Chipatala chathu chinayambitsa Shimadzu SCT 3000TX CT scanner mu 1989. Dera lachiwiri lapamwamba kwambiri la chipangizochi lili ndi tetrode, ndipo capacitor yapamwamba imagwira ntchito pansi pa njira ya voltage feedback mode. Mu 1995, cathode-side high-voltage capacitor (yotchedwa "C2") inasweka. Chifukwa cha zovuta kupeza zida zosinthira panthawiyo, tinayitanitsa zida zatsopano kwinaku tikutumiza C2 yolakwika ku ntchito yokonza kuti ikonze.

1. Kutsimikizira Kukonzekera ndi Kugwira Ntchito Koyamba kwa Capacitor

• Kukhazikitsa Kokwera: C2 yokonzedwayo inabwezeretsedwanso kumbali ya cathode yoyambirira, pamene capacitor yatsopano inayikidwa pambali ya anode. Pakadali pano, capacitor yoyambirira ya anode (yomwe imatchedwa "C1") idachotsedwa kwakanthawi kuti isungidwe.
• Operation Check: Dera lapamwamba lamagetsi linatsegulidwa, ndipo capacitor imagwira ntchito bwino. Kuyesa kosalekeza kwa masiku 15 kunatsimikizira kukhazikika ndi kudalirika kwa C2.
• Ndondomeko Yantchito Yanthawi yayitali: Pofuna kupititsa patsogolo zipangizo zamakono, C1 inasungidwa pamalo oyenera (ndi kutentha ndi chinyezi), pamene C2 inasunga ntchito yake.

2. Kulepheranso kwa C2 ndi Zovuta Posintha ndi C1

• Zotsatira Zoyezera Zachilendo: Mphamvu yoyezera inali 0.2μF yokha, yotsika kwambiri kuposa mlingo wadzina wa 0.5μF. Izi zikuwonetsa zizindikiro zaukadaulo komanso kusagwira bwino ntchito kwa C1.

3. Mbiri Yakale ya Capacitor ndi Kukonza Njira

3.1 Makhalidwe Ogwira Ntchito ndi Kulephera Kwamachitidwe Kusanthula kwa C1

• Zabwino zodzichiritsa zokha komanso mawonekedwe apamwamba kwambiri okhala ndi voliyumu yayikulu kwambiri ya 125kV.
• Imayang'anira ntchito ziwiri zazikuluzikulu pagawo lamphamvu lamagetsi polarization: kuwongolera ma voltage ndi kusungirako mphamvu.

• "Kusintha kwa thupi" chifukwa cha kusungirako kwa nthawi yaitali: Dielectric (filimu ya polypropylene) mkati mwa capacitor ikhoza kukhala yowonongeka pang'ono panthawi yosungirako nthawi yayitali, kuchititsa kuchepa kwa kanthawi kochepa.
• Zochepera pa zida zoyezera: Muyezo wa ma capacitance metres okhazikika potengera kuyitanitsa/kuthamangitsidwa kwa batire la DC, lomwe limasiyana ndi mphamvu yamagetsi yoyezera komanso momwe zinthu zilili panopa m'mabwalo enieni amphamvu kwambiri, zomwe zingathe kulephera kuwunika bwino momwe C1 ikugwirira ntchito.

4. Njira Yoyatsira Malipiro ndi Zotsatira za C1

4.1 Njira Zoyambira Zida ndi Kuyimitsa

4.2 Kutsimikizira Kwantchito Pambuyo Poyambitsa

• Kufufuza kwa Basic Operation: Kutsimikizika kwa kV komwe kuli koyipa, kuwunika zolakwika za chipangizocho, ndikuchita njira zotenthetsera.
• Kutsimikizira Ubwino wa Zithunzi: Kutsimikizika kwazomwe zikuchitika komanso kuwongolera pogwiritsa ntchito phantom yamadzi. Zotsatira zinawonetsa zithunzi zojambulidwa bwino, zida zokhazikika, komanso palibe kutulutsa kwamphamvu kwambiri kapena phokoso lachilendo.
• Kuwunika kwa Clinical Operation Check: Kujambula kwa CT kwa ziwalo zosiyanasiyana za thupi la odwala kunatsimikizira kuti chipangizocho chikugwira ntchito bwino, ndi khalidwe lachifanizo lomwe limakhalabe lofanana ndi lisanalephereke.

5. Zophunzira pa Nkhaniyi

5.1 Ubwino Wachuma ndi Ntchito

• Kuchepetsa: Ma capacitor okwera kwambiri ndi zigawo zikuluzikulu za CT scanner, ndipo kubweretsa zatsopano kumafuna ndalama zambiri. Mlanduwu udapulumutsa ndalama zambiri pokonzanso zida zomwe zidasokonekera ndikutsegula magawo omwe adasungidwa kwanthawi yayitali.
• Kuchepetsa Kusamalira Nthawi: Ngakhale kugula zinthu zakunja nthawi zambiri kumatenga nthawi yayitali, kukonza ndi kugwiritsanso ntchito zida zomwe zidalipo kale kumachepetsa kuchepa kwa zida ndikuchepetsa kukhudzidwa kwa ntchito zachipatala.

5.2 Malingaliro Aukadaulo

• Kuyambitsa Kuthekera kwa Zida Zosungidwa Kwanthawi yayitali: Ngakhale ma capacitor okwera kwambiri amakumana ndi kuchepetsedwa kwa capacitance chifukwa cha kusungidwa kwa nthawi yayitali, kuyambitsa kwapang'onopang'ono kwapang'onopang'ono pamalo enieni ozungulira nthawi zina kumatha kuwabwezeretsa ku mphamvu zovoteledwa kuti zigwiritsidwe ntchito bwino.
• Kusankha Moyenera Zida Zoyezera: Kuwunika magwiridwe antchito amafunikira malo oyezera pafupi ndi momwe amagwirira ntchito. M'malo mongoweruza kuti zinthu zili bwino potengera zotsatira za mita ya capacitance, m'pofunika kuphatikizira ndi kuyesa kwa magwiridwe antchito m'mabwalo enieni.
