Yintoni iCable ekhuselekileyo ngaphakathi?
- Intshayelelo: Yintoni iCable ekhuselekileyo ngaphakathi?
I-Anintambo ekhuselekileyo ngokwangaphakathi (IS)yintambo eyenzelwe ukusebenza kwiindawo ezinobungozi (eziqhumayo) ngaphandle komngcipheko wokutsha.
Inkcazo Esemthethweni (IEC 60079-11):Isekethe ekhuselekileyo ngokwemvelo yenye"apho naluphi na uhlaselo okanye isiphumo sobushushu singenakubangela ukutsha komxube wezinto ezinokutsha okanye ezinokutsha emoyeni phantsi kweemeko zovavanyo ezimiselweyo."
Ngamagama alula:Intambo ye-IS, xa iqhagamshelwe kwisithintelo esifanelekileyo sokunciphisa amandla, ithwala amandla amancinci ombane kangangokuba ne-short circuit okanye i-wire ephukileyo ayinakuvelisa i-spark eshushu ngokwaneleyo ukuba ivuthele iigesi ezivuthayo ezijikelezileyo, umphunga, okanye uthuli.
Umahluko Obalulekileyo:
| Indlela yoKhuselo | Ingaba isebenza kanjani | Indima yeCable |
| Ukuthintela Ukuqhuma (Ngaphandle ko-d) | Ukuvalwa okunzimaiquletheukuqhuma | Intambo ingena nge-gland engatshiyo; intambo ngokwayo isenokuba yeyomgangatho oqhelekileyo |
| Ukhuseleko lwangaphakathi (Ex-i / IS) | Ukunqongophala kwamandlakuthintelaukuqhuma | Intambo kufuneka ibe neeparameter zombane ezilawulwayo (i-Cc/Lc ephantsi) |
(IsiNgesi)Umzobo wenkqubo ekhuselekileyo ngaphakathi）
KwiDingzun Cable,Iintambo zethu ezikhuselekileyo ngokwemvelo zenziwe ngokweemfuno ze-IEC 60079-11, eziquka ulwakhiwo olune-capacitance ephantsi/u-inductance ephantsi kunye ne-sheathing ekhanyayo-eluhlaza okwesibhakabhaka enyanzelekileyo ukuze kuthotyelwe indawo enobungozi.
- Isebenza njani iCable ekhuselekileyo ngaphakathi?
Intambo ekhuselekileyo ayisebenzi yodwa. Iyinxalenye yesiqinisekisoInkqubo ye-ISequlathe izinto ezintathu:
Itheyibhile 1: Izinto Ezintathu Eziyinxalenye Yenkqubo ye-IS
| Icandelo | Indawo | Umsebenzi | Umzekelo |

Umgaqo Wokuncitshiswa Kwamandla:
- Iimfuneko eziphambili zeeCables eziKhuselekileyo ngaphakathi
Ayizizo zonke iintambo ezinokusetyenziswa kwinkqubo ye-IS. I-IEC 60079-14 kunye ne-NFPA 70 zichaza iimfuno eziyimfuneko.
Itheyibhile 2: Iimfuno zeCable eziKhuselekileyo ngaphakathi
| Imfuneko | Inkcazo | Umgangatho woMthombo | Isizathu Sokuba Kubalulekile |
| Ukunqongophala kwamandla | Intambo mayihlukaniswe kwiisekethe ezingezizo eze-IS | I-IEC 60079-14 | Ithintela ukufuduka kwamandla okuyingozi |
| Ubungakanani bomthamo (Cc) | Umthamo osasazwe kancinci (≤150 nF/km eqhelekileyo) | I-IEC 60079-14 | Iintambo zigcina amandla; itshaja egciniweyo iphuma njengentlantsi xa ifutshane |

| Umqhubi | Ubhedu olunezinti (Udidi 5/6) | IEEE 1580 | Ukuguquguquka kunye nokumelana nokungcangcazela |
KwiDingzun Cable,Iintambo zethu ze-IS ziyahlangabezana nazo zonke ezi mfuneko: i-Cc/Lc ephantsi, ukhuselo lwe-copper braid olufakwe kwi-tin, ii-conductors ze-copper ezifakwe kwi-tin ezixineneyo, kunyeizikhonkwane zangaphandle ezikhanyayo neziluhlaza okwesibhakabhaka (RAL 5015)ngokwe-IEC 60079-14.
