    Kushandiswa

    CJMM1 series molded case circuit breaker (inozonzi circuit breaker) inoshandiswa paAC 50/60HZ power distribution network circuit ine rated insulation voltage ye800V, rated operation voltage ye690V uye rated operation current kubva pa10A kusvika pa630A, inoshandiswa kuparadzira simba nekudzivirira circuit nemagetsi kuti zvisakuvadzwe nekuda kwekuwanda kwemagetsi, short circuit, under voltage nezvimwe zvikanganiso, inoshandiswawo pakutanga mota nguva zhinji pamwe nekuwanda kwemagetsi, short circuit uye under voltage protection. Iyi circuit breaker ine mabhenefiti e small volume, high breaking capacity, short arcing (kana noarcing) etc, inogona kugadzirirwa zvishandiso zvakaita se alarm contact, shunt release, assistance contact etc, chigadzirwa chakanakira mushandisi. Residual current circuit breaker inogona kuiswa yakatwasuka (vertical installation) kana kuiswa yakatwasuka (horizontal installation). Chigadzirwa ichi chinoenderana nezvinodiwa neIEC60947-2 neGb140482.

    Chii chinonzi DC MCCB?

    Kunzwisisa DC MCCB: Gwaro Rakazara

    Munyaya dzeinjiniya yemagetsi nekugoverwa kwesimba, izwi rekuti "MCCB" rinowanzoonekwa. MCCB inomirira Molded CaseMuputsi wedunhuuye chinhu chakakosha mukudzivirira macircuit kubva ku overcurrent, short circuits nezvimwe zvinokanganisa magetsi. Kunyange hazvo ma AC MCCB achikurukurwa zvakanyanya, maDC MCCB akakoshawo, kunyanya mumashandisirwo anosanganisira ma direct current systems (DC). Iri blog rine chinangwa chekubvisa zvisizvo ma DC molded case circuit breakers uye kukurukura mabasa awo, mashandisirwo awo uye zvakanakira.

    Chii chinonzi DC molded case circuit breaker?

    DC Molded Case Circuit Breaker (DC MCCB) kana kuti DC Molded Case Circuit Breaker icircuit breaker yakagadzirirwa kuchengetedza macircuit eDC. Kusiyana nemamwe maAC, maDC MCCB akagadzirirwa kugadzirisa matambudziko akasiyana anokonzerwa neDC, akadai sekushaikwa kwenzvimbo yekuyambuka zero uye mukana wekuti pave nearcing isingaperi. Macircuit breaker aya akakosha mumaindasitiri akasiyana-siyana, anosanganisira simba rinogona kushandiswazve, kutakurwa uye kutaurirana, ayo anowanzo shandisa masisitimu emagetsi eDC.

    Muchina weDC molded case circuit breaker unoshanda sei?

    Basa guru reDC molded case circuit breaker nderekukanganisa magetsi kana paine overload kana short circuit. Heino nhanho nhanho yekushanda kwayo:

    1. Kuona: Muchina weDC molded case circuit breaker unoramba uchitarisa magetsi ari kufamba nemudunhu. Kana magetsi akadarika simba remuchina wecircuit breaker, nzira yekudzivirira inotangwa.

    2. Kukanganiswa: Kana magetsi akawandisa akaonekwa, circuit breaker inovhura ma contacts ayo kuti ivhiringidze kufamba kwemagetsi. Izvi zvinodzivirira kukuvara kwecircuit nemidziyo yakabatana.

    3. Kudzima Arc: Chimwe chezvinetso zvikuru muDC systems kuumbwa kwema arc. Kana ma contacts akavhurika, arc inoumbwa nekuda kwekuenderera mberi kweDC current. DC molded case circuit breakers dzine michina yekudzima arc, senge arc extinguishing chambers kana magnetic blow arc extinguishing devices, kuti dzibvise ma arc zvakachengeteka.

    4. Kugadzirisazve: Mushure mekunge dambudziko ragadziriswa, circuit breaker inogona kudzoserwa patsva nemaoko kana otomatiki kuti itangezve kushanda kwakajairika.

