I-Case Study: Buyisela i-High Voltage Ceramic Capacitor kumshini we-CT

Ukwethulwa kwesibhedlela sethu iminyaka engu-1989 umshini we-Shimadzu SCT 3000TX CT, i-high voltage secondary circuit tetrode
kanye nemodi yempendulo ye-voltage ephezulu ye-voltage capacitor, kuya eminyakeni engu-1995 uhlangothi lwe-cathode lwe-high voltage capacitor (C2, okufanayo ngezansi) ukuwohloka, ngoba azikho izingxenye ezishintshwayo, eziyala ngesikhathi esifanayo ukulimaza i-capacitor ekugcinweni kwekhaya lesitolo. Ngemuva kokuthola i-capacitor, ama-capacitor ukuze kuqinisekiswe ikhwalithi yokusebenza kokulungisa, futhi izoyifaka ohlangothini lwe-cathode lwangempela, imikhiqizo emisha efakwe ohlangothini lwe-anode lwe-capacitor, i-capacitor yasekuqaleni (C1, Ngezansi) ibekwe; I-boot high voltage circuit kanye nesimo sedivayisi ye-capacitance sivamile, ngemva kwezinsuku ezingu-15 zokusebenza okuqhubekayo, okubonisa ukuthi i-C2 izinzile futhi inokwethenjelwa. Ukuze kukhuliswe ukusebenza kwayo kahle, igcina kahle i-C1, C2 ukuze kugcinwe isimo samanje somsebenzi. Ngo-Agasti ukuhlukaniswa kwe-C2 O1 futhi, i-inventory evulayo ukuze ithathelwe indawo ye-C1, ibingasebenzi iminyaka eyisikhombisa, idivayisi yokulinganisa amandla ikala amaphuzu amabili okugcina ka-"T" kanye "no-"N" kuphela phakathi kwevelu yomthamo ukuya ku-O. 2, cf ngokulinganisa. isilinganiso se-O. 5 esicacile sokuncamelayo kokuphansi, okuphakamisa ukuthi izinkomba zobuchwepheshe ze-C1 ezingavamile, ukusebenza kabi. Inaliti ingasebenzisa umthamo wayo ofakiwe, senze umzamo omkhulu we-bile, ngemuva kokuhlolwa okuningi kanye nokwelashwa okusebenzayo, ilulama esimweni esijwayelekile sokushaja nokukhipha, iqale ukusebenza.

1) Isimo sokusebenza se-Capacitor:

Ukuze ogcwele uwoyela high-voltage capacitor metallized polypropylene ifilimu roll yenziwe ngokuziphilisa okuhle, voltage kufika ku-125kV; kumjikelezo we-voltage ephezulu ye-sub-polar, kusukela kusilawuli. Nendima yokugcina amandla. Nakuba i-Cl ingenzi lutho isikhathi eside, okungavamile kwenani elilinganiselwe, ngokuya ngezinqubo namamodeli okuhluleka kwe-capacitor, sicabanga ukuthi lokhu kuvele kubonise i-capacitor ekhubazekile yesikhathi eside ngaphansi kwesimo somzimba, kanye nedivayisi yokulinganisa amandla ethuluzi. "

Amadivayisi, okwakhelwe ngaphakathi ku-DC ukushaja kwebhethri nokukhishwa kwamandla kagesi alinganisiwe, amanje namandla akakwazi ukuba yisifunda esiphansi se-polar nesokucindezela okukhulu. "izwe uma liqhathaniswa nokuhlonza kokugcina amandla nobuthakathaka balo, kufanele lisetshenziselwe ukuhlolwa ukuze kutholakale.

2) Izinyathelo zokuvula umshini

(I-1) izofakwa ku-high-voltage generator cathode C1side, the boot boot from the control cabinet sub-switch control, izimayini nge-intermittent, kancane kancane zikhuphula umthamo wokushaja wendlela, izisetshenziswa ezisebenzayo zokutakula, kufanele zibhekwe lapha I-KV ishaja itafula lokukhokhisa, ukushaja inani le-sub-block, lingahle liphulwe ku-capacitor wiring, Cl belinganiselwa umthamo, ukumelana kokufakwa kukagesi, noma ngabe ukungaboni ngaso linye kugcinwe futhi kwaqoshwa, inqubekela phambili eqhubekayo, hhayi enkulu;

(2) ishaja yokuvula lapho inani lamandla kancane kancane elingu-100kV, inani lamandla elilinganisiwe C1 lenyukele ku-O. 46, lapho ishaja i-12okV, umthamo we-C1 usondelene nesilinganiso sangempela, futhi akukho ukumepha okungajwayelekile kwe-anti-capacitor, bese-ke, ingacishwa C1 nqamula izintambo. Kukalwe futhi inani lomthamo ongashintshi liseseduze nenani elilinganiselwe; (3) ukuhlanganisa kabusha izintambo kanye nokuphakamisa amandla, lapho uhlangothi lwe-anode lwe-capacitor C1 luqediwe ngomshini we-CT ukuze lungene eshajelweni kanye nesimo sokulungiselela, ihlukaniswe ungahloli ibhalansi ye-kV enhle nengalungile, akukho mshini wobudlelwane obungavamile bese uqala kabusha. , ukuqeqeshwa kokufudumala okujwayelekile, usayizi wokuchayeka kwamanje kokujwayelekile, i-phantom yamanzi yokulinganisa, isithombe esiskeniwe ngendlela efanele, ithebula lezinsimbi libonisa ukukhishwa okuzinzile, okunomfutho ophezulu kanye nomsindo ongavamile. Shanela izingxenye ezihlukahlukene zomshini we-CT scan wesiguli ukuze usebenze kahle, ikhwalithi yesithombe njengangaphambili.

3 Okuhlangenwe nakho esikufundile

(1) i-high-voltage capacitor iyingxenye ebalulekile ye-CT, uma yonakele, ukwethulwa kokushintshwa kuyadingeka, ezibizayo, ukufakwa kwezinaliti zalabo abampofu, zisebenze ngokwakho ukulungisa. Ukonga ngezindleko, kufinyeze umjikelezo wesondlo, izinzuzo zezomnotho nezenhlalakahle Okubalulekile

(2) ama-capacitor aphezulu-voltage isikhathi eside ekhaya, ngemva kokuncipha komthamo, asengasebenza ngokushaja ukuze athuthukele kumthamo olinganiselwe, abuyele ekusetshenzisweni okujwayelekile, idivayisi kufanele idlale ukusebenza.

Ufuna ukwazi okwengeziwe mayelana nomshini we-CT osetshenziswe i-high voltage capacitor, sicela uvakashele ukuthintana nethimba lethu lonjiniyela ukuze uthole imininingwane.
