KunzwisisaMakaputsi eAC Akaumbwa Edunhu: Gwaro Rakazara
MaAC molded case circuit breakers (AC MCCBs) akakosha muinjiniya yemagetsi uye kugoverwa kwemagetsi. Anodzivirira macircuit kubva pakuwanda kwemagetsi uye mashort circuit, zvichiita kuti masisitimu emagetsi agare akachengeteka uye achibudirira. Chinyorwa chino chichaongorora mashandiro, mashandisirwo, uye mabhenefiti emaAC molded case circuit breakers (AC MCCBs) kuti akubatsire kunzwisisa zvizere chikamu ichi chakakosha.
Chii chinonzi AC MCCB?
Chinopwanya dunhu cheAC chakaumbwa (MCCB) chinoshandiswa kudzivirira macircuit circuit kubva pakuwandisa kwemagetsi. Kusiyana nemafuse echinyakare, ayo anofanira kutsiviwa mushure mekukanganisa, MCCB inogona kugadziriswazve mushure mekugumburwa, zvichiita kuti ive mhinduro iri nyore uye inoshanda yekudzivirira macircuit. "Chinopwanya dunhu" zvinoreva kuvakwa kwemudziyo, uchiisa zvikamu zvemukati mubhokisi repurasitiki rakasimba, zvichipa kudzivirira uye kudzivirira kubva kuzvinhu zvakatipoteredza.
AC MCCB inoshanda sei?
Kushanda kweAC MCCB kwakavakirwa panzira mbiri huru: kupisa kunokanganisa uye magnetic kunokanganisa.
1. Kufamba kwekupisa: Mudziyo uyu unoshandisa bimetallic strip inokotama kana paine magetsi akawandisa. Kana magetsi adarika mwero wakatarwa kwenguva yakati, strip inokotama zvakakwana kuti itange circuit breaker, nokudaro ichibvisa magetsi.
2. Kufamba neMagineti: Iyi nzira inokonzerwa nekukwira kwemagetsi kamwe kamwe, senge pakaitika circuit pfupi. Solenoid inogadzira simba remagineti rinodhonza lever, zvichiita kuti circuit breaker igumbuke nekukurumidza, nokudaro ichidzivirira circuit kubva mukukuvadzwa.
Kushandiswa kweAC Molded Case Circuit Breakers
MaAC molded case circuit breakers anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana. Mamwe mashandisirwo akajairika anosanganisira:
- Magadzirirwo eMaindasitiri: Mumafekitori nemafekitori ekugadzira, maAC MCCB anodzivirira michina nemidziyo kubva kumatambudziko emagetsi, zvichiita kuti mashandiro arambe achienderera mberi uye akachengeteka.
- Zvivako zveMabhizimisi: Muzvivako zvemahofisi nenzvimbo dzekutengesa, macircuit breaker aya anodzivirira masisitimu emagetsi, kudzivirira njodzi dzinogona kuitika uye kuona kuti mitemo yekuchengetedza inoenderana.
- Kushandiswa Kwedzimba: Varidzi vedzimba vanogonawo kubatsirwa neAC MCCBs sezvo vachidzivirira masisitimu emagetsi epamba, midziyo, nemidziyo.
- Masisitimu Esimba Rinodzokororwa: Nekukura kwemasisitimu esimba rezuva nemhepo, maAC MCCB ari kushandiswa zvakanyanya kudzivirira ma inverter nezvimwe zvikamu kubva kumatambudziko emagetsi.
Mabhenefiti eAC Molded Case Circuit Breakers
Kushandisa AC MCCB kune zvakanakira zvakawanda pane nzira dzechinyakare dzekudzivirira dunhu:
1. Inogona kugadziriswazve: Kusiyana nemafuse anofanira kutsiviwa mushure mekukanganisa, maMCCB anogona kugadziriswazve zviri nyore, zvichideredza nguva yekushanda uye mari yekugadzirisa.
2. Magadzirirwo Anogadziriswa: MaAC MCCB mazhinji anouya nemagadzirirwo erwendo anogadziriswa, zvichibvumira mushandisi kugadzirisa mwero wedziviriro zvichienderana nezvinodiwa zvedunhu.
3. Dhizaini Yakabatana: Dhizaini yedzimba dzakaumbwa haitore nzvimbo yakawanda, zvichiita kuti zvive nyore kuisa munzvimbo dzakamanikana.
4. Kuchengetedzwa Kwakawedzerwa: Nekupa dziviriro yakavimbika yekuwedzera simba uye yepfupi-circuit, maAC MCCB anovandudza kuchengetedzeka kwese kwemasisitimu emagetsi.
5. Kugara kwenguva refu: Kugadzirwa kwakasimba kweMCCB kunoita kuti igare kwenguva refu uye ive yakavimbika kunyangwe munzvimbo dzakaoma.
Muchidimbu
Zvichitaurwa zviri nyore, maAC molded case circuit breakers (MCCBs) zvinhu zvakakosha mumagetsi emazuva ano, zvichipa dziviriro yakavimbika yemagetsi akawandisa uye mashort-circuit. Kugona kwawo kushandisa zvinhu zvakasiyana-siyana, nyore kushandisa, uye kuchengetedzeka kunoita kuti ave sarudzo yepamusoro yekushandiswa kwakasiyana-siyana, kubva kumaindasitiri kusvika kudzimba. Kunzwisisa mashandiro uye mabhenefiti emaAC molded case circuit breakers kwakakosha kune chero munhu anoshanda muinjiniya yemagetsi kana kugovera magetsi, sezvo zvichiita kuti masisitimu emagetsi agare akachengeteka uye achishanda zvakanaka. Sezvo tekinoroji ichiramba ichifambira mberi, maAC molded case circuit breakers pasina mubvunzo achaita basa rakakosha mukutsvaga mhinduro dzemagetsi dzakachengeteka uye dzinoshanda zvakanaka.
