Chii chinonzi MCCB?
Ma "molded case circuit breakers" zvishandiso zvekudzivirira magetsi zvakagadzirirwa kuchengetedza circuit yemagetsi kubva kumagetsi akawandisa. Ma "current" aya akawandisa anogona kukonzerwa nekuwanda kwemagetsi kana kuti short circuit. Ma "molded case circuit breakers" anogona kushandiswa mumagetsi akasiyana-siyana uye ma "frequency" ane "depth" ne "up" muganhu wakatarwa we "trip settings" unogadziriswa. Kuwedzera kune "tripping mechanisms", ma "MCCB" anogonawo kushandiswa se "manual disconnection switches" kana paine emergency kana "maintenance operations". Ma "MCCB" akajairwa uye akaedzwa kuti aone kana paine overcurrent, voltage surge, uye fault protection" kuitira kuti ave nechokwadi chekuti anoshanda zvakachengeteka munzvimbo dzese nemashandisirwo. Anoshanda zvinobudirira se "reset switch" ye "electrical circuit" kuti abvise magetsi uye kuderedza kukuvara kunokonzerwa ne "circuit overload", "ground fault", "short circuit", kana "current" inopfuura "current limitation".
Kukosha kweMolded Case Circuit Breakers mukuona kuchengetedzeka kwemagetsi
Munyika yanhasi yanhasi, magetsi chinhu chakakosha muhupenyu hwedu hwezuva nezuva. Kubva pakuisa magetsi mudzimba dzedu kusvika pakushandisa michina yemaindasitiri, kuve nechokwadi chekuti masisitimu emagetsi akachengeteka uye akavimbika kwakakosha. Molded case circuit breaker (MCCB) chinhu chakakosha chinoita basa rakakosha. Mublog rino, tichaongorora kukosha kweMCCBs mukuona kuti magetsi akachengeteka.
MCCB mudziyo wekudzivirira magetsi wakagadzirirwa kuchengetedza maseketi nemidziyo kubva pakuwanda kwemagetsi uye maseketi mapfupi. Anowanzoshandiswa mudzimba, mabhizinesi nemaindasitiri kudzivirira kukuvara kwemagetsi uye, chinonyanya kukosha, kuderedza njodzi yemoto wemagetsi.
Rimwe remabasa makuru eMCCB nderekumisa kuyerera kwemagetsi kana paine kuwanda kwemagetsi kana kuti kupfupika kwemagetsi. Izvi zvakakosha kudzivirira waya nezvinhu kuti zvisapise zvakanyanya, izvo zvinogona kukonzera moto nekukuvara kukuru. Nekugumbura macircuit uye kudzima magetsi, maMCCB anobatsira kudzivirira njodzi dzinogona kuitika uye kudzivirira vanhu nepfuma.
Pamusoro pezvo, MCCB inopa mukana wekuti masisitimu emagetsi ave nyore uye anochinjika. Anogona kugadziriswa zviri nyore mushure merwendo, zvichibvumira magetsi kuti adzorerwe nekukurumidza pasina chikonzero chekutsiva chero chinhu. Izvi hazvingochengetedzi nguva nesimba chete, asi zvinoderedzawo nguva yekushanda uye kukanganiswa kwekushanda kwezuva nezuva.
Pamusoro pebasa rawo rekudzivirira njodzi dzemagetsi, ma "molded case circuit breakers" anobatsira kuvandudza kushanda zvakanaka uye kuvimbika kwemasystem emagetsi. Nekudzivirira kubva pakuwanda kwemagetsi uye ma "short circuit", anobatsira kuchengetedza kushanda kwemidziyo yemagetsi uye kuwedzera hupenyu hwebasa rayo. Izvi zvinoderedza kudiwa kwekugadzirisa kunodhura uye kutsiva, zvichichengetedza nguva nemari kwenguva refu.
Zvakakosha kuziva kuti haasi ese maMCCB akafanana. Pakusarudza MCCB yekushandisa chaiyo, zvakakosha kufunga nezvezvinhu zvakaita se current rating, breaking capacity uye operating voltage. Izvi zvinofanirwa kuenzaniswa nezvinodiwa nemagetsi kuti zvive nechokwadi chekuchengetedzwa uye kushanda zvakanaka.
Pamusoro pezvo, kugadziriswa nekuongororwa kweMCCB nguva dzose kwakakosha kuti ive nechokwadi chekuti inoramba ichishanda zvakanaka. Kuongorora nekuongororwa nguva dzose kunogona kubatsira kuona chero matambudziko angangoitika kana kupera saka kugadzirisa kana kutsiva kunogona kuitwa sezvinodiwa.
Mukupfupisa, ma "molded case circuit breakers" anoita basa rakakosha mukuona kuchengetedzeka kwemagetsi uye kuvimbika. Nekudzivirira kubva mukuwanda kwemagetsi uye ma "short circuit", anobatsira kudzivirira njodzi dzemagetsi uye kuderedza njodzi yemoto. Pamusoro pezvo, anobatsira kuwedzera kushanda zvakanaka uye kugara kwenguva refu kwema "systems" emagetsi, zvichiita kuti ave chinhu chakakosha mukuisa magetsi kwemazuva ano. Kuisa mari mu "MCCB" yemhando yepamusoro uye kuve nechokwadi chekuti yakachengetedzwa zvakanaka kwakakosha kudzivirira vanhu nepfuma kubva kunjodzi dzemagetsi. Tinofunga kuti zvinofungwa nevatengi, kukurumidza kwekuita mukati mezvido zvevatengi ve "principle", zvichibvumira mhando yepamusoro, kuderedza mari yekugadzirisa, mari dzinonzwisisika, zvakapa vatengi vatsva nevekare rutsigiro nekusimbisa Factory zvakananga MCCB CJM3 Series Moulded Case Circuit Breaker CE CB, Tave tichitarisira nemwoyo wese kushanda pamwe nevatengi pasi rese. Tinotenda kuti tinogona kukugutsai. Tinogamuchirawo neushamwari vatengi vanouya kukambani yedu nekutenga zvinhu zvedu.
