I-Resistance wire luhlobo oluqhelekileyo lwecandelo lokumelana, kunye nomthwalo wayo ongaphezulu ubhekiselele kuxinzelelo lwangoku oluthwalwa kwindawo nganye yeyunithi. Ukubala ngokuchanekileyo umthwalo womphezulu wocingo oluchasayo lubalulekile ekuqinisekiseni ukusebenza kwawo okuqhelekileyo kunye nobomi benkonzo. Eli nqaku liza kwazisa indlela yokubala umthwalo womphezulu weingcingo zokumelana kunye nezilumkiso ezinxulumene nazo.

Okokuqala, kufuneka siqonde inkcazo yomthwalo womphezulu. Umthwalo womphezulu ubhekisa kuxinaniso lwangoku (A/cm ^ 2) oluthwalwa kwindawo nganye yeyunithi. Imelwe yifomula:

Umthwalo womphezulu=uxinano lwangoku/ummandla womphezulu

Ukubala umthwalo womphezulu wocingo lokumelana, okokuqala kufuneka sinqume ubuninzi bangoku. Uxinaniso lwangoku lubhekisa kumyinge wangoku odlulayo kwindawo enqamlezileyo yeyunithi. Inokubalwa ngokusekwe kwixabiso lokuxhathisa lezinto zocingo oluxhathisayo, amandla ombane ombane, kunye nobude bocingo lokuchasa, kusetyenziswa le fomula ilandelayo:

Uxinaniso lwangoku=voltage/(ixabiso lokuxhathisa x ubude)

Xa kubalwa ukuxinana kwangoku, la manqaku alandelayo kufuneka aqatshelwe:

1. Khetha ixabiso elifanelekileyo lokumelana: Ixabiso lokumelana nocingo lokumelana kufuneka lihambelane noxinano olufunekayo lwangoku. Ukuba ixabiso lokumelana lincinci kakhulu, ukuxinana kwangoku kunokuba kuphezulu kakhulu, kubangela ukuba ucingo lokumelana lugqithise okanye lutshise. Ngokuchasene noko, ixabiso eliphezulu lokuchasa linokukhokelela ekuxininiseni okuphantsi kwangoku kunye nokulahleka kwamandla okungonelanga. Ngoko ke, kuyimfuneko ukukhetha amaxabiso afanelekileyo okuchasa ngokusekelwe kwiimfuno ezithile zesicelo.

2. Qwalasela into yokhuseleko: Ukuze kuqinisekiswe ukusebenza okukhuselekileyo kocingo lokumelana, into ekhuselekileyo idla ngokuziswa xa kubalwa umthwalo womphezulu. Ubungakanani bemeko yokhuseleko buxhomekeke kwimeko yesicelo sangempela, kwaye ngokuqhelekileyo kucetyiswa ukuba ube phakathi kwe-1.5 kunye ne-2. Umthwalo wokugqibela womhlaba unokufumaneka ngokuphindaphinda into yokhuseleko ngokubalwa kobuninzi bangoku.

3. Nika ingqalelo kwimpembelelo yeqondo lokushisa kwixabiso lokumelana: Iingcingo ezichasayo ziya kuvelisa ukushisa ngexesha lokusebenza, okukhokelela ekunyuseni kweqondo lokushisa. Oku kuya kubangela utshintsho kwixabiso lokumelana nocingo lokumelana. Ngoko ke, xa ubala umthwalo womphezulu, kuyafuneka kwakhona ukuqwalasela ukuhluka kwexabiso lokumelana nokushisa. Ngokuqhelekileyo, i-coefficient yokushisa yezinto ezichasayo zingasetyenziselwa izibalo zokulungiswa.

Isishwankathelo, ukubala umthwalo womphezulu wocingo lokumelana kufuna kuqala ukugqiba ukuxinana kwangoku, kwaye emva koko unqume umthwalo wokugqibela wendawo ngokusekelwe kwizinto ezifana nokhuseleko kunye nokulungiswa kweqondo lokushisa. Ukubala okunengqiqo komthwalo womphezulu kunokuqinisekisa ukusebenza okuqhelekileyo kweengcingo zokumelana nokuphucula ubomi babo benkonzo.

Kuyafaneleka ukuba uqaphele ukuba oku ngasentla yindlela kuphela yokubala imithwalo yomhlaba kwaye ayisebenzi kuzo zonke iimeko. Kwiingcingo ezixhathisayo ezineemfuno ezizodwa, ezifana nezo zisetyenziswa kwiindawo ezithile zobushushu obuphezulu, iindlela zokubala ezikhethekileyo zingadinga ukusetyenziswa ngokweemeko ezithile. Kwizicelo ezisebenzayo, kucetyiswa ukuba udibane neengcali okanye ubhekisele kwimigangatho efanelekileyo yokubala kunye nokukhetha.

Xa usebenzisa iingcingo zokumelana, ngaphezu kokubala ngokuchanekileyo umthwalo womphezulu, kufuneka kuqatshelwe la manqaku alandelayo:

1. Iimeko ezilungileyo zokutshatyalaliswa kobushushu: Iingcingo ezichasayo zivelisa ukushisa ngexesha lokusebenza, ngoko ke kuyimfuneko ukuqinisekisa iimeko ezifanelekileyo zokutshatyalaliswa kobushushu ukuphepha iimpazamo okanye umonakalo obangelwa ukushisa okuphezulu.

2. Ukuthintela ukugqithiswa: Intambo yokumelana kufuneka isetyenziswe ngaphakathi koluhlu lomthwalo olinganisiweyo ukuze ugweme ukudlula ngokugqithisileyo ngoku, ukwenzela ukuthintela ukugqithiswa kokubangela iingxaki ezifana nokushisa kunye nokutshisa.

3. Ukuhlolwa rhoqo: Hlola rhoqo isimo sokusebenza kunye nokudibanisa kwentambo yokumelana nokuqinisekisa ukusebenza kwayo okuqhelekileyo, kwaye ngokukhawuleza ulungise okanye utshintshe naziphi na iingxaki ezifunyenweyo.

4. Ukukhuselwa kokusingqongileyo: Iingcingo zokuchasana zidla ngokufuna ukusebenza kwindawo eyomileyo, engagqwaliyo yerhasi ukuze kuthintelwe umonakalo kwizinto zocingo ezixhathisayo.

Isishwankathelo, ukubala ngokuchanekileyo umthwalo womphezulu wocingo oluchasayo yinto ebalulekileyo ekuqinisekiseni ukusebenza kwayo okuqhelekileyo kunye nobomi benkonzo. Kwizicelo ezisebenzayo, kuyimfuneko ukukhetha amaxabiso afanelekileyo okuchasa ngokusekelwe kwiimfuno ezithile kunye neendawo ezisingqongileyo, kwaye zibalwe ngokubambisana nemibandela yokhuseleko kunye nezilungiso zeqondo lokushisa. Ngelo xesha, ingqalelo kufuneka ihlawulwe kwiimeko ezilungileyo zokutshatyalaliswa kobushushu, ukuthintela ukugqithiswa, kunye nokuhlolwa rhoqo ukuqinisekisa ukusebenza okuthembekileyo kocingo lokumelana.
