Yini inzuzo ye-MCB

Ama-Breaker Circuiture Circuit (MCBS)Idizayini ye-VC VOLTAGES ilungele izinhlelo zokusebenza kwezokuxhumana kanye ne-Photovoltaic (PV) DC Systems. Ngokugxila okuthile ekusebenzeni nasekuthembekeni, la ma-MCBS anikela ngezinzuzo ezahlukahlukene, ekhuluma nezinselelo ezihlukile ezibangelwa izinhlelo eziqondile zamanje. Ukusuka kwi-wiring eyenziwe lula kuya kumandla we-voltage alinganiswe kakhulu, izici zawo zibhekelela izidingo eziqondile zobuchwepheshe besimanje, ukuzenza zibaluleke kakhulu ekuqinisekiseni ukuphepha nokusebenza kahle. Kulesi sihloko, singena ezinzuzweni eziningi ezibeka la malungu eMCBS njengabadlali abasezingeni eliphakeme bendawo eguqukayo yobunjiniyela bakagesi.

Idizayini ekhethekile yezinhlelo zokusebenza ze-DC

Le khasiI-JCB3-63DC Breaker BreakerIvelele ngomklamo wayo ofanelekile, eyakhiwe ngokusobala yezinhlelo zokusebenza ze-DC. Lokhu kusebenza kuqinisekisa ukusebenza kahle kanye nokuphepha ezindaweni lapho kuvela khona okujwayelekile. Lo mklamo okhethekile uwukuvuselela ukuguqulwa kwe-Breaker Breaker, ukuzulazula ngaphandle komthungo ezinkampanini zezindawo ze-DC. Kubandakanya izici ezinjenge-non-polarity kanye ne-wiring elula, ukuqinisekisa inqubo yokufaka mahhala. Amandla kagesi alinganiselwe aphezulu afinyelela ku-1000V DC afakazele amandla awo aqinile, isici esibalulekile ekusingatheni izimfuno zobuchwepheshe besimanje. I-JCB3-63DC Breaker Breaker ayihlangani nje namazinga embonini; Kuyababeka, kukhombisa ukuzibophezela okungafanele ekusebenzeni kahle nasekufezeni. Idizayini yayo, ihlelwe kahle ngelanga, i-PV, isitoreji samandla, kanye nezinhlelo ezahlukahlukene ze-DC, igcizelela isikhundla sayo njengetshe legumbi lokuthuthukisa amasistimu kagesi.

I-non-polarity kanye ne-wiring elula

Enye yezici ezidweshunayo ze-MCB zingezona ze-polarity zazo ezenza lula inqubo yokuqwayiza. Lesi sici asigcini nje ngokuthuthukisa ubungani - ubungani kodwa futhi sinomthelela ekunciphiseni kwephutha ngesikhathi sokufakwa.

Amandla alinganiselwe alinganiselwe

Ngomzimba olinganiselwe ofinyelela ku-1000V DC, la malungu e-MCB akhombisa amandla amakhulu, abenze bakwazi ukuphatha izidingo zezinhlelo ze-DC eziphakeme ze-DC ezitholakala amanethiwekhi okuxhumana kanye nokufakwa kwe-PV.

Umthamo wokushintsha okuqinile

Ukusebenza ngaphakathi kwamapharamitha we-IEC / EN 609477-2, la ma-MCBS aqhayisa umthamo olinganiswe kakhulu we-6 ka. Lesi sici siqinisekisa ukuthi i-Breaker yesekethe ingaphatha ngokuthembekile imithwalo ehlukahlukene futhi iphazamise ngempumelelo ukugeleza kwamanje ngesikhathi sephutha.

I-Insulation Votage kanye ne-Imputerse

I-Insulation Votage (UI) ye-1000V kanye ne-Imputerse yokulwa ne-Imputerse yokulwa (i-UIMP) ye-4000V igcizelela amandla we-MCB okumelana nengcindezi kagesi, enikeza ungqimba owengeziwe wokuqina ezimeni zokusebenza ezahlukahlukene.

