Kunzwisisa Kuwedzeredza uye Pfupi Dziviriro Yedunhu muMolded Case Circuit Breakers: Basa reThermal Magnetic uye Electronic Tripping Mechanisms.

Mumunda wekugadzira magetsi, kuchengetedzwa uye kuvimbika kwemaitiro emagetsi kunonyanya kukosha. Chimwe chezvinhu zvakakosha izvo zvinoita kuti chengetedzo iyi ive yakaumbwa kesi circuit breaker (MCCB). Zvishandiso izvi zvakagadzirirwa kuchengetedza maseketi kubva pakuremerwa uye mapfupi maseketi anogona kukonzera njodzi kutadza uye njodzi. Ichi chinyorwa chinotarisa zvakadzama kuti akaumbwa sei nyaya dzemasaiti dzinotyora dzinowana kuwandisa uye dziviriro yedunhu pfupi kuburikidza nekupisa kwemagineti uye emagetsi ekufambisa nzira, ine tarisiro yakakosha pane zvitsva zvinounzwa ne.Iyo kambani Yuye Electrical Co., Ltd.

Kukosha Kwekudzivirirwa Kwedunhu

Usati waongorora maitiro eMCCBs, zvakakosha kuti unzwisise kukosha kwekuchengetedzwa kwedunhu. Kuwedzeredza kunoitika kana ikozvino inoyerera kuburikidza nedunhu inodarika kugona kwayo yakayerwa, zvichikonzera kupisa kwakanyanya. Kune rumwe rutivi, mapfupi mapfupi anoitika kana pane isingatarisirwi yakaderera-resistance nzira, zvichikonzera kukurumidza kusimuka kwezvino. Mamiriro maviri aya anogona kukonzera kukuvara kwemidziyo, njodzi dzemoto, uye kunyangwe kukuvara kwemunhu. Naizvozvo, nzira dzekudzivirira dzinoshanda dzakakosha kuchengetedza masisitimu emagetsi.

Molded Case Circuit Breakers: Overview

A molded case circuit breaker is a electromechanical device inovhiringa kufamba kwemagetsi kana paita kuwandisa kana kupfupika. Iwo anoshandiswa zvakanyanya mumaindasitiri, ekutengesa, uye ekugara zvikumbiro nekuda kwekuvimbika kwavo uye nyore kushandisa. Molded kesi circuit breakers dzakagadzirirwa kuvhura otomatiki dunhu kana kukanganisa kwaonekwa, nekudaro kudzivirira kukuvadzwa kwemagetsi system.

Tripping Mechanism: Thermal Magnetic vs Electronic

Pane nzira mbiri dzekufambisa dzinoshandiswa muMCCBs: thermal-magnetic uye electronic. Imwe neimwe meshini ine yayo yakasarudzika maficha uye mabhenefiti ayo anobatsira pakuita kwese kwese kweseki breaker.

Thermal Magnetic Trip Mechanism

Iyo yekupisa-magineti yerwendo meshini inosanganisa maviri akasiyana mabasa: yekudzivirira yekushisa uye kuchengetedzwa kwemagineti.

1. Kudzivirirwa kweThermal: Ichi chimiro chinobva pamusimboti wekupisa kunoitwa nekuyerera kwezvino. Iyo MCCB ine bimetallic tambo inokotama kana ikozvino ichifamba mairi. Kana iyo yazvino ichipfuura muganhu wepreset kwenguva yakareba, bimetallic strip inokotama zvakaringana kutsika dunhu, ichikanganisa kuyerera kwazvino. Iyi nzira inonyanya kushanda mukudzivirira kubva kune yakawandisa mamiriro.

