China Supplier CJM1-400L/4300 Multi-Purpose industry MCCB Molded case circuit breaker
Product Model
CJ:Kodhi yebhizinesi
M:Mould kesi circuit breaker
1:Design Nhamba
□:Yakayerwa ikozvino yefuremu
□:Kutyora kugona hunhu kodhi/S inoreva yakajairika mhando (S inogona kusiiwa)H inoreva mhando yepamusoro
Cherechedzo: Kune mhando ina dzema neutral pole (N pole) yezvikamu zvina chigadzirwa. The neutral pole yerudzi A haina kugadzirwa ne over-current tripping element, inogara yakabatidzwa, uye haina kubatidzwa kana kudzimwa pamwe chete nezvimwe. matanda matatu.
Bango rakarerekera rerudzi B harina kurongedzerwa ne-over-current tripping element, uye rinobatidzwa kana kudzima pamwe chete nemamwe mapango matatu (i neutral pole inobatidzwa isati yadzimwa) yazvino, uye inobatidzwa kana kudzima pamwe chete nemamwe matanda matatu (iyo isina kwairi danda inobatidzwa isati yadzimwa) Iyo isina kwayakarerekera yerudzi D inoshongedzerwa nepamusoro-ikozvino chinhu chekutsika, inogara ichibatidzwa uye haibatiswe. pamusoro kana kudzika pamwe chete nemamwe matanda matatu.

Chii chinonzi MCCB?
Molded case circuit breakers zvigadziriso zvemagetsi zvakagadzirirwa kuchengetedza dunhu remagetsi kubva kune yakawandisa ikozvino.Iyi yakawandisa ikozvino inogona kukonzerwa nekuda kwekuremerwa kana kupfupika kwedunhu.Iyo molded kesi circuit breakers inogona kushandiswa muhupamhi hwemagetsi uye ma frequency ane yakatsanangurwa yakaderera uye yepamusoro muganho weinogadziriswa rwendo marongero.Pamusoro pemakina ekugumbusa, maMCCB anogona zvakare kushandiswa semanyorerwo ekudzimisa switch kana paine emergency kana kugadzirisa mabasa.MCCBs akamisikidzwa uye akaedzwa overcurrent, voltage surge, uye kuchengetedzwa kukanganisa kuti ive nechokwadi chekushanda kwakachengeteka munzvimbo dzese nemashandisirwo.Ivo vanoshanda zvinobudirira sereset switch yedunhu remagetsi kudzima simba uye kuderedza kukuvadzwa kunokonzerwa nekuremerwa kwedunhu, kukanganisa kwepasi, mapfupi maseketi, kana ikozvino inodarika iyo inomisikidza ikozvino.
Applications
Iko kushandiswa kweakaumbwa kesi circuit breakers (MCCBs) mumaindasitiri akasiyana kwakashandura mashandisirwo emagetsi masisitimu.Iyo MCCB chinhu chakakosha kuti ive nechokwadi chekuchengetedza uye kushanda zvakanaka kwedunhu.Vanopa dziviriro kubva pakuremerwa, mapfupi maseketi, uye kumwe kukanganiswa kwemagetsi, izvo zvakakosha mukudzivirira tsaona dzemagetsi uye njodzi dzemoto.
Imwe yemabhenefiti makuru eMCCBs kugona kwavo kubata yakakwira mafungu.Izvo zvakanyatsogadzirirwa kuchengetedza nekudzora maseketi ane simba rakawanda rekuda.Maindasitiri akadai sekugadzira, migodhi, oiri uye gasi, uye zvekufambisa zvinovimba zvakanyanya neMCCBs kuchengetedza midziyo yavo yemagetsi yakakosha uye zvivakwa.Kugona kweMCCBs kubata zvakanaka mafungu emhepo uye kudzima otomatiki magetsi kana yawandisa kana kutadza kunoita kuti MCCBs ive yakakosha mumaindasitiri aya.
Imwe mukana wakakosha weMCCB kuve nyore kwayo kuisa uye kushandisa.Iwo akakwana muhukuru uye anogona kubatanidzwa nyore nyore mumabhodhi uye switchboards.Yavo modular dhizaini inobvumira inochinjika kumisikidzwa, ichiita kuti ienderane kune akasiyana ekuisa zvinodiwa.Mukuwedzera, MCCBs inowanikwa muhuwandu hwehuwandu hwehuwandu hwemazuva ano, kuve nechokwadi chekuenderana nemagetsi akasiyana-siyana.Kureruka kwekuisa uye kushandisa kunoita kuti MCCBs ive sarudzo yakakurumbira yekumisikidza mitsva uye retrofits kune iripo magetsi masisitimu.
Kurongeka uye kuvimbika kweMCCBs kunoita basa rakakosha mukuona kusakanganiswa kushanda kwemagetsi masisitimu.MCCBs vane nzira dzekufambisa dzepamusoro dzinoona uye dzinopindura kukanganisa kwemagetsi.Iwo akashongedzerwa nemhando dzakasiyana dzemasensa uye masensa akadai seanopisa, magineti, emagetsi, nezvimwe, ayo anogona kuona abnormal magetsi mamiriro.Kana kukanganisa kwaonekwa, MCCB inofamba uye pakarepo inobvisa magetsi, kudzivirira imwe kukuvara.
MCCBs zvakare inobatsira kuvandudza simba rose rekuita kwemagetsi masisitimu.Nekudzivirira zvinobudirira kubva kumagetsi kutadza uye kuwandisa, ivo vanodzivirira kupisa kwakanyanya chizvarwa uye kupambadza kusingakoshi kwemagetsi.Izvi hazvingodzikisi njodzi yekukuvara kwemidziyo, asi zvakare inogonesa kushandiswa kwesimba.Nekuwedzera kuri kuita vanhu kusimbisa simba rekuchengetedza uye kusimudzira kwakasimba, kushandiswa kweakaumbwa kese mabreaker akakosha kuti ive nechokwadi chekushanda kwakanaka uye kwehushamwari mumaindasitiri akasiyana.
Muchidimbu, kushandiswa kwakakura kwemakasi akaumbwa emagetsi emagetsi kwakavandudza zvakanyanya kuchengetedzwa, kuvimbika uye kugona kwemagetsi masisitimu mumaindasitiri akasiyana.Kugona kwavo kubata makwikwi akakwira, nyore kuisirwa, kunyatsoona kukanganisa, uye kubatsira mukugonesa simba kunoita kuti zvive zvinhu zvakakosha mukudzivirira nekutonga kwemagetsi.Sezvo tekinoroji ichifambira mberi, akaumbwa ekesi anotyora anoenderera mberi nekushanduka kuti asangane nezviri kukura zvemazuva ano magetsi masisitimu.Sezvo maindasitiri ari kuramba achivimba nemagetsi kuti ashande, basa reMCCB mukuona kuti masekete akashanda zvakachengeteka uye zvine hungwaru anozonyanya kukosha.
