Mawaya akuwuluka mu thiransifoma

Mawaya owuluka, makhoma omwe amatsogolera kuchokera pamwamba pathiransifoma, nthawi zambiri amakhala ndi insulated ndi manja.

Anthu ambiri sangachitire mwina koma kukhala ndi funso:chifukwa chiyani thiransifoma imakhala ndi zowongolera zowuluka?

Choyamba, thiransifoma kapangidwe zowulukira mawaya, ndi kukwaniritsa zofunika chitetezo. Nthawi zambiri, ma transfoma amachita flywire, ndi achiwiri. Ena thiransifoma mafupa si chitetezo mafupa, sangathe kukumana ndi zofunika chitetezo, ngati yachiwiri mwachindunji atapachikidwa pa chigoba Pin mapazi, ndithudi sangadutse chitsimikizo chitetezo. Kugwiritsa ntchito mawaya owuluka, ndikosavuta kukwaniritsa cholinga ichi.

Pofuna kuchepetsa danga wotanganidwa bolodi thiransifoma, pa PCB, thiransifoma pulayimale ndi mawaya zowuluka, nthawi zambiri komanso slotted, kuwonjezera mtunda pakati pa awiri, kuti akwaniritse zofunika chitetezo, kuchepetsa cholinga cha PCB. Izi ndi za mankhwala omalizidwa apamwamba kwambiri, voliyumu yaying'ono, ali ndi ntchito yofunikira.

Kachiwiri, yachiwiri linanena bungwe panopa lalikulu, wandiweyani waya awiri, ntchito zowuluka mawaya atsogolere kukwaniritsidwa kwa ndondomeko.Pakuti mawaya insulated, kuuma ndi lalikulu kwambiri, makamaka kuposa 0.7mm waya awiri, kudzera pa casing ikulendewera Pin n'kovuta, komanso zosavuta chifukwa mapiringidzo Pin phazi zokhotakhota, pambuyo soldering apamwamba kuposa chigoba pivot, kuwotcherera zabodza ndi nkhani zina. Transformer pogwiritsa ntchito mawaya owuluka, mutha kupewa zovuta zomwe zingachitike.

Chachitatu, mawaya owuluka angagwiritsidwe ntchito kuwonjezera mapazi a PIN ya thiransifoma.Izi ndizofala kwambiri pazinthu zamafupa, komanso zina zopindika zachiwiri ndizochulukirapo, nambala ya PIN yomwe ilipo sikokwanira kugwiritsa ntchito mlanduwo, kudzera pa flywire ikhoza kukwaniritsidwa kuti muwonjezere kuchuluka kwa PIN.

Komabe, ndiyenera kudziwa kuti, ngakhale zabwino za mawaya owuluka, koma pali zovuta zina:

Ngati pali mawaya akuwuluka muthiransifoma, kuzimitsa kwathunthu kwa phukusi la waya kumakhala kovuta kwambiri. Popeza mawaya owuluka samakhazikika koyambirira ndi kumapeto, ngakhale mapiritsi a semi-automatic, poyerekeza ndi zida zonse za PIN zosinthira, mphamvuyo idzachepetsedwa.

Pankhani yoyesera, kukhalapo kwa mawaya owuluka kumafuna kuwonjezeredwa kwazitsulo zowonjezera zoyesera kuti zitsimikizire kuti mayesowo akuyenda bwino. Kuti atsogolere kuyika kwa PCB, mawaya owuluka a thiransifoma, komanso amafunika kusinthidwa kukhala mawonekedwe ena, zidzatsogolera kuti njira yonse yopanga thiransifoma ikhale yovuta.

Kwa mafakitale a PCB, kukhalapo kwa thiransifoma zowulukira kumakhudza kwambiri mphamvu ya pulagi ya thiransifoma. Chifukwa cha kusinthasintha kwa flywire, nthawi zambiri pali mapulagi-ins sali m'malo, zomwe zingayambitse flywire ndi PCB pakati pa kukhalapo kwa weld opanda kanthu, weld zabodza ndi zochitika zina zoipa. Ngati chowotchereracho ndi chotalika kwambiri, mafunde a soldering pambuyo pa kuwotcherera ayeneranso kudula phazi.

Kuphatikiza apo, mawaya ena owuluka amayenera kusiyanitsa pakati ndi kunja kwa mzere (nthawi zambiri wokhala ndi chotchinga choyera ndi chakuda), kuti apewe mawaya owuluka pulagi-mu plug-in reverse, zomwe zimapangitsa kutuluka kwachilendo.

Powombetsa mkota,mawaya owuluka a thiransifoma amatha kukhala osavuta kukwaniritsa zofunikira zachitetezo, amathandizira kukwaniritsidwa kwa njira yolumikizira waya, kuwonjezera kuchuluka kwa PIN, koma kukhalapo kwa mawaya owuluka, komanso kumapangitsa kuti pakhale ndalama zambiri zopangira ndi kukhazikitsa.Chifukwa chake, mu kapangidwe ka thiransifoma, kufunikira kosankha koyenera. Nthawi zambiri, thiransifoma imatha kuchepetsa mawaya owuluka, kuchepetsa kapangidwe ka waya wowuluka.
