Inqubo Yokwenziwa Kwekhebula Yezinhlelo Zokulawula Izimboni
Ezweni lezimboni zanamuhla, izinhlelo zokulawula ziwumthombo wokuphila ogcina izinqubo zokukhiqiza zizinzile, ziphephile, futhi zisebenza kahle. Ngemuva kwamaphaneli okulawula, ama-PLC, izinzwa, ama-actuator, kanye namanethiwekhi okuxhumana ezimboni kunendawo evame ukubonakala ilula kodwa ibalulekile: izintambo. Izintambo zezinhlelo zokulawula zezimboni azizona nje iziqhubi zikagesi, kodwa futhi ziyimidiya yokudlulisa isignali edinga ukuthembeka okuphezulu ngokumelene nokuphazamiseka kwe-electromagnetic, ukudlidliza, amazinga okushisa aphezulu, amakhemikhali, kanye nezimo zemvelo ezinzima. Ngakho-ke, inqubo yokwenziwa kwezintambo kumele yenziwe ngendlela ehlelekile, ngokulinganisa, futhi ilandele amazinga ekhwalithi aqinile.
1. Ukuhlela Nokunquma Imininingwane
Izigaba zokuqala zokwenziwa kwekhebula ziqala isikhathi eside ngaphambi kokuba kwenziwe noma yikuphi ukusika noma ukugoqa. Ithimba lobunjiniyela livame ukuhlanganisa izidingo ngokusekelwe kuma-schematics (ama-wiring diagrams), ama-instrument loop diagrams, ama-single-line diagrams, kanye nohlu lwe-I/O. Kula madokhumenti, kunqunywa uhlobo lwekhebula olufanele: ikhebula lokulawula elinomgogodla omningi, ikhebula lezinsimbi ezivikelwe, ikhebula lamandla lama-actuator, noma izintambo zokuxhumana ezifana ne-RS-485, i-industrial Ethernet, noma i-Profibus.
Imininingwane ekhethiwe ifaka inani lama-core, indawo ye-conductor cross-sectional, uhlobo lwe-conductor (ithusi eligoqekile/eliguquguqukayo noma eliqinile), izinto zokushisa (i-PVC, i-XLPE, i-PE), izinto zejakethi yangaphandle (i-PVC, i-PUR, i-LSZH), isilinganiso se-voltage, ukumelana nokushisa, kanye nezidingo zokuvikela (i-foil, elukiwe, noma inhlanganisela). Ngaphezu kwalokho, amazinga asetshenziswa endaweni, njenge-IEC, i-UL, noma amazinga angaphakathi efektri, kudingeka acatshangelwe.
2. Ukukhethwa Kwezinto Ezisetshenziswayo Nezingxenye Ezisekelayo
Uma imininingwane isivunyelwene ngayo, inqubo iyaqhubeka nokuthengwa kwezinto. Izinto eziyinhloko yikhebula uqobo, kodwa ukwenziwa kwalo kuhilela nezinye izingxenye ezifana nama-terminal lugs, ama-ferrules, ama-heat shrink, ama-marker noma amalebula, ama-cable glands, i-conduit noma i-flexible hose, izibopho zekhebula, kanye nokuvikelwa okwengeziwe njengokugoqa okujikelezayo noma imikhono elukiwe.
Ukukhethwa kwezingxenye ezisekelayo kufanele kuqashelwe. Isibonelo, ukusebenzisa i-ferrule esezingeni eliphezulu yezintambo ezivalelekile kungathuthukisa ikhwalithi yokuxhuma kumabhulokhi e-terminal futhi kuvimbele imicu ukuthi ingasabalali ngesikhathi sokuqina. Ezindaweni ezinokudlidliza okuphezulu, ukukhetha indlela ye-lug kanye ne-terminal locking kuyisici sokuthembeka. Ezindaweni ezinengozi yomlilo, izinto ezingenantuthu eningi, i-zero-halogen (LSZH) zivame ukudingeka.
3. Ukulinganisa Ubude kanye Nekhebula Lokusika
Isinyathelo esilandelayo ukusika ikhebula libe nobude obudingekayo. Ikhebula akufanele libe lifushane kakhulu, njengoba lisengozini yokucindezelwa ngesikhathi sokufakwa futhi lithambekele ekuqhekekeni. Kodwa-ke, akufanele libe lide kakhulu, njengoba lizokwenza iphaneli libukeke lingahlelekile, kube nzima ukuxazulula izinkinga, futhi kwandiswe izindleko.
