Muenzaniso weChigadzirwa
CJ: Kodhi yebhizinesi
M: Muchina wekupwanya dunhu wakaumbwa
1: Nhamba yeDhizaini
□:Yakayerwa current yefuremu
□:Kugona kuputsa kodhi/S inoratidza mhando yakajairika (S inogona kusiiwa)H inoratidza mhando yepamusoro
Cherechedza: Kune mhando ina dzedanda risina kusimba (N pole) dzechigadzirwa chezvikamu zvina. Danda risina kusimba rerudzi rweA harina chinhu chinogumbura chinodarika simba, rinogara richibatidzwa, uye haribatidzwe kana kudzima pamwe chete nedzimwe matanda matatu.
Pole isina simba remhando B haina chinhu chinodhonza magetsi chinodarika mwero, uye inobatidzwa kana kudzima pamwe chete nemamwe matanda matatu (pole isina simba rinobatidzwa risati radzimwa) Pole isina simba remhando C ine chinhu chinodhonza magetsi chinodarika mwero, uye inobatidzwa kana kudzima pamwe chete nemamwe matanda matatu (pole isina simba rinobatidzwa risati radzimwa) Pole isina simba remhando D ine chinhu chinodhonza magetsi chinodarika mwero, inogara ichibatidzwa uye haibatidzwe kana kudzima pamwe chete nemamwe matanda matatu.

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 kweMCCB kwakachinja zvachose nzira yekudzivirira macircuit. MCCB inoreva plastic case circuit breaker, iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwekushanda kwayo kwakanaka uye kuvimbika. Chinyorwa chino chichaongorora mashandisirwo akasiyana eMCCB uye kuti anogona sei kuva nemhedzisiro yakakosha pakuchengetedzwa kwemagetsi.
MaMCCB anoshandiswa zvakanyanya munzvimbo dzemaindasitiri uko kudzivirira macircuit kwakakosha. Macircuit breaker aya akagadzirwa kuti agone kubata ma currents akakwira uye anodzivirira kubva pakuwanda kwemagetsi, ma short circuit, nezvimwe zvinokanganisa magetsi. Chimwe chezvakanakira zvikuru zveMCCBs kugona kwavo kumisa kufamba kwemagetsi otomatiki kana paine chikanganiso, nokudaro vachidzivirira njodzi dzingangoitika dzakadai semoto kana kukuvara kwemidziyo inodhura.
Muzvivakwa zvemabhizinesi, maMCCB anoshandiswa kuchengetedza maseketi anobatidza masisitimu emwenje, masisitimu eHVAC, nezvimwe zvishandiso zvakakosha. Aya macircuit breaker anoita kuti kana paine chikanganiso, chikamu chakakanganiswa cheseketi chinobviswa pasina kukanganisa magetsi kune chimwe chivako. Kugona uku kuparadzanisa maseketi asina kunaka kunochengetedza nguva uye kudzivirira nguva yekusashanda zvisina kufanira munzvimbo yese.
Imwe nzira inokosha yeMCCB ndeyekushandisa simba rinogona kushandiswazve. Sezvo kudiwa kwesimba rekuchengetedza nharaunda kuri kuramba kuchiwedzera, ma "molded case circuit breakers" anoita basa rakakosha mukudzivirira masisitimu emagetsi emagetsi ezuva nema "wind turbines". Ma "circuit breakers" aya anoita kuti magetsi anogadzirwa aendeswe kugrid zvakachengeteka pasina kukanganisa michina kana vashandi.
Nekuda kwekuvakwa kwadzo kwakasimba uye kushanda kwadzo kwakavimbika, ma "molded case circuit breakers" anoshandiswawo zvakanyanya muindasitiri yemafuta negesi. MCCB ine basa rekuchengetedza ma "circuit" mumabasa akasiyana-siyana anosanganisira mapuratifomu ekunze, ma "refineries" uye kuisa mapombi. Ma "circuit breakers" aya akagadzirwa kuti agone kutsungirira mamiriro ekunze akaipisisa, zvichiita kuti masisitimu emagetsi akakosha arambe achishanda zvakachengeteka.
MCCB yakapindawo mubazi rezvekugara kuti ipe mhinduro dzinoshanda uye dzakavimbika dzekudzivirira macircuit epamba. Sezvo huwandu hwemidziyo nemasystem ari mumba huchiwedzera, njodzi yekukundikana kwemagetsi inowedzerawo. MCCB inodzivirira macircuit ekugara kubva pakuzara uye macircuit mapfupi, ichipa varidzi vemba rugare rwepfungwa uye kuwedzera kuchengetedzeka kwemagetsi.
Pamusoro pezvo, maMCCB anoshandiswa zvakanyanya munzvimbo dzedata kuchengetedza michina yakakosha uye masisitimu anotsigira tekinoroji yeruzivo. Aya macircuit breaker akakosha mukudzivirira kurasikirwa kwedata nekuda kwezvikanganiso zvemagetsi, kuve nechokwadi chekuti mashandiro asingadzoreki, uye kuchengetedza ruzivo rwakakosha rwakachengetwa mumasevha nemimwe michina yenetwork.
Muchidimbu, ma "molded case circuit breakers" anoshandiswa mumaindasitiri akasiyana-siyana, zvichiita kuti ave chikamu chakakosha chekudzivirira ma "circuit closures". Kugona kwawo kubata ma "currents" akakwira, kukanganisa kuyerera kwe "current" panguva yezvikanganiso, uye kuvaka kwakasimba kunoita kuti ave sarudzo inozivikanwa yekuona kuchengetedzeka kwemagetsi. Ingave munzvimbo dzemaindasitiri, zvivakwa zvemabhizinesi, kuisa simba rinogona kushandiswazve, nzvimbo dzemafuta negesi, dzimba dzekugara kana nzvimbo dzedata, MCCB yakaratidza kuva mhinduro yakavimbika uye inoshanda. Sezvo tekinoroji ichiramba ichifambira mberi, kushandiswa uye kukosha kwe "molded case circuit breakers" kuchawedzera, zvichiwedzera kuchengetedzwa kwemagetsi munzvimbo dzakasiyana-siyana.
