Waa maxay macnaha fiilada gudaha ee badbaadada leh?
- Hordhac: Maxay Muhiim u tahay "Amni ahaan Gudaha"
Warshadaha sida warshadaha sifeynta saliidda, warshadaha kiimikada, xarumaha farsamaynta gaaska, macdanaha dhuxusha dhulka hoostiisa mara, iyo wax soo saarka dawooyinka, hawadu waxay ka kooban tahay gaasas guban kara, uumi, ama boodh guban kara. Meelahan khatarta ah, dhimbiil koronto oo fudud oo ka yimaada fiilo burburtay ama xidhiidh dabacsan ayaa kicin kara qarax masiibo ah.
(Jaantuska nidaamka gudaha ee Badbaado (IS))
Halkan waa meeshafiilooyin ammaan ah oo gudaha ah (IS)noqo mid muhiim u ah howlgalka.
Fiilo gudaha ah oo ammaan ah ayaa loo sameeyay si looaan dhalin ama kaydin tamar koronto oo ku filansi loo kiciyo dabka—xitaa xaaladaha cilladaha sida wareegyada gaagaaban ama cilladaha dhulka. Si ka duwan hababka aan qarxin (Ex-d) ee ka kooban qarax gudaha meel culus ku yaal, badbaadada gudaha ayaa ka hortagta in qaraxu marka hore dhaco.
Tilmaamahan wuxuu sharxayaa macnaha fiilada gudaha ku jirta ee ammaan ah, sida ay u shaqeyso, doorka muhiimka ah ee awoodda iyo inductance, iyo sababta lambarka midabka buluugga ah loogu baahan yahay adduunka oo dhan rakibidda meelaha khatarta ah.
- Qeexitaan: Waa maxay Fiilada Gudaha ee Ammaan ah?
Qeexitaan Rasmi ah:Wareeg gudaha ah oo ammaan ah waa mid "kaas oo wax kasta oo dhimbiil ama saameyn kuleyl ah aysan awoodin inay keento dab-shid isku-darka walxo guban kara ama guban kara hawada iyadoo la raacayo xaaladaha tijaabada ee loo qoondeeyay" (IEC 60079-11).
Iyadoo loo adeegsanayo fiilooyinka, Eland Cables waxay bixisaa sharraxaad wax ku ool ah:
"Fiilooyinka korontada asal ahaan waa la shaabadeeyay sidaas darteed waxaa loo arki karaa inay yihiin kuwo ammaan ah oo gudaha ah codsiyada qaarkood haddii laga ilaaliyo waxyeelada, goobaha korontada ee dibadda ama birlabta (EMI), oo laga go'doomiyo wareegyada aan amniga ahayn ee gudaha."
Marka si fudud loo dhigo:Fiilo gudaha ah oo ammaan ah, marka loo isticmaalo qayb ka mid ah nidaamka IS ee shahaadaysan oo leh caqabado ku habboon oo xaddidaya tamarta, waligiis ma soo saari doono dhimbiil kulul oo ku filan ama awood leh oo ku filan inuu shido jawiga khatarta ah ee ku xeeran.
Kala duwanaanshaha Muhiimka ah:
| Habka Ilaalinta | Sida ay u Shaqeyso | Doorka Fiilada |
| Qarxinta-Cabitaanka (Dib-u-dhac) | Waxay ka kooban tahay qaraxa gudaha xero culus oo olol leh | Fiilada ayaa soo gasha iyada oo loo marayo qanjirka ololka ka hortaga; qolofku wuxuu qabtaa shaqada ilaalinta |
| Badbaadada Gudaha (Ex-i / IS) | Waxay ka hortagtaa dab-shidkaiyadoo la xaddidayo tamarta korontada ee ka hooseysa heerarka dab-shidka | Xuduudaha korantada ee fiilada (capacitance, inductance) waa in la xakameeyaa; gaashaanku waa inuu ka hortagaa kicinta EMI. |
Dingzun Cable,Fiilooyinka qalabkayaga ee gudaha ku jira ee badbaadada leh waxaa lagu farsameeyay qaab-dhismeed awood yar, qaab-dhismeed soo-jiidasho yar iyo jaakad buluug khafiif ah oo IEC 60079-14 ah - taasoo hubinaysa in qalabkaaga aagga khatarta ah uu ahaado mid ammaan ah oo la xaqiijiyay.