Isigaba 3

Ihlukaniswe njengedivaysi e-3 yamanje yokukhawulela i-3 Class 3, la ma-MCBS Excel ngokunciphisa ukulimala okungaba khona uma kwenzeka kuba nephutha. Lokhu kunamandla kubalulekile ekuvikeleni amadivaysi aphansi kanye nokugcina ubuqotho bohlelo kagesi.

Khetha i-Fuse-up fuse

Ifakwe nge-fuse ye-back-up efaka ukukhethwa okuphezulu, la ma-MCBs aqinisekisa amandla aphansi avumela amandla. Lokhu akupheleli kuphela ukuvikelwa kohlelo kodwa futhi kunomthelela ekuthembekeni okuphelele kokusetha kukagesi.

Isikhombi sokuxhumana

Isikhombi sokuxhumana esibomvu esisebenziseka kalula sinikezela ngesiginali ebonakalayo ebonakalayo, okukuvumela ukuthi uqaphe kalula isimo sekhefu. Lesi sici esilula kodwa esisebenzayo singeza ungqimba olungeziwe lokusebenziseka kalula kwabasebenza.

Uhla olubanzi lwe-Custom Currents

Lawa ma-MCBS ahlalisa uhla oluhlukahlukene lwe-Custom Currents, ngezinketho ezifinyelela ku-63a. Lokhu kuvumelana nalokhu kubenza bakwazi ukufeza izidingo zomthwalo ezihlukile zezinhlelo zokusebenza ezahlukahlukene, zingeza ukuguquguquka kokusebenza kwazo.

Ukucushwa kwezindlela eziguqulelayo

Kutholakala ku-1 Pole, 2 Pole, 3 Pole, kanye no-4 ukumiswa kwezingodo, la ma-MCBS anakekela ukusetha okuhlukahlukene kohlelo. Lokhu kuguquguquka kusebenza ngokuvumelanisa nezidingo ezithile zokufakwa kukagesi okuhlukile.

Izilinganiso zeVoltage zezigxobo ezihlukile

Izilinganiso ze-voltage ezihlanganisiwe zokucushwa okuhlukile kwe-pole

Ukuhambisana namabhasi ajwayelekile

I-MCB Breaker yenzelwe ukuhlanganiswa komthungo nge-PIN kanye neFork Type Busbars Balbars ejwayelekile. Lokhu kuhambelana kuhambelana nenqubo yokufaka futhi kusiza ukufakwa kwabo kuma-setups akhona kagesi.

Yakhelwe isitoreji selanga kanye namandla

Ukuguquguquka kwamanye amazwe kwensimbi ye-MCB kuqokonyiswa futhi ngumklamo wawo ocacile we-solar, PV, isitoreji samandla, nezinye izinhlelo ze-DC. Njengoba izwe lifaka imithombo yamandla evuselelekayo, laba baphula izifunda bavela njengezakhi ezibalulekile ekuqinisekiseni ukuthembeka nokuphepha kwalezo zinhlelo.

Umunyu ongaphansi

Izinzuzo zeI-Miniature Circuit Breaker (MCB)inwebeka kude kakhulu design yabo ekhethekile. Ukusuka kwizicelo ezikhethekile ze-DC ezicini zabo ezisebenziseka kalula, la ma-MCB abeka amazinga amasha ngokuphepha nasekusebenzeni kahle. Njengoba ubuchwepheshe buqhubeka buqhubekisela phambili, abaphukileyo bezesekeli bangama-stalwarts, bavikele ubuqotho bezinhlelo zokuxhumana nokufakwa kwe-PV ngamakhono abo angenakuqhathaniswa. Umshado wokwenziwa okusha nokwethembeka kulawa malungu eMCBS uwagcina njengempahla ebaluleke kakhulu endaweni ekhula njalo yobunjiniyela bakagesi.
