I-Case Study: Buyisela iCapacitor yeCeramic ePhezulu yeVoltage kwi-CT Machine

Ukuqaliswa kwesibhedlele sethu iminyaka ye-1989 ye-Shimadzu SCT 3000TX CT umatshini, i-high voltage high circuit circuit tetrode
kunye nemowudi yempendulo yombane ophezulu we-capacitor, ukuya kwi-1995 iminyaka icala le-cathode ye-capacitor ephezulu yombane (C2, efanayo ngezantsi) ukuphuka, ngenxa yokuba akukho nxalenye yokutshintshwa, uku-odola kwangaxeshanye ukonakalisa i-capacitor kwivenkile yokugcinwa kwekhaya. Emva kokufumana i-capacitor, i-capacitors ukwenzela ukuba kuqinisekiswe umgangatho wokusebenza kokulungisa, kwaye iya kuyifaka kwicala le-cathode ye-original, iimveliso ezintsha ezifakwe kwicala le-anode ye-capacitor, i-original capacitor (C1, Ngezantsi) ibekwe; i-boot high voltage circuit kunye ne-capacitance device status iqhelekile, emva kweentsuku ezili-15 zokusebenza okuqhubekayo, ebonisa ukuba i-C2 izinzileyo kwaye ithembekile. Ukwandisa ukusebenza kwayo, ukugcinwa okufanelekileyo kweC1, iC2 ukugcina imeko yangoku yomsebenzi. Ngo-Agasti C2 O1 ukwaphulwa kwakhona, uluhlu lokuvula ukuba C1 substitution, sele ingasebenzi iminyaka esixhenxe, i-capacitance isixhobo sokulinganisa ukulinganisa amanqaku amabini ekupheleni "T" kunye "N" kuphela phakathi kwexabiso umthamo ukuya ku-O. 2, cf nomineral. ukulinganisa kwe-O. 5 okukhethiweyo okucacileyo okuphantsi, okucebisa ukuba izikhombisi zobugcisa zeC1 ezingaqhelekanga, ukusebenza kakubi. Inaliti inokusebenzisa umthamo wayo ofakiweyo, senze umzamo omkhulu we-bile, emva kovavanyo oluninzi kunye nonyango olusebenzayo, ibuyele kwimeko yokutshaja kunye nokukhupha okuqhelekileyo, yaqala ukusebenza.

1) Imeko yokusebenza yeCapacitor:

Kwi-oyile ezaliswe yi-high-voltage capacitor metallized polypropylene film roll yenziwa ngokuziphilisa kakuhle, i-voltage ukuya kwi-125kV; kwisekethe ye-voltage ephezulu ye-sub-polar, ukusuka kumlawuli. Nendima yokugcina amandla. Nangona i-Cl ingasebenzi ixesha elide, ixabiso elilinganiselweyo elilinganisiweyo, ngokweendlela zokungaphumeleli kwe-capacitor kunye neemodeli, sicinga ukuba oku kubonisa nje i-capacitor ekhubazekile yexesha elide-efana phantsi kombuso womzimba, kunye nesixhobo sokulinganisa amandla kwisixhobo. "

Izixhobo, ezakhelwe-ngaphakathi kwi-DC ibhetri kunye nokukhutshelwa kwamandla ombane alinganisiweyo, okwangoku kunye nomthamo akunakuba yi-sub-polar kunye noxinzelelo oluphezulu lwesekethe. "urhulumente xa kuthelekiswa nokuchongwa kokugqibela kwamandla kunye nobuthathaka bawo, kufuneka yamkelwe kuvavanyo ukumisela.

2) Amanyathelo okuvula umatshini

(1) iya kufakwa kwi-cathode C1side kwi-high-voltage generator cathode, iifayile zokuqala kwi-cabinet control sub-switch control ibhekiselele i-kV yokubheja itrayibhile yokubhatala, ukuhlawula ixabiso le-block-block, ichithwe kwi-wiring ye-capacitor, i-Cl yayinamandla okulinganisa, ukumelana nokusetyana kombane, nokuba ngaba i-anomalies ibonwe kwaye ibhaliwe, ngokunjalo inkqubela phambili, ingagqithisi;

(2) intlawulo yokuvula xa ixabiso lamandla ngokuthe ngcembe le-100kV, ixabiso le-capacitance elilinganisiweyo le-C1 liye lanyuka laya kwi-O. 46, xa itshaja i-12okV, umthamo we-C1 uye waba kufutshane nomlinganiselo wokuqala, kwaye akukho mapping engaqhelekanga ye-anti-capacitor, ngoko, ingacinywa i-C1 yokuqhawula iingcingo. Ilinganiswe kwakhona ixabiso elimiselweyo lomthamo lisekufutshane kwixabiso elilinganisiweyo; (3) i-wiring kwakhona kunye ne-Power-up, xa icala le-anode le-capacitor C1 ligqitywe ngomatshini we-CT ukungena kwintlawulo kunye nombuso wokulungiselela, ulwahlulo ungajongi i-kV elungileyo kunye nebhalansi engalunganga, akukho matshini wobudlelwane obungaqhelekanga kwaye uqalise kwakhona. , ukuqeqeshwa kwesiqhelo sokufudumala, ubungakanani bexesha langoku lokuchayeka kwisiqhelo, ukulinganisa i-phantom yamanzi, umfanekiso oskeniweyo ngokuchanekileyo, itafile yesixhobo ibonisa ukukhutshwa okuzinzile, ukukhutshwa koxinzelelo oluphezulu kunye nengxolo engavamile. Tshayela iindawo ezahlukeneyo zesigulana somatshini wokuskena we-CT ukuze usebenze ngokufanelekileyo, umgangatho womfanekiso njengangaphambili.

3 Amava esiwafundileyo

(1) i-high-voltage capacitor yinxalenye ebalulekileyo ye-CT, ukuba yonakele, ukuqaliswa kokutshintshwa kuyafuneka, ixabiso elibi kakhulu, i-ailure yenaliti yezo zihlwempuzekileyo, zisebenze ngokwakho ukulungiswa. Ukonga ngeendleko, mfutshane umjikelo wolondolozo, iinzuzo zoqoqosho nezentlalo Okubalulekileyo

(2) i-high-voltage capacitors ixesha elide ekhaya, emva kokuhla kwamandla, isenokuthi isebenze ngentlawulo yokuphucula umthamo olinganisiweyo, ubuyele ekusebenziseni okuqhelekileyo, isixhobo kufuneka sidlale ukusebenza.

Ufuna ukwazi ngakumbi malunga nomatshini we-CT osetyenzisiweyo kwi-capacitor yombane ophezulu, nceda u tyelele uqhagamshelane neqela lethu leenjineli ngeenkcukacha.
