Ubufakazi bokuqhuma kwe-Shenhai
Ngokwemigomo yokwenyuka kokuphepha ekwakhiweni kokuvikela ukuqhuma, kunezidingo eziqondile zokuvikelwa kwekesi, ukufakwa kukagesi, uxhumano lwezintambo, ukucaciswa kukagesi, amabanga e-creepage, amazinga okushisa aphezulu, kanye namawindi emishini kagesi.
1. I-Casing Protection:
Ngokuvamile, izinga lokuvikelwa kwe-casing emishinini kagesi yokuphepha eyengeziwe limi kanje:
Ukuvikelwa kwe-IP54 okuncane kuyadingeka uma i-casing iqukethe izingxenye ezibukhoma eziveziwe.
Kudingeka ukuvikelwa kwe-IP44 okuncane uma i-casing iqukethe izingxenye ezibukhoma ezigqunyiwe.
Lapho amasekhethi ngokwemvelo aphephile noma amasistimu engaphakathi kwanda ukuphepha kwemishini kagesi, lezi zifunda kufanele zihlukaniswe kumasekhethi okungezona ngokwemvelo aphephile. Izifunda ezingenalo izinga lokuphepha elingokwemvelo kufanele zigcinwe ekhesejini enezinga lokuvikela okungenani le-IP30., enezimpawu eziyisixwayiso ezithi “Ungavuli uma ubukhoma!”
2. I-Insulation kagesi:
Ngaphansi kwezimo zokusebenza ezilinganiselwe nezimo ezivumelekile zokugcwala ngokweqile, ukusebenza okuphezulu izinga lokushisa ukuphepha okuthuthukisiwe kwempahla kagesi akufanele kuthinte kabi izakhiwo zemishini nezikagesi zempahla yokushisa. Ngakho-ke, ukumelana nokushisa nomswakama we-insulation material kufanele okungenani kube ngama-20K ngaphezu kwezinga lokushisa eliphezulu lokusebenza kwemishini, okungenani okungu-80°C.
3. Uxhumano Lwezintambo:
Ngoba ukwanda kokuphepha izinto zikagesi, izintambo zingahlukaniswa zibe izixhumanisi zangaphandle zikagesi (lapho izintambo zangaphandle zingena ku-casing) kanye nokuxhunywa kukagesi kwangaphakathi (ukuxhumana phakathi kwezingxenye ngaphakathi kwe-casing). Kokubili ukuxhumana kwangaphandle nangaphakathi kufanele kusebenzise izintambo eziwumgogodla wethusi noma izintambo.
Okokuxhumana kwangaphandle, ikhebula langaphandle kufanele lifake i-casing ngokusebenzisa idivayisi yokufaka ikhebula.
Okokuxhumana kwangaphakathi, zonke izintambo zokuxhuma kufanele zihlelwe ukuze zigweme izinga lokushisa eliphezulu kanye nezingxenye ezihambayo. Izintambo ezinde kufanele zilungiswe kahle endaweni. Izintambo zokuxhuma zangaphakathi akufanele zibe namalunga aphakathi.
Ukwengeza, ukuxhumeka kwentambo kuya kutheminali noma i-bolt-to-nut kufanele kuphephe futhi kuthembeke.
Ngokufigqiwe, ukumelana nokuxhumana ezindaweni zokuxhumana ngocingo kufanele kuncishiswe ukuze kugwenywe ukuba a “izinga lokushisa lengozi” umthombo wokuthungela; ukuxhumana okuxekethile kungabangela izinhlansi zikagesi ngenxa yokungathintani kahle.
4. I-Electric Clearance ne-Creepage Distance:
Imvume kagesi (ibanga elifushane emoyeni) kanye nebanga le-creepage (indlela emfushane eduze kobuso bempahla yokuvikela) ziyizinkomba ezibalulekile zokusebenza kukagesi kwemishini kagesi ephephile eyengeziwe. Uma kunesidingo, izimbambo noma ama-grooves anganezelwa ezingxenyeni zokuvikela ukuze kwandiswe imvume kagesi kanye nebanga le-creepage: izimbambo ezinobude obungu-2.5mm nobukhulu obungu-1mm; imisele enobubanzi obungu-2.5mm nobubanzi obungu-2.5mm.
5. Ukunciphisa izinga lokushisa:
Izinga lokushisa elilinganiselwe libhekisela ekushiseni okuphezulu okuvumelekile kwe izinto zikagesi ezingaqhumi. Izinga lokushisa eliphakeme lokushisisa lezingxenye zemishini kagesi evikelekile engase ihlangane nayo eziqhumayo izingxube zegesi ziyisici esibalulekile ekunqumeni ukusebenza kwazo okungaqhumi. Izinga lokushisa eliphakeme lokushisisa akufanele lidlule izinga lokushisa elikhawulelwe lempahla kagesi ephephile ekhuphukayo (isigaba sokushisa semishini yokuvikela ukuqhuma), njengoba kungase kuthungele ingxube yegesi eqhumayo ehambisanayo.
Lapho uklama izinto zikagesi ezingaqhumi eziphephile, ngaphezu kokucabangela ukusebenza kukagesi nokushisa kwezingxenye zikagesi, amadivaysi afanele okuvikela izinga lokushisa kufanele ahlanganiswe ukuze kuvinjelwe izingxenye ezithile ukuba zingeqi izinga lokushisa elilinganiselwe.
Ama-windings:
Ukwenyuka kwempahla kagesi ephephile njengamamotho, ama-transformer, ama-solenoids, nama-ballasts amalambu e-fluorescent wonke aqukethe ama-winding. Amakhoyili kufanele abe nezidingo zokushisa eziphakeme kunamakhoyili avamile (bheka izindinganiso zikazwelonke ezifanele) futhi kufanele ifakwe izinto ezivikela izinga lokushisa ukuvimbela amakhoyili ukuba angadluli izinga lokushisa elilinganiselwe ngaphansi kokusebenza okuvamile noma izimo zephutha ezishiwo.. Isivikeli sezinga lokushisa singafakwa ngaphakathi noma ngaphandle kwemishini futhi kufanele sibe nesihambisanayo uhlobo lokuvikela ukuqhuma.
