Icala 3: Isekethe eyinhloko yezigaba ezintathu zezimboni (igobolondo lepulasitiki i-MCCB)
Indawo: Isekethe enkulu yemoto engu-37kW, iSchneider NSX100N 3P
I-circuit breaker: Igobolondo lepulasitiki elinezingodo ezintathu, ububanzi besibambo bungu-25mm, akukho mbobo yokukhiya ejwayelekile
Ukukhetha: Ukuxhumanisa ukukhiya okunezinsika ezintathu (njengeLoko M-K24 / ETA X4230)
Isizathu sokukhetha:
Ukuxhumanisa isibambo esinezinti ezintathu ngesixhumanisi, ukuvimbela ukukhubeka ngengozi
Amandla amakhulu okubopha afanele isibambo esinzima se-MCCB, ukuvimbela ukuvulwa ngengozi
Isekela ukukhiya okuningi kwabantu abaningi, izidingo ze-LOTO zokugcinwa kwethimba ezihlangabezana nazo
Ukuthobela imithetho: Kuhambisana ne-IEC 60947-3, efanelekile kumasekethe ezimboni anamandla amakhulu
Ikesi 4: I-plastic plastic circuit breaker engenamigodi (ABB Tmax)
Indawo: Ikhabhinethi yokusabalalisa endaweni yamakhemikhali, i-ABB Tmax T1N 3P, isibambo esingenambobo yokukhiya, isikhala esincane
I-circuit breaker: Akukho mbobo yokukhiya, ukuhamba kwesibambo esifushane
Ukukhetha: Ilokhi yokubopha engenamigodi ezinikele (njenge-Badi 65680 / Master 495)
Isizathu sokukhetha:
Ukubopha okuvalwe ngokuphelele, okungathembeli emgodini wokukhiya, okufanele i-MCCB ekhethekile
Idizayini encane kakhulu, ifanele amakhabethe okusabalalisa afakwe kakhulu
Isakhiwo sokulwa nokukhethwa, ukuhlangabezana nezidingo zokuphepha eziphakeme zendawo yamakhemikhali
Ukuthobela imithetho: Ihlangabezana nezidingo zemvelo ezingaqhumi ze-ATEX, ifanele ama-circuit breaker aklanyelwe ngokukhethekile
Ikesi 5: Ikhabhinethi eyinhloko yegumbi lokusabalalisa (i-universal circuit breaker)
Indawo: I-1000A universal circuit breaker (DW45), ukulungiswa kwekhabhinethi yonke
I-circuit breaker： Uhlobo lwedrowa/I-universal circuit breaker elungisiwe, umnyango wekhabhinethi ungavulwa
Ukukhetha: Ilokhi yephaneli yomnyango weKhabhinethi + ilokhi yomzimba we-circuit breaker ephindwe kabili
Isizathu sokukhetha:
Ilokhi yephaneli ivala umnyango wekhabhinethi, ivimbela abasebenzi abangagunyaziwe ukuthi bangene
Ukukhiya umzimba okhiye ababili, kudinga okhiye ababili ukuvula, ukugadwa kwabantu ababili
Ukuvikelwa kwamazinga amaningi, ukuhlangabezana nezincazelo ze-LOTO zegumbi lokusabalalisa elinobungozi obukhulu
Ukuthobela imithetho: Ihlangabezana nemithethonqubo yokuphepha embonini yamandla, ifanelekela izifunda eziyinhloko ezingenayo / eziyinhloko ze-transformer
Icala 6: Ukulungiswa ngokubambisana (ukukhiya ngasikhathi sinye kwamasekethe amaningi)
Isimo: Ukuvalwa komugqa wokukhiqiza ukulungiswa okukhulu, amadivayisi ayi-10 anakekelwa ngasikhathi sinye, abantu abaningi basebenza
I-circuit breaker: Ama-MCB amaningi angawodwa/ama-pole amathathu + ama-MCCB axubile
Ukukhetha: Iziqeshana eziningi zokukhiya + ibhokisi lokukhiya elihlangene + izikhiya ezithile zesekethe
Isizathu sokukhetha:
Isekethe ngayinye ikhiywe ngokuzimela ngokukhiya ngakunye
Iziqeshana eziningi zokukhiya zisekela ukukhiya ngasikhathi sinye kwesekethe efanayo ngabantu abaningi
Ibhokisi lokukhiya elihlangene liphatha okhiye ngokulinganayo, ukuvula kudinga ukuqinisekiswa yibo bonke abasebenzi
