Pa ntchito zogwedezeka kwambiri, ubwino wodalirika umapangitsa kusiyana kwa mtengo kukhala kosafunikira.

Kodi ma terminal a masika a khola amatha kugwira ntchito ndi ma kondakitala a aluminiyamu?

Ma terminal ambiri a masika a masika amavoteledwa kuti azigwiritsidwa ntchito ndi ma conductor amkuwa okha. Aluminiyamu imafunika kuganiziridwa mwapadera chifukwa cha kuchuluka kwa kutentha komwe kumawonjezera komanso kapangidwe ka okosijeni. Opanga ena amapereka ma terminals ovoteledwa ndi aluminiyamu okhala ndi ma spring alloys ogwirizana ndi malo olumikizirana, koma izi sizinthu wamba. Nthawi zonse onetsetsani kuti kondakitala ikugwirizana ndi pepala la deta la wopanga musanatchule mawaya a aluminiyamu.

Kodi waya wokulirapo kwambiri wa ma terminal a masika a khola ndi wotani?

Malo okhazikika a masika a mafakitale okhala ndi malo okwana 0.08-16mm² (pafupifupi 28 AWG mpaka 6 AWG). Mitundu yamagetsi amphamvu imafikira 35mm² kapena 50mm² pakugwiritsa ntchito magetsi. Kuchuluka kwake kumasiyana malinga ndi wopanga ndi mndandanda wazinthu, choncho onetsetsani kuti mukutsatira ndondomeko yanu ya waya. Kwa ma conductor akuluakulu opitilira 50mm², ma block ogawa magetsi kapena ma bolt nthawi zambiri amakhala oyenera kuposa mapangidwe a masika a masika.

Kodi ma terminal a masika amagwira ntchito ndi ma bootlace ferrules?

Inde. Ma ferrule a Bootlace—okhala ndi ma crimp sleeves otetezedwa kapena osatetezedwa omwe amathetsa ma conductors osweka—amagwirizana mokwanira ndi ma terminals ambiri a masika. Kukula kwa ferrule kuli mkati mwa nthawi yogwirira ntchito ya masika, ndipo kumapeto kwake kosweka kumapereka malo oyera ozungulira omwe masika amagwira mofanana. Kugwiritsa ntchito ma ferrules kumalimbikitsidwa pa ma waya oyezera osakwana 2.5mm² m'malo ogwedezeka kuti chingwe chisasweke komanso kuti chikhale chogwirizana nthawi zonse.

Kodi malo osungiramo zinthu zakale m'khola la masika sagwedezeka?

Kusagwirizana kwa magetsi sikungagwedezeke kwenikweni. Malo olumikizira masika ndi a yosagwedezeka ku milingo yodziwika bwino ya kuuma, yomwe nthawi zambiri imatsimikiziridwa ndi IEC 60068-2-6 pa 5g, 5-150Hz. Kupitilira kuuma kumeneko, njira zina zowonjezera—monga mankhwala ophikira m'mbale, kuchepetsa kupsinjika kwa chingwe, kapena zomangira zodzipatula za kugwedezeka—zingafunike. Mafotokozedwe olondola si "osagwedezeka" koma "oyesedwa kugwedezeka mpaka kuuma kwa X kwa nthawi ya Y."

Kodi ndingatsimikize bwanji kuti malo osungiramo zinthu zakale ndi enieni osati abodza?

Ma block a zinthu zabodza ndi vuto lomwe likukulirakulira, makamaka m'misika yomwe malamulo okhwima okhudza kutumiza kunja. Zinthu zenizeni zili ndi zizindikiro za wopanga, manambala a malo ofunikira, ndi ziphaso zoyesera za anthu ena (UL, VDE, TÜV). Pemphani satifiketi mwachindunji kuchokera kwa wogulitsa wovomerezeka wa wopanga, osati kuchokera kwa wogulitsaNgati mtengo wake uli pansi pa 40% pamsika, mwina chinthucho ndi chabodza. Mtengo wa terminal yolephera pa mzere wopangira womwe ukuyenda bwino umaposa ndalama zomwe zasungidwa pogula zinthu zotsika mtengo.

Zolemba za Zamalonda

Kuti mudziwe mabuloko otsegulira makhola a masika omwe amapangidwira malo ogwirira ntchito zamafakitale omwe amagwedezeka kwambiri, onani tsamba lawebusayiti. kabukhu kathunthu ka zinthu. Mitundu yonseyi ikuphatikizapo malo otsetsereka a DIN omwe ali ndi ma spring cage omwe ali ndi DIN omwe ali ndi ma rail ratings kuyambira 2.5A mpaka 125A, ndipo waya umalandira kuyambira 0.08mm² mpaka 16mm², kuphatikizapo ma stranded ndi ferruled conductors.

Kuti muwone kufananiza kwa ma terminal ndi momwe mawaya olimba a conductor alili oyenera, onani PCT-211 DIN njanji yokankhira waya yolumikizira.
