Ubufakazi bokuqhuma kwe-Shenhai
Izinto zikagesi ezingaqhumi zihlukaniswe ngezinhlobo ezimbili ngokusekelwe endaweni yemvelo yokusetshenziswa kwazo kwangempela: enye ngeyokusebenzisa izimayini kanti enye isetshenziswa efekthri. Kuye ngezici zemishini ekukhiqizeni izinhlansi, ama-arcs kagesi, kanye namazinga okushisa ayingozi, kanye nokuvimbela ukushiswa kwezinhlanganisela ezivuthayo, zihlukaniswe zibe izinhlobo eziyisishiyagalombili ezilandelayo:
1. Uhlobo lwe-Flameproof (imakwe 'd'):
Lolu uhlobo lwezinto zikagesi ezinendawo evalekile ekwazi ukumelana nokuqhuma kwezinhlanganisela zegesi evuthayo yangaphakathi nokuvimbela ukusabalala kokuqhuma kwezakhi ezizungezile ezivuthayo.. Ifanele zonke izindawo ezinengozi yokuqhuma.
2. Uhlobo Lokuphepha Olunyusiwe (imakwe 'e'):
Ngaphansi kwezimo zokusebenza ezijwayelekile, lolu hlobo lwesisetshenziswa cishe ngeke ludale ama-arc kagesi noma izinhlansi futhi ngeke lufinyelele amazinga okushisa akwazi ukuvutha ezivuthayo izinhlanganisela. Idizayini yayo ihlanganisa izinyathelo zokuphepha eziningi zokuthuthukisa izinga lokuphepha nokuvimbela ukudalwa kwama-arcs, izinhlansi, kanye namazinga okushisa aphezulu ngaphansi kwezimo zomthwalo ezivamile neziqashelwayo.
3. Uhlobo Oluphephile Ngaphakathi (kubhalwe ukuthi ‘ia’, 'ibe'):
Isebenzisa i-IEC76-3 ilangabi imishini yokuhlola, lolu hlobo luqinisekisa ukuthi izinhlansi kanye nemiphumela eshisayo ekhiqizwa ngaphansi kokusebenza okujwayelekile noma amaphutha ajwayelekile ashiwo akukwazi ukuthungela izinhlanganisela ezithile ezivuthayo.. Lawa madivayisi ahlukaniswe ngokuthi ‘ia’ kanye 'ib’ amazinga asekelwe ezindaweni zokufaka izicelo kanye namazinga okuphepha. ‘Iya’ amadivaysi ezinga ngeke akhele amagesi avuthayo ngaphansi kokusebenza okuvamile, iphutha elilodwa elivamile, noma amaphutha amabili avamile. ‘ibe’ amadivaysi ezinga ngeke akhele amagesi avuthayo ngaphansi kokusebenza okuvamile kanye nephutha elilodwa elivamile.
4. Uhlobo Olucindezelwe (imakwe 'p'):
Lolu hlobo lunendawo ebiyelwe enengcindezi egcina ingcindezi yangaphakathi ephezulu yegesi evikelayo, njengomoya noma igesi ye-inert, kunendawo yangaphandle evuthayo, ukuvimbela ama-compounds angaphandle ukuthi angangeni endaweni ebiyelwe.
5. Uhlobo Olugcwele Amafutha (kubhalwe ukuthi ‘U’):
Izinto zikagesi noma izingxenye zakhona zicwiliswa emafutheni ukuvimbela ukushiswa kwezinhlanganisela ezivuthayo ngaphezu kwezinga likawoyela noma ngaphandle kwendawo ebiyelwe.. Ama-circuit breaker kawoyela ane-voltage ephezulu ayisibonelo.
6. Uhlobo Olugcwele Isihlabathi (imakwe 'q'):
Indawo ebiyelwe igcwele isihlabathi ukuqinisekisa ukuthi noma yimaphi ama-arcs kagesi, izinhlansi ezihlakazekile, noma amazinga okushisa eqile odongeni oluvalekile noma endaweni yesihlabathi ngaphansi kwezimo ezithile zokusebenza awakwazi ukuthungela izinhlanganisela ezivuthayo ezizungezile.
7. Uhlobo Olungeyona Inhlansi (imakwe 'n'):
Ngaphansi kwezimo zokusebenza ezijwayelekile, lolu hlobo ngeke kokhele okuzungezile eziqhumayo inhlanganisela futhi ngokuvamile ayikhiqizi amaphutha avamile ngamakhono okuthungela.
8. Uhlobo Olukhethekile (imakwe 's'):
Lawa amadivayisi kagesi anezinyathelo ezihlukile zokuvikela ukuqhuma ezingaweli kunoma yiziphi izigaba ezishiwo ngenhla. Ngokwesibonelo, amadivaysi agcwele isihlabathi samatshe angaphansi kwalesi sigaba.
