Ukuthenga ngaphakathi nohlelo

Mayelana nalolu hlelo lokusebenza

Isofthiwe Arc Flash ahlaziye lakhiwe okusekelwe IEEE 1584 Umhlahlandlela sokwenza Arc-Flash Hazard Izibalo njengoba ithuluzi elula ukuyisebenzisa futhi olubanzi ukubala sigameko amandla arc flash nomngcele, yokunquma okulinganiselwe, kuvinjelwe, kungavunyelwe ndlela imingcele kanye ingozi ingozi isigaba kudingwa NFPA 70E, NEC / CEC and Osha lapho umsebenzi okumele kwenziwe noma eduze imishini okunomdlandla.

I model IEEE 1584 empirically elisuselwa ikhethwe for arc flash ukuhlaziya ngenxa ukwazi le oyisibonelo sika ukuze ngokunembile akhawunti ezihlukahlukene isethaphu nemingcele kufaka:

* Imishini ovulekile kanye nebhokisi ukucupha
* Isisekelo yabo bonke izinhlobo kanye ungrounded
* Igebe esiphakathi babashayeli of mm 3 kuya 152.
* Short imisinga wesifunda ngo ekupha 700A kuya 106kA
* Line uhlelo voltages in ekupha 208V kuya 15kV
* Amabanga ukusebenza kusuka intshi angu-10 kuya 80

Ngokuba Ezimweni lapho voltage uphezu 15kV noma igebe zingaphandle ekupha imodeli, lo kwakuthiwa elisuselwa Lee indlela singasetshenziswa futhi kufakwe iAFA V1.0

Isofthiwe arc flash uthatha imishini ukumisa, igebe phakathi electrode, isisekelo hlobo, okufutshane amaphutha wesifunda value wamanje kanye system voltage on zolimo, futhi inquma arcing fault wamanje engxenyeni engaba khona of amaphutha.

Ukuze Amadivayisi zokuzivikela ezisebenza engxenyeni emaweni yesikhathi-zamanje sabo Curves, ushintsho encane zamanje kubangela ushintsho enkulu efanayo isikhathi ukusebenza. Sigameko energy is lwento ngokuhamba kwesikhathi, futhi ngenxa yalokho ARC Izinguquko zamanje ingase ibe nethonya elikhulu sigameko energy. Ikhambi ehlongozwayo IEEE 1584 ukwenza ezimbili arc zamanje namandla izibalo: eyodwa besebenzisa kulowo ebalisisiwe kulindelwe arc zamanje futhi besebenzisa anginciphisele arc lwamanje elingaphezu 15% ephansi.

Isofthiwe arc flash kwenza izibalo ze bobabili amacala ngazo ngenhla. I iAFA software arc flash ubikezela arcing fault zamanje okwesikhathi ukumiswa owanikwa kanye nenani le-etholakalayo 3-Isigaba circuit iDemo bamanje. Okulandelayo, ama-energy sigameko, arc flash emngceleni, ukuvikelwa shock imingcele kanye izinga nabasebenzi imishini zokuzivikela bazimisele asekelwe imishini ukumisa, ekhethiwe umfula ukuvikelwa idivayisi izilinganiso kanye nebanga zokusebenza.

Izinzuzo:

* Ukuhlaziywa okuningiliziwe besebenzisa i-IEEE 1584 zibalo kanye indlela Lee
* Qoqa ulwazi, thatha izithombe switchgear, njll MCC ngesikhathi inkundla ukuhamba-kwezimo
* Ngokushesha linqume zamanje arcing, sigameko energy, arc kweso, elinganiselwe, kuvinjelwe, kungavunyelwe ndlela imingcele, ingozi ingozi isigaba, esivamile izingubo uhlelo
* Engeza fuse kanye circuit idatha full kufaka isikhathi zamanje izici ze le amadivaysi ukuthi ingangeni kakade iyavela wezincwadi device esakhelwe in ukuvikelwa
* Calculator-isitayela oluchazayo kwenza izibalo eziyinkimbinkimbi lula ukukuqonda
* Ukuhlinzeka indawo ephephile ukusebenza ngokubhalisa izinga kahle siqu imishini zokuzivikela. Ukugqoka izingubo singenele kuyingozi ngenxa yezizathu ezisobala, kodwa ukugqoka izembatho ngokweqile kuyingozi ngenxa ukuhamba elinganiselwe futhi ukubonakala
* Klama ephephile amandla izinhlelo ngenkathi insuring ukuhambisana NEC 110,16, Osha, NFPA 70E, IEEE P1584 kanye namazinga CSA Z462 neziqondiso
* Gwema izinhlawulo ezingase zivele, ukukhiqiza elilahlekile, futhi yanda umshuwalense kanye icala izindleko
* Hlela arc isikhathi ukunquma-off in the uhla lwesibili 2 kuya ku-10
* Linganisa IThreshold Isigameko Energy for a Wesibili Degree Burn
* Qalisa arc amalebula flash isixwayiso in isinqumo high format graphic
* Yakha amalebula eziyisixwayiso ngesiNgisi kanye ezihlukahlukene izilimi international
* Gcina ukucupha zolimo, imishini image ukuze zisetshenziswe esikhathini esizayo
* Thumela umbiko enwetshiwe kubandakanya idatha imishini, ukubala imiphumela, arc flash ilebula
* Yenza Ukuhlaziywa ngekusebentisa imethrikhi, amayunithi lombusi
