Qinisa uvavanyo lwe-voltage kunye novavanyo lokunganyangeki

1, Umgaqo wovavanyo:

a) Ukuvavanywa kwe-voltage:

Umgaqo osisiseko wokuSebenza: Thelekisa ukuvuza okuthe kratya eveliswe sisixhobo esivavanyiweyo kwi-Vightage ephezulu yokuphuma kwe-voltage ngomgwebo omiselweyo ngokusemthethweni. Ukuba ukuvuza okufunyenwe kungaphantsi kunexabiso elisemva, isixhobo sidlulisela uvavanyo. Xa ukuvuselelwa okufunyanwa ngoku kuyinto enkulu kunoxanduva lokugweba, kuthunyelwe i-voltage yovavanyo kwaye i-alamu evakalayo neyembonakalo ithunyelwe, ukuze ichonge i-voltage inamandla anokuvavanywa.

Kumgaqo wovavanyo lokuqala lwesekethe,

I-voltage i-tister ye-tester iqulunqwe ikakhulu yi-AC (ngqo) yoNcedo lweVollage, iMqulu yoLawulo lwexesha, isiseko sexesha, isikhombisi sesekelo. Umgaqo osisiseko wokuSebenza ngu: Umyinge wokuvuza ngokuveliswa oveliswe sisixhobo esivavanyiweyo kwimveliso yevolthi ephezulu ye-voltage yi-test titer ithelekiswa nomgwebo omiselweyo. Ukuba ukuvuza okufumanekayo kungaphantsi kwexabiso leseti, isixhobo sidlulisela uvavanyo, xa kufunyenwe i-leakued ngoku, i-voltage yovavanyo inqunyulwa kwaye ikhutshiwe kwaye i-alam evakalayo ithunyelwe ukufumanisa ivolthi banyamezele amandla enxalenye yokuvavanywa.

b) Ukunyanzeliswa kwentolo:

Siyazi ukuba i-voltage yovavanyo lokuvavanywa kokufakelwa i-Treaser i-500v okanye i-1000V, elingana nokuvavanya i-DC iphinde ihlolwe i-DC. Ngaphantsi kwalo mnikelo wevolthi, isixhobo silinganisa ixabiso langoku, kwaye sikhulise okwangoku ngobalo lwesekethe lwangaphakathi. Okokugqibela, idlula uMthetho we-OHM: R = U / I, iphi i-500v okanye i-1000v ihlolwe, kwaye ndingumvundla okwangoku kule voltage. Ngokweevolthi zovavanyo lwe-voltage, singaziqonda ukuba okwangoku incinci kakhulu, ngokubanzi ingaphantsi kwe-1 μ a.

Ingabonwa koku kungasentla ukuba umgaqo wovavanyo oluyimfuneko lokufakelwa lufana noko kuvavanywa kwe-voltage, kodwa yenye kuphela intetho yomthetho we-OHM. Ukuvuza okwangoku kusetyenziswa ukuchaza intsebenzo yokufakelwa kwento ephantsi kovavanyo, ngelixa i-inshonted inyanzelekile kukuchasa.

2, injongo ye-voltage yovavanyo:

Uvavanyo lwevolthi yovavanyo luvavanyo olungelulo oluqhelekileyo, olusetyenziselwa ukufumana ukuba umthamo weemveliso zemveliso ufanelekile phantsi kombane ophezulu wethutyana. Isebenza nge-voltage ephezulu kwizixhobo ezivavanyiweyo kangangexesha elithile ukuqinisekisa ukuba imisebenzi yokusebenza kwezixhobo yomelele ngokwaneleyo. Esinye isizathu solu vavanyo kukuba inokukhangela ezinye iziphene zesixhobo, ezinje ngomgama ongonelanga kunye nokungabikho kombane kwenkqubo yokwenziwa kwemveliso.

I-3, i-voltage tost kwaye i-voltage yovavanyo:

Kukho umthetho ngokubanzi wevolthi yovavanyo = Umbane wokuhambisa amandla × 2 + 1000v.

Umzekelo: Ukuba amandla ombane anikezela ngemveliso yovavanyo yi-220v, i-voltage yovavanyo = 220v × 2 + 1000v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v = 1480v.

Ngokubanzi, ixesha lokuvavanywa kwe-voltage ye-voltages ngumzuzu omnye. Ngenxa yenani elikhulu leemvavanyo zokunganyangeki kumbane, ixesha lovavanyo lihlala lincitshiswa kwimizuzwana embalwa. Kukho umgaqo oqhelekileyo obonakalayo. Xa ixesha lovavanyo lincitshiswa ukuya kwimizuzwana emi-1-2 kuphela, i-voltage yovavanyo kufuneka inyuswe nge-10 ukuya kwi-20%, ukuze kuqinisekiswe ukuthembeka kokufakwa kuvavanyo lwexeshana.

