Imisebenzi, amacandelo kunye neenkcukacha ze-molded case circuit breakers

I. I-Plastic Case Circuit breaker (MCCB): Umsebenzi kunye nenkcazo yecandelo

Kwihlabathi lanamhlanje, imfuno yombane iyanda. Akufunekanga ukuba siqaphele nje ixabiso lombane ngamaxesha okunqongophala kwawo, kodwa kufuneka siqinisekise ukuba siwugcina ngendlela enengqiqo. Ukusombulula le ngxaki, ulawulo lwamandla luyafakelwa ukujonga okwangoku. Ngamanye amaxesha, ukulayisha ngaphezulu kunye neesekethe ezimfutshane zingonakalisa isiphaluka. I-low-voltage switchgear isetyenziselwa ukukhusela isiphaluka ngexesha leziganeko ezingaqinisekanga. Kweli nqaku, siza kutyhila ukuba yintoni i-breaker circuit breaker? Kwaye umsebenzi, amacandelo kunye neenkcukacha ze-molded case circuit breaker.

II. Yintoni i-MCCB

I-MCCB sisishunqulelo se-Plastiki-case circuit breaker esetyenziselwa ukukhusela iisekethe kunye namalungu azo kwi-overcurrent. Ukuba lo mbane awukho wodwa ngexesha elifanelekileyo, uya kubangela ukugqithiswa okanye isiphaluka esifutshane. Ezi zixhobo zinoluhlu olubanzi lwamaza, okwenza ukuba zifaneleke kwiinkqubo ezahlukeneyo zokukhusela iisekethe. Zihamba kwinqanaba langoku ukusuka kwi-15 amps ukuya kwi-1600 amps kwaye zingasetyenziswa kwizicelo eziphantsi kwe-voltage. Ungandwendwela iwebhusayithi yethu ku-www.ace-reare.com. Thenga i-Acereare Electric MCCB ngexabiso elifanelekileyo.

III. Umsebenzi we-plastic case circuit breaker

● Ukhuseleko lomthwalo omninzi
● Ukhuseleko lombane
● Vula uze uvale isiphaluka

I-MCCBS inokuqhawulwa ngokuzenzekelayo nangesandla kwaye isetyenziswe ngokubalulekileyo njengenye indlela kwii-microcircuit breakers kwiinkqubo ze-photovoltaic. I-breaker case circuit breaker ifakwe kwizindlu ezibunjiweyo ukukhusela uthuli, imvula, ioli kunye nezinye iikhemikhali.

Ekubeni ezi zixhobo zibamba imisinga ephezulu, zifuna ukulungiswa ngokufanelekileyo ngamaxesha athile, okunokwenziwa ngokucoca rhoqo, ukuthambisa, nokuvavanya.

IV. Khusela izixhobo zakho zombane

Zonke izixhobo zakho zombane zifuna umsinga ongatshintshiyo ukuze zisebenze kakuhle. Kubalulekile ukufaka i-MCCB okanye i-MCB ngokomthwalo wangoku. Ngokwenza njalo, iinkqubo zokulawula umatshini eziyinkimbinkimbi zinokukhuselwa ngokuhlukanisa ukunikezelwa kwamandla ngexesha lokungaphumeleli kombane.

V. Wuphephe umlilo

I-MCCB ehlangabezana nemigangatho yoshishino kwaye ikumgangatho olungileyo iyacetyiswa ukuqinisekisa ukhuseleko oluphezulu. Ezi zixhobo ze-electromagnetic zifumanisa iziphene xa kukho ukushukuma kwamandla okanye isekethe emfutshane ukuzikhusela emlilweni, ubushushu kunye nokudubula.

VI. Izixhobo kunye neenkcukacha ze-molded case circuit breakers

Amacandelo amane aphambili e-molded case circuit breaker ibandakanya
• Iqokobhe
• Indlela yokusebenza
• Inkqubo yokucima i-arc
• Isixhobo sokuhamba (uhambo olushushu okanye uhambo lwe-electromagnetic)

SHELL

Ikwabizwa ngokuba yindlu, ibonelela ngesithuba sezindlu ezigqunyiweyo ukuze kufakwe onke amacandelo e-breaker circuit. Yenziwe nge-resin edibeneyo ye-thermosetting (i-DMC mass material) okanye i-polyester yeglasi (i-injection iinxalenye ezibunjiweyo) ukunika amandla aphezulu e-dielectric kuyilo lwayo oluhlangeneyo. Eli gama linikezelwa ngokohlobo kunye nobukhulu becala elibunjiweyo kwaye lisetyenziselwa ukuchaza iimpawu ze-breaker circuit (ubuninzi be-voltage kunye ne-rated current).

Indlela yokusebenza

Ukuvulwa nokuvalwa koqhagamshelwano kufezwa yindlela yokusebenza. Isantya apho abafowunelwa bavulwa kwaye bavalwe kuxhomekeke kwindlela isiphatho esihamba ngayo. Ukuba unxibelelwano luhamba, uya kukwazi ukubona ukuba isibambo sikwindawo ephakathi. Ukuba i-breaker circuit ikwi-position, akunakwenzeka ukuyenza uhambo, olubizwa ngokuba "luhambo oluzenzekelayo".

