Umkhawulo wesine yisitifiketi. Uma iphaneli isesikhungweni esilawulwayo, amabhlogo esiphetho esishintshayo kumele abe namamaki afanayo nalawo okuqala. Abakhi bephaneli kufanele futhi baqinisekise ukuthi i-PCB assembly iyahlangabezana I-IPC-A-610 amazinga okwamukelwa kwamajoyinti e-solder kanye nokufakwa kwezingxenye, njengoba ibhulokhi yesiphelo ithembeke kuphela njenge-PCB efakwa kuyo. Ibhulokhi yesiphelo se-PCB ye-pitch engu-5.0mm enesilinganiso esingu-150A kanye nesitifiketi esiphindwe kabili ngokuvamile iyindlela kuphela ehlangabezana nazo zonke izithiyo ezine ngesikhathi esisodwa. Yingakho kuyinto ejwayelekile yokusungula izinto kubasabalalisi abakhonza imakethe yokulungisa izimboni.

Imibuzo Evame Ukubuzwa

Iyini igeyiji yentambo ephezulu kakhulu yebhulokhi yesiphelo sephimbo elingu-5.0mm?

Amabhulokhi amaningi esikulufo se-PCB se-pitch esingu-5.0mm amukela ama-conductor afinyelela ku-10AWG (6mm²). Amanye amachungechunge anezindawo ezinwetshiwe amukela u-8AWG (10mm²), kodwa ububanzi obujwayelekile bungu-14AWG kuya ku-10AWG. Hlola ishidi ledatha elithile lobubanzi bezintambo.

Ngingawasebenzisa yini ama-ferrule anama-screw terminal blocks?

Yebo. Ama-ferrule athuthukisa ikhwalithi yokuphela kwama-conductor abambekile futhi avimbele ukuqhekeka kwe-strand. Indlela yokubopha izikulufo kumabhulokhi amaningi e-pitch angu-5.0mm yenzelwe ukwamukela ama-conductor abambekile ngaphandle kokuguqulwa. Ububanzi be-ferrule kumele bufane nobubanzi bentambo ye-terminal block.

Kungani ibhulokhi yami yokugcina isebenza kahle ku-80A uma ilinganiselwe ku-150A?

Isilinganiso se-150A sithatha izimo ezithile: i-ambient engu-40°C, ukufakwa kwesendlalelo esisodwa, kanye ne-torque efanele. Uma iphaneli igcwele, i-ambient iphakeme, noma i-torque ingalungile, umthamo wangempela uyehla. Linganisa izinga lokushisa nge-thermocouple endaweni yokuxhumana. Uma idlula ukuphakama okungu-45°C ngaphezu kwe-ambient, hlola izimo zokufaka ngaphambi kokusola umkhiqizo.

Ingabe ngidinga isitifiketi esiphindwe kabili sokuthumela eMexico?

IMexico iyaqaphela kokubili amazinga e-NOM kanye namazinga omhlaba wonke. Emishinini yezimboni, isitifiketi se-NOM siyadingeka, kodwa ibhulokhi yokugcina enokuqashelwa kwe-UL ingasetshenziswa njengengxenye eyaziwayo ekuhlanganisweni okuqinisekiswe yi-NOM. Imfuneko ethile incike esigabeni somkhiqizo wokugcina. Xhumana nenhlangano yesitifiketi yendawo ukuze uthole isiqondiso esiqondile.

Yisiphi isikulufi se-torque okufanele ngisisebenzise kumabhulokhi e-terminal e-pitch angu-5.0mm?

Isikulufi se-torque esilinganisiwe esinobubanzi obungu-0.1 kuya ku-1.0 Nm siyafaneleka. Incazelo evamile ingu-0.5 kuya ku-0.8 Nm. Ungasebenzisi umshayeli wamandla one-slip clutch ngaphandle kokuthi i-clutch ilinganisiwe futhi iqinisekisiwe, ngoba ukudlidliza okuvela kumshayeli kungakhulula ama-terminal aseduze.

Izinkomba Zomkhiqizo

Amabhulokhi okugcina okuxoxwe ngawo kulesi sihloko atholakala kwa-Ningbo J-Guang Electronics. Ibhulokhi yesikulufu se-PCB 301-5.0 Uchungechunge lune-pitch engu-5.0mm, umthamo wamanje ongu-150A, kanye nokuphela kwe-screw clamp okufanelekela izinhlelo zokusebenza zokusatshalaliswa kwamandla ezimboni. Ukuze uthole uhla oluphelele lwemikhiqizo, kufaka phakathi ama-pitch ahlukile kanye nezilinganiso zamanje, vakashela i- ikhathalogi yomkhiqizo.
