Isilinganiso Sokucindezela Esifanele Sokugoba Kwesiphetho Esiphezulu | Umhlahlandlela Ogcwele

Ezimweni zamandla aphezulu njengamandla amasha, ubunjiniyela bamandla kanye nokulawulwa kwezimboni, ukugoqa i-terminal crimping kuyinqubo eyinhloko yokuqinisekisa ukuxhumana kukagesi okuphephile. Izibalo zibonisa ukuthi ama-35% emililo kagesi ibangelwa ukuxhumana kwe-terminal okuxekethile noma okubi. Njengepharamitha ebalulekile yenqubo yokugoqa, isilinganiso sokucindezela sinquma ngqo amandla omshini kanye nokuqhuba kukagesi kokuxhumana. Lesi sihloko sichaza ububanzi besilinganiso sokucindezela esifanele, ifomula yokubala, izici ezithonya kanye nezinto ezibalulekile zokusebenza ezisebenzayo zokugoqa i-terminal crimping yamandla aphezulu, okungasetshenziswa ngokushesha.

I. Kuyini i-Compression Ratio? Qonda incazelo yayo eyinhloko kuqala

Isilinganiso sokucindezela (esaziwa nangokuthi izinga lokucindezela noma izinga lokuminyana) silinganisa isilinganiso sokushintsha kwendawo enqamula umqhubi ngaphambi nangemva kokugoqa, okubonisa ukuqina kokulingana phakathi kwabaqhubi nama-terminal. Kunezindlela ezimbili zokubala ezijwayelekile embonini.

I-USCAR-21 (Ivame ukusetshenziswa ezinkundleni zezimoto kanye namandla, izinga lokucindezelwa)

Isilinganiso Sokucindezela (%) = 100×(1 - Indawo enqamulayo yomqhubi ngemva kokugoqa / Indawo enqamulayo yomqhubi oqokiwe ngaphambi kokugoqa)

Isibonelo: Umqhubi ongu-50mm² ngaphambi kokugoqa indawo yakhe enqamulayo yehliswe ngo-20% ngemva kokugoqa, ngesilinganiso sokucindezela esingu-20%.

I-VW 60330 (Isetshenziswa kabanzi ezindinganisweni zaseJalimane nasemasimini ezimboni, isilinganiso sokuqiniswa)

Isilinganiso Sokucindezela (%) = Indawo enqamulayo yomqhubi ngemva kokugoqa / Indawo enqamulayo yomqhubi oqokiwe ngaphambi kokugoqa × 100%

Isibonelo: Uma indawo yomqhubi we-post-crimp ingama-80% endawo yokuqala, isilinganiso sokucindezela singama-80%.

 

II. Isilinganiso Esifanele Sokucindezela Sokugoba Kwesiphetho Esiphezulu

Izidingo eziyinhloko zezinhlelo zokusebenza zamandla aphezulu (ama-conductor ethusi, 6–400mm²): ukumelana okuphansi kokuthintana, amandla aphezulu okudonsa, ukumelana okuhle kakhulu kwezinga lokushisa kanye nokumelana nokudlidliza. Ububanzi obufanele buyahlukahluka ngokwezinto ezibonakalayo kanye nesimo sokusebenza.

1. Ama-conductor ethusi (asetshenziswa kakhulu ezimbonini ezintsha zamandla, ugesi kanye nokulawula izimboni)

Ububanzi obujwayelekile obuhle: 15%–25% (izinga lokucindezela) / 75%–85% (isilinganiso sokucindezela)

Izimo ezihlukanisiwe:

Ugesi ophezulu ojwayelekile (6–95mm²): izinga lokucindezela elingu-18%–22%, ukumelana nokulinganisela kanye namandla.

Ugesi omkhulu kakhulu (120–400mm²): Isilinganiso sokucindezela esingu-22%–25%. Kudingeka ukucindezela okuphezulu ukuze kuphulwe izendlalelo ze-oxide.

Ukudlidliza okuvama kakhulu (izimoto zamandla amasha / izitimela): isilinganiso sokucindezelwa esingu-15%–20%, kuvimbela ukuphuka kwentambo yentambo ekucindezelweni ngokweqile.

 

2. Umqhubi we-aluminium (ikhebula likagesi / ibha yebhasi)

I-Aluminiyamu ithambekele ekungcolisweni futhi ayinakuguguleka kahle. Kudingeka isilinganiso sokucindezela esiphezulu ukuze kuphulwe ifilimu ye-oxide: isilinganiso sokucindezela esingu-30%–50%, isilinganiso sokucindezela esingu-50%–70%

 

3. Izinkomba Ezijwayelekile Zemboni

I-National Standard GB/T 14315-2008: Isilinganiso sokucindezela ikhebula lamandla 20%-30%

I-IEC 60352-2: Isilinganiso sokucindezela i-crimping esingenasoda esingu-15%–25%

I-USCAR-21 (Izinga Lezimoto): Isilinganiso Sokucindezela 15%–20%, isilinganiso esingenalutho＜10%

 

III. Imiphumela Yesilinganiso Sokucindezela Okuphezulu Kakhulu Noma Okuphansi

✅ Isilinganiso sokucindezela esiphansi (<15%)

Ukufakwa okuxekethile phakathi komqhubi kanye ne-terminal, ukuphakama okukhulu kokumelana kokuthinta. Ukukhiqiza ukushisa okukhulu ngaphansi kombane ophezulu kanye nokwenyuka kwezinga lokushisa okungaphezu kuka-50℃.

