Khasaarooyinka Tijaabada Tooska ah ee Hadda (DC).
(1) Haddii aanay jirin wax awood ah oo ku saabsan shayga la cabbiray, korantada imtixaanku waa in ay ka bilaabataa "eber" oo si tartiib ah u kacdaa si ay uga fogaato dallacaadda xad-dhaafka ah ee hadda.Korontada lagu daray ayaa sidoo kale hooseysa.Marka dallacadu aad u weyn tahay, waxa hubaal ah in ay keeni doonto khalad tijaabiyaha oo natiijada imtixaanka ka dhigi doonta mid khaldan.
(2) Maaddaama ay DC-gu ay tijaabinayso danab ay ku dallaci doonto shayga tijaabada ku jira, tijaabada ka dib, shayga tijaabada ku jira waa in la sii daayo ka hor inta aan loo gudbin tallaabada xigta.
(3) Si ka duwan tijaabada AC, DC-gu waxa lagu tijaabin karaa hal polarity oo keliya.Haddii badeecada la doonayo in lagu isticmaalo korantada AC, khasaaradan waa in la tixgeliyo.Tani sidoo kale waa sababta inta badan xeeriyeyaasha badbaadada ay ku taliyaan isticmaalka AC tijaabada korantada.
(4) Inta lagu guda jiro imtixaanka adkeysiga AC, qiimaha ugu sarreeya ee danabku waa 1.4 jeer qiimaha uu muujiyay mitirka korantada, kaas oo aan lagu muujin karin mitirka korantada ee guud, sidoo kale laguma gaari karo DC-ga tijaabada korantada.Sidaa darteed, xeerarka badbaadada badankood waxay u baahan yihiin in haddii DC-ga la isticmaalo tijaabada korantada, tamarta tijaabada waa in lagu kordhiyaa qiime siman.
Ka dib marka la dhammeeyo tijaabada korantada ee DC-ga, haddii shayga tijaabada ku jira aan la sii dayn, way fududahay in la sameeyo shoog koronto oo ku socda hawlwadeenada;Dhammaan tijaabiyeyaashayada korantada ee DC-ga waxay leeyihiin shaqeyn degdeg ah oo dareere ah oo ah 0.2s.Kadib marka la dhammeeyo tijaabada korantada ee DC, tijaabiyaha Waxa uu si toos ah u soo dayn karaa korontada jidhka la tijaabiyay 0.2s gudahood si loo ilaaliyo badbaadada hawlwadeenka.
Hordhac faa'iidooyinka iyo khasaarooyinka AC u adkaysta tijaabada danabka
Inta lagu jiro tijaabada korantada adkeysiga, tamarta uu isticmaalo tijaabiyaha tamarta adkeysiga jirka jirka la tijaabiyay waxaa loo go'aamiyaa sida soo socota: ku dhufo tamarta shaqada ee jirka la tijaabiyay 2 kuna dar 1000V.Tusaale ahaan korantada shaqada ee shayga la tijaabiyay waa 220V, marka la sameeyo tijaabada korantada adkeysiga, tamarta adkeysigu waa 220V+1000V=1440V, guud ahaan 1500V.
Tijaabada korantada adkeysigu waxa ay u qaybsantaa AC-ga iyo tijaabinta tamarta adkaysiga DC;Faa'iidooyinka iyo khasaarooyinka AC ee tijaabada korantada ee adkeysiga waa sida soo socota:
Faa'iidooyinka AC u adkeysaneyso tijaabada korantada:
(1) Si guud marka loo hadlo, tijaabada AC way fududahay in la aqbalo qaybta badbaadada marka loo eego tijaabada DC.Sababta ugu weyn ayaa ah in badi alaabooyinka ay adeegsadaan alternating current, iyo alternating current test waxa uu tijaabin karaa polarity togan iyo taban ee sheyga isku mar, kaas oo si buuxda ula jaan qaadaya deegaanka badeecada loo isticmaalo oo la jaan qaada. oo leh xaaladda dhabta ah ee isticmaalka.
(2) Maaddaama capacitors-ka qalloocan aan si buuxda loo dallaci karin inta lagu jiro tijaabada AC, laakiin ma jiri doonto wax degdeg ah oo degdeg ah, markaa looma baahna in la oggolaado korantada tijaabada si tartiib tartiib ah, iyo tamarta buuxda ayaa lagu dari karaa bilowga tijaabi, ilaa alaabtu ay xasaasi u tahay korantada galitaanka oo aad xasaasi u ah.
(3) Mar haddii tijaabada AC aanu buuxin karin awoodahaas khaldan, looma baahna in la sii daayo shayga tijaabada ka dib baaritaanka, taas oo ah faa'iido kale.
Faa'iido darrada AC u adkeysaneyso tijaabada korantada:
(1) Khasaaraha ugu weyni waa in haddii awoodda qalloocan ee shayga la cabbiray uu weyn yahay ama shayga la cabbiray uu yahay culeys awood leh, hadda soo baxay wuxuu noqon doonaa mid aad uga weyn kan hadda jira ee daadinta, sidaa darteed hadda qulqulka dhabta ah lama ogaan karo.hadda.
(2) Khasaaro kale ayaa ah in maadaama hadda loo baahan yahay awoodda qalloocan ee shayga la tijaabiyay waa in la keenaa, wax soo saarka hadda ee mishiinka ayaa aad uga weyn kan hadda marka la isticmaalayo tijaabada DC.Tani waxay kordhinaysaa khatarta hawlwadeenka.
Ma jiraa farqi u dhexeeya ogaanshaha arc iyo tijaabada hadda?
1. Ku saabsan isticmaalka shaqada ogaanshaha arc (ARC).
a.Arc waa dhacdo jireed, gaar ahaan koronto garaacis ah oo soo noqnoqda.
b.Xaaladaha wax soo saarka: saamaynta deegaanka, saamaynta habka, saamaynta alaabta.
c.Arc waa mid aad iyo aad uga walaacsan qof walba, sidoo kale waa mid ka mid ah shuruudaha muhiimka ah ee cabbiraadda tayada alaabta.
d.Taxanaha RK99 ee barnaamijka lagu xakameynayo tijaabiyaha adkaysiga korantada ee ay soo saartay shirkadeena ayaa leh shaqada ogaanshaha arc.Waxay muunad ku muujisaa calaamada garaaca garaaca sare ee ka sarreeya 10KHz iyada oo loo marayo shaandhaynta baas sare leh oo leh jawaab celin ka sarraysa 10KHz, ka dibna waxay la barbardhigtaa bartilmaameedka qalabka si loo go'aamiyo in uu u qalmo iyo in kale.Foomka hadda jira waa la dejin karaa, heerka heerka sidoo kale waa la dejin karaa.
e.Sida loo doorto heerka dareenka waa in uu dejiyaa isticmaaluhu iyadoo loo eegayo sifooyinka alaabta iyo shuruudaha.
