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 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".

Mashandisirwo

Kushandiswa kwema "molded case circuit breakers" (MCCBs) mumaindasitiri akasiyana-siyana kwakachinja mashandiro emagetsi. MCCB chinhu chakakosha pakuona kuti circuit inoshanda zvakachengeteka uye nemazvo. Dzinodzivirira kubva pakuwanda kwemagetsi, ma "short circuit", nezvimwe zvinokanganisa magetsi, izvo zvakakosha mukudzivirira tsaona dzemagetsi nenjodzi dzemoto.

Chimwe chezvakanakira zvikuru zveMCCBs kugona kwavo kubata mafungu emagetsi akawandisa. Akagadzirirwa kuchengetedza nekudzora macircuit ane simba rakawanda. Maindasitiri akadai sekugadzira, migodhi, mafuta negesi, uye kutakurwa kwezvinhu anovimba zvakanyanya neMCCBs kuchengetedza michina yavo yemagetsi yakakosha uye zvivakwa. Kugona kweMCCBs kubata mafungu emagetsi akawandisa uye kubvisa magetsi otomatiki kana paine kuwanda kana kutadza kunoita kuti MCCBs dzive dzinokosha mumaindasitiri aya.

Chimwe chinhu chakakosha cheMCCB ndechekuti iri nyore kuisa nekushandisa. Dzakakura uye dzinogona kubatanidzwa nyore nyore muma switchboard nema switchboard. Dhizaini yadzo yemodular inobvumira kuchinjika, zvichiita kuti dzikwanise kuchinjika zvichienderana nezvinodiwa zvakasiyana zvekuisa. Pamusoro pezvo, maMCCB anowanikwa mumhando dzakasiyana dzemagetsi, zvichiita kuti aenderane nemagetsi akasiyana-siyana. Kuiswa nyore uye kushandiswa kunoita kuti maMCCB ave sarudzo inozivikanwa yekuisa matsva uye kugadzirisa masisitimu emagetsi aripo.

Kururama uye kuvimbika kweMCCBs kunoita basa rakakosha mukuona kuti masisitimu emagetsi haachinji. MCCBs dzine nzira dzepamusoro dzekufamba dzinoona nekupindura zvikanganiso zvemagetsi nemazvo. Dzakashongedzerwa nemhando dzakasiyana dzemasensa nemasensa akadai sethermal, magnetic, electronic, nezvimwewo, zvinogona kuona mamiriro emagetsi asina kujairika. Kana paine dambudziko raonekwa, MCCB inodonha uye inodzima magetsi pakarepo, ichidzivirira kukuvara kwakawanda.

MaMCCB anobatsirawo kuvandudza mashandiro emagetsi. Nekudzivirira zvinobudirira kubva mukukundikana kwemagetsi uye kuwanda kwemagetsi, anodzivirira kugadzirwa kwekupisa kwakanyanya uye kutambisa magetsi zvisina kufanira. Izvi hazvingoderedzi njodzi yekukuvadzwa kwemidziyo chete, asiwo zvinovandudza kushandiswa kwesimba. Nekusimbiswa kuri kuramba kuchiita vanhu pakuchengetedza simba uye budiriro inoenderera mberi, kushandiswa kwema "molded case circuit breakers" kwakakosha kuti pave nechokwadi chekuti mashandiro anoshanda zvakanaka uye ane hushamwari kune zvakatipoteredza mumaindasitiri akasiyana.

Muchidimbu, kushandiswa kwakakura kwema "molded case circuit breakers" kwakavandudza zvakanyanya kuchengetedzeka, kuvimbika uye kushanda zvakanaka kwema "electrical circuit breakers" mumaindasitiri akasiyana-siyana. Kugona kwavo kubata ma "currents" akakwira, nyore kuisa, kuona zvikanganiso nemazvo, uye kubatsira mukushanda zvakanaka kwesimba kunoita kuti zvive zvinhu zvakakosha mukudzivirira nekudzora magetsi. Sezvo tekinoroji ichifambira mberi, ma "molded case circuit breakers" ari kuramba achichinja kuti asvike pazvinodiwa zve "electrical systems" dzemazuva ano. Sezvo maindasitiri achiramba achivimba ne "electrification" kuti ashande, basa reMCCB mukuona kuti ma "circuit" akachengeteka uye anoshanda zvakanaka richave rakakosha zvikuru.
