Nooca rasaasta iyo furaha nooca koronta sare ee capacitor dhoobada, sida loo doorto?
AMA
Dad badan oo danab sare capacitors dhoobada oo leh koronto iyo awood isku mid ah waxay leeyihiin laba astaamood oo kala duwan: nooca rasaasta iyo nooca biraha. Marka, waa maxay nooca capacitor danab sare waa in loo isticmaalo habka codsiga, waxaan qaadan 5000PF30KV capacitor dhoobada sida tusaale si loo falanqeeyo.
Tusaale ahaan, macmiilku waxa uu rabaa in uu naqshadeeyo wareegga korantada, kaas oo ka kooban saddex qaybood: Mid waa capacitor sare, mid waa rectifier, ka kalena waa transformer, danab wax soo saarku wuxuu ku xiran yahay capacitor iyo capacitor ayaa ku xiran. tuubada toosiyaha, kaas oo buuxiya shuruudaha dhabta ah.
Ka soo qaad in aad rabto in aad hesho il danab sare 200KV, capacitor 30KV5000PF, kaliya oo ku saabsan 10 taxane. Laga soo bilaabo rakibaadda ee hadalka, hubaal waa capacitor isticmaalaya nooca fur ku haboon. Haddii aad isticmaasho capacitor, u baahan PCB gaar ah oo go'an. Si kastaba ha noqotee, dhamaadka nooca, ma fududa in la isticmaalo, laakiin fiiri xuduudaha dhabta ah. Hadda ma aha guud ahaan koronto dhaliye sare. Qalab badan oo koronto-dhaliyaha sare ee tijaabada ah, hadda jira oo ku saabsan 10MA. qaar ka mid ah qalabka X-ray, CT, hadda waa ilaa 1600MA. Marka guud ahaan marka la hadlo, hadda waa yar yahay. Inta badan alaabada koronto-dhaliyaha sare waxaa loo isticmaalaa jawi dhexdhexaad ah, taas oo ah in la yiraahdo inta jeer ee 10KHZ-60KHZ. Waxaa jira tiro shuruudo ah oo suurtagal ah 100KHZ 200KC, qalabka capacitor wuxuu leeyahay shuruudo gaar ah. Iyada oo koronto sare leh dielectric dhoobada, dhoobada dielectric waa dhaqaale iyo wax ku ool ah waa Y5T, capacitor ee maaddadan ka shaqayn kara in wareegga garaaca wadnaha gudahood 200KHZ.
Marka loo eego Y5T, waxaan kugula talin karnaa isticmaalka walxaha 30KV5000PF. Sababtoo ah hadda waa yar yahay, nooca siliggu wuxuu buuxin karaa shuruudaha. Haddii alaabtu ay sarrayso, hadda waxa uu ka badan yahay 2A, isticmaalka la soo jeediyay ee isticmaalka furaha korantada sare. Doorashada saxda ah ee muhiimka ah waxay ku jirtaa: ma aha oo kaliya buuxinta baahiyaha booska naqshadeynta, laakiin sidoo kale waxay yareyn kartaa kharashka.