- Sida ay u Shaqeyso: Mabda'a Xaddidaadda Tamarta
Nidaam gudaha ah oo ammaan ah kuma tiirsana meelo culus oo lagu xiro. Taa beddelkeeda, wuxuu ku tiirsan yahayxaddidaadda tamarta.
3.1 Qaab-dhismeedka Nidaamka IS
Wareegga qalabka IS ee caadiga ah wuxuu ka kooban yahay saddex qaybood oo wada shaqeynaya:
| Qaybta | Goobta | Shaqada |
| Caqabadda IS(Zener Diode ama Galvanic Isolator) | Aag Ammaan ah (Qolka Xakamaynta) | Waxay ku xaddidaysaa danabka, hadda, iyo awoodda guud heerar ammaan ah (badanaaka hooseeya 1.3 watts, badanaa |
| Fiilada IS | Aagga Khatarta leh (Aagga 0/1/2) | Gudbisaa tamarta xaddidan inta ay socotoaan la kaydin tamar dheeraad ahtaas oo loo sii deyn karo sidii dhimbiil |
| Qalabka Goobta IS | Aagga Khatarta leh (tusaale ahaan, Aagga 1) | Loogu talagalay inay si ammaan ah ugu shaqeyso baqshadda tamarta xaddidan |
3.2 Dhibaatada Kaydinta Tamarta: Sababta Awoodda iyo Inductance-ku Muhiim u yihiin
Xitaa iyadoo leh caqabad qumman oo xaddidaysa awoodda fiilada lafteedawaxay ku kaydin kartaa tamarta korontada laba qaab:
Awoodda (C):Fiilada waxay u shaqeysaa sida kapastor. Kondur kasta, iyo booska u dhexeeya kondur iyo gaashaanka, waxay kaydisaa dallacaadda korontada. Marka fiilada la gooyo ama la gaabiyo, dallacaadda la keydiyay waxay u soo baxaysaa sidii dhimbiil.Awoodda sare = dhimbiil weyn = khatar dab-shid oo sareysa.
Soo-qaadista (L):Wareegga fiilada ayaa kaydiya tamarta birlabta. Marka wareegga la furo, goobta birlabta ee la keydiyay ayaa burburta, taasoo soo saarta koror danab ah oo abuuri kara dhimbiil.Inductance sare = koror weyn oo danab ah = khatar dab-shid oo sareysa.
Shaxda 1: Sababta Awoodda Yar iyo Soo-jiidashada Yar ay Muhiim ugu yihiin Fiilooyinka IS
| Halbeegga | Astaan | Cutubyo | Khatarta | Shuruudaha IS |
| Awoodda (Xuduudaha-Dhexe) | Cc | nF/km ama pF/m | Fiilada waxay kaydisaa dallacaadda korontada. Marka la gaabiyo, dallacaaddu waxay u daadataa sidii dhimbiil. Cc Sare = dhimbiil weyn | Waa inay hooseysaa( |
| Awoodda (Gaashaanka Aasaasiga ah) | Cc | nF/km ama pF/m | Bakhaarku wuxuu ku dallacaa inta u dhaxaysa koontaroolaha iyo gaashaanka. Muhiim u ah fiilooyinka la shaabadeeyey. | Waa in la diiwaan geliyaa |
| Inductance | Lc | µH/m ama mH/km | Wareegga fiilada ayaa kaydiya tamarta birlabta. Marka la furo, goobta burburaysa waxay abuurtaa koror danab ah | Waa inuu ahaadaa mid hooseeya oo la xakameeyey |
| Saamiga L/R | L/R | µH/Ω | Joogtada waqtiga ee wareegga; loo isticmaalo shahaadada fiilooyinka macdanta (BS 6704) | Waa inay waafaqsan tahay qeexitaannada xayndaabka |
Saamaynta Wax-ku-oolka ah:Fiilada caadiga ah ee awoodda sare leh (tusaale ahaan, fiilada PVC-dahaarka leh ee raqiiska ah) waxay kaydisaa tamar ka badan fiilada IS-dahaarka leh ee awoodda hoose leh (dahaarka PE ama XLPE). Isticmaalka fiilada aan shahaadada lahayn oo leh caqabad IS oo shahaado haysta waxay gebi ahaanba jebin kartaa nidaamka badbaadada - sababtoo ah fiilada lafteedu waxay noqotaa il dab-shid ah.
