Faa'iido darrooyinka Tooska ah ee Tooska ah (DC) imtixaanka
(1) Haddii aysan jirin wax shuruud ah oo aan la qiyaasi karin shayga la cabiray, korantada tijaabada ah waa inay ka bilowdaa "eber" oo si tartiib ah kor ugu kac si looga fogaado in aad ku dallacdo xad dhaafka ah ee hadda jirta. Korantada lagu daro ayaa sidoo kale hooseeya. Marka khidmadda hadda jirta ay aad u weyn tahay, waxay xaqiiqdi u horseedi doontaa si khaldan ee baaritaanka uu u yeesho tijaabada baarista oo ay natiijada baaritaanka ku khaldamaan.
(2) Maaddaama DC-da ay u adkeysay tijaabada korantada inay ku dallaci doonto shayga hoostiisa, baaritaanka ka dib, sheyga hoostiisa waa in laga soo saaraa ka hor intaadan u dhaqaaqin tallaabada xigta.
(3) Si ka duwan imtixaanka AC, DC waxay u adkeysaa imtixaanka korantada lagu tijaabin karo oo keliya hal faallo. Haddii badeecada loo isticmaalo korantada AC, muddadan dartiis waa in la qaddariyo. Tani sidoo kale waa sababta ugu badan ee tilmaamayaasha badbaadada badankood ay kugula talinayaan in la adeegsanayo AC-da si aad u adkeysato imtixaanka korantada.
(4) Inta lagu gudajiro AC-da ayaa u adkeysiga imtixaanka korantada, qiimaha ugu sarreeya ee korantada waa 1.4 jeer qiimaha uu soo bandhigay mitirka korontada, oo aan sidoo kale lagu gaari karin DC-da DC-da ee aan loo adkeysan karin imtixaanka korantada. Sidaa daraadeed, inta badan xeerarka badbaadada badankood waxay u baahan yihiin haddii DC-da ee ay u istcimaalaan imtixaanka korantada la isticmaalo, korantada tijaabada ah waa in lagu kordhiyaa isku qiimo.
Ka dib markii DC ay u adkeyso tijaabada korantada la dhammeystirey, haddii sheyga hoos yimaad ee aan la siinin, way fududahay in shoogga korka lagu shido wadaha. Dhamaan DC-da noola soo horjeeso idaacadaha korantada leh waxay leeyihiin howlo deg deg ah oo ah 0.2s. Ka dib markii DC ay u adkeyso tijaabada korantada la dhammeystirayo, tijaabadu waxay si otomaatig ah u siidaayaa korantada jirka la tijaabiyey 0.2s si loo ilaaliyo badbaadada hawl wadeenka.
Hordhac Faa'iidooyinka iyo faa'iido darrooyinka AC ee u adkeysiga imtixaanka korantada
Intii lagu gudajiray tijaabada korantada, korantada ay codsadeen ka hortagga korantada jidhka korantada ee jirka la tijaabiyey waxaa lagu dhuftaa sida soo socota: Ku dhufo korantada ka shaqeynta jirka oo 2 jir ah oo ku dar 1000v. Tusaale ahaan, korantada shaashadda ee sheyga la tijaabiyey waa 220V, marka ay u adkeysaneyso tijaabada korantada,-ka-u-adkeysiga korantada tijaabada korantada waa 220v + 1000v = 1440v, guud ahaan 1500V.
The-ka ayaa u adkeysi u leh tijaabada korantada ah inay u qaybsantahay AC u adkeyso imtixaanka korantada iyo DC u adkeysiga imtixaanka korantada; Faa'iidooyinka iyo faa'iido darrooyinka AC ee u adkeysiga imtixaanka korantada waa sida soo socota:
Faa'iidooyinka AC ayaa ka hortagaya tijaabada korantada:
(1) guud ahaan hadalka, tijaabada AC waa sahlan tahay in laga aqbalo unugyada badbaadada marka loo eego baaritaanka DC. Sababta ugu weyni waa in inta badan alaabada ay adeegsadaan sida caadiga ah, iyo habka kale ee baaritaanka hadda jira waxay tijaabin kartaa huurka wanaagsan iyo taban ee sheyga isla waqtigaas, kaas oo gebi ahaanba la jaan qaadaya bey'adda ay tahay sheygaas oo leh xaaladda isticmaalka dhabta ah.
(2) Maaddaama maadaama ay si xun loo eedayn karo si buuxda marka loo eego imtixaanka AC, laakiin ma jiri doono injirta injirta ah, marka looma baahna in korantada tijaabada u kordhayo si tartiib tartiib ah, oo korantada oo dhan lagu dari karo bilowga Tijaabada, ilaa sheygu xasaasi u yahay korantada ku lugta leh mid xasaasi ah.
(3) Maaddaama Imtixaanka AC uusan buuxin karin awoodahaas qalafsan, looma baahna in la qaado shayga tijaabada baaritaanka ka dib, taas oo ah faa iido kale.
Faa'iido darrooyinka AC oo ka hortagaya tijaabada korantada:
(1) Faa'iido darrooyinka ugu weyn ayaa ah haddii awoodda dhufatada ah ee shayga la cabiray uu yahay mid weyn ama shayga la cabiray, in la soo saaro in ay aad uga balaaran tahay baxsiga hadda jirta, sidaa darteed daadinta dhabta ah ee hadda lama ogaan karo. Hadda.
(2) Faa'iido kale ayaa ah tan iyo markii hada loo baahan yahay ee uu u baahnaa dhuxusha dhumucda ee shayga la tijaabiyey waa in la siiyaa, soosaarka hadda ah ee mashiinka ayaa aad uga balaaran doonaa kan hadda jira marka la isticmaalo baaritaanka DC. Tani waxay kordhineysaa halista howl wadeenka.
Ma waxaa jira farqi u dhexeeya ogaanshaha Arc iyo imtixaanka hadda jira?
1. Ku saabsan isticmaalka shaqada ogaanshaha Arc (Arc).
a. Arc waa ifafaale jir ahaaneed, gaar ahaan mid soo noqnoqota korantada.
b. Shuruudaha wax soo saarka: Saamaynta deegaanka, saameynta geedi socodka, saameynta qalabka.
c. Arc waa mid aad u badan oo aad uga walaacsan qof walba, sidoo kale waa mid ka mid ah xaaladaha muhiimka ah ee lagu cabiro tayada wax soo saarka.
d. Barnaamijka taxanaha ah ee RK99 ee ay gacanta ku dhigto tijaabada korantada ee ay soo saartay shirkaddayada ayaa leh howsha ogaanshaha CRC. It samples the high-frequency pulse signal above 10KHz through a high-pass filter with a frequency response above 10KHz, and then compares it with the instrument benchmark to determine whether it is qualified. Foomka hadda jira waa la dejin karaa, qaabka heerkana sidoo kale waa la dejin karaa.
e. Sida loo doorto heerka xasaasiga ah waa inuu u dejiyaa isticmaalaha iyadoo loo eegayo astaamaha badeecada iyo shuruudaha.
