Musiyano pakati peDC Contactor uye AC Contactor

1. AC contactor inotora grid plate arc yekudzimisa mudziyo, nepo DC contactor inotora magineti inofuridza arc yekudzima mudziyo.

2. Ikozvino yekutanga yeA AC contactor yakakura, uye nguva yekushanda kwayo inosvika kusvika ku600 nguva / h, uye nguva yekushanda yeDC contactor inogona kusvika kusvika ku1200 nguva / h.

3. Iron core ye AC contactor ichabudisa eddy current uye hysteresis kurasikirwa, nepo DC contactor isina iron core kurasikirwa. Naizvozvo, iyo simbi yesimbi ye AC contactor inogadzirwa nelaminated silicon simbi mapepa ayo akavharidzirwa kubva kune mumwe nemumwe, uye anowanzo gadzirwa kuita E chimiro; musimboti wesimbi weDC contactor wakagadzirwa nechidimbu chesimbi yakapfava, uye mazhinji acho anogadzirwa kuita chimiro cheU.

4. Sezvo AC contactor inopfuura imwe-phase AC simba, kubvisa kuzununguka uye ruzha runogadzirwa ne electromagnet, pfupi-circuit mhete inosungirirwa pamagumo ekupedzisira kweiyo static iron core, nepo DC contactor isingadiwi.

5. Iyo AC contactor inogona kutsiviwa neDC contactor munguva yekukurumidzira, uye nguva yekudhonza-mukati haigoni kudarika maawa maviri (nokuti kupisa kwekupisa kwe AC coil kwakaipa kupfuura iyo DC, iyo inotarirwa nemaitiro avo akasiyana. ) Zvakanakisisa kuishandisa kwenguva yakareba. Pane chinopikisa mu AC coil, asi DC haisi inotsiva AC kontrakta.

6. Nhamba yekoil inotendeuka ye AC contactor idiki, uye nhamba yekoil inotendeuka yeDC contactor yakakura. Kuwanda kwekoiri kunogona kusiyaniswa. Panyaya yekunyanyisa ikozvino munharaunda huru (Ie> 250A), iyo contactor inoshandisa mutsara miviri miviri.

7. Kuita kwekoiri yeDC relay yakakura uye ikozvino idiki. Kana zvichinzi haizokanganiswe kana yakabatana neAC simba, inguva yekuiburitsa. Nekudaro, kuita kwecoil ye AC relay idiki, uye iripo yakakura. Kana iyo yakabatanidzwa kune yakananga ikozvino, iyo coil ichakuvadzwa.

8. The AC contactor ane pfupi-redunhu mhete pamusoro simbi musimboti. Muchidimbu, hapafanirwe kunge paine AC contactor pane DC contactor. Iyo musimboti wesimbi unowanzo yakamisikidzwa nesilicon simbi mashiti kudzikisa eddy ikozvino uye magineti inogadzirwa neinotsinhanisa magineti musimbi musimboti. Hysteresis kurasikirwa kudzivirira kupisa kwesimbi musimboti. Iyo simbi musimboti muDC contactor coil haiburitse eddy currents, uye iyo DC iron core haina dambudziko rekudziya, saka iyo musimboti wesimbi unogona kugadzirwa ne monolithic cast simbi kana simbi yakakandwa. Iyo coil yedunhu reDC haina inductive reactance, saka iyo coil ine nhamba yakakura yekutendeuka, kupikisa kukuru, uye kurasikirwa kukuru kwemhangura. Nokudaro, kupisa kwekoiri pachayo ndicho chinhu chikuru. Kuita kuti coil ive yakanaka kupisa kupisa, iyo coil inowanzoitwa yakareba uye yakaonda cylindrical chimiro. Iyo coil ye AC contactor ine mashoma ekutendeuka uye kushoma kuramba, asi iyo iron core inoburitsa kupisa. Iyo coil inowanzo gadzirwa kuita gobvu uye pfupi cylindrical chimiro ine imwe gap pakati payo nesimbi musimboti kufambisa kupisa kupisa uye panguva imwechete kudzivirira iyo coil kubva pakupisa nekupisa. . Kuti ubvise kuzunguzika uye ruzha rwunogadzirwa nemagetsi emagetsi, iyo AC contactor ine pfupi-yedunhu mhete yakamisikidzwa kumagumo eiyo static iron core, nepo DC contactor isingade pfupi-circuit ring.
