KunzwisisaMCCB Circuit Breakers: Gwaro Rakazara
Ma "molded case circuit breakers" (MCCBs) zvinhu zvakakosha mumagetsi, zvichidzivirira ma "circuit" kubva pakuwanda kwemagetsi uye ma "short circuit". Sezvo kudiwa kwe "electrical systems" dzakavimbika uye dzinoshanda kuri kuramba kuchikura, kunzwisisa mashandiro nemashandisirwo e "MCCBs" kuri kuramba kuchikosha kune vese nyanzvi nevanofarira mainjiniya emagetsi.
Chii chinonzi MCCB circuit breaker?
Chinoputika circuit breaker (MCCB) chishandiso chemagetsi chinodzima kufamba kwemagetsi mucircuit kana chaona chimwe chinhu chisina kujairika, senge overload kana short circuit. Kusiyana nemafuse echinyakare, ayo anofanira kutsiviwa mushure mekunge aputika, maMCCB anogona kudzoserwa patsva mushure mekugumburwa, zvichiita kuti ave mhinduro iri nyore uye isingadhuri yekudzivirira circuit.
Ma "molded case circuit breakers" (MCCBs) anowanikwa mumhando dzakasiyana-siyana dze "current ratings", kazhinji kubva pa16A kusvika 2500A, uye akakodzera kushandiswa kwakasiyana-siyana kubva munzvimbo dzekugara kusvika kumaindasitiri. Ma "molded case circuit breakers" avo akasimba uye anopa dziviriro inoshanda kubva kuzvinhu zvakatipoteredza.
Zvinhu zvikuru zveMCCB circuit breaker
1. Dziviriro Yekuwedzeredza: Ma "molded case circuit breakers" ane "thermistor" yekuona kuwanda kwemagetsi. Kana magetsi adarika muganho wakatarwa, "thermistor" inopisa uye inodonha, zvichidzivirira kukuvara kwemagetsi.
2. Dziviriro yepfupi: Kana divi repfupi rikaitika, muchina wekugadzirisa divi remagetsi (MCCB) unoshandisa electromagnetic mechanism kubvisa divi remagetsi ipapo ipapo. Mhinduro iyi yekukurumidza inokosha mukudzivirira kukuvara kukuru kwemidziyo uye kuderedza njodzi yekubvira kwemoto.
3. Zvigadziriso Zvinogadziriswa: MaMCCB mazhinji anouya nezvirongwa zvekudzivirira overload zvinogadziriswa, zvichibvumira vashandisi kugadzirisa current yerwendo kuti ienderane nezvinodiwa zvesystem yavo yemagetsi.
4. Matanda Akawanda: MaMCCB anowanikwa mumhando dzakasiyana-siyana, kusanganisira magadzirirwo ematanda maviri, matanda maviri, uye matanda matatu, kuti akwane mashandisirwo akasiyana.
5. Mabasa akabatanidzwa: Mamwe maMCCB epamusoro ane zvimwe zvinhu zvakaita sekudzivirira zvikanganiso zvepasi, kugona kutaurirana, uye masisitimu ekutarisa, nokudaro zvichivandudza mashandiro avo nekuchengetedzeka.
Kushandiswa kweMCCB circuit breaker
Ma MCCB circuit breakers anoshandiswa zvakanyanya muminda yakasiyana-siyana, kusanganisira:
- Mashandisirwo Emaindasitiri: Mumafekitori ekugadzira, maMCCB anodzivirira michina nemidziyo kubva kumatambudziko emagetsi, zvichiita kuti mashandiro arambe achienderera mberi uye akachengeteka.
- Zvivako zveMabhizimisi: Muzvivako zvemahofisi nezvitoro, maMCCB anodzivirira mapaneru emagetsi nemabhodhi ekuparadzira, zvichipa dziviriro yakavimbika yemwenje, masisitimu eHVAC, uye mimwe mitoro yemagetsi.
- Kushandiswa Kwedzimba: Varidzi vedzimba vanogona kubatsirwa neMCCBs mumapanera avo emagetsi kuti vape dziviriro yakawedzerwa yemidziyo yemumba uye kuderedza njodzi yemoto wemagetsi.
Mabhenefiti ekushandisa maMCCB circuit breakers
1. Kuvimbika: MCCB dzinozivikanwa nekuvimbika kwadzo uye kugara kwenguva refu, zvichiita kuti dzive sarudzo yepamusoro yekushandisa zvakakosha apo nguva yekushanda inodhura.
2. Zviri nyore kuchengetedza: Kana tichienzanisa nemafuse echinyakare, MCCB ine kugona kudzoreredza mushure mekugumburwa, izvo zvinogona kuderedza mari yekugadzirisa uye nguva yekuzorora.
3. Kuchengetedzeka: Nekupa dziviriro inoshanda yekuwandisa uye yepfupi, maMCCB anovandudza kuchengetedzeka kwese kwemagetsi.
4. Kuchinja-chinja: Mhando dzakasiyana dzemagadzirirwo azvino uno uye magadzirirwo anoita kuti maMCCB akwanise kushandiswa zvakasiyana-siyana, kubva kumasekete madiki ekugara kusvika kumasisitimu makuru eindasitiri.
Muchidimbu
Zvichitaurwa zviri nyore, ma "molded case circuit breakers" (MCCBs) anoita basa rakakosha mumagetsi emazuva ano, achipa dziviriro yakakosha yemagetsi uye ma "short-circuit". Kuvimbika kwawo, nyore kugadzirisa, uye kushanduka-shanduka kunoita kuti ave zvinhu zvakakosha mukushandiswa kwedzimba nemaindasitiri. Sezvo tekinoroji ichiramba ichichinja, kunzwisisa nekushandisa maMCCB kuchawedzera kukosha kuitira kuti magetsi ave akachengeteka uye anoshanda zvakanaka kwemakore anotevera. Ungave uri mainjiniya wemagetsi, muvaki, kana muridzi wemba, kujairana nemaMCCBs kwakakosha pakutarisira nekuchengetedza magetsi zvinobudirira.
