Kukana Kwambiri kwa Kukhudzana ndi WTB Connector: Zomwe Zimayambitsa, Kukonza, ndi Momwe Mungapewere
Ngati mudakumanapo ndi zizindikiro zosakhalitsa, zolumikizira zotentha kwambiri, kapena kulephera kwathunthu kwa chipangizo, mwina mwakumana kale ndi vuto lobisika: Cholumikizira cha WTB Kukana kwambiri kukhudzana ndi chipangizocho. Ndi limodzi mwa mavuto omwe nthawi zambiri samawonekera pa mayeso oyambira opitilira koma amatha kuwononga magwiridwe antchito pang'onopang'ono pakapita nthawi.
Mu bukhuli, ndikufotokozerani zomwe zimayambitsa kukana kwakukulu kwa waya ku waya.Cholumikizira cha Bodis, momwe mungazindikire isanabweretse mavuto enieni, ndipo - chofunika kwambiri - zomwe mungachite kuti mukonze ndikupewa. Palibe zinthu zopanda pake, koma thandizo lothandiza kwa mainjiniya, akatswiri, ndi ogula omwe akufuna kulumikizana kodalirika.
Kodi "Kukana Kwambiri Kukhudzana" Kumatanthauza Chiyani mu WTB Connector?
Cholumikizira chilichonse cha WTB (waya kupita ku bolodi) chimapangidwa kuti chikhale ndi mphamvu zochepa zamagetsi pa malo olumikizirana - nthawi zambiri chimakhala pamtunda wa milliohm. Kukana kumeneko kukapitirira zomwe zafotokozedwa, mumapeza mphamvu zambiri zolumikizirana. Zotsatira zake mwachangu ndi ziti? Kutsika kwa mphamvu yamagetsi, kuchulukana kwa kutentha, kusokonekera kwa chizindikiro, ndipo pamapeto pake, ma pulasitiki osungunuka kapena ma pini oyaka.
Taganizirani ngati chitoliro mu payipi ya m'munda: madzi ambiri (madzi) akadali kuyenda, koma chitolirocho chimakhala chotentha, mphamvu imatsika, ndipo chilichonse chomwe chili pansi pa mtsinje chimawonongeka.
Chifukwa chiyani Cholumikizira cha WTB Kodi Kukana Kwambiri Kumachitika?
Kuchokera ku kulephera kwa ntchito zenizeni ndi mayeso a labu, izi ndi zifukwa zodziwika bwino:
1. Kuipitsidwa ndi okosijeni kapena pamwamba – Ngakhale filimu yopyapyala ya ma oxide, sulfide, kapena zotsalira zopangira zinthu zimatha kukweza kwambiri kukana kwa zinthu. Izi zimachitika makamaka ndi malo otetezedwa ndi zitini m'malo ozizira kapena oipitsidwa.
2. Mphamvu yokwanira yachibadwa - Gawo lofanana ndi kasupe la gawo lachikazi lomaliza limataya mphamvu yake pakapita nthawi (kapena silinapangidwe bwino kuyambira pachiyambi). Mphamvu yocheperako yachibadwa imatanthauza malo ochepa olumikizirana ndi ma microscopic, zomwe zimapangitsa kuti pakhale kukana kwakukulu.
3. Kusakhazikika bwino kwa mgwirizano kapena kuyika kosakwanira - Pamene Waya Pokwelera Ngati sichili bwino m'nyumba, kapena chotchingira nyumba sichinatsekedwe, malo olumikizirana amachepa. Ichi ndi cholakwika chokhazikika chomangirira.
4. Kukhudzana ndi zinthu zosweka kapena zosweka - Kugwedezeka, kutentha, kapena kubwerezabwereza kwa zinthu zosweka kungayambitse dzimbiri. Zinyalala zazing'ono zimasonkhanitsidwa, ndikupanga zigawo zoteteza kutentha.
5. Chingwe choyesera waya cholakwika kapena chingwe chowonongeka - Chingwe chosasunthika kapena kugwiritsa ntchito waya woonda kwambiri ku terminal kumapangitsa kuti pakhale malo obisika otetezera mkati mwa chotenthetsera.
Momwe Mungadziwire Ngati Muli ndi Vuto Lolimba Lokhudzana ndi Kulumikizana
Sikuti nthawi zonse mumafunika zida zodula za labu. Nazi zizindikiro zenizeni:
- Kutentha kosazolowereka pa cholumikizira - chigwireni mukachigwiritsa ntchito bwino. Ngati chili chotentha, ndiye kuti mphamvuyo yatayika.
- Kulephera kwanthawi ndi nthawi komwe kumatha mukasuntha mawaya.
- Kutsika kwa voteji kudutsa cholumikizira: yezani kuchokera pa waya kupita pa bolodi lomwe lili ndi katundu. Kuposa 50 mV kwa chizindikiro cha mphamvu yochepa kapena kupitirira 100 mV kwa kukhudzana kwa mphamvu ndikokayikitsa.
- Kuyang'ana m'maso - malo otsetsereka amdima kapena osinthika, nyumba zosungunuka mozungulira pini imodzi, kapena fumbi lakuda.
Kuti muyese bwino, gwiritsani ntchito milliohmmeter (njira ya Kelvin ya waya zinayi). Yerekezerani kuwerenga kwanu ndi deta ya cholumikizira. Ngati ili yokwera ndi 20–30% kuposa kuchuluka komwe kwatchulidwa, ndiye kuti muli kale pamalo oopsa.
Momwe Mungakonzere WTB Connector High Contact Resistance
Mukatsimikizira vutoli, nayi njira yothandiza:
- Tsukani zolumikizirana - Kuti muchepetse kukhuthala, gwiritsani ntchito chotsukira chamagetsi (DeoxIT kapena chofanana nacho) ndi burashi yaying'ono. Musagwiritse ntchito zinthu zopukutira monga sandpaper - zimachotsa ma plating ndikupangitsa zinthu kukhala zoyipa kwambiri.
