Circuit breaker (MCCB) kushanda musimboti uye basa

Ndeipi basa redunhu rebreaker, iyo inoshanda musimboti wedunhu breaker inotsanangurwa yakadzama
Kana iyo sisitimu yatadza, chiitiko chekudzivirira chechinhu chinokanganisa uye kutadza kushanda kwedunhu rinoramba kufamba, fambisa padhuze wedunhu redunhu rechiteshi kuburikidza nekuchengetedzwa kwechinhu chinokanganisa, uye chiteshi chinogona zvakare kushandiswa kugadzira waya. iyo distal circuit breaker rwendo panguva imwechete inonzi circuit breaker failure protection.
Kazhinji, mushure mekuita kwechikamu chezvino zvikamu, iwo mapoka maviri ekutanga mapoinzi anobuda, uye ekunze chiito chekudzivirira mapoinzi akabatanidzwa munhevedzano mudunhu, bhazi chinongedzo kana chikamu chedunhu breaker kutadza kutanga kutadza kudzivirira.
Ndeapi mabasa emagetsi emagetsi
Circuit breaker anonyanya kushandiswa mumamota anowanzo uye makuru emagetsi ekushandura uye zviteshi.Circuit breaker ine basa rekuparadzanisa mutoro wetsaona, uye inobatira pamwe neyakasiyana siyana relay kuchengetedza kuchengetedza midziyo yemagetsi kana mitsara.
Circuit breaker inowanzo shandiswa mukudzika-voltage mwenje, chikamu chemagetsi, chinogona kuita basa rekucheka otomatiki dunhu;redunhu rinotyora uye rinoremerwa uye pfupi dunhu kudzivirira uye mamwe akawanda mabasa, asi yakaderera mutoro dambudziko rinoda kugadziriswa ndiko disconnecting switch inotamba yemagetsi yekuzviparadzanisa nevamwe, uye redunhu redunhu creepage kureba harina kukwana.
Ikozvino kune redunhu rinotyora rine basa rekuzviparadzanisa nevamwe, inova yakajairwa wedunhu breaker uye disconnector basa maviri mune imwe.Iyo yedunhu inotyora ine basa rekuzviparadzanisa inogona zvakare kuve yemuviri disconnector.Muchokwadi, iyo disconnector switch haiwanzo shandiswe nemutoro, nepo wedunhu rinopaza riine dunhu diki, kuchengetedzwa kwekuremerwa, underpressure uye mamwe mabasa ekudzivirira.
Kushanda musimboti wedunhu breaker ine ruzivo
Basic mhando: Iyo yakapusa yekudzivirira yedunhu mudziyo ndiyo fuse.Iyo fuse ingori waya yakaonda kwazvo, ine inodzivirira kesi uye yobva yabatana nedunhu.Mushure mokunge dunhu rakavharwa, mafungu ose anofanira kuyerera kuburikidza nezvino pane fuse -- fuse seyazvino ikozvino pane dzimwe nzvimbo padunhu rimwe chete.Iyo fuse yakagadzirirwa kuti igone kusanganisa kana tembiricha yasvika pane imwe nhanho.Kuvhara fuse kunogona kukonzera migwagwa yakavhurika kudzivirira yakawandisa ikozvino kubva pakukuvadza imba wiring.Dambudziko nefuse nderekuti rinogona kushanda kamwe chete.Pese painopiswa fuse, inofanira kutsiviwa.Circuit breaker inogona kuita basa rimwechete semafusi, asi anogona kushandiswa kakawanda.Pakarepo iyo ikozvino inosvika padanho rine njodzi, inokurumidza kukonzera dunhu rakavhurika.
Nheyo yekutanga yekushanda: waya yemoto mudunhu yakabatana kune ese magumo ekuchinja.Kana switch yaiswa munzvimbo, iyo yazvino inoyerera ichibuda kubva pasi terminal, zvichitevedzana kuburikidza nemagetsi emagetsi muviri, nharembozha, static contacts, uye pakupedzisira kubva kumusoro terminal.Ikozvino inogona kuita magineti emagetsi emagetsi.Simba remagineti rinogadzirwa nemagetsi magineti rinowedzera neazvino, uye kana yazvino yadzikira.Kana iyo yazvino ichisvetuka kusvika padanho rine njodzi, chiitiko cheEM chinoburitsa simba remagineti rakakura rakakwana rekudhonza tsvimbo yesimbi yakabatana neiyo switch link.Izvi zvinokonzeresa kuti inofambisa contactor irereke uye kusiya iyo static contactor, yobva yacheka dunhu.Magetsi anovhiringwawo.The bimetal bhaa rakagadzirwa kwakavakirwa chete musimboti, musiyano ndechokuti hapana chikonzero kupa electromagnetic muviri simba pano, asi inobvumira simbi bhaa kukotama panguva yakakwirira, uye ipapo kutanga linkage mudziyo.Mamwe mabreaker edunhu anozadzawo zvinoputika kufambisa switch.Kana yazvino ikadarika imwe nhanho, inobatidza zvinhu zvinoputika yobva yatyaira piston kuvhura switch.
Mamodheru akakwenenzverwa: Madhigirii epamusoro epamusoro anosiya midziyo yemagetsi yakapfava uye panzvimbo pacho vanoshandisa midziyo yemagetsi (semiconductor zvishandiso) kutarisa mazinga aripo.Ground fault circuit breaker (GFCI) rudzi rutsva rwedunhu rinotyora.Iri redunhu rinoputika haringogoni kudzivirira kukanganisa kweimba wiring, asiwo kudzivirira vanhu kubva kumagetsi emagetsi.
Basa rakavandudzwa: Iyo GFCI inogara ichitarisisa ikozvino pa zero uye mitsetse yemoto mudunhu.Kana zvese zvakajairika, ikozvino pamitsetse miviri inofanira kunge yakafanana.Kamwe mutsara wemoto wakadzikwa zvakananga (somuenzaniso, mumwe munhu anokanganisa mutsara wemoto), ikozvino pamutsara wemoto unongoerekana wawedzera, nepo zero mutsara usingaiti.Iyo GFCI inodimbura dunhu nekukurumidza mushure mekuona mamiriro aya kudzivirira kukuvadzwa kwemagetsi.Nekuti iyo GFCI inogona kutora nhanho isina kumirira kusvika ikozvino yakwira kusvika padanho rine njodzi, inokurumidza kukurumidza kupfuura yakajairwa matunhu edunhu.
