Uhlobo lomthofu kanye nohlobo lwesikulufa oluphezulu lwe-ceramic capacitor, ungakhetha kanjani?
NOMA?
Abaningi voltage okusezingeni capacitors Ceramic nge-voltage efanayo namandla anezici ezimbili ezihlukene: uhlobo lomthofu kanye nohlobo lwesikulufu. Ngakho-ke, hlobo luni lwe-voltage capacitor ephezulu okufanele isetshenziswe kunqubo yokufaka isicelo, sithatha i-5000PF30KV i-ceramic capacitor njengesibonelo sokuhlaziya.
Isibonelo, ikhasimende lifuna ukuklama isekethe ye-voltage yamandla, eyakhiwe izingxenye ezintathu: eyodwa i-high voltage capacitor, enye i-rectifier, enye i-transformer, i-voltage ephumayo ixhunywe ne-capacitor futhi i-capacitor ixhunywe nayo. ishubhu lokulungisa, elihlangabezana nezidingo zangempela.
Ake sithi ufuna ukuthola umthombo wamandla kagesi aphezulu ongu-200KV, i-capacitor 30KV5000PF, cishe uchungechunge oluyi-10 kuphela. Kusukela ekufakweni kokukhuluma, ngokuqinisekile i-capacitor esebenzisa uhlobo lwesikulufa olulula kakhulu. Uma usebenzisa i-capacitor, udinga i-PCB ekhethekile elungisiwe. Nokho, ekugcineni hlobo luni, akulula ukuyisebenzisa kulungile, kodwa bheka imingcele langempela. I-current akuyona ijeneretha kagesi ephezulu. Abaningi high voltage generator test ithuluzi, zamanje mayelana 10MA. amanye amadivaysi e-X-RAY, i-CT, yamanje imayelana ne-1600MA. Ngakho-ke, ngokuvamile, i-current incane kakhulu. Iningi lemikhiqizo ye-high voltage generator isetshenziswa endaweni ephakathi nendawo, okusho ukuthi imvamisa ka-10KHZ-60KHZ. kunezidingo eziningi ezingaba khona ku-100KHZ 200KC, impahla ye-capacitor inezidingo ezithile. Ngenkathi i-dielectric ye-ceramic yamandla aphezulu kagesi, i-dielectric ceramic iyonga futhi iyasebenza i-Y5T, I-capacitor yale nto ingasebenza kumjikelezo we-pulse ngaphakathi kwe-200KHZ.
Ngokusho kwe-Y5T, singancoma ukusetshenziswa kwempahla engu-30KV5000PF. Ngenxa yokuthi i-current incane, uhlobo locingo lungahlangabezana nezidingo. Uma umkhiqizo uphezulu, okwamanje idlula 2A, ukusetshenziswa okuhlongozwayo kohlobo lwesikulufu i-high-voltage capacitor. Ukukhetha okulungile kokubaluleka kulele: hhayi nje ukuhlangabezana nezidingo zendawo yokuklama, kodwa futhi kunganciphisa izindleko.