- Kuyang'anira kusunga - Pa ma terminal achikazi, limbitsani pang'onopang'ono kasupe wolumikizana nawo pogwiritsa ntchito chosankha chabwino. Ichi ndi chokonza kwakanthawi; ndibwino kusintha.
- Konzaninso kapena kusintha – Ngati chogwiriracho chikuoneka chofooka kapena waya watuluka mosavuta, dulani chogwiriracho ndikuchikoka chatsopano ndi chida choyenera. Musagwiritsenso ntchito chogwiriracho chowonongeka.
- Kusintha cholumikizira chonse - Ngati nyumba ya pulasitiki yawonongeka ndi kutentha kapena ngati yakhudzidwa ndi zinthu zingapo, sinthani cholumikizira chonsecho. Kusakaniza ma terminal akale ndi atsopano nthawi zambiri sikugwira ntchito bwino.
Chofunika: Ngati mutu wa bolodi ukuwonetsa zizindikiro za kusweka kapena golide, usintheninso. Kukana kwambiri nthawi zambiri kumawononga mbali zonse ziwiri.
Momwe Mungapewere Kukana Kwambiri kwa WTB Connector (Kwabwino)
Kusankha cholumikizira choyenera ndikuchigwiritsa ntchito bwino kumateteza mavuto osatha. Izi ndi zomwe inu (monga wogula kapena wopanga) mungachite:
1. Sankhani pulasitala yoyenera - Golide ndi wabwino kwambiri pazizindikiro zochepa komanso malo ovuta (opanda dzimbiri). Chitini ndi chotsika mtengo koma chimafuna mphamvu yachibadwa komanso kukhazikika. Ngati chogwirira chanu chikugwedezeka kapena chikuwoneka cholumikizidwa pafupipafupi, sankhani golide pa golide kapena golide pa palladium.
2. Tchulani mphamvu yokwanira yanthawi zonse - Yang'anani zolumikizira zokhala ndi ≥ 50 g pa kukhudzana kulikonse kuti mupange chitini, ≥ 30 g kuti mupeze golide. Zolumikizira zotsika mtengo nthawi zambiri sizikupezeka apa.
3. Yang'anirani nthawi yolumikizirana - Zolumikizirana zophimbidwa ndi zitini nthawi zambiri zimakhala ndi nthawi ya 25-50. Golide amatha kupitirira 500 mosamala. Ngati chinthu chanu chikufunika kuchotsedwa nthawi zambiri, pangani nthawi yolumikizirana nthawi zambiri.
4. Gwiritsani ntchito malo otsekedwa kapena otetezedwa - Pa malo okhala ndi fumbi, chinyezi, kapena mchere, sankhani zolumikizira zokhala ndi ma gasket a rabara kapena zophikira. Kapena onjezerani chophimba chofanana pamwamba pa malo olumikizirana.
5. Ogwira ntchito yokonza zinthu - Mavuto ambiri olimbana ndi vuto la kutsekeka kwa chitoliro amachitika nthawi yokonza ndi kuyika chitolirocho. Gwiritsani ntchito chida choyesera kukoka chitolirocho ndi ma gauge osapita. Tsimikizirani kuti latch yalowa bwino pogwiritsa ntchito njira yosavuta yokoka chitolirocho.
6. Kuwotcha ndi kutentha - Ngati mukupanga chinthu chofunikira kwambiri, chitani kuwotcha kwakanthawi kochepa (monga maola 24 pamagetsi oyesedwa) kenako muyesenso kukana kukhudzana ndi magetsi. Zimasonyeza kuti magetsi sakukhazikika.
Mawu Ofulumira kwa Ogula ndi Mainjiniya Abwino
Mukafuna zolumikizira za WTB, musayerekezere mtengo pa chidutswa chilichonse. Funsani deta yokhazikika ya kukana kulumikizana - osati mitengo yoyambirira yokha, komanso pambuyo pa mayeso a kutentha ndi chinyezi kapena kugwedezeka. Zolumikizira zambiri zotsika mtengo zimayamba bwino koma zimakhala zolimba kwambiri patatha miyezi ingapo mukugwira ntchito.
Komanso, onani ngati wopanga watchula njira yoyesera (monga EIA‑364‑23). Wogulitsa wodalirika adzapereka ma miliyoni a miliyoni ndi magetsi oyesera omwe ali ndi mphamvu yodziwika bwino komanso magetsi otseguka. Pewani mawu osamveka bwino akuti "kukana kotsika".
Kutenga Komaliza
Cholumikizira cha WTB cholimba kwambiri sikuti kulephera kwachinsinsi kumachitika - nthawi zambiri kumachitika chifukwa cha okosijeni, mphamvu yochepa, kulephera kugwira bwino ntchito, kapena kutsekeka. Nkhani yabwino: mutha kuzizindikira msanga ndi mayeso osavuta ochepetsa mphamvu yamagetsi, ndipo mutha kuziletsa posankha pulasitala yoyenera ndikutsatira njira zoyenera zosonkhanitsira.
Nthawi ina mukawona kulumikizana kwapakati kapena cholumikizira chofunda, musangosintha bolodi - yang'anani kaye kukana kwa kulumikizana. Mphindi zochepa ndi milliohmmeter zingapulumutse maola ambiri othamangitsa mizimu.
Kodi muli ndi mtundu kapena pulogalamu yolumikizira ya WTB? Yang'anani zomwe zili mu "contact resistance" ya datasheet yake ndipo yesani yanu lero. Mungadabwe ndi zomwe mungapeze.
