Ukuvikelwa komehluko wemoto kumelela indlela eyisisekelo yokuphepha, esetshenziswa kakhulu kumongo wezinjini eziphakathi nezinkulu ezisebenza ngaphakathi kwamagridi ane-voltage ephezulu. Lolu hlelo lokuvikela lubaluleke kakhulu ekuqinisekiseni ukuthembeka nokusebenza kahle kokusebenza kwemoto, njengoba lubonisa ikhwalithi yemisebenzi yangaphakathi yemoto. Ngokuqapha amanani wamanje okusebenza ekuqaleni nasekupheleni kokugoqa kwemoto, ukuvikelwa komehluko kungabona ngempumelelo noma yikuphi umehluko ongabonisa iphutha elingase libe khona.
Isizathu esiyinhloko sokusetshenziswa kokuvikelwa okuhlukile kwe-high-voltage enkulu kanyeinjini esebenza kahle kakhulus yikhono layo lokwenza kube lula ukuthola amaphutha ngokushesha nangokunembile. Ama-motor ane-voltage ephezulu avame ukuba yingxenye yezinqubo zezimboni kanye nokukhiqizwa kwamandla, ngakho-ke ukusebenza kwawo okungaphazanyiswa kubaluleke kakhulu. Ukwenzeka kwephutha langaphakathi, njengokuphazamiseka kwesekethe noma ukwehluleka kokufakwa kokushisa, kungabangela ukwehluleka okukhulu, okungaholela ezindlekweni ezinkulu maqondana nesikhathi sokungasebenzi kanye nomonakalo omkhulu. Uhlelo lokuvikela oluhlukile lwenzelwe ukuqhathanisa njalo ukungena nokuphuma kwamanje kwemoto. Uma kwenzeka ukuthi ukungafani kudlula umkhawulo osungulwe ngaphambilini, idivayisi yokuvikela ivuselelwa ngokuzenzakalelayo, ngaleyo ndlela ihlukanise imoto nomthombo wamandla futhi ivimbele ukuwohloka okuqhubekayo.
Ngaphezu kwalokho, ukwakheka okuyinkimbinkimbi kanye nobukhulu obukhulu balezi zinjini ezinkulu kudinga ukusetshenziswa kwezindlela zokuvikela eziqinile. Ukusebenza kwalezi zinjini ngaphansi kwezimo zomthwalo ezahlukahlukene kungenza inqubo yokuthola amaphutha ibe nzima. Ukusebenza kahle kokuvikelwa okuhlukile kusekukwazini kwayo ukuhlukanisa phakathi kokushintsha okuvamile kokusebenza kanye namaphutha angempela, ngaleyo ndlela kuqinisekiswe ukuthi yizinkinga zangempela kuphela ezibangela impendulo yokuvikela. Lokhu kunemba kunciphisa ukuphazamiseka okungadingekile futhi kuthuthukisa ukuthembeka okuphelele kohlelo.
Uma kuqhathaniswa nezinjini ezincane neziphakathi nomai-ac motor enamandla aphansi, ama-motor ane-voltage ephezulu ayabiza futhi anezicelo ezibalulekile nezikhethekile. Kokubili ukulahlwa komzimba we-motor ngemva kokwehluleka kanye nezinye izinkinga ezitholakala ngenxa yokwehluleka kungaba kubi kakhulu kunalokho esingakucabanga. Ngenxa yalesi sizathu, kuzosetshenziswa ezinye izikhathi ezikhethekile ezisetshenziswa kuma-motor ane-voltage ephezulu, amadivayisi okuvikela umehluko, inhloso yawo iwukuthola izinkinga ngesikhathi nangempumelelo nokuvimbela ukuwohloka okuqhubekayo kwenkinga.
Uma kunjalo, ukusetshenziswa kokuvikelwa okuhlukile kwezingxenye ezinkuluimoto yokungenisa ene-voltage ephezulu enezigaba ezintathuKubalulekile, hhayi nje isinyathelo sokuqapha; kubalulekile ekugcineni ukuzinza nokusebenza kahle. Ukuvikelwa okuhlukile kubalulekile ekuvikeleni ama-motor kanye nenethiwekhi kagesi ebanzi ngokwenza kube lula ukuhlonza amaphutha ngokushesha nokunciphisa amathuba okuphuka okubi.