Dingzun Cable,isticmaalka fiilooyinka qalabka IS-gaDahaarka PE (Polyethylene) ama XLPEoo leh joogto dielectric hooseeya (ε)khaanadaha= 2.3), taasoo keenaysa awoodda koontaroolka-ilaa-koontaroolka ee≤150 nF/km— hubinta heerarka kaydinta tamarta ee badbaadada leh ee rakibidda meelaha khatarta ah.
- Koodhka Midabka Buluugga ah: Maxay Fiilooyinku Buluug u yihiin?
Caalam ahaan, fiilooyinka loo isticmaalo wareegyada gudaha ee amniga ah waxaa lagu aqoonsadaagalka dibadda ee buluugga ah(badanaa buluug khafiif ah, RAL 5015).
(fiilooyin ammaan ah oo gudaha ah (IS) rakibaadda)
Shaxda 2: Shuruudaha Koodhka Midabka Buluugga ah (IEC 60079-14)
| Shuruudaha | Faahfaahinta | Sababta ay Muhiim u tahay |
| Midabka Galka | Buluug Fudud (RAL 5015) | Aqoonsi muuqaal ah oo degdeg ah inta lagu jiro rakibidda iyo dayactirka |
| Calaamadaynta | Calaamadayn waarta: "Ex-ia" ama "Ex-ib" | Waxay xaqiijineysaa qiimeynta Badbaadada Gudaha ee fiilada |
| Saldhigyada | terminaalada buluug khafiif ah ama gacmo-gashi | Waxay ka hortagtaa isku xirka shilalka ah ee wareegyada korontada ee aan ahayn IS |
| Nidaamyada Biyomareenka | Haddii la isticmaalo, marinku waa inuu ahaadaa mid buluug khafiif ah ama calaamadaysan | Kala soocida wareegyada aan ahayn IS |
Sababta Cod-bixinta Midabka ay Muhiim u tahay:
Koronto yaqaannada iyo shaqaalaha dayactirka ee ka shaqeeya meelaha khatarta ah waa inay si degdeg ah u kala saaraan wareegyada IS (tamarta badbaadada leh) iyo wareegyada korontada ee aan ahayn IS (tamarta khatarta ah). Haddii farsamo yaqaanku si kama' ah ugu xiro fiilada korontada ee aan ahayn IS (tusaale ahaan, 120V AC) baloogga terminalka IS, tamarta ka dhalata waxay ka badnaan kartaa heerka badbaadada ee caqabadda - taasoo nidaamka "ammaan" ee la xaqiijiyay u rogi karta khatar qarax ah.
Fiiro Gaar ah oo ku saabsan U hoggaansanaanta:Haddii qolofta fiiladaadu ay tahay madow, cawl, ama midab kasta oo aan ahayn buluug khafiif ah, waa inay noqotaamayau hoggaansan wareegyada IS sida waafaqsan IEC 60079-14—iyadoon loo eegin waxqabadkeeda korontada.
Dingzun Cable,Fiilooyinkayaga gudaha ee ammaanku waxay leeyihiinjaakad dibadda ah oo buluug khafiif ah (RAL 5015) ahleh calaamadda Ex-ia/Ex-ib oo waarta - hubinta u hoggaansanaanta aagga khatarta ah ee degdegga ah.
- Fikradda Hay'adda: Sababta ay tahay in loo xaqiijiyo cabbirrada fiilooyinka
Si nidaamka IS uu u sii ahaado mid shahaado haysta,dhammaan saddexda qaybood—xaynka, fiilada, iyo qalabka goobta—waa inay lahaadaan xuduudo koronto oo iswaafaqsan. Tan waxaa loo yaqaannaaFikradda Hay'adda.