Xa i-breaker circuit ikhutshiwe, oko kukuthi, ukuba isibambo sikwindawo ephakathi, kufuneka iqale ihanjiswe kwindawo yokuvala kwaye emva koko ibekwe kwindawo. Kwiimeko apho abaphuli beesekethe bafakwe kwiqela (njenge-switchboard), izikhundla ezahlukeneyo zokubamba zinceda ukufumana isiphaluka esiphosakeleyo.
Ngokuqhelekileyo, ngaphambi kokuba i-breaker circuit ihambe kumzi-mveliso, siya kufumanisa ukuvulwa kunye nokuvalwa kwe-breaker circuit overload kunye nesiphaluka esifutshane kwisigaba esisodwa kunye neendlela ezimbini zokubeka iliso ukuba ngaba i-breaker circuit ikhutshiwe ngaphakathi kwexabiso loluhlu ukuze kuqinisekiswe ukuba ukhuseleko lwe-breaker circuit ekusetyenzisweni kwangempela kwendawo.

Inkqubo yokucima i-arc

I-Arc interrupter: I-arcing yenzeka xa i-breaker circuit iphazamisa umsinga. Umsebenzi wesiphazamisi kukuvalela kunye nokwahlula i-arc, ngaloo ndlela uyicima. Igumbi lokucima i-arc lifakwe kwibhokisi ye-insulated ephezulu, eyona nto iqulethwe ngamaqhekeza egridi yokucima i-arc, edlala indima ebalulekileyo ekuqalisweni kwe-arc kunye nokucima i-arc kwimveliso yombane ephantsi. Xa umnxibelelwano uhlukana ngenxa yokuphazamiseka, ikhoyo ngoku ejikelezayo kwingingqi ye-ionized yoqhagamshelwano idala i-magnetic field ejikeleze i-arc kunye ne-interrupter.

Imigca yemagnethi eyenziwe malunga ne-arc iqhuba i-arc kwipleyiti yentsimbi. Emva koko irhasi ihlanjululwa, ihlulwe yi-arc, ivumela ukuba ipholile. I-MCCBS eqhelekileyo isebenzisa i-linear current ngoqhagamshelwano, oluthi, phantsi kweemeko ezimfutshane zesekethe, idale amandla amancinci okuqhuma, okunceda ukuvula umnxibelelwano.

Uninzi lwesenzo sokuvula senziwa ngamandla omatshini agcinwe kwindlela yokukhwela ngokwayo. Oku kungenxa yokuba umsinga kubo bobabini abafowunelwa uhamba ngendlela efanayo ngqo.

Isixhobo sohambo (uhambo olushushu okanye lwe-electromagnetic)

Isixhobo sohambo bubuchopho bomaphuli wesekethe. Umsebenzi ophambili wesixhobo sokukhubeka kukuhamba kwindlela yokusebenza kwimeko yesekethe emfutshane okanye ukulayisha ngokuqhubekayo. Izaphuli zesekethe zokungunda eziqhelekileyo zisebenzisa izixhobo zokukhwela i-electromechanical. Izaphuli zesekethe zikhuselwe ngokudibanisa izixhobo ezibuthathaka kwiqondo lobushushu kunye nezixhobo zohambo lwe-elektroniki, ezinokuthi ngoku zibonelele ngokhuseleko oluphezulu kunye nokubeka iliso. Uninzi lweesekethe zesekethe ezibunjiweyo zisebenzisa enye okanye ngaphezulu izinto ezahlukeneyo zohambo ukubonelela ngokhuseleko lwesekethe kwiinkqubo ezahlukeneyo. Ezi zinto zikhubekayo zikhusela ukugqithiswa kwe-thermal, iisekethe ezimfutshane kunye nokungaphumeleli komhlaba we-arc.

I-MCCBS eqhelekileyo ibonelela ngezixhobo zokukhwela ze-electromechanical ezisisigxina okanye ezitshintshayo. Ukuba i-fixed trip circuit breaker ifuna ireyithingi entsha yohambo, i-circuit breaker iyonke kufuneka itshintshwe. Izixhobo zohambo ezitshintshiswayo zikwabizwa ngokuba ziiplagi ezilinganisiweyo. Abanye abaphuli beesekethe babonelela ngokutshintshiselana phakathi kwezixhobo zohambo lwe-electromechanical kunye ne-elektroniki kwisakhelo esifanayo.

Ukuqinisekisa ukusebenza kakuhle kwe-MCCB, ukugcinwa rhoqo kufuneka kuqhutywe, kubandakanywa nokuhlolwa okubonakalayo, ukucocwa kunye nokuvavanya.

VII. Ukusetyenziswa kwe-molded case circuit breaker

I-MCCB yenzelwe ukuphatha imisinga ephezulu kwaye isetyenziswa ngokubanzi kwimisebenzi enzima efana nohambo oluhlengahlengiswayo Izicwangciso zezicelo eziphantsi zangoku, ukukhuselwa kweemoto, ukukhuselwa kweebhanki ze-capacitor, i-welders, ukukhuselwa kweejeneretha kunye ne-feeders.