2. Magnetic protection: Iyo magnetic component ye thermal magnetic mechanism yakagadzirirwa kutarisana nemapfupi mafupi. Inoshandisa electromagnet kugadzira magineti inoenderana neyazvino inoyerera nepadunhu. Kana dunhu rakapfupika richiitika, ikozvino inofamba nekukurumidza, zvichiita kuti magnetic field iwedzere zvakanyanya. Kana simba remagineti richipfuura imwe chikumbaridzo, rinoita kuti rwendo rwekufamba, rupaze dunhu uye kupa kuchengetedzwa nekukurumidza kubva pakukanganisa.

Thermal-magnetic tripping michina inosarudzwa nekuda kwekureruka kwavo, kuvimbika uye mutengo-kushanda.Iyo kambani Yuye Electric Co., Ltd.yanga iri kumberi kwekugadzira advanced thermal-magnetic MCCBs iyo yakasimudzira mashandiro uye kusimba kuti ive nechokwadi chekuti masisitimu emagetsi anoramba akachengetedzwa pasi pemamiriro akasiyana-siyana.

Electronic Rwendo Mechanism

Kana ichienzaniswa neyekupisa-magineti meshini, iyo yemagetsi rwendo meshini inoshandisa yepamusoro yemagetsi kutarisa ikozvino kuyerera kuburikidza nedunhu. Mechanichani iyi inopa akawanda mabhenefiti:

1. Yakanyatsojeka: Iyo yemagetsi rwendo nzira inopa yakanyatsojeka uye inogadziriswa kuwandisa uye pfupi-yedunhu kuchengetedza marongero. Vashandisi vanogona kugadzirisa marongero erwendo zvichienderana nezvinodiwa zvemagetsi avo.

2. Kumhanya: Zvigadzirwa zvemagetsi zvinogona kuona kukanganisa nekukurumidza kupfuura thermal-magnetic systems. Iyi inokurumidza kupindura nguva yakakosha kudzikisa kukuvadzwa panguva pfupi yedunhu chiitiko.

3. Zvimwe Zvimiro: MaMCCB mazhinji emagetsi ane zvinhu zvakadai sekugona kutaurirana, izvo zvinogonesa kutarisa kure uye kutonga. Izvi zvinonyanya kubatsira mumaindasitiri ekushandisa apo chaiyo-nguva data yakakosha kuchengetedza kuvimbika kwehurongwa.

Iyo kambani Yuye Electrical Co., Ltd.yakagamuchira kuvandudzwa kwemagetsi ekufambisa michina, kubatanidza tekinoroji yemazuva ano mumagadzirirwo ayo eMCCB. Yayo magetsi emagetsi emagetsi akagadzirirwa kupa kuchengetedzwa kwepamusoro uye kuchinjika kuti asangane nezvinodiwa zvakasiyana zvemazuva ano emagetsi masisitimu.

Molded kesi circuit breakers inoita basa rakakosha mukuona kuchengetedzeka uye kuvimbika kwemagetsi masisitimu nekupa zvinobudirira kuwandisa uye kupfupika kwedziviriro yedunhu. Sarudzo pakati pekupisa-magineti uye yemagetsi kufambisa masisitimu zvinoenderana nezvinodiwa chaizvo zvekushandisa. Thermal-magnetic MCCBs inopa nyore uye kuvimbika, nepo zvemagetsi MCCBs zvichipa humbowo uye maficha epamberi.

Yuye Electric Co., Ltd. ndiye mutungamiri mumunda, anogara achigadzira uye achinatsiridza ayo akaumbwa kesi yedunhu reki breaker zvigadzirwa kuti isangane nekuchinja kwezvinodiwa zveindasitiri. Nekunzwisisa masisitimu ari kuseri kweakaumbwa kesi mabreaker, mainjiniya uye matekinoroji vanogona kuita sarudzo dzine ruzivo dzinovandudza kuchengetedza uye kushanda zvakanaka kwemagetsi masisitimu. Sezvo tekinoroji ichienderera mberi, ramangwana rekudzivirira redunhu rinotaridzika kupenya, uye Yuye Electric Co., Ltd. iri pamberi pekuchinja uku.
