Amakhethini Ababunjiwe Abaphula Amandla: Izici ezibalulekile kanye nezicelo

Amakhesi abunjiwe amakhethini amakhethini (MCCBS)Izakhi ezihlanganayo ezinhlelweni zokusabalalisa kagesi, zenzelwe ukuhlinzeka ukuvikela ngokweqile nokuhlukaniswa kwezicelo ezahlukahlukene. Ngentuthuko kwezobuchwepheshe kanye namazinga okuphepha, iqhaza lama-MCCB livele, libenze babalulekile ukuthola imibuthano kagesi ezindlini zokuhlala, ezentengiso nasezimboni. Le ndatshana idlulela kwizici, izinhlobo, izinhlelo zokusebenza, kanye nokubaluleka kwabaphuluki bezifunda, baqokomisa ikakhulukaziIsitifiketi se-TUV High 3p M1 63A-1250A hlobo MCCB kanye ne-250A MCCB.

Yini aI-Consed Case Breaker Breaker (MCCB)?

I-Poilded Case Breaker Breaker iyithuluzi le-elektrolokhethi eliphazamisa ukuhamba kwezikhathi zikagesi zamanje uma kulayishwa ngokweqile noma izimo ezifushane zesekethe. Ngokungafani nama-fuse wendabuko, adinga ukushintshwa ngemuva kwephutha, ama-MCCB angasetwa kabusha ngemuva kokukhipha, enikeza isixazululo esisebenza kahle futhi esibizayo sokuvikelwa kwesifunda. "Icala elibunjiwe" libhekisela ezindlini zepulasitiki ezifaka umfutho, zinikezela ukuqina kanye nokufakelwa.

Izici ezibalulekile zeMCCBS

Amakhekhe amacala abunjiwe (ama-MCCBs) ayizinto ezibalulekile ezinhlelweni zikagesi, eklanyelwe ukuhlinzeka ukuvikela ngokugcwele kanye nezimo ezifushane zesekethe. Nazi ezinye zezici ezibalulekile zeMCCBS:

• Izilinganiso Zamanje: Ama-MCCB ayatholakala ezilinganisweni ezahlukahlukene zamanje, ngokuvamile ezisukela ku-16a kuya ku-3200a. Uchungechunge lwesitifiketi se-TUV High 3p M1, ngokwesibonelo, kubhekise ezilinganisweni zamanje ezivela ku-63a ziye ku-1250a, zilenze zilungele izinhlelo zokusebenza ezahlukahlukene.
• Ezintathu-pole izinketho ezine-4: I-MCCBS ingahle ilungiselelwe njengezithelo ezintathu (3p) noma amadivaysi amane we-pole (4p), avumela uhlelo lwesigaba esisodwa noma lwesigaba ezintathu. Ukucushwa kwezintathu - kuvame ukusetshenziswa ezinhlelweni ezintathu zesigaba, kuyilapho ukucushwa kwezine-amane kunezela isigxobo esingathathi hlangothi ngemithwalo enokulinganisela.
• Izilungiselelo zohambo eziguqukayo: Ama-MCCBS avame ukufaka izilungiselelo eziguqukayo zokuvundwa kwe-thermal kanye nama-magnetic, avumela abasebenzisi ukuthi benze ngokwezifiso ukuvikela okususelwa kwizidingo ezithile zohlelo lokusebenza.
• Idizayini ehlanganisiwe: Ukuklanywa kwamacala abunjiwe kunomthelela ekuhlanganeni kwama-MCCB, lula ukufakwa ezindaweni ezilinganiselwe ngaphandle kokuyekethisa ukusebenza.
• Ukwethembeka nokuqina: Izinto ezisezingeni eliphakeme ezisetshenziselwa ukwakhiwa kwama-MCCBS ziqinisekisa ukuthembeka kwesikhathi eside, zibenze balungele izindawo ezifunwa kwezimboni.

Amacala abunjiwe asebenza kanjani

IMCCBS isebenza emgomeni wokuthola izimo ezingaphezulu kwama-armal kanye namazibuthe.

