Daraasadda Kiis: Dib u Bixiye Awoodda Korontada Sare ee Mashiinka CT

Soo bandhigida isbitaalkeena 1989 sano Shimadzu SCT 3000TX CT mashiinka, tetrode wareegga sare ee tamarta sare
iyo hab jawaab celinta danab capacitor sare capacitor, ilaa 1995 sano dhinaca cathode ee capacitor danab sare (C2, isla hoos) burburay, sababtoo ah ma qaybo beddelka, dalbanaya waqti isku mid ah dhaawac capacitor ah in dayactirka guriga dukaan. Ka dib markii la helo capacitor, capacitors si loo xaqiijiyo tayada waxqabadka dayactirka, oo ku rakibi doona dhinaca cathode ee asalka ah, alaabta cusub ee lagu rakibay dhinaca anode ee capacitor, capacitor asalka ah (C1, Hoos) ayaa la dhigayaa; boot circuit danab sare iyo heerka qalabka capacitance waa caadi, ka dib 15 maalmood oo hawlgal joogto ah, taasoo muujinaysa in C2 deggan oo la isku halayn karo. Si loo kordhiyo waxtarkeeda, waxay kaydin ku habboon tahay C1, C2 si loo ilaaliyo xaaladda shaqada hadda jirta. Bishii Ogosto C2 O1 burburku mar kale, furitaanka alaabada si ay u noqoto beddelka C1, waxa uu ahaa mid aan shaqayn muddo toddoba sano ah, qalabka cabbiraadda awoodda ayaa cabbiraya labada dhibcood ee dhammaadka "T" iyo "N" oo keliya inta u dhaxaysa qiimaha awoodda ilaa O. 2, cf magac ahaan. qiimeynta O. 5 doorbidid cad oo hooseeya, oo soo jeedinaya in tilmaamayaasha farsamada ee C1 aan caadi ahayn, waxqabadka liita. Irbadu waxay isticmaali kartaa awoodda ay ku rakiban tahay, waxaanu samaynay isku day weyn oo xaniinyo ah, ka dib baaritaano badan iyo daaweyn firfircoon ka dib, waxay soo kabsaneysaa dallacaadda caadiga ah iyo bixinta gobolka, oo la geliyey hawlgalka.

1) Xaaladda shaqo ee Capacitor:

Waayo, saliidda ka buuxsamay capacitor sare-voltage metallized film polypropylene duudduuban waxaa lagu sameeyaa is-bogsiin wanaagsan, danab ilaa 125kV; ee wareegga-hoose ee danab sare, laga bilaabo nidaamiyaha. Iyo doorka kaydinta tamarta. In kasta oo Cl uu shaqaynayo muddo dheer, cilladaha aan caadiga ahayn ee qiimaha la qiyaasay, marka loo eego hababka iyo moodooyinka capacitor-ka ee fashilka, waxaan u maleyneynaa in tani ay si fudud uga tarjumayso capacitor-ka naafada muddada dheer ee hoos yimaada xaaladda jireed, iyo qalabka cabbiraadda awoodda qalabka. "

Aaladaha, lagu dhisay DC-ga lacag bateriga ah iyo soosaarida danabteeda la qiimeeyay, tan hadda jirta iyo awooda ma noqon karto wareegga hoose iyo midka-cadaadiska sare. "Gobol marka la barbardhigo aqoonsiga ugu dambeeya ee xooggiisa iyo daciifnimadiisa, waa in la qaato tijaabooyin si loo go'aamiyo.

2) Tallaabooyinka kicinta mashiinka

(1) waxaa lagu rakibi doonaa koronto-dhaliyaha koronto-dhaliyaha sare ee C1side, feylasha boot-ka ee laga soo dejiyo kontaroolada ku-meel-gaarka ah ee kontaroolka, macdan qun-goos goos goos ah, si tartiib tartiib ah u kordhiya tamarta korantada ee habka, xarumaha dib u soo kabashada firfircoon ee dhabta ah, waa in si dhow loogu fiirsadaa halkan waxaa loola jeedaa miiska soo bandhigidda kV, oo lagu dallaco qiimaha hoosaadka, waxaa laga jabin karaa koronto-goynta, Cilmiga waxaa lagu cabiray awoodda, caabbinta korantada, bal in astaamaha la arkay oo la duubay, sidaa darteed horumar joogto ah, oo aan xagjir ahayn;

(2) khidmadda firfircoonida marka qiimaha quwadda tartiib tartiib ah ee 100kV, qiyaasta awoodda la qiyaasay ee C1 ayaa kor u kacday O. 46, marka la soo dallaco 12okV, awoodda C1 waxay ku dhowdahay qiimeynta asalka ah, oo aan lahayn khariidad aan caadi ahayn oo ka hortagga capacitor, ka dibna, waa la damin karaa fiilooyinka kala goynta C1. La cabbiray mar kale qiimaha awoodda go'an ayaa weli ku dhow qiimaha la qiimeeyay; (3) dib-u-xeerka iyo Kor-u-qaadista, marka dhinaca anode ee capacitor C1 lagu dhammeeyo mashiinka CT si loo galo kharashka iyo gobolka diyaarinta, kala qaybin ha hubin kV dheelitirnaanta togan iyo taban, ma jiro mishiinka xiriirka aan caadiga ahayn ka dibna dib u bilow. , Tababarka kululaynta joogtada ah, xajmiga soo-gaadhista hadda ee caadiga ah, jaangooyooyinka biyaha, sawirka la sawiray si sax ah, miiska qalabku wuxuu muujinayaa xasilloon, cadaadis sare iyo buuq aan caadi ahayn. Ka xaaq qaybaha kala duwan ee mashiinka CT scan ee bukaanka si uu si sax ah u shaqeeyo, tayada sawirka sidii hore.

3 waayo aragnimada waanu baranay

(1) capacitor danab sare waa qayb muhiim ah CT, haddii ay waxyeello, hordhaca ah ee beddelka loo baahan yahay, qaali ah, ailure irbado ee sida liidata, is-kicin dayactirka. Kaydinta kharashka, waxay soo gaabinaysaa wareegga dayactirka, faa'iidooyinka dhaqaale iyo bulsho ee muhiimka ah

(2) capacitors koronto-sare muddo dheer guriga, ka dib hoos u dhac ku ah awoodda, weli waxaa lagu dhaqaajin karaa by kharashka si kor loogu qaado awoodda la qiimeeyay, ku soo noqdaan isticmaalka caadiga ah, qalabku waa inuu ciyaaro waxqabadka.

Haddii aad rabto inaad wax badan ka ogaato mashiinka CT-ga ee loo isticmaalo capacitor danab sare, fadlan la xiriir kooxdayada injineerada wixii faahfaahin ah.
