TL;DR — Zofunikira Zopezera Zinthu Zachiwiri
- Unyolo woperekera zinthu wa terminal block imodzi uli ndi mwayi woti zinthu zisokonezeke pachaka wa 12-18%. — kusowa kwa zinthu zopangira, kusokonekera kwa njira zopangira, ndi kuchedwa kwa kayendetsedwe ka zinthu zonse zimapangitsa pafupifupi gawo limodzi mwa magawo atatu a chiopsezocho.
- Kupeza zinthu ziwiri ndi wogulitsa wina woyenerera kumachepetsa kusokonezeka komwe kungachitike ndi zosakwana 3% — koma pokhapokha ngati wogulitsa wachiwiri wayesedwa kale, wavomerezedwa kale, ndipo akusunga unyolo wosiyana wa zinthu zopangira.
- Njira yophunzirira imatenga milungu 8-12 — zomwe zikutanthauza kuti muyenera kuyamba kampani isanathe kupereka chithandizo choyamba. 70% ya njira zopezera zinthu ziwiri zimayamba mochedwa kwambiri.
- Zotsatira za mtengo wa kugula zinthu ziwiri nthawi zambiri zimakhala +5-8% pamitengo ya mayunitsi pa gawo la ogulitsa ena, ndalama zomwe zimapezedwa zoyambira $25,000 mpaka $100,000 patsiku kwa ma OEM apakatikati odziyimira pawokha.
Chifukwa Chake Timalimbikitsa Kupeza Zinthu Zawiri Musanazifune
Mu zomwe takumana nazo popereka ma block a sitima za DIN kwa opanga magalimoto ndi omanga mapanelo padziko lonse lapansi, makampani omwe amakumana ndi kusokonekera kwa unyolo woperekera zinthu ali ndi khalidwe limodzi lofanana: amayenerera wogulitsa wina panthawi yantchito wamba - osati panthawi yamavuto. Chifukwa njira yoyenerera wogulitsa malo atsopano ogwirira ntchito — kuphatikizapo kuvomereza zitsanzo, kuyesa kwamagetsi pa IEC 60947-7-1, kutsimikizira kuyanjana kwa magawo, ndi kuwunika kupanga — kumatenga milungu 8-12, chifukwa chake kampani yomwe imayamba njirayi ikalengeza kuti kampaniyo yachedwa kwa milungu 16, imakhala itataya kale ntchito yake kwa milungu 8-12. Masamuwo ndi osakhululuka.
Ndaona izi zikuchitika mobwerezabwereza. Kampani yogulitsa ma terminal block ku Europe ku Germany imayimitsa kupanga kwa milungu 6 chifukwa cha kusefukira kwa madzi pamalo awo opangira jakisoni. Kampani ya OEM ili ndi zinthu zosungira ma terminal block kwa milungu 8. Izi zikumveka ngati buffer kwa milungu iwiri - mpaka mutazindikira kuti kuyenerera wogulitsa watsopano kumatenga milungu 12. Kampani ya OEM imatha ma terminal block pa sabata 8, imayimitsa ma control panels pa sabata 9, ndipo imataya ndalama zokwana $1.2 miliyoni mkati mwa masabata 4. Kampani yachiwiri yomwe pamapeto pake imayenerera - kampani yathu - ikanatha kutumiza zinthu zoyenerera pa sabata 8 ngati njira yoyenerera ikanayamba milungu 12 m'mbuyomo. Chifukwa mtengo woti munthu wina ayenerere kusankhidwa ndi wopereka chithandizo chachiwiri ndi pafupifupi $15,000-25,000 (maoda a zitsanzo, mayeso, maulendo owunikira), chifukwa chake kuwerengera kwa ROI ndikosavuta: $20,000 yomwe imayikidwa mu ziyeneretso imaletsa kutayika kwa ndalama za $1.2 miliyoni - phindu la 60:1. Komabe 70% ya OEMs omwe timagwira nawo ntchito amayamba ntchitoyi pokhapokha chisokonezo chitachitika.
Zachuma za Kupereka kwa Magwero Okhaokha a Terminal Block
Ma block a terminal akuoneka ngati zigawo za katundu — masenti ochepa mpaka madola ochepa pa mtengo uliwonse, ogulidwa ndi chikwi chimodzi. Kuwona kwa katundu kumeneku kumabweretsa lingaliro loopsa: kuti ngati Supplier A sangathe kupereka, Supplier B akhoza kuyambiranso ntchito mkati mwa milungu ingapo. Zoona zake n'zakuti ma block a terminal sangasinthidwe popanda ziyeneretso.
Ma block a sitima ya DIN ayenera kukwaniritsa zofunikira zamagetsi, makina, ndi miyeso yosiyanasiyana zomwe zimasiyana malinga ndi momwe zimagwiritsidwira ntchito. Block ya sitima yolowera yomwe imayesedwa kuti ndi 32A/800V pa IEC 60947-7-1 iyenera kusonyeza: mphamvu ya dielectric ya 2,500V kwa mphindi imodzi, mphamvu yopirira nthawi yochepa ya 1.5 kA kwa sekondi imodzi, mphamvu yolumikizira yokwanira kusunga kukana kokhudzana ndi pansi pa 0.5 mΩ pambuyo pa ma 500 thermal cycles, komanso kugwirizana kwa miyeso ndi DIN rail profile (TS 35 pa EN 60715) ndi ma block a terminal oyandikana nawo mu assembly. Chifukwa makhalidwe amenewa amadalira aloyi yamkuwa yeniyeni, mtundu wa chitsulo cha masika, ndi kapangidwe ka polyamide komwe kamagwiritsidwa ntchito ndi wopanga aliyense., motero ma terminal block ochokera kwa ogulitsa osiyanasiyana ndi ofanana pamagetsi koma safanana — ndipo satifiketi ya OEM yoyesera mtundu (nthawi zambiri IEC 61439 ya switchgear yotsika mphamvu ndi ma controlgear assemblies) imagwira ntchito kokha pazigawo zinazake zomwe zalembedwa mu lipoti la mtundu woyesera.
Izi zikutanthauza kuti kusintha ogulitsa ma terminal block si chisankho chogula - ndi chisankho chaukadaulo chomwe chimafuna kutsimikizira kwa mtundu kapena kutsimikiziranso. Nthawi yotsimikiziranso ya gulu lowongolera ndi wogulitsa watsopano wa terminal block imayambira pa masabata 4 (ngati block yatsopanoyo ikufanana ndi yoyamba ndipo bungwe lotsimikizira likuvomereza mfundo yofanana) mpaka masabata 16 (ngati kuyezetsanso kwathunthu kukufunika). Chifukwa nthawi yotsimikiziranso nthawi zambiri imapitirira nthawi yomwe kusokonezeka kwa zinthu kukuchitika., chifukwa chake njira yokhayo yothandiza ndikutsimikizira kuti wogulitsa wachiwiri akuyenera kuyenerera kusokoneza kusanachitike - kusunga udindo wa wogulitsa wogwira ntchito komanso wovomerezeka womwe umalola kuyika oda nthawi yomweyo pomwe wogulitsa wamkulu sangathe kupereka.