Shaxda 3: Halbeegyada Hay'adaha ee Xaqiijinta Nidaamka IS
| Qaybta | Halbeegyada Muhiimka ah | Sharaxaad |
| Caqabad (Aagga Badbaadada ah) | Codka (V), Iskoorka (A),Ca (Mugga ugu badan ee la oggol yahay),La (Inductance-ka ugu badan ee la oggol yahay) | Waxay qeexaysaa inta tamar ee fiilada ay caqabaddu si ammaan ah u dulqaadan karto |
| Fiilada IS | Cc (Awoodda fiilada/km),Lc (Fiilada soo-gelinta/km) | Waa in lagu diiwaan geliyaa xaashida xogta fiilada |
| Qalabka Goobta | Ci (Awoodda Gudaha), Li (Internal inductance) | Waxaa bixiyay soo saaraha qalabka |
Qaacidada Xaqiijinta:
- Hubinta Awoodda:(Cc × Dhererka Fiilada) + Ci ≤ Ca
- Hubinta Inductance-ka:(Lc × Dhererka Fiilada) + Li ≤ La
Saamaynta Muhiimka ah:Haddii soo saaraha fiilada uusan bixinCc(awoodda) iyoLc(qiimaha inductance), fiilada looma isticmaali karo nidaamka IS ee la xaqiijiyay. Tani waa sababta isticmaalka "fiilooyin kasta oo gaashaan leh" meel khatar ah ay khatar u tahay oo aan waafaqsanayn - ma xaqiijin kartid xuduudaha hay'adda iyada oo aan la haysan xogta.
Dingzun Cable,waan bixinaaXuduudaha Lc ee shahaadaysan (µH/m) iyo Cc (nF/km)iyada oo la adeegsanayo shixnad kasta oo fiilada IS ah — taasoo kuu suurtagelinaysa inaad sameyso xisaabinta saxda ah ee hay'adaha iyo inaad ilaaliso u hoggaansanaanta aagga khatarta ah.
- Ex-ia vs. Ex-ib: Heerarka Badbaadada Gudaha
Wareegyada IS waxaa si dheeraad ah loogu kala saaraa dulqaadka cilladahooda iyo aagga khatarta ah ee la oggol yahay.
Shaxda 4: Qiimaynta Ex-ia iyo Ex-ib ee fiilooyinka
| Qiimaynta | Dulqaadka Khaladka | Aagga Khuseeya | Shuruudaha Fiilada |
| Laga bilaabo hadda | Laba cilladood oo madax-bannaan | Aagga 0(Khatarta qaraxyada joogtada ah) | Baahiyahaugu adagXadka L/C; hufnaanta amniga ugu sarreysa |
| Kii hore | Hal cillad oo keliya | Aagga 1aad(Khatarta qaraxda ee u badan tahay) | Baahiyahadhexdhexaad ahXadka L/C; fiilada IS ee caadiga ah waa ku filan tahay |
| Hore-ic | Cilad ma jirto (hawlgalka caadiga ah oo keliya) | Aagga 2aad(Ma dhici karto, muddo gaaban) | Ma jiraan xad gaar ah oo L/C ah; fiilada caadiga ah ayaa laga yaabaa in la aqbalo |
Saamaynta Xulashada Fiilada:Wareegyada Ex-ia waxay u baahan yihiin xitaa xadka awoodda iyo inductance-ka oo ka hooseeya Ex-ib si loo hubiyo badbaadada xaaladaha laba-cilad. Had iyo jeer hubi heerka IS ee loo baahan yahay ka hor intaadan cayimin fiilada.
- Shuruudaha Difaaca ee Fiilooyinka IS
Sida ku cad Qaybta NFPA 70 504.30,gaashaan ayaa loo baahan yahaywareegyada gudaha ee amniga ah si looga hortago isku xirka EMI.
Sababta Gaashaandhiggu Muhiim u yahay:Darawalada Soo Noqnoqoshada Kala Duwan (VFDs), gudbiyaasha raadiyaha, iyo qalabka alxanka ayaa dhaliya faragelinta elektromagnetic-ka (EMI). EMI-gan wuxuu awood u leeyahay inuu soo saaro koronto-dhaliye (EMI).kiciyo danab iyo haddaFiilada qalabka oo dheer socota—xitaa haddii caqabaddu ay korontada ku xaddidayso 1.2W, ilo EMI oo dibadda ah ayaa kicin kara tamar ku filan si loo abuuro dab-shid awood u leh inuu kiciyo.
