Zonke izixhumi ezinogesi, ezingase zidale umlilo, ngakho isixhumi kufanele simelane nomlilo.Kuphakanyiswa ukuthi ukhethe isixhumi samandla esenziwe ukubambezeleka kwelangabi nezinto zokuzicisha.
Ipharamitha yezemvelo ihlanganisa izinga lokushisa, umswakama, ukushintsha kwezinga lokushisa, ukucindezela komkhathi nokugqwala kwemvelo.Njengoba indawo yezokuthutha neyokugcina inomthelela omkhulu kusixhumi, ukukhethwa kwesixhumi kufanele kusekelwe endaweni yangempela.
Izixhumi zingahlukaniswa zibe izixhumi zefrikhwensi ephezulu kanye nesixhumi sefrikhwensi ephansi ngokusekelwe kufrikhwensi.Ingase futhi ihlukaniswe ngokusekelwe kumumo ibe isixhumi esiyindilinga nesixhumi esingunxande.Ngokusho kokusetshenziswa, izixhumi zingasebenzisa ebhodini eliphrintiwe, ikhabethe lemishini, imishini yomsindo, isixhumi samandla nokunye ukusetshenziswa okukhethekile.
Uxhumano olufakwe ngaphambili luphinde lubizwe ngokuthi i-insulation displacement contact, eyasungulwa ngeminyaka yawo-1960 e-US Inezici ezifana nokuthembeka okuphezulu, izindleko eziphansi, kulula ukuzisebenzisa, njll. Lobu buchwepheshe busetshenziswe kabanzi kusixhumi esibonakalayo sebhodi.Ifanele ukuxhumana kwekhebula le-tape.Asikho isidingo ukususa insulating ungqimba phezu ikhebula, ngoba incike U-emise contact entwasahlobo, okungase ukungena ukuze insulating ungqimba, wenze umqhubi angene inkatho futhi ikhiyiwe in the groove of contact spring, ukuze uqinisekise conduction kagesi. phakathi kwe-conductor ne-leaf spring kuqinile.Uxhumano olufakwe ngaphambili luhlanganisa amathuluzi alula kuphela, kodwa ikhebula elinegeji yocingo elinganiselwe liyadingeka.
Izindlela zifaka i-weld, i-pressure welding, uxhumano lwe-wire-wrap, uxhumano olufakwe ngaphambili, kanye ne-screw fastening.
Izinga lokushisa elisebenzayo lincike ezintweni zensimbi kanye nezinto zokufakelwa kwesixhumi.Izinga lokushisa eliphakeme lingase licekele phansi ukufakwa kwe-insulation, okunciphisa ukumelana nokufakwa kwe-insulation kanye ne-insulation ukumelana ne-voltage yokuhlola;Ukuya ensimbi, izinga lokushisa eliphezulu lingenza indawo othintana nayo ilahlekelwe ukunwebeka, isheshise i-oxidation futhi yenze okokuhlanganisa kuphenduke imetamorphic.Ngokuvamile, izinga lokushisa lemvelo liphakathi kuka -55.
Impilo yobumishini iyisamba sezikhathi zokuxhuma nokukhipha.Ngokuvamile, impilo kaMechanical iphakathi kwezikhathi ezingama-500 kuye kweziyi-1000.Ngaphambi kokufinyelela impilo yemishini, isilinganiso sokumelana nokuxhumana, ukumelana nokufakwa kwe-insulation kanye ne-insulation test voltage akumele kudlule inani elilinganiselwe.
Isixhumi esibonakalayo sebhodi se-ANEN sesixhumi sezimboni samukele isakhiwo esihlanganisiwe, amakhasimende angakwazi ukulandela kalula usayizi wembobo ekucacisweni kwe-trepan nokubopha.
I-Metal Injection Molding (MIM) iyinqubo yokusebenza kwensimbi lapho insimbi enamandla amakhulu ixutshwa nezinto ezihlanganisayo ukuze kwakhiwe "i-feedstock" ebese ibunjwa futhi iqiniswe kusetshenziswa ukubumba komjovo.Ubuchwepheshe obuphezulu obuthuthuke ngokushesha phakathi nale minyaka.
Cha, owesilisa wesixhumi se-IC600 uhlolwe ngaphansi.
Izinto zifaka i-H65 yethusi.Okuqukethwe kwethusi kuphezulu futhi indawo yokugcina imbozwe ngesiliva, okwandisa kakhulu ukuqhutshwa kwesixhumi.
Isixhumi samandla se-ANEN singaxhuma ngokushesha futhi sinqamule.Ingakwazi ukudlulisa ugesi kanye ne-voltage kancane kancane.
Izixhumi zezimboni zifanele isiteshi samandla kagesi, imoto ekhiqiza izimo eziphuthumayo, iyunithi yamandla, igridi yamandla, i-wharf, kanye nezimayini, njll.
Inqubo yokuxhuma: Amamaki akupulaki nesokhethi kufanele akleliswe.Faka ipulaki ngesokhethi esitobhini, bese ufaka ngokuqhubekayo nge-axial pressure futhi ujike kanyekanye uye kwesokudla (okubonwa kupulaki lapho kufakwe khona) kuze kungene ukhiye we-bayonet.
Inqubo yokukhipha ipulaki: Phusha ipulaki uqhubeke futhi ujike kwesokunxele ngesikhathi esifanayo (ngokusekelwe lapho ufaka khona) kuze kube yilapho izimpawu kumapulaki eboniswa ngomugqa oqondile, bese ukhipha ipulaki.