• Umshini wokushisa: Lesi sici sithola izimo ezilayishwe ngokweqile, lapho okwamanje kudlula umthamo olinganiselwe isikhathi eside. Into ye-thermal ishisa futhi igobe umucu we-bimetallic, kubangele ukubaphula umjikelezo.
• Umshini wamandla kazibuthe: Le ndlela iphendula ezimweni ezifushane zesekethe, lapho kwanda khona ukwenyuka kwamanje ngokuzumayo nangensali. I-magnetic coil yakha amandla kazibuthe adonsela i-plunger, ngokushesha aqhakaza umfutho wesifunda.

Izicelo ze-Solded Case Circuit Breakers

I-MCCBS iyaguquguquka futhi ingatholakala ezinhlobonhlobo zezicelo emikhakheni ehlukahlukene, kufaka phakathi:

• Izicelo zezimboni: I-MCCBS isetshenziswa kakhulu ekukhiqizeni izitshalo, lapho zivikela khona ama-motors, ama-transformers, kanye namabhodi okusabalalisa kusuka kumasekethe angaphezulu nangemifushane.
• Izakhiwo Zentengiso: Kuzilungiselelo zentengiso ezinjengamahhovisi, izitolo ezinkulu zezitolo, namahhotela, ama-MCCBS avikela amaphaneli kagesi nemishini, ukuqinisekisa ukuphepha kanye nokuhambisana namakhodi kagesi.
• Ukufakwa Kwezindawo Zokuhlala: Ama-MCCB asetshenziswa futhi ezakhiweni zokuhlala, ikakhulukazi izinhlelo zikagesi eziphezulu, enikeza ukuvikela izinto zasekhaya nasezintanjeni.
• Izinhlelo zamandla avuselelekayo: Ngokukhuphuka kwamandla avuselelekayo, ama-MCCB asemqoka ekufakweni kwamandla elanga kanye nezinhlelo zamandla omoya, ukuvikela ama-inverters kanye nokuxhunywa ngogesi.
• Izikhungo zedatha: Ezikhungweni zedatha lapho ukusebenza okuqhubekayo kubucayi, ama-MCCBS aqinisekisa ukusatshalaliswa kwamandla okuthembekile nokuvikelwa kwamaseva nemishini yokuxhumana.

Ukubaluleka kwesitifiketi se-TUV High 3p M1 63a-1250A hlobo mccb

Isitifiketi se-TUV esiphakeme se-3p M1 se-MCCBS, ekalwe phakathi kuka-63a kuya ku-1250A, samukelwa ngekhwalithi yayo ephezulu nokwethembeka. Isitifiketi se-TUV sibonisa ukuthi la ma-MCCB aqala ukuhlola okunzima futhi ahlangabezane namazinga okuphepha aphesheya, ahlinzeka abasebenzisi ngokuqiniseka ekusebenzeni kwawo.

• Ukuphepha okuthuthukileIsitifiketi se-TUV siqinisekisa ukuthi i-MCCB ihlangabezana nezidingo eziqinile zokuphepha, inciphisa ubungozi bezingozi zikagesi.
• Ukusebenza kwamandla: Izakhi eziseqophelweni eliphezulu ezisetshenziswa kuma-MCCCS aqinisekiswe ama-TUV zineqhaza ekusebenzeni kwamandla, ukunciphisa ukulahleka kwamandla kanye nokwenza ngcono ukusebenza kohlelo lonke.
• Isikhathi eside sokuphila: Ngokwakhiwa okuhlala isikhathi eside nokusebenza okuthembekile, i-MCCCS eqinisekisiwe ye-TUV inikeza isikhathi sokuphila eside, inciphisa isidingo sokufakwa kabusha kanye nokulungiswa okujwayelekile.

Ukuqonda 250A MCCB

I-250A MCCB iyisilinganiso esithile phakathi komndeni wesekethe umjikelezo wokubumba, oklanyelwe izinhlelo zokusebenza ezidinga ukuvikelwa kwamanje.

