(1) Muchiitiko chekudzima kwemagetsi, 'tarisa, kunhuwa, bvunza, kuyera'

Tarisa: Vhura goko remagetsi emagetsi, tarisa kana fuse yakavhuvhuta, uye woona mamiriro emukati emagetsi.Kana paine nzvimbo dzakapiswa kana zvikamu zvakaputsika paPCB board yemagetsi emagetsi, chinotariswa chinofanira kunge chiri chekutarisa zvikamu uye zvine chekuita nedunhu redunhu pano.

Kunhuwa: Kunhuwa kana pane kunhuhwirira kunopisa mukati memagetsi uye tarisa kana pane zvakatsva zvikamu.

Mubvunzo: Ndingabvunze nezve maitiro ekukuvara kwemagetsi uye kana pane zvisiri pamutemo mashandiro akaitwa pamagetsi.

Chiyero: Usati wabatidza, shandisa multimeter kuyera voltage kumagumo ese e-high-voltage capacitor.Kana kukanganisa kunokonzerwa nekukundikana kwesimba re LED kuratidza skrini kana dunhu rakavhurika rekushandura chubhu, kazhinji, voltage kumagumo maviri e-high-voltage filtering capacitor haina kubudiswa, iyo inopfuura 300 volts.Chenjera.Shandisa multimeter kuyera kumberi uye kudzosera kuramba kumagumo ese eiyo AC tambo yemagetsi uye yekuchaja mamiriro eiyo capacitor.Iko kupikisa kukosha hakufaniri kunge kwakaderera, kana zvisina kudaro panogona kunge kune pfupi pfupi mukati memagetsi.Capacitors anofanira kukwanisa kuchaja uye kuburitsa.Bvisa mutoro uye kuyera kupikisa kwepasi kweboka rimwe nerimwe rezviteshi zvekubuda.Kazhinji, tsono yemamita inofanira kuva ne capacitor kuchaja uye kuburitsa oscillation, uye chiratidzo chekupedzisira chinofanira kunge chiri kukosha kwekupokana kwekupokana kwekubuda kwedunhu.

(2) Simba pakuona

Mushure mekuita simba, tarisa kana magetsi apisa fuse uye zvikamu zvega zvinobudisa utsi.Kana zvakadaro, bvisa magetsi panguva yakakodzera yekugadzirisa.

Ongorora kana paine 300V inobuda kumagumo ese e-high-voltage filter capacitor.Kana zvisiri, tarisa kutarisa iyo rectifier diode, sefa capacitor, nezvimwe.

Edza kana iyo yechipiri coil ye-high-frequency transformer ine zvakabuda.Kana pasina chinobuda, tarisa kutarisa kuti switch chubhu yakakuvara here, ingave iri kudedera, uye kuti dunhu rekudzivirira riri kushanda here.Kana iripo, tarisa kutarisa rectifier diode, filter capacitor, three-way regulator chubhu, nezvimwewo padivi rimwe nerimwe rinobuda.

Kana magetsi atanga uye akamira pakarepo, ari munzvimbo yakachengetedzwa.Iyo voltage yePWM chip yekudzivirira yepini yekupinda inogona kuyerwa zvakananga.Kana iyo voltage inodarika kukosha kwakatarwa, inoratidza kuti magetsi ari munzvimbo yakachengetedzwa, uye chikonzero chekudzivirira chinofanira kunyatsotariswa.
