AC contactorsakakamurwa kuita AC contactors (yekushanda voltage AC) uye DC contactors (voltage DC), ayo anoshandiswa muinjiniya yemagetsi, midziyo yekugovera magetsi uye nzvimbo dzeinjiniya dzemagetsi.AC contactor theoretically inoreva mudziyo wemumba unoshandisa coil kugadzira munda wemagetsi zvinoenderana nehuwandu hwekugadzirwa kwemaindasitiri ikozvino kudzima AC yekubata kudzora mutoro.
AC contactor isimba chinja uye kudzora redunhu rinowanzoshandiswa seachichinja magetsi.Inoshandisa iyo huru yekubata kumeso kubatidza uye kudzima dunhu remagetsi, uye inoshandisa yekubatsira yekubata nzvimbo kuita chirongwa chekutonga.Iyo huru yekubata kumeso kazhinji inongove yekuvhura nekuvhara yekuonana nzvimbo, uye yekubatsira yekubatanidza nzvimbo inowanzova nembiri mbiri dzenzvimbo dzekusangana dzine mabasa ekuvhura nekuvhara uye anowanzo kuvharwa.Diki AC contactors anowanzo shandiswa sediki relays uye huru simba maseketi.Iyo yekubatanidza pamusoro peiyo AC contactor yakagadzirwa nesirivheri-tungsten alloy, ine yakanaka conductivity yemagetsi uye inopisa inoputika kuramba.
A DC contactor is an AC contactor inoshandiswa mune DC redunhu.Inopindirana ne AC contactor uye kazhinji ine nzvimbo huru yekuonana.Batsira nenzvimbo dzekubatanidza uye coil yekuonana nzvimbo.Tora iyo DC contactor inoratidzwa mumufananidzo semuenzaniso.Inotora modularization uye inogona kuunganidza maitiro ekubata uye nzira dzekubata dzinodiwa nevatengi (kazhinji inovhurwa, kazhinji inodzimwa uye kuchinjwa);Ichi chigadzirwa chakatevedzana chine yakakwira yekubata simba switch inoshanda voltage uye nhanho inovhuvhuta yemagetsi munda arc kudzimisa, iyo yakanyanya simba switch inoshanda voltage inogona kuwanikwa 220VDC.Ichi chigadzirwa chakakodzera system control switching power supply kana ups power system software, yemagetsi forklift, simba idzva remagetsi mota yekuvaka muchina system software.
Izvo zvimiro uye misimboti yeDC contactors zvakangofanana neaya eAC contactors, uye iwo zvakare akaumbwa nemagetsi induction sangano, touch system software uye arc yekudzima michina, asi iyo electromagnetic induction sangano rakasiyana.
Kazhinji kutaura, mutsauko uripo pakati pechimiro cheDC contactor uye AC contactor zvinoenderana ne: iyo iron core coil haisi nyore kukonzera eddy uye eddy ikozvino kurasikirwa kukuvadzwa zvinoenderana neiyo DC magetsi, saka hazvisi nyore kupisa.Kuti zvive nani kufambisa kugadzirwa uye kugadzirisa, iyo musimboti wesimbi inogadzirwa nesimbi yakapfava.Kuti iite zvirinani kuti coil kupisa kupisa kwakanakisa, iyo coil inowanzokuvadzwa kuita yakaonda cylindrical chimiro, iyo inobata zvakananga iyo iron core, iri nyore kwazvo kupisa kupera.Ngatitarisei misiyano mina pakati DC contactors uye AC contactors.
Musiyano wakakosha ndeye AC contactor uye DC contactor.
1. Isimbi yesimbi yakasiyana-siyana: iyo iron core ye AC contactor inokonzera eddy uye eddy ikozvino kurasikirwa kwekukuvadza, nepo DC contactor isina simbi core kukuvara.Naizvozvo, musimboti wesimbi weiyo AC contactor inoumbwa nesilicon simbi mahwendefa ane anopindirana insulating akaturikidzana, kazhinji E-shaped;iyo iron core yeDC contactor inogadzirwa nesimbi yakapfava, mazhinji ayo ane U-shaped.
2. Iyo software yearc yekudzima system yakasiyana: grid arc yekudzima midziyo inosarudzwa kune AC contactor, uye iyo magnetic blowing arc yekudzima mudziyo inosarudzwa kune DC contactor.
3. Nhamba yekoil inotendeuka yakasiyana: nhamba yekoil inotendeuka ye AC contactor idiki, nhamba yekutendeuka kweDC contactor coil inonyanya kuwanda mumagetsi emagetsi eDC, AC contactor yakakamurwa kuita AC circuit, uye DC contactor yakakamurwa kuita DC redunhu.
4. Iyo chaiyo yekushanda frequency yakasiyana: iyo AC contactor ine yakakura yekushanda ikozvino, iyo yakawanda ndeye 600 nguva / awa, uye kushandiswa kwakaderera-mutengo.Iyo DC contactor inogona kusvika 2000 nguva / awa, uye mutengo wekushandisa wakakura.
Ko AC contactors uye DC contactors inogona kuchinjana here?
1. The AC contactor inogona kushandiswa kuDC contactor munguva yekukurumidzira, uye nguva yekudhonza-mukati haigoni kudarika maawa maviri (nokuti kupisa kwekushisa kwe AC coil kwakaipisisa kupfuura iyo DC, iyo inorara mune zvakasiyana-siyana). .Zvakanakisa kubatanidza kushorwa munhevedzano neiyo AC coil, asi DC haigone kutsiva iyo AC contactor;
2. Nhamba yekutendeuka kweAC contactor coil idiki, uye nhamba yekutendeuka kweDC contactor coil yakakura.Kana iyo ikozvino yedunhu guru remagetsi yakakura kwazvo (IE250A), iyo AC contactor inoshandisa yakatevedzana-yakabatana kaviri-inopeperesa coil;
3. Iyo DC relay coil resistor yakakura uye ikozvino idiki.Kana isina kuparadzwa nyore nyore nekubatanidza kune AC simba, ndapota iise ipapo ipapo.Nekudaro, iyo AC mota relay coil ine diki resistor uye yakawanda yazvino.Kana iyo yakabatana neDC inogadziriswa magetsi, iyo coil ichaparadzwa;
4. Nhamba yekutendeuka kwe AC contactor coil idiki uye resistor idiki.Kana iyo coil ichipinda mune inochinjika ikozvino, pachava neyakakura magineti induction friction resistance, iyo inodarika kure kupikisa kwecoil.Kiyi kune simba rekusimudzira recoil ihukuru hweiyo magineti induction friction resistance.Kana iyo DC yazvino yaizoyerera ichipinda mukati, iyo coil yaizove yakanyatso mira.Panguva ino, huwandu hwemazuva ano hunopfuura kuburikidza nekoiri huchave hwakanyanya kukura, zvichiita kuti coil inopisa kana kutopisa.Naizvozvo, AC contactors haigoni kushandiswa sezvo DC contactors.
