Ukuvikelwa kwemoto: ukuqinisekisa impilo nokusebenza kahle kwezinhlelo zikagesi
Ezweni lobunjiniyela kagesi, ukuvikelwa kwezimoto kuyisici esibalulekile esingenakunakwa. Ama-motor ayinsika yezinhlelo zokusebenza eziningi zezimboni nezentengiselwano, anika amandla yonke into kusukela kumabhande okuhambisa kuya ezinhlelweni ze-HVAC. Kodwa-ke, lezi zingxenye ezibalulekile zingase zibe nezinhlobo ezahlukene zomonakalo, okuholela esikhathini sokungasebenzi esibizayo kanye nokulungiswa. Ngakho-ke, ukuqonda nokusebenzisa isu lokuvikela izimoto eliphumelelayo kubalulekile ekugcineni ukusebenza kahle kanye nokwandisa impilo yemoto.
Qonda Ukuvikelwa Kwezimoto
Ukuvikelwa kwezimoto kubhekisela ezinyathelweni namadivayisi athathwayo ukuvikela izimoto ezingozini ezingaba khona ezingabangela ukwehluleka. Lezi zingozi zifaka phakathi ukugcwala ngokweqile, i-short circuit, ukungalingani kwesigaba, kanye nezici zemvelo ezifana nomswakama nothuli. Ngokusebenzisa ubuchwepheshe bokuvikela izimoto, abaqhubi bangavimbela umonakalo, banciphise izindleko zokulungisa, futhi bathuthukise ukuthembeka okuphelele kohlelo.
Uhlobo lokuvikela imoto
1. Ukuvikelwa komthwalo oweqile: Enye yezinsongo ezivame kakhulu ezinjinini ukulayisha ngokweqile, okuwukwehluleka okwenzeka lapho injini ibhekene nomthwalo oweqile umthamo wayo olinganiselwe. Amadivayisi okuvikela umthwalo oweqile, njenge-thermal overload relay, aklanyelwe ukubona ugesi oweqile futhi akhiphe imoto kugesi ngaphambi kokuba yonakale. Lokhu kuvikelwa kubalulekile ekuvimbeleni imoto ekushiseni ngokweqile nokuqinisekisa ukuthi imoto isebenza ngaphakathi kwebanga eliphephile.
2. Ukuvikelwa kwesekethe emfushane: Isekethe emfushane ingabangela umonakalo omkhulu ezinjinini nasemishinini ehlobene nayo. Ama-circuit breaker nama-fuse avame ukusetshenziselwa ukuhlinzeka ngokuvikelwa kwesekethe emfushane. Lawa madivayisi angabona ukujiya kwamanje okungazelelwe futhi anqume ugesi, ngaleyo ndlela avimbele umonakalo omkhulu enjinini futhi anciphise ingozi yomlilo.
3. Ukuvikelwa kokulahlekelwa yisigaba: Ama-motor avame ukunikezwa amandla kagesi wezigaba ezintathu. Ukulahlekelwa yisigaba esisodwa (okungukuthi, ukungabikho kwesigaba esisodwa) kubangela ukungalingani kwamandla kagesi, okungabangela ukuthi imoto ishise ngokweqile futhi ekugcineni kubangele ukuthi imoto yehluleke. I-phase loss relay iqapha izinga lamandla kagesi wesigaba ngasinye futhi inqamule imoto lapho kutholwa ukungalingani, ivikele imoto ekulimaleni okungenzeka.
4. Ukuvikelwa kwemvelo: Ama-motor avame ukuchayeka ezindaweni ezinzima, okuhlanganisa uthuli, umswakama, kanye namazinga okushisa aphezulu. Izilinganiso zokuvikelwa kwezimo ezithile zemvelo, njengezilinganiso ze-IP (Ingress Protection), zingasiza ekuvikeleni ama-motor kulezi zinto. Ngaphezu kwalokho, ukusebenzisa izinhlelo zokungenisa umoya ezifanele kanye nokupholisa kungathuthukisa kakhulu ukuvikelwa kwe-motor ezindaweni ezinzima.
Ukubaluleka Kokunakekelwa Okuvamile
Nakuba izivikelo zezimoto zibalulekile, azithathi indawo yokulungiswa okuvamile. Ukuhlolwa okuvamile nokulungiswa kokuvimbela kungabona izinkinga ezingaba khona ngaphambi kokuba zibe yizinkinga ezinkulu. Lokhu kuhlanganisa ukuhlola izimpawu zokuguguleka, ukuqinisekisa ukugcotshwa okufanele, kanye nokuqapha ukuxhumana kukagesi. Ngokulondoloza imoto kanye nesivikelo sayo, abaqhubi bangaqinisekisa ukusebenza kahle kanye nobude besikhathi.
Umugqa Ophansi
Ngamafuphi, ukuvikelwa kwezimoto kuyisici esiyisisekelo sezinhlelo zikagesi futhi kudlala indima ebalulekile ekuqinisekiseni ukuthembeka nokusebenza kahle kwezinjini. Ngokusebenzisa amasu ahlukahlukene okuvikela, okuhlanganisa ukulayisha ngokweqile, ukuvikelwa kokulahlekelwa yi-short circuit kanye ne-phase, kanye nokucabanga ngezinto zemvelo, abaqhubi bangavikela izinjini ezingozini ezingaba khona. Ngaphezu kwalokho, ukulungiswa njalo kubalulekile ukuze kuhambisane nalezi zinyathelo zokuvikela ukuqinisekisa ukuthi izinjini ziyaqhubeka nokusebenza kahle nangokushelela. Njengoba izimboni zincika kakhulu ezinjinini, ukutshala imali esu lokuvikela izinjini eliqinile kuzohlinzeka ngezinzuzo ezibalulekile maqondana nokusebenza kahle, ukonga izindleko kanye nokuqhubeka kokusebenza.