    Zvinhu zvikuru zveDC molded case circuit breaker

    Ma DC molded case circuit breakers ane zvinhu zvakawanda zvinoita kuti akodzere kushandiswa kweDC:

    - Kukwanisa Kuputsa Kwakanyanya: Dzakagadzirwa kuti dzikwanise kubata mafungu emagetsi ane fault currents akawanda, zvichiita kuti dziviriro yakavimbika kunyangwe munzvimbo dzakaoma.
    - Zviyero zveKufamba kweThermal neMagineti: Zviyero izvi zvinopa dziviriro mbiri kuburikidza nekupindura kune frequency yakareba (thermal) uye short circuit yenguva pfupi (magnetic).
    - Magadzirirwo Erwendo Anogadziriswa: MaDC MCCB mazhinji anopa magadzirirwo erwendo anogadziriswa, zvichibvumira kugadziriswa zvichienderana nezvinodiwa zvekushandisa.
    - Dhizaini Yakabatana: Dhizaini yedzimba dzakaumbwa inoita kuti dzive dzakasimba uye dzakasimba, zvichiita kuti zvive nyore kubatanidzwa mumhando dzakasiyana dzemasystem.

    Kushandiswa kweDC Molded Case Circuit Breaker

    Ma DC molded case circuit breakers anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana uye mamiriro ezvinhu:

    - Simba Rinodzokororwa: Masisitimu esimba rezuva, maturbine emhepo uye masisitimu ekuchengetera simba anowanzo shandisa maDC molded case circuit breakers kudzivirira macircuit avo.
    - Mota dzeMagetsi (EV): MaDC molded case circuit breakers anoshandiswa muzviteshi zvekuchaja mota dzemagetsi uye mumasystem ari mundege kuti ave nechokwadi chekuti mashandiro akachengeteka.
    - Kutaurirana: Zvivakwa zvekutaurirana zvinoshandisa simba reDC zvakanyanya zvinoshandisa macircuit breaker aya kuchengetedza michina yakakosha.
    - Kuzvigadzira Kwemaindasitiri: DC Molded Case Circuit Breakers inoshandiswa mumabasa akasiyana-siyana emaindasitiri uchishandisa maDC motors nemadhiraivha.

    Mabhenefiti ekushandisa maDC molded case circuit breakers

    - Kuchengetedzwa Kwakawedzerwa: MaDC molded case circuit breakers anowedzera kuchengetedzeka kwemasystem emagetsi nevashandi nekupa dziviriro yakavimbika ye overcurrent uye short circuit.
    - KUDEREDZERWA KWENGUVA YEKUDEREDZERA: Kukurumidza kukanganiswa kwekukundikana kunoderedza kukuvara uye kunoderedza nguva yekushanda, zvichiita kuti masisitimu akakosha arambe achishanda.
    - Inochengetedza Mari Yakawanda: Inodzivirira kukuvara kwemidziyo inodhura uye inoderedza mari yekugadzirisa, zvichiita kuti DC Molded Case Circuit Breakers ive mhinduro inoshanda zvishoma.

    Muchidimbu

    Muchina wekupwanya mabhokisi emagetsi weDC wakagadzirwa chinhu chakakosha mumagetsi emazuva ano, uchipa dziviriro yakasimba uye uchivimbisa kushanda kwakachengeteka kwemaseketi eDC. Kunzwisisa mashandiro awo, hunhu hwawo, uye mashandisirwo awo kunogona kubatsira mainjiniya nematekiniki kuita sarudzo dzine ruzivo pavanenge vachigadzira uye vachichengetedza masisitimu emagetsi eDC. Sezvo kudiwa kwemagetsi anogona kushandiswazve uye mota dzemagetsi kuri kuramba kuchikura, kukosha kwemaseketi emagetsi eDC akagadzirwa kuchawedzera, zvichiita kuti ave chikamu chakakosha chesimba redu.