4, i-alamu yangoku

Ukuseta kwe-alam okwangoku kuya kumiselwa ngokweemveliso ezahlukeneyo. Eyona ndlela ilungileyo kukwenza ukuvuza ngokuvuza iisampulu zangaphambili, fumana ixabiso eliphakathi, kwaye emva koko ubone ixabiso elingaphezulu kwexabiso eliphakathi. Ngenxa yokuba ukuvuza kwe-leakyishini yesixhobo esivavanyiweyo kuyadingeka, kuyafuneka ukuba i-alam yeseti yangoku inkulu ngokwaneleyo ukuba inqande ukubangelwa yimpazamo yangoku, kwaye kufanele ibe mncinci ngokwaneleyo ukunqanda isampulu yesampulu. Ngamanye amaxesha, kunokwenzeka ukufumanisa ukuba isampulu inxibelelana nesiphelo semiphumo ye-voltage tester ngokuseta i-alarm ebizwa ngokuba yi-alarm ebizwa ngokuba yi-alarm ebizwa ngokuba yi-alarm ebizwa ngokuba yi-alarm ebiweyo.

I-5, ukukhetha uvavanyo lwe-AC kunye ne-DC

Uvavanyo lovavanyo, uninzi lwemigangatho yokhuseleko ivumela ukusetyenziswa kwe-AC ye-AC okanye i-DC kuvavanyo lwe-voltage. Ukuba kusetyenziswa ivolumu yovavanyo lwe-AC, xa kufikelelwe kwi-voltage ye-peak, i-insulator ukuba ihlolwe iya kuthwala uxinzelelo oluphezulu xa ixabiso le-Peak lilungile okanye lingalunganga. Ke ngoko, ukuba kugqitywe ukuba ukhethe ukusebenzisa uvavanyo lwe-DC Vinage, kunyanzelekile ukuba kuqinisekiswe ukuba i-DC yovavanyo lwe-DC iphindwe kabini kwi-Actage yoVavanyo loVavanyo lwe-AC, ukuze i-DC Voltage inokulingana nexabiso le-cap. Umzekelo: I-voltage ye-AC ye-DC, ye-DC ye-DC ukuvelisa inani elilinganayo loxinzelelo lombane kufuneka ibe li-1500 × 1.414 yi-2121V DC voltage.

Enye yeenzuzo zokusebenzisa i-DC Voltage yovavanyo lwe-DC kukuba kwimodi ye-DC, ukugela okwangoku nge-alam yokulinganisa i-tempoge ye-tetage yimbonakalo yangoku. Elinye ingenelo lokusebenzisa uvavanyo lwe-DC kukuba i-voltage inokusetyenziswa ngokuthe ngcembe. Xa i-voltage yonyuka, umqhubi unokufumana ukuqukuqela okwangoku ngesampulu ngaphambi kokuqhekeka kwenzeka. Kubalulekile ukuba uqaphele ukuba xa usebenzisa i-DC voltage Gostage ye-DC, isampulu kufuneka ikhutshwe emva kokuba uvavanyo lugqityiwe ngenxa yokutshaja kwecawa kwisekethe. Ngapha koko, nokuba i-voltage ingakanani i-voltage kwaye iphawuleka kangakanani iimpawu zemveliso, kulungile ukukhululwa ngaphambi kokusebenza imveliso.

Ukungancedi kakuhle kuvavanyo lwe-DC ye-DC yeyokuba inokusebenzisa i-voltage yovavanyo kwicala elinye, kwaye ayinakukwazi ukusebenzisa uxinzelelo lombane kwi-polading ezimbini njengovavanyo lwe-ACT, kwaye uninzi lweemveliso ze-elektroniki phantsi koncedo lwamandla e-AC. Ukongeza, kuba i-DC yovavanyo lwe-DC kunzima ukuvelisa, iindleko zovavanyo lwe-DC ziphezulu kunelo kuvavanyo lwe-AC.

Inzuzo yovavanyo lwevolthi ye-AC yeyokuba ikwazi ukubona yonke i-voltage, esondeleyo kwimeko efanelekileyo. Ukongeza, ngenxa yokuba i-voltage ye-AC ayiyi kuhlawulisa amandla, kwiimeko ezininzi, ixabiso langoku elizinzileyo linokufunyanwa ngokuthe ngqo ngokukhupha i-voltage ehambelanayo ngaphandle kwenqanaba lokuphumelela. Ngapha koko, emva kokuba kugqityiwe uvavanyo lwe-AC, akukho sampuli yokukhutshwa iyafuneka.

Ukunqongophala kovavanyo lwevolthi ye-AC kukuba ukuba kukho amandla amakhulu e-Y ephantsi kovavanyo, kwezinye iimeko, uvavanyo lwe-AC luya kuphathwa kakubi. Uninzi lwemigangatho yokhuseleko ivumela abasebenzisi ukuba bangabi nakuqhagamshela amandla e-capacitors ngaphambi kovavanyo, okanye endaweni yoko basebenzise iimvavanyo ze-DC. Xa uvavanyo lwe-DC Vowstage yovavanyo lwenyukayo luye lwanda kwi-YAYITITINE, ayiyi kuba gwenxa kuba amandla angavumeli nakuphi na ukudlula ngeli xesha.