- Ikhowudi yoMbala oLuhlaza okwesibhakabhaka: Kutheni iintambo ziluhlaza okwesibhakabhaka
Kwihlabathi liphela, iintambo ezisetyenziselwa iisekethe ezikhuselekileyo ngokwemvelo kufuneka zichongwe yi-isikhongozeli sangaphandle esiluhlaza okwesibhakabhaka(RAL 5015) ngokwe-IEC 60079-14.
Kutheni ukuCodesha imibala kubalulekile:
| Khupha | Isiphumo sokungawunaki uMthetho woMbala |
| Uqhagamshelo ngengozi lwamandla angengowase-IS | Ingcali ingaqhagamshela isekethe yamandla ye-120V AC kwibhloko yesiphelo se-IS, yoyise umqobo wokhuseleko kwaye idale ingozi yokuqhuma |
| Ukudideka kokugcinwa | Ngaphandle kokubonwa ngamehlo, iingcali zombane zinokucinga ukuba isekethe ikhuselekile xa ingekho |
| Ukungathobeli imithetho | Abahloli-zincwadi baza kuphawula iisekethe ze-IS ezingezizo eziluhlaza okwesibhakabhaka njengokwaphulwa komthetho, nto leyo enokuvala imisebenzi |
Iimfuneko zokuthobela imithetho:
| I-elementi | Imfuneko |
| Intambo engaphandle kwesingxobo | Oluhlaza okwesibhakabhaka (RAL 5015) |
| Ukumakishwa kwentambo | Uphawu oluhlala ixesha elide oluthi "Ex-ia" okanye "Ex-ib" |
| IiTerminali | Iitheminali okanye iisleeve eziluhlaza okwesibhakabhaka |
| Iinkqubo zemibhobho | Umjelo oluhlaza okwesibhakabhaka okanye ilebheli ethi "Intrinsically Safe" |
Isilumkiso:Ukuba i-cable sheath yakho imnyama, ingwevu, okanye nayiphi na imibala ngaphandle kombala oluhlaza okwesibhakabhaka, ayilunganga.ayithobeli imithethokwiisekethe ze-IS ngokwe-IEC 60079-14—kungakhathaliseki ukusebenza kwayo ngombane.
(IsiNgesi)Intambo ekhuselekileyo ngaphakathi）
KwiDingzun Cable,Iintambo zethu ze-IS zine-isigqubuthelo sangaphandle se-LSZH esikhanyayo (RAL 5015)ngophawu oluqinileyo lwe-Ex-ia/Ex-ib, ukuqinisekisa ukuthotyelwa kweendawo ezinobungozi ngoko nangoko.
- Iiparameter zoMbane: I-Capacitance (Cc) kunye ne-Inductance (Lc)
Intambo ngokwayo igcina amandla ombane ngeendlela ezimbini. La mandla agciniweyo anokukhululwa njengentlantsi ngexesha lempazamo (i-short circuit okanye i-open circuit). Intambo ye-IS eqinisekisiweyo kufuneka ibe nayoiphantsi kwaye ibhalwe phantsiAmaxabiso e-Cc kunye ne-Lc.
