Izinto ezingeloncedo ngoVavanyo oluNgqo ngoku (DC).
(1) Ngaphandle kokuba akukho capacitance kwinto elinganisiweyo, amandla ombane ovavanyo kufuneka aqale “ku-zero” kwaye anyuke kancinci ukunqanda umsinga wokutshaja ngokugqithisileyo.I-voltage eyongeziweyo nayo iphantsi.Xa umjelo wokutshaja ukhulu kakhulu, ngokuqinisekileyo uya kubangela ukugwetywa kakubi ngumvavanyi kwaye wenze umphumo wovavanyo awuchanekanga.
(2) Ekubeni i-DC yokumelana novavanyo lwe-voltage iya kuhlawulisa into phantsi kovavanyo, emva kovavanyo, into ephantsi kovavanyo kufuneka ikhutshwe ngaphambi kokuba iqhubele phambili kwisinyathelo esilandelayo.
(3) Ngokungafaniyo novavanyo lwe-AC, i-DC yokumelana novavanyo lombane inokuvavanywa kuphela nge-polarity enye.Ukuba imveliso iza kusetyenziswa phantsi kombane we-AC, oku kungalunganga kufuneka kuthathelwe ingqalelo.Esi sisizathu sokuba kutheni uninzi lwabalawuli bezokhuseleko bencoma ukusebenzisa i-AC yokumelana novavanyo lombane.
(4) Ngexesha lovavanyo lwe-AC lokumelana ne-voltage, ixabiso eliphakamileyo le-voltage li-1.4 kumaxesha exabiso eliboniswe imitha yombane, engenakho ukuboniswa imitha yombane jikelele, kwaye ayinakufezekiswa yi-DC yokumelana novavanyo lombane.Ngoko ke, imimiselo emininzi yokhuseleko ifuna ukuba ukuba i-DC yokumelana novavanyo lwe-voltage isetyenzisiweyo, i-voltage yokuvavanya kufuneka inyuswe kwixabiso elilinganayo.
Emva kokuba uvavanyo lwe-DC ukumelana nombane lugqityiwe, ukuba into ephantsi kovavanyo ayikhutshwa, kulula ukubangela ukutshitshiswa kombane kumqhubi;zonke ii-DC zethu zokumelana ne-voltage testers zinomsebenzi wokukhupha ngokukhawuleza we-0.2s.Emva kokuba uvavanyo lwe-DC ukumelana nombane lugqityiwe, umvavanyi Uyakwazi ukukhupha umbane ngokuzenzekelayo kumzimba ovavanyiweyo ngaphakathi kwe-0.2s ukukhusela ukhuseleko lomsebenzisi.
Intshayelelo kwiinzuzo kunye nokungalunganga kwe-AC ukumelana novavanyo lombane
Ngexesha lovavanyo lokumelana ne-voltage, i-voltage esetyenziswa ngumvavanyi wokumelana ne-voltage kumzimba ovavanyiweyo igqitywe ngolu hlobo lulandelayo: phinda-phinda i-voltage yokusebenza komzimba ovavanyiweyo nge-2 kwaye wongeze i-1000V.Ngokomzekelo, i-voltage esebenzayo yento evavanyiweyo yi-220V, xa uvavanyo lokumelana nombane lwenziwa, i-voltage ye-voltage tester tester yi-220V + 1000V = 1440V, ngokubanzi i-1500V.
Uvavanyo lokumelana nombane lwahlulahlulwe lwaba luvavanyo lwe-AC lokumelana nombane kunye ne-DC yokumelana novavanyo lombane;Uncedo kunye nokungalunganga kovavanyo lwe-AC lokumelana nombane zezi zilandelayo:
Izinto eziluncedo ze-AC ukumelana novavanyo lombane:
(1) Ngokuqhelekileyo, uvavanyo lwe-AC lulula ukuba lwamkelwe yiyunithi yokhuseleko kunovavanyo lwe-DC.Esona sizathu siphambili kukuba uninzi lweemveliso zisebenzisa i-alternating current, kwaye uvavanyo lwangoku olutshintshayo lunokuvavanya i-polarity entle nengalunganga yemveliso ngaxeshanye, ehambelana ngokupheleleyo nokusingqongileyo apho imveliso isetyenziswa kwaye ihambelana nomgca. kunye neyona meko yokusetyenziswa.
(2) Ekubeni i-capacitors elahlekileyo ayinakuhlawuliswa ngokupheleleyo ngexesha lovavanyo lwe-AC, kodwa akuyi kubakho inrush yangoku ngokukhawuleza, ngoko akukho mfuneko yokuvumela umbane wokuvavanya unyuke kancinci, kwaye umbane opheleleyo unokongezwa ekuqaleni uvavanyo, ngaphandle kokuba imveliso inovakalelo kwi-inrush voltage kakhulu.
(3) Ekubeni uvavanyo lwe-AC alukwazi ukuzalisa loo mandla alahlekileyo, akukho mfuneko yokukhupha into yokuvavanya emva kovavanyo, enye inzuzo.
Izinto ezingeloncedo kwi-AC ukumelana novavanyo lombane:
(1) Eyona nto ingathandekiyo kukuba ukuba i-capacitance elahlekileyo yento elinganisiweyo inkulu okanye into elinganisiweyo ngumthwalo we-capacitive, umbane owenziweyo uya kuba mkhulu kunokoqobo lokuvuza kwangoku, ngoko ke ukuvuza kwangoku akunakukwaziwa.yangoku.
(2) Enye into engalunganga kukuba ekubeni i-current ifunwa yi-capacitance elahlekileyo yento evavanyiweyo kufuneka inikezelwe, imveliso yangoku ngomatshini iya kuba nkulu kakhulu kunomjelo xa usebenzisa uvavanyo lwe-DC.Oku kwandisa umngcipheko kumsebenzisi.
Ngaba kukho umahluko phakathi kokufunyanwa kwe-arc kunye novavanyo lwangoku?
1. Malunga nokusetyenziswa komsebenzi wokufumanisa i-arc (ARC).
a.I-Arc yinto ebonakalayo, ngokukodwa i-high-frequency pulsed voltage.
b.Iimeko zokuvelisa: impembelelo yokusingqongileyo, impembelelo yenkqubo, impembelelo yezinto eziphathekayo.
c.I-Arc ixhalaba ngakumbi nangakumbi ngumntu wonke, kwaye ikwayenye yeemeko ezibalulekileyo zokulinganisa umgangatho wemveliso.
d.Inkqubo ye-RK99 elawulwa yinkqubo yokumelana ne-voltage tester eveliswe yinkampani yethu inomsebenzi wokufumanisa i-arc.Isampula isibonakaliso se-high-frequency pulse ngaphezulu kwe-10KHz ngokusebenzisa isihluzo sokupasa okuphezulu kunye nokuphendula rhoqo ngaphezu kwe-10KHz, kwaye emva koko ithelekise kunye nebhentshi yesixhobo ukugqiba ukuba ifanelekile.Ifom yangoku inokumiselwa, kwaye ifom yezinga nayo ingamiselwa.
e.Indlela yokukhetha inqanaba lovakalelo kufuneka libekwe ngumsebenzisi ngokweempawu zemveliso kunye neemfuno.