(fiilada aluminiumka ah ee la shaabadeeyey iyo tidcan silig naxaas ah oo qasacadaysan)
Shaxda 5: Ikhtiyaarada gaashaanka ee fiilooyinka IS
| Nooca Gaashaanka | Daboolida | Codsiga ugu Fiican | Ku habboonaanta IS |
| Gaashaanka Foornada | 100% | Rakibaadaha go'an, EMI-ga soo noqnoqda sare leh | La aqbali karo orod gaaban oo aan joogto ahayn |
| Gaashaanka Braid | 70-95% | Codsiyada firfircoon/dabacsan, EMI-ga soo noqnoqda ee hooseeya | Waxaa lagu taliyay macdan qodista, robotics-ka |
| Isku-dhafan (Fayil + Tidcan) | 100% + timo tidcan | Warshadeed adag, EMI sare | Ku habboon warshadaha sifeynta, warshadaha kiimikada |
Xeerka Saldhigga:Gaashaanka waa in lagu saleeyaa dhulkahal dhibic oo keliya(badanaa aagga nabdoon ee ku yaal xayndaabka) si looga hortago wareegyada dhulka ee keeni kara tamar khatar ah.
Dingzun Cable,Astaamaheena fiilooyinka qalabka ISgaashaanka tidcan ee naxaasta ah ee qasacadaysan (ka badan 85% daboolida)sida caadiga ah—xannibaadda kicinta EMI iyadoo la ilaalinayo u hoggaansanaanta IS.
- Tilmaamaha Farsamo ee Muhiimka ah ee Fiilooyinka IS
Markaad qeexayso fiilooyinka gudaha ee badbaadada leh ee meelaha khatarta ah, xaqiiji xuduudahan muhiimka ah:
Shaxda 6: Liiska Hubinta Tilmaamaha Fiilada IS
| Halbeegga | Shuruudaha IS | Sababta ay Muhiim u tahay |
| Awoodda (Xuduudaha-Dhexe) | ≤150 nF/km(Dahaadhka PE/XLPE) | Xaddidaadda kharashka la keydiyay; waxay hubisaa in hay'addu ay la jaanqaadayso qiimaha Ca ee caqabadda ah |
| Awoodda (Gaashaanka Aasaasiga ah) | ≤250 nF/km | Muhiim u ah fiilooyinka la shaabadeeyay; waxay saameysaa tamarta kaydsan |

| Qiimaynta Ololka | IEC 60332-1-2 ama ka wanaagsan | Badbaadada dabka |
- Khuraafaadka Caadiga ah ee ku saabsan fiilooyinka gudaha ee badbaadada leh
| Khuraafaad | Xaqiiqada |
| "Fiilo kasta oo gaashaan leh waa mid lagu qiimeeyay IS." | Been. Fiilooyinka IS waxay u baahan yihiin cabbirro Cc/Lc oo la xakameeyey iyo dahaadh buluug ah. Fiilooyinka difaaca caadiga ah ma laha cabbirro shahaadaysan. |
| "Caqabaddu waxay qabataa dhammaan shaqada badbaadada—fiilada muhiim ma aha." | Been. Fiilada waxay kaydisaa tamarta (capacitance/inductance). Fiilada capacitance-ka sare leh waxay ka adkaan kartaa qiimeynta badbaadada ee caqabadda. |
| "Fiilada buluugga ah waa midab suuqgeyn oo keliya." | Been. Buluug waxaa IEC 60079-14 ku waajibisay aqoonsiga wareegga IS. Fiilada aan buluugga ahayn waa mid aan waafaqsanayn. |
| "Fiilada IS waa mid aad u badan oo loogu talagalay codsigayga." | Waxay ku xiran tahay. Haddii aad haysato gaas/uumi/boor guban kara oo shaqeynaya si caadi ah, IS (ama Ex-d) waa qasab iyadoo loo eegayo xeerka korontada. |
| "Waxaan ku xidhi karaa fiilada IS isku xidhka caadiga ah." | Been. Kala-goysyadu waxay abuuraan xuduudo koronto oo aan la garanayn (Ci, Li) oo wax u dhimaya xisaabinta hay'adaha. |
