhi iseduze kakhulu ne-motor stator. Ngeke isakwazi ukuhlangabezana nebanga elidala kanye nezidingo zebanga lokuvunyelwa zesigatshana somthetho 29. Lena into evamile yokungalandeli.
Njengoba kukhonjisiwe esithombeni esigqwayizayo ngezansi, umugqa wesihloko somcibisholo obomvu uphawula indawo yokwahlukanisa okuyisisekelo, okuhlanganisa ukuphuma kanye nomzila webanga le-creepage. Amawindi e-reactor asetshenziswa kuma-air conditioner ayizingxenye ezibukhoma, futhi ama-windinging ahlukaniswa ne-stator core nge-bobbin, eyakha i-insulation eyisisekelo.

As shown in the animated image below, the red arrowhead line marks the location of the basic insulation, including clearance and creepage distance path. The windings in the reactor used in air conditioners are live parts, and the windings are separated from the stator core by bobbin, which forms the basic insulation.

Njengoba kukhonjisiwe esithombeni esingakwesokunxele ngezansi, isithombe sekhava engezansi yefeni, futhi isithombe esingakwesokudla isithombe esingenayo ikhava engezansi.