Amandla okukhipha anganele, angaphansi kuka-80% wenani elijwayelekile, athambekele ekukhululekeni nasekuweni lapho kudlidliza.

Izikhala ezinkulu zivumela ukungena komswakama nothuli, okusheshisa ukugqwala nokubola.

✅ Isilinganiso sokucindezela okuphezulu kakhulu (>30%)

Ukuguquguquka ngokweqile noma ukuphuka kwezintambo zethusi, ukunciphisa amandla okuthwala ugesi.

Ukuqhekeka kodonga lwetheminali kanye nokuguquguquka okuholela ekulahlekelweni kwamandla omshini.

Ukugxila kokucindezeleka kwendawo kubangela ukuqhekeka ngaphansi kokukhula nokuncipha kokushisa kwesikhathi eside.

 

IV. Izici Ezintathu Eziyinhloko Zokunquma Isilinganiso Sokucindezela Esifanele

1. Izinto zomqhubi

Ithusi: Ukuqina okuhle, isilinganiso sokucindezela esingu-15%-25%

I-Aluminium: Isendlalelo se-oxide eqinile, isilinganiso sokucindezelwa esingu-30%-50%

I-aluminium embozwe ngethusi: Ububanzi obuphakathi, isilinganiso sokucindezela 20%-30%

 

2. Uhlobo lwetheminali

I-Tube terminal (OT/UT): isilinganiso sokucindezela esingu-18%–22%, kuthandwa i-hexagonal die

Itheminali evulekile (SC): isilinganiso sokucindezelwa esingu-20%–25%, kudingeka unqenqema oluvulekile oluncane

Itheminali entsha yamandla aphezulu kagesi (LV): isilinganiso sokucindezelwa esingu-15%–20%, umklamo ovimbela ukuqhekeka kwentambo

 

3. Amathuluzi okugoqa kanye nama-dies

Ama-pliers e-hydraulic crimping (16–24t): Afanelekela isilinganiso sokucindezela esizinzile esingu-6–400mm², 20%–25%

Idayi eliyi-hexagonal: Ukucindezeleka okufanayo, iphutha lokucindezela＜±2%, ukukhetha okuthandwayo

Idayi eliyindilinga: Ukusetshenziswa okulula kuphela, iphutha elikhulu ±5%, akukhuthazwa kumandla kagesi amakhulu kakhulu

 

V. Ukusebenza Okusebenzayo: Ukulawulwa Kwesilinganiso Sokucindezela kanye Nokuhlolwa Kwekhwalithi

1. Izinqubo Zokulawula Ukunemba

Ukufana kwezincazelo: Qondanisa ama-terminal, ama-dies kanye ne-cable cross-section eyodwa kuya kwenye

Ukwelashwa kokukhumula: Ubude bokukhumula bulingana nokujula kwe-ferrule kanye no-1-2mm, gcina imicu iphelele ngaphandle kwe-oxidation noma ama-burrs

Ukusetshenziswa kwamafutha okuhambisa umoya: Faka amafutha ahlanganisiwe kuma-conductor ethusi kanye ne-grease ekhethekile kuma-conductor e-aluminium ukuze ususe ifilimu ye-oxide

Ukusebenza kokubopha: Faka umqhubi ngokugcwele, ucindezele inani elilinganiselwe, ubambe ingcindezi imizuzwana emi-3-5, ubambe izikhundla ezi-2-3

Ukuqinisekiswa kokucindezela: Kala ububanzi bangaphandle ngemva kokugoba, iphutha lesilinganiso sokulawula ngaphakathi kwe-±2%

 

2. Izindlela Zokuhlola Ikhwalithi Ezidingekayo

Ukubukeka: Akukho mifantu, ukuvuvukala noma abaqhubi abaveziwe, ukugoba okufanayo

Ubukhulu: Ukuphambuka kobubanzi bangaphandle ≤±5%, isilinganiso sokucindezela ngaphakathi kobubanzi obubekiwe

Ugesi: Ukumelana kokuthintana ≤1.1 izikhathi kunomqhubi wobude obulinganayo, ukunyuka kwezinga lokushisa ≤30℃ ngemva kokuhlolwa kwamandla aphezulu kwehora eli-1

Okwemishini: Amandla okudonsa ahlangabezana nezindinganiso (umqhubi onezintambo ≥80N), akukho ukuxega noma imicu ephukile

 

VI. Isifinyezo: Izibalo Eziyinhloko Zokugoba Kwamandla Aphezulu

Umqhubi wethusi (6–400mm²): Isilinganiso sokucindezelwa esifanele esingu-18%–22%, isilinganiso sokucindezelwa esingu-78%–82%

Umqhubi we-aluminium: Isilinganiso sokucindezela 30%–50%

Isimiso esiyinhloko: Gwema ukugoba okunganele noma okweqile. Ama-match dies, ukulawula okunembile kanye nokuhlolwa okuqinile ukuze kuqedwe izingozi zokuxhumeka okuxekethile.

Isixhumi samandla aphezulu se-AMASS sisebenzisa itheminali engakusiza ukuthi ugcine ukuxhumana okuzinzile ezimweni zohlelo lokusebenza njengokudlidliza kwamandla aphezulu, imiphumela ephindaphindwayo yokushisa okuphezulu nokuphansi, ivolumu encane, kanye namandla aphezulu.