Isinyathelo 1: faka umunwe wokufakazela umunwe ngaphambili komkhiqizo kuze kube yilapho ungakwazi ukuphushwa.
Isinyathelo sesi-2: faka isigxobo esinegethivu se-multimeter ngaphansi komkhiqizo size sifike kutheminali yangaphakathi.
Isinyathelo sesi-3: sebenzisa isigxobo esihle se-multimeter ukuze uthinte ubufakazi bomunwe.
Isinyathelo sesi-4: uma inani lokumelana linguziro, khona-ke ubufakazi beminwe abufikanga kutheminali futhi ukuhlolwa kuphasisiwe.
Ukusebenza kwemvelo kuhlanganisa ukumelana nezinga lokushisa, ukumelana nomswakama, ukudlidliza kanye nomthelela.
Ukumelana nokushisa: izinga lokushisa eliphakeme kakhulu lokusebenza lesixhumi ngu-200.
Amandla okuhlukanisa imbobo eyodwa abhekisela emandleni okuhlukanisa ingxenye yokuxhumana esuka enganyakazi ukuya kweyezimoto, asetshenziselwa ukumela ukuxhumana phakathi kwephinikhodi yokufaka nesokhethi.
Amanye amatheminali asetshenziswa ezindaweni zokudlidliza eziguqukayo.
Lokhu kuhlola kusebenzisa kuphela ukuhlola ukuthi ingabe ukumelana nokuxhumana okumile kufanelekile yini, kodwa akuqinisekisiwe ukuthi kunokwethenjelwa endaweni eguquguqukayo.Ukwehluleka kwamandla ngaso leso sikhathi kungase kuvele ngisho nakuxhumano oluqeqeshiwe ekuhlolweni kwemvelo esilingisayo, ngakho-ke kwezinye izimfuneko zokuthembeka okuphezulu kwamatheminali, kuwukuthi kangcono ukwenza ukuhlolwa kokudlidliza okuguquguqukayo ukuze kuhlolwe ukwethembeka kwayo.
Lapho ukhetha i-wiring terminal, kufanele uhlukanise ngokucophelela:
Okokuqala, bheka ukubukeka, umkhiqizo omuhle ufana nomsebenzi wezandla, onikeza umuntu imizwa ejabulisayo nejabulisayo;
Okwesibili, ukukhethwa kwezinto zokwenziwa kufanele kube kuhle, izingxenye zokufakelwa kufanele zenziwe ngamapulasitiki obunjiniyela abushelelezi ilangabi futhi izinto zokuqhuba akumele zenziwe ngensimbi.Okubaluleke kakhulu ukucutshungulwa kwentambo.Uma ukucutshungulwa kwentambo kungalungile futhi umzuzu we-torsional ungafinyeleli ezingeni, umsebenzi wocingo uzolahleka.
Kunezindlela ezine ezilula zokuhlola : ezibonakalayo (hlola ukubonakala);inani lesisindo (uma lilula kakhulu);usebenzisa umlilo (i-flame retardant); zama i-torsion.
Ukumelana kwe-arc yikhono lokumelana ne-arc yezinto ezivikelayo eduze kwendawo yayo ngaphansi kwezimo zokuhlola ezicacisiwe.Esivivinyweni, isetshenziselwa ukushintshanisa i-voltage ephezulu namanje encane, ngosizo lwe-arc kagesi phakathi kwama-electrode amabili, angalinganisa. ukumelana kwe-arc kwempahla yokufaka, ngokusekelwe esikhathini esibiza ngayo ungqimba lwe-conductive ebusweni be.
Ukumelana okuvuthayo yikhono lokumelana nokushiswa kwe-insulating material lapho ihlangene nelangabi.Ngokusetshenziswa okwandayo kwezinto zokuvikela ukushisa, kubaluleke kakhulu ukuthuthukisa ukumelana nokuvutha kwe-insulator nokuthuthukisa ukumelana kwezinto zokuvikela ngokusebenzisa ezihlukahlukene. kusho.Ukuphakama kokumelana nomlilo, kuba ngcono ukuphepha.
Ingcindezi yokuqina ephezulu ethwalwa yisampula ekuhlolweni kwe-tensile.
Kuyisivivinyo esisetshenziswa kakhulu nesimele ekuhlolweni kwezakhiwo zemishini yezinto zokuvikela.
Uma izinga lokushisa lezinto zikagesi lingaphezulu kwezinga lokushisa legumbi, okudlulele kubizwa ngokuthi ukunyuka kwezinga lokushisa.Uma amandla avuliwe, izinga lokushisa le-conductor lizokhuphuka lize lizinze.Isimo sokuzinza sidinga umehluko wezinga lokushisa ungadluli ku-2.
Ukumelana ne-insulation, ukumelana nokucindezela, ukuvutha.
Ukuhlolwa kwengcindezi yebhola ukumelana nokushisa.Izakhiwo zokubekezelela i-thermoduric zisho izinto zokwakha, ikakhulukazi i-thermoplastic inezindawo zokushaqeka okulwa nokushisa kanye ne-anti-deformation ngaphansi kwesimo esishisayo.Ukumelana nokushisa kwezinto ngokuvamile kuqinisekiswa ukuhlolwa kwengcindezi yebhola.Lokhu kuhlola kusebenza ezintweni zokuvikela ezisetshenziselwa ukuvikela umzimba ofakwe ugesi.
