Melao-motheo ea lihlopha le lihlopha tsa li-contactor

Li-contactor ke likarolo tsa bohlokoa litsamaisong tsa motlakase 'me li sebelisoa ho laola phallo ea motlakase potolohong. Li sebelisoa lits'ebetsong tse fapaneng, ho kenyeletsoa mechini ea indasteri, litsamaiso tsa ho futhumatsa le ho futhumatsa moea, le lisebelisoa tsa lipalangoang. Li-contactor li arotsoe ho latela mofuta oa motlakase oo li o laolang. Lihlopha tse peli tse ka sehloohong ke li-contactor tsa AC le li-contactor tsa DC. Sehloohong sena, re tla hlahloba melao-motheo ea lihlopha le lihlopha tsa li-contactor, re shebane haholo-holo le li-contactor tsa AC.

Li-contactor tsa ACli etselitsoe ho laola motlakase o fapanyetsanang (AC), ho fapana le li-contactor tsa DC, tse etselitsoeng ho laola motlakase o tobileng (DC). Phapang pakeng tsa mefuta e 'meli ea li-contactor e ipapisitse haholo le potoloho e kholo eo li hokahaneng ho eona. Haeba motlakase o potolohong e kholo e le AC, contactor ke contactor ea AC ho sa tsotelehe motlakase oa coil ea taolo. Molao-motheo ona oa ho arola o netefatsa hore li-contactor lia lumellana le mofuta o itseng oa motlakase oo li etselitsoeng ho o laola.

Mokhahlelong oa contactor ea AC, ho na le mefuta e 'meli e meholo: contactor ea motlakase le contactor ea vacuum. Li-contactor tsa motlakase tsa AC li sebelisa mekhoa ea motlakase, litsamaiso tsa ho ikopanya, lisebelisoa tsa ho tima arc le likarolo tse thusang ho laola phallo ea motlakase o fapanyetsanang potolohong e kholo. Motheo oa contactor ea AC o entsoe ka maqephe a tšepe a silicon a laminated, e leng molemo ho fokotsa tahlehelo ea motlakase oa eddy le hysteresis e bakoang ke masimo a makenete a fapanyetsanang. Ho phaella moo, lesale la potoloho e khuts'oane le kenngoa qetellong ea motheo oa tšepe ho felisa ho thothomela le lerata ha motlakase oa AC o tšela lefela, ho netefatsa ts'ebetso e boreleli le e sebetsang hantle.

Ka lehlakoreng le leng, di-contactor tsa vacuum le tsona di wela sehlopheng sa di-contactor tsa AC mme di etseditswe ditshebediso tse nang le bokgoni bo hodimo. Di-contactor tsena di na le sesebediswa sa ho tima arc sa ceramic se kentsweng ka sekgeo se sebetsang hantle haholo ho tima arc tse hlahiswang ha contactor e fetola dipotoloho tsa AC. Theknoloji ena e tswetseng pele e thusa di-contactor tsa vacuum ho sebetsana le meroalo e meholo ya AC ka nepo le ka botshepehi.

Ha o kgetha contactor ya AC bakeng sa tshebediso e itseng, ho bohlokwa ho nahana ka mofuta le bokgoni ba mojaro. Haeba sistimi ya taolo e na le meroalo ya AC haholoholo mme motlakase wa DC kapa bokgoni ba mojaro wa DC bo le bonyenyane, contactor tsa AC di ka sebediswa bakeng sa taolo. Leha ho le jwalo, ho bohlokwa ho netefatsa hore tekanyo ya hajwale ya mabitso e lekane ho sebetsana le mojaro ntle le mathata.

Ka bokhutšoanyane, melao-motheo ea ho arola le ho arola li-contactor e bapala karolo ea bohlokoa ho netefatseng hore litsamaiso tsa taolo ea motlakase lia lumellana le ho sebetsa hantle. Li-contactor tsa AC li etselitsoe ho laola matla a AC 'me li fumaneha ka mefuta e mengata ho latela bokhoni le lits'ebetso tse fapaneng. Ka ho utloisisa melao-motheo ea ho arola le ho khetha contactor e loketseng bakeng sa ts'ebeliso e itseng, likhoebo li ka netefatsa ts'ebetso e boreleli le e tšepahalang ea litsamaiso tsa tsona tsa motlakase. Ebang ke mechini ea indasteri, litsamaiso tsa ho futhumatsa le tsa moea o pholileng, kapa lisebelisoa tsa lipalangoang, li-contactor tsa AC ke likarolo tsa bohlokoa bakeng sa ts'ebetso e ntle le polokeho.

Sehlopha sa Mutai se bokelletse boiphihlelo ba lilemo tse fetang leshome ba tlhahiso le thekiso holi-circuit breaker, li-contactor, matla a mabelili-switch tsa phetisetso ea othomathiki (ATS) le masimo a amanang le ona. Re labalabela monyetla oa ho sebetsa le uena ka tjantjello.