• Ububanzi: I-250A MCCB iyasebenziseka kalula futhi ingasetshenziswa ezinhlelweni ezahlukahlukene, kusuka ekusethweni kwezimboni ezimbalwa ezakhiweni ezinkulu zentengiso, zinikeza ukuvikela okusebenzayo.
• Izilungiselelo eziguqukayo: Abasebenzisi bangenza ngezifiso izilungiselelo zohambo ze-250A MCCB, okuvumela ukuguquguquka ekuphatheni imithwalo ehlukene kanye nokuqinisekisa ukuvikelwa okuphezulu.
• Idizayini ehlanganisiwe: Njengamanye ama-MCCBS, inguqulo engama-250a inembatho ye-compact, okwenza ilungele ukufakwa lapho isikhala siyisithiyo.

Izinzuzo zokusebenzisa amakhefu abunjiwe amacala aphuka

AbakwaBelicreker Clearte Breakers (MCCBS) banikela ngezinzuzo eziningana ezibenza babe yikhethelo elithandwayo lokuvikela amasekethe kagesi ezisetshenzisweni ezahlukahlukene. Nazi izinzuzo ezisemqoka zokusebenzisa i-MCCBS:

Ukuvikelwa okwengeziwe

I-MCCBS ihlinzeka ukuvikela okuthembekile ekugcwalisweni ngokweqile kanye nemibuthano emifushane. Bangakwazi ukubona okwedlulele kokujikeleza nokuhamba umjikelezo, ukuvimbela ukulimala kwemishini kagesi futhi kunciphise ubungozi bezingozi zomlilo.

Ukuphihlazeka

Ngokungafani nama-fuse wendabuko, okumele athathelwe indawo ngemuva kwephutha, ama-MCCB angasetwa kabusha ngemuva kokuphakama. Lesi sici asigcini nje ngokunciphisa isikhathi sokuphumula kodwa futhi sinciphisa izindleko zokubuyiselwa kanye nemizamo yesondlo.

Izilungiselelo eziguqukayo

Ama-MCCB amaningi eza nezilungiselelo zohambo eziguqukayo, evumela abasebenzisi ukuthi basebenzise ngokwezifiso umkhawulo wohambo lokushisa nokwezibuthe ngokwezidingo ezithile zohlelo lwazo. Lokhu kuguquguquka kusiza ekuphatheni izimo ezihlukile zomthwalo ngempumelelo.

Idizayini ehlanganisiwe

I-MCCBS yakhelwe nge-compact footprint, ibenze balungele ukufakwa ezindaweni ezilinganiselwe. Usayizi wabo uvumela ukuhlanganiswa okulula kumaphaneli kagesi namabhodi okusabalalisa.

Ukuqina Okuphezulu

Ama-MCCBS ayakhiwa kusuka ezintweni ezisezingeni eliphakeme, ukuhlinzeka ukuqina kanye nesikhathi eside sokuphila isikhathi eside. Bayakwazi ukubekezelela izimo ezinzima zemvelo, ukuzenza zilungele izinhlelo zokusebenza zezimboni nezangaphandle.

Ukuhambisana Namazinga

Ama-MCCB enzelwe ukufeza amazinga okuphepha namazwe omhlaba, aqinisekise ukuthi ahlinzeka ngokuvikelwa okuthembekile futhi ahambisane namakhodi kagesi. Lokhu kuthobela kubalulekile ekufakweni kwezilungiselelo zezentengiso nezimboni.

Ukugcina

Abaphukileyo besifunda ababunjiwe bayizakhi ezibalulekile ezinhlelweni zesimanje zikagesi, zihlinzeka ngokuvikelwa okuthembekile okuphezulu kwezicelo ezahlukahlukene. Ngezinto ezifana nezilungiselelo zohambo eziguqukayo, ukwakhiwa okuhlangene, kanye nokuhambisana namazinga okuphepha aphesheya okufana nesitifiketi se-TUV, iMcCCBS efana neIsitifiketi se-TUV High 3p M1 63A-1250A hlobo MCCB kanye ne-250A MCCB zibalulekile ekuqinisekiseni ukuphepha kanye nokusebenza kahle kokufakwa kukagesi. Njengoba ubuchwepheshe buthuthuka, ukubaluleka kokukhetha amadivaysi okuvikela umjikelezo afanele kuzoqhubeka nokukhula, okwenza kube balulekile ukuthi abasebenzisi baqonde ukusebenza kanye nezinzuzo zabaphuluki bemijikelezo ebunjiwe.
