Isigaba somthetho 1(Ububanzi)-Qaphela 1 Ukuhunyushwa kwenothi lendima yokuqala

Qaphela 1 njengoba ngezansi:
Abasebenzisa izinga bangase bacabange ukuthi izimfuneko zaleli zinga zinganakwa kulezo zinto zikagesi ezisebenza ngebhethri lapho kungekho khona ubungozi bokushaqeka kukagesi ngenxa yamandla kagesi aphansi ebhethri ngokwalo. Nokho, kusukela esimweni sangempela, lokhu akunjalo. Nakuba leli zinga ligxile ekuphepheni kukagesi komkhiqizo, liphinde ligxile ekutheni umkhiqizo unazo yini izingozi zemishini, ezishisayo, zomlilo, zamakhemikhali noma ezinobuthi. Ngisho noma kungekho monakalo kagesi, kungase kube nezinye izici eziyingozi ezikhona emkhiqizweni okusadingeka zihlolwe kusetshenziswa leli zinga. Ngaphezu kwalokho, eminye imikhiqizo esebenza ngebhethri, nakuba i-voltage yebhethri ngokwayo iphansi kakhulu, kuzoba nomjikelezo okhulayo ngaphakathi komkhiqizo, futhi i-voltage ethuthukisiwe isazoba yingozi emzimbeni womuntu, okusadingeka ukuthi kubhekwe njenge. imfuneko yokuphepha.

Isibonelo, Ifeni ephathwa ngesandla enikwe amandla ibhethri elishajekayo iveze ama-fan blade angafinyelelwa ngesandla ngqo. Nakuba ama-voltage okusebenza kokubili kwebhethri ne-fan motor ephansi, futhi i-fan blade ithambile; kusadingeka ukuhlola ukuthi ingabe noma iyiphi ingxenye ye-voltage yokusebenza yangaphakathi yomshini ingaphezulu kwaleyo yebhethri, futhi ngesikhathi esifanayo, ukuqina kwe-blade yefeni kungaphansi kwenani lomkhawulo elishiwo esilinganisweni.

For example, A handheld fan powered by a rechargeable battery has exposed fan blades that can be reached directly by hand. Although the operating voltages of both the battery and the fan motor are low, and the fan blade is soft; it is still necessary to check whether any part of the appliance’s internal operating voltage is higher than that of the battery, and at the same time, the hardness of the fan blade is less than the limit value specified in the standard.
