Iimpawu kunye nokucalulwa komonakalo wokuchasana

Ngokuqhelekileyo kubonakala ukuba abaninzi abaqalayo baphosa ukuchasana xa kulungiswa isiphaluka, kwaye ichithwa kwaye i-welded.Enyanisweni, kukho ukulungiswa okuninzi.Logama nje uqonda iimpawu zomonakalo wokuchasa, akufuneki uchithe ixesha elininzi.

I-Resistor yeyona nto ininzi kwizixhobo zombane, kodwa ayilona candelo elinomlinganiselo ophezulu womonakalo.Isekethe evulekileyo yolona hlobo luqhelekileyo lomonakalo wokuchasana.Kunqabile ukuba uxhathiso lube lukhulu, kwaye kunqabile ukuba uxhathiso lube luncinci.Eziqhelekileyo ziquka i-carbon film resistors, i-resistors yefilimu yensimbi, i-resistors yenxeba yocingo kunye ne-inshurensi yomshuwalense.

Iindidi ezimbini zokuqala zokuxhathisa zezona zisetyenziswa kakhulu.Enye yeempawu zomonakalo wabo ngumlinganiselo ophezulu womonakalo wokuchasana okuphantsi (ngaphantsi kwe-100Ω) kunye nokuchasana okuphezulu (ngaphezu kwe-100kΩ), kunye nokuchasana okuphakathi (njengamakhulu ohms ukuya kumashumi e-kiloohms) Umonakalo omncinci kakhulu;okwesibini, xa i-resistant-resistant-resistant yonakele, ihlala itshiswa kwaye imnyama, ekulula ukuyifumana, ngelixa i-resistant-resistant-resistant inqabile.

Izichasi zeWirewound zihlala zisetyenziselwa umda ophezulu wangoku, kwaye ukuchasana akukhulu.Xa i-cylindrical wire resistors itshisiwe, ezinye zijika zibemnyama okanye umphezulu uya kugqabhuka okanye uqhekeke, kwaye ezinye aziyi kuba nazikhondo.Izichasi zesamente luhlobo lwezixhasi zenxeba zocingo, ezinokuphuka xa zitshisiwe, ngaphandle koko akuyi kubakho zimpawu ezibonakalayo.Xa i-resistor ye-fuse ivutha, isiqwenga solusu siya kugqabhuka phezu komhlaba, kwaye ezinye azikho umkhondo, kodwa aziyi kutshiswa okanye zibe mnyama.Ngokwezi mpawu zingentla, unokugxila ekujongeni ukuchasana kwaye ufumane ngokukhawuleza ukuchasana okonakele.

Ngokweempawu ezidweliswe apha ngasentla, sinokuqala sijonge ukuba ngaba abaxhathisi abaphantsi kwibhodi yesekethe banazo naziphi na iimpawu ezivuthayo ezimnyama, kwaye ngoko ngokweempawu uninzi lwabaxhathisi bavulekileyo okanye ukuxhathisa kuba nkulu xa abaxhathisi yonakele, kunye ne-resistance ephezulu yokuchasa yonakaliswa ngokulula.Singasebenzisa i-multimeter ukulinganisa ngokuthe ngqo ukuchasana kuzo zombini iziphelo ze-resistance high-resistance kwibhodi yesiphaluka.Ukuba ukuchasana okulinganisiweyo kukhulu kunokuxhatshazwa okuqhelekileyo, ukuchasana kufuneka konakaliswe (qaphela ukuba ukuchasana kuzinzile emva kokuba umboniso uzinzile. Ekugqibeleni, ngenxa yokuba kunokubakho izinto ezihambelanayo ze-capacitive kwisiphaluka, kukho inkqubo yokuhlawula kunye nokukhupha. ), ukuba ukuchasana okulinganisiweyo kuncinci kunokuxhatshazwa okuqhelekileyo, ngokuqhelekileyo kuhoywa.Ngale ndlela, ukuchasana konke kwibhodi yesiphaluka kulinganiswa kanye, nokuba iwaka "libulewe ngokungalunganga", umntu akayi kuphoswa.