Itheyibhile 3: Kutheni i-CC kunye ne-LC zibalulekile kukhuseleko lwangaphakathi
| Ipharamitha | Isimboli | Oko Kumeleyo | Umngcipheko | Imfuneko ye-IS |
| Ubungakanani bomthamo | I-Cc (nF/km) | Intambo isebenza njenge-capacitor, igcina itshaja yombane phakathi kwabaqhubi naphakathi komqhubi kunye nekhaka | Xa incitshisiwe, itshaja egciniweyo iphuma njengentlantsi.Amandla aphezulu = intlantsi enkulu = umngcipheko ophezulu wokutsha | Iphantsi(≤150 nF/km eqhelekileyo) |
| Ukungenisa | I-Lc (µH/m okanye i-mH/km) | I-cable loop igcina amandla emagnethi kwintsimi yemagnethi ejikeleze ii-conductors | Xa ivuliwe, i-magnetic field ewayo ivelisa i-voltage spike enokwenza i-spark | Iphantsi kwaye ilawulwa(≤0.8 mH/km eqhelekileyo) |
| Umlinganiselo we-L/R | I-L/R (µH/Ω) | Ixesha elingaguqukiyo lesekethe; linxulumanisa amandla emagnethi agciniweyo nokumelana | Isetyenziselwa isiqinisekiso sentambo yokwemba (BS 6704) | Kufuneka ihambelane neenkcukacha zomqobo |
Ingcamango yeQumrhu:
Ukuze inkqubo ye-IS ihlale iqinisekisiwe, zonke izinto ezintathu kufuneka zibe neeparameters zombane ezihambelanayo:
- Isiphumo sesithintelo:I-Voc (V), Isc (A),Oko(ubuninzi obuvumelekileyo bomthamo),I(ubuninzi obuvunyelweyo bokungenisa)
- Inyani yeCable: Cc(umthamo wekhebula/km),I-Lc(ukungena kwentambo/km)
- Isixhobo somculo:I-Ci (i-capacitance yangaphakathi), i-Li (i-inductance yangaphakathi)
Ifomula yoQinisekiso:
- Ukujonga ubungakanani bomthamo:(Cc × Ubude) + Ci ≤ Ca
- Ukuhlolwa kokungeniswa:(Lc × Ubude) + Li ≤ La
Isiphumo Esibalulekileyo:Ukuba umenzi wekhebula akaboneleliAmaxabiso e-Cc kunye ne-Lc, intambo ayinakusetyenziswa kwinkqubo ye-IS eqinisekisiweyo. Yiyo loo nto ukusebenzisa "nayiphi na intambo ekhuselweyo" kwindawo enobungozi kuyingozi kwaye akuthobeli imithetho.
KwiDingzun Cable,sibonelelaiiparameter ze-Lc (µH/m) kunye ne-Cc (nF/km) eziqinisekisiweyongokuthunyelwa kwekhebula le-IS ngakunye—okukuvumela ukuba wenze izibalo ezichanekileyo zequmrhu kwaye ugcine ukuthobela imithetho yendawo enobungozi.
- I-Ex-ia vs. I-Ex-ib vs. I-Ex-ic: Amanqanaba oKhuselo lwe-IS
Iisekethe ze-IS zihlulwe ngokwendlela ezinyamezela ngayo iimpazamo kunye nendawo enobungozi evumelekileyo.

Ngoba Intambo yeDingzun Ukufakela Indawo Yakho Enobungozi:
- Ukwenziwa ngokwezifiso okukhulu— Inani labaqhubi (1 ukuya kwi-100+), igeyiji, ukuxinana, uxinano lokukhusela, izinto zeshelufu—zonke zilungiselelwe usetyenziso lwakho lwe-IS
- Yenzelwe ukhuseleko— Ulwakhiwo oluphantsi lwe-Cc/Lc oluneeparamitha zezinto ezibhaliweyo zokuhambelana kwezithintelo
- Iqela leengcali zobunjineli— Inkxaso yokubalwa kweeparameter zequmrhu (ukufaniswa kweCa/La) ukuqinisekisa ukuqinisekiswa kwenkqubo ye-IS
- Unxibelelwano oluthe ngqo lobuchwephesha— Iikowuteshini ezikhawulezayo, amaphepha edatha apheleleyo obuchwephesha anexabiso eliqinisekisiweyo le-Cc/Lc, kunye nokuthunyelwa kwehlabathi
- Amaxwebhu apheleleyo— Iingxelo zovavanyo, izatifikethi zokuthobela imithetho, izibhengezo zeRoHS/REACH, kunye nokulandeleka kwayo yonke impahla ethunyelweyo
Ngaba ufuna intambo ekhuselekileyo eqinisekisiweyo yezixhobo zakho ezinobungozi?
