Isihloko: Yazi Umehluko PhakathiAma-Miniature Circuit BreakersfuthiAma-Circuit Breaker wekesi elibunjiwe
Izinqamuli zesekethe ziyingxenye ebalulekile yesistimu kagesi yesakhiwo.Zisiza ukuvikela ikhaya lakho, ihhovisi noma impahla yezentengiselwano ekulayishweni kukagesi ngokweqile namasekethe amafushane.Ama-circuit breaker amabili asetshenziswa kakhulu yi-miniature circuit breaker (I-MCB) kanye ne-circuit breaker yecala elibunjiwe (I-MCCB).Nakuba zombili zifeza injongo efanayo, kunomehluko othile phakathi kwazo.Kule bhulogi, sizohlola lo mehluko.
1. Usayizi kanye nokusetshenziswa
Umehluko omkhulu phakathiI-MCBfuthiI-MCCBubukhulu bazo.Njengoba igama liphakamisa, ama-MCB mancane ngosayizi futhi asetshenziswa ezinhlelweni zamanje eziphansi afika ku-125 amps.Zivame ukusetshenziswa ezindaweni zokuhlala kanye nezicelo zokuhweba ezincane.Ngakolunye uhlangothi, ama-MCCB makhulu futhi angakwazi ukuphatha imithwalo yamanje ephezulu efika ku-5000 amps.Ngokuvamile zisetshenziswa ezimbonini nasezinhlelweni zezentengiselwano ezidinga amanani aphezulu wamandla.
2. Iqinile futhi ihlala isikhathi eside
I-MCCB inamandla futhi ihlala isikhathi eside kune-MCB.Bangakwazi ukubhekana nokucindezeleka kukagesi okwengeziwe futhi zenzelwe ukumelana nezindawo ezinokhahlo.Ama-MCCBsngokuvamile zenziwe ngezinto ezinamandla ezifana ne-ceramic noma ipulasitiki ebunjiwe kuneAma-MCBs, ngokuvamile ezenziwe ngendlu yepulasitiki.Ama-MCB adizayinelwe ukusetshenziswa ezindaweni ezinokhahlo oluncane futhi akufanele avezwe ezintweni ezigqwala kakhulu noma amazinga okushisa adlulele.
3. Indlela yohambo
Kokubili ama-MCB kanyeAma-MCCBsziklanyelwe ukukhubeka uma i-current yeqa umkhawulo othile.Nokho, izindlela abazisebenzisayo ukuze bahambe zihlukile.I-MCB inomshini wohambo ozibuthe oshisayo.Umshini usebenzisa umugqa we-bimetal oshisa futhi ogobile lapho i-current idlula umkhawulo, okubangela ukuba isinqamuli sesekethe sihambe.I-MCCB inomshini wohambo we-elekthronikhi esebenzisa i-microprocessor ukuze ihlaziye ukugeleza kwamanje.Uma i-current idlula i-threshold, i-microprocessor ithumela isignali ku-circuit breaker ukuze ihambe.
4. Izindleko
Ama-MCBsngokuvamile zibiza kancane kuneAma-MCCBs.Lokhu kungenxa yokuthi zilula ekwakhiweni futhi zenziwe ngezinto ezishibhile.Futhi aqinile kancane kunama-MCCB futhi anomthamo ophansi wokuthwala wamanje.Ama-MCCB abiza kakhulu ngenxa yomklamo wawo oyinkimbinkimbi nezinto ezisetshenziswayo, kodwa ahlala isikhathi eside futhi angakwazi ukusingatha imithwalo yamanje ephakeme.
5. Isondlo
Ukugcinwa okudingekayo kuma-MCB kanyeAma-MCCBsyehluke kakhulu.I-MCB ilula ekwakhiweni kwayo futhi ayidingi ukulungiswa okuningi.Kudingeka zihlolwe njalo nguchwepheshe kagesi futhi zishintshwe uma zinephutha.Ngakolunye uhlangothi, ama-MCCB, adinga ukunakekelwa okwengeziwe, njengokuhlolwa okuvamile kwamayunithi ohambo lwe-elekthronikhi, angase angabe esasebenza ngokuhamba kwesikhathi futhi adinga ukushintshwa.
Kafushane, i-MCB kanyeI-MCCBabe nomsebenzi ofanayo, okuwukuvikela uhlelo lukagesi ekulayishweni ngokweqile kanye nokujikeleza okufushane.Nokho, njengoba singabona, kukhona umehluko phakathi kwalokhu okubili.Ama-MCB mancane, ahlala isikhathi eside futhi ayabiza kancane, kuyilaphoAma-MCCBszinamandla, zihlala isikhathi eside futhi zibiza kakhulu.Isicelo kanye nezidingo zamanje yizinto ezibalulekile okufanele uzicabangele lapho ukhetha phakathi kwalokhu kokubili.