Empeleni, ukubala ubude kubheka indlela ikhebula elihamba ngayo, irediyasi encane yokugoba, ukuhlanzeka kokuphathwa kwekhebula ngaphakathi kwephaneli, kanye nendawo yokuphela kuzo zombili izinhlangothi. Inqubo yokusika ngokuvamile isebenzisa ithuluzi elikhethekile lokusika ukuqinisekisa ukusika okubushelelezi ngaphandle kokulimaza ukuvikela okuyinhloko.
4. Ukukhumula ijakhethi yangaphandle kanye nokufakwa kokuvikela okuyinhloko
Ngemva kokuba ikhebula lisikiwe, ijakhethi yangaphandle iyasuswa. Lesi sinyathelo sidinga ukunemba ukuze kugwenywe ukulimaza isivikelo noma ukuvikela okuyinhloko. Ngezintambo zezinsimbi ezivikelwe, ijakhethi yangaphandle iyasuswa ngokwanele ukuze isivikelo sihlelwe futhi sisekelwe njengoba kuklanyelwe.
Okulandelayo, susa i-insulation kusuka ku-core ngayinye njengoba kudingeka ukuze uqede. Ukususa i-insulation isikhathi eside kakhulu kungaholela ekufinyeleni phakathi kwama-core, kuyilapho ukususa i-insulation isikhathi eside kakhulu kungaholela ekuxhumekeni okubuthakathaka. Abakhiqizi be-terminal noma be-lug ngokuvamile banikeza ubude obunconywayo bokususa i-insulation.
5. Ukuphathwa Kwezintambo Zokuvikela Nokukhipha Amanzi
Ezintanjeni ezivikelwe, ukwenziwa okufanele kuhlanganisa ukuvikela ukuze kuncishiswe umsindo we-electromagnetic ngempumelelo. Ukuvikela kungaba yi-aluminium foil, ithusi elilukiwe, noma kokubili. Intambo yokukhipha amanzi ivame ukufakwa ukuze kube lula ukuxhumanisa phansi.
Yilapho-ke kubalulekile ukulandela ifilosofi eyamukelekayo yokusekela: ukufaka isisekelo sephuzu elilodwa ukuze kuncishiswe izihibe zomhlabathi ezimpawini ezithile ze-analog, noma ukufaka isisekelo sephuzu eliphindwe kabili kwezinhlelo zokusebenza ezithile zokuxhumana, njengoba kunconywe ngumthengisi. Iphutha elivamile lokukhiqiza ukusika isivikelo sibe sifushane kakhulu noma ukusivumela ukuthi sithinte ezinye izingxenye eziqhuba ugesi, okubangela ukuphazamiseka.
6. Ukubopha, Ukufakwa kwe-Ferrule, kanye Nokuqedwa
Ukugoqa kuyisisekelo senqubo yokwenza ikhebula lokulawula. Le ndlela idala ukuxhumana okuqinile kwemishini kanye nogesi phakathi komqhubi kanye ne-terminal (i-lug/ferrule). Ikhwalithi ye-crimp ithonywa izici eziningana: uhlobo lwe-lug olufanele, usayizi we-cross-sectional wekhebula ofanele, ithuluzi le-crimp elilinganisiwe, kanye nendlela efanele ye-crimping.
Kumabhulokhi okugcina amaphaneli, ama-ferrule avame ukusetshenziswa ukugcina iziphetho zezintambo ezivalelekile zicocekile futhi kulula ukuziqinisa. Ukuze kuxhunywe kumadivayisi athile asensimini noma ama-busbars, kusetshenziswa amasongo noma amafoloko njengoba kudingeka. Ngemva kokugoqa, kuvame ukwenziwa ukuhlola okubonakalayo ukuqinisekisa ukuthi i-crimp iyalingana, ayinamifantu, ukuxega, futhi ukufudumala akucindezelwa ngokweqile.
7. Ukulebula Ikhebula Nokuhlonza
Izinhlelo zokulawula zezimboni zithembele ekuhlonzeni okucacile. Ngakho-ke, ikhebula ngalinye kanye ne-core yekhebula kumele kufakwe ilebula ngokwenombolo yethegi, inombolo yesiphelo, noma ikhodi eboniswe emdwebweni. Izindlela zokulebula zingafaka phakathi izimpawu zekhebula ezishelelayo, ukushintshwa kokushisa okuphrintiwe, noma amalebula afakwe i-laminated.
Ukufakwa kwesivinini sokulebula okuqhubekayo, kwenza kube lula ukuqalisa ukusebenza, kunciphisa amaphutha ezintambo, futhi kusheshise ukuxazulula izinkinga lapho kuvela izinkinga. Ukuqamba izindinganiso kuvame ukulandela imithetho yephrojekthi, njengezinombolo zamaphaneli, izinombolo ze-I/O, kanye nezinombolo ze-instrument loop.
8. Ukuhlanganiswa Kwezintambo kanye Nokuphathwa Kwezintambo
Kumaphaneli amaningi okulawula, izintambo zenziwa ngama-harnesses noma ama-bundle. Izintambo ziboshwe kusetshenziswa izintambo noma izintambo, futhi kuvikelwe okwengeziwe uma zidlula emaphethelweni abukhali noma eduze kwezingxenye ezishisayo. Ukuphathwa kwezintambo kuhilela ukuhlukanisa izintambo zesiginali kanye nogesi ukuze kuncishiswe ukuphazamiseka: izintambo zesiginali ye-analog kanye nezokuxhumana zivame ukuhlukaniswa nezintambo zikagesi ze-motor noma ze-AC.
Ngaphezu kwalokho, irediyasi encane yokugoba kumele igcinwe ukuze kuvinjelwe ukucindezeleka komshini enkabeni yekhebula. Imikhuba emihle ihlanganisa nokuhlinzeka "ngezihibe zesevisi" ezanele ukuvumela idivayisi ukuthi isuswe ukuze ilungiswe ngaphandle kokunqamula ikhebula.
9. Ukuhlolwa Kwekhwalithi Yokuqhubeka, Ukufakwa Kokushisa, kanye Nokuxhumeka
Ngaphambi kokuba izintambo zisuswe ukuze zifakwe noma ngaphambi kokuba amaphaneli athunyelwe, kwenziwa ukuhlolwa. Ukuhlolwa okuyisisekelo ukuhlolwa kokuqhubeka ukuqinisekisa ukuthi umongo ngamunye uxhunywe kahle kusukela ekugcineni kuya ekugcineni. Ngemva kwalokho, kwenziwa ukuhlolwa kokumelana nokufakwa komoya (megger), ikakhulukazi ezintanjeni ezithile, ukuqinisekisa ukuthi akukho ukuvuza kokufakwa komoya.
Kumakhebula noma amakhebula okuxhumana anezidingo ezikhethekile, kungase kwenziwe ukuhlolwa okwengeziwe, njengokuqinisekiswa kwe-pinout, ukulinganiswa kwe-impedance, noma ukuhlolwa kokuxhumeka kokuvikela. Ezinye izikhungo zenza nokuhlolwa kokudonsa kumakhebula aqhekekile ukuqinisekisa ukuthi amandla omshini ahlangabezana nezidingo.
10. Imibhalo kanye nokulawulwa kwekhwalithi
Ukwenziwa kahle kwekhebula kuhlale kuhlanganisa imibhalo: ishejuli yekhebula, imibiko yokuhlola, izingodo zokushintsha (imigqa ebomvu), kanye nezithombe noma amarekhodi okukhiqiza, uma kudingeka. Emaphrojekthini ezimboni, ikhebula ngalinye livame ukuba nobunikazi obuhlukile, obulandelekayo. Le mibhalo ibalulekile ekuhlolweni, ekugcinweni nasekukhulisweni kwesistimu esikhathini esizayo.
Ukulawulwa kwekhwalithi kuhlanganisa ukuhlolwa kwezinto ezingenayo, ukuhlolwa kwangaphakathi kwenqubo, kanye nokuhlolwa kokugcina. Lokhu kuqinisekisa ukuthi amaphutha angatholakala ngokushesha futhi avinjelwe ukuthi angadluliselwa esigabeni sokusebenza esibiza kakhulu.
I-Penutup
Inqubo yokwenziwa kwekhebula kwezinhlelo zokulawula izimboni akuyona into elula engenziwa ngaphandle kwezindinganiso nezinqubo. Ihilela uchungechunge lwezinyathelo, kusukela ekuhleleni imininingwane kanye nokukhethwa kwezinto, ukusika, ukukhumula, ukuphathwa kokuvikela, ukugoqa, ukulebula, ukuhlanganiswa kwe-harness, ukuhlolwa, kanye nemibhalo yekhwalithi. Isinyathelo ngasinye sithinta ukuthembeka kohlelo lokulawula lonke. Ngokwenziwa okuhlelekile nokuvivinyiwe, ingozi yokungasebenzi, ukuphazamiseka komsindo, amaphutha ezintambo, kanye nokwehluleka kokuxhumeka kungancishiswa—ukusekela imisebenzi yezimboni ephephile, ezinzile, nephumelelayo.
