Hagaha Waxqabadka leh ee Jabiya Kiiska Wareegga ah

Waa maxay MCCB?

MCCB-kiis wareeg ah oo qaabaysan- waa aalad ilaalin yar oo danab ah oo si toos ah u gooya wareegga marka ay ogaato culeyska xad dhaafka ah ama xaaladaha wareegga gaaban. Si ka duwan fiyuuska, dib ayaa loo dajin karaa oo dib ayaa loo isticmaali karaa safarka ka dib. Gudaha kiiska la qaabeeyey, habka safarka kuleyl-magnetic wuxuu qabtaa laba shaqo: curiyaha kulaylka ayaa ka jawaabaya culeyska joogtada ah, halka curiyaha birlabku uu isla markiiba uga falceliyo cilladaha wareegga gaaban. Natiijadu waa ilaalin u dhiganta sida culeysyada korantada dhabta ah u dhaqmaan.

Goorta la dooranayo MCCB: Quudiyoyaasha soo gala ee ugu muhiimsan, baalal qaybinta saddex-waji ah, wareegyada matoorada waaweyn, ama meel kasta oo mustaqbalka gaaban ee hadda socda uu ka badan yahay waxa MCB joojin karo.

Marka MCB ku filan yahay: wareeg-hoosaadyada ugu dambeeya oo leh culeys yar iyo heerar cilladeed oo hooseeya - looxyada deegaanka, iftiinka iyo wareegyada godka.

Sida loo doorto MCCB saxda ah

Hadda lagu qiimeeyay (In)

1. - waafaqid culayska joogtada ah, oo u ogolow qolka hore ee bilowga matoorada.

Awoodda jabinta (Icu / Ics)

2. - waa in uu ka sarreeyaa wakhtiga wareegga gaaban ee la filayo marka la rakibo. Markasta oo uu sareeyo heerka qaladka, ayaa sare u kacaysa Icu aad u baahan tahay.

Tiirarka

3. - 3P ee nidaamyada saddexda weji, 4P halkaas oo dhexdhexaadku uu sidoo kale u baahan yahay in la gooyo.

Qiimaynta korantada

4. - Hubi danab hawleedka lagu qiimeeyay (Ue), danab dahaarka (Ui) iyo adkaysiga dareenka (Uimp) lidka ku ah nidaamka.

Heerarka iyo shahaadaynta

5. - IEC/EN 60947-2 u hoggaansanaanta iyo calaamadaynta CE waa saldhigga mashaariicda caalamiga ah.

Codsiga

6. - Ilaalinta matoorka, qaybinta korantada iyo rakibaadda warshadaha waxay u baahan karaan qiimayno kala duwan iyo sifooyinka safarka.

Muxuu u eg yahay 250A MCCB oo si wanaagsan loo cayimay:

Si loo sameeyo tan la taaban karo, ka fiirso DAM3-250 ka C·DADA Electric — 250A saddex tiir MCCB ah oo sharraxaya waxa laga raadinayo fasalkan aaladda:

3P qaabeynta

● leh 250A lagu qiimeeyay hadda (In), oo ku habboon looxyada qaybinta saddexda weji

Qiimaynta korantada:

● 690V~; Ue AC400/415V, Ui 750V, Uimp 8kV

Awoodda jabinta ilaa 50kA

● — Icu oo ah 18/25/36/50 kA guud ahaan noocyada B/C/N/S, sidaa darteed rakibayaashu waxay la jaan qaadi karaan heerarka khaladka ah ee dhibcaha kala duwan ee shabakada

IEC/EN 60947-2 iyo GB 14048.2 u hoggaansanaanta

● CE waxay ku calaamadsan tahay, oo leh dami/dami toosan oo cad oo loogu talagalay xaalad hawleed oo muuqata

● Loo dhisay awood qaybinta, ilaalinta matoorka iyo codsiyada warshadaha

Caqliga ka dambeeya qeexitaankan: 250A, 3-bid jir ah oo leh 50kA heerka jabinta awoodda ayaa daboolaysa inta badan baahida dhismaha guddiga iyo qandaraaslaha - laga bilaabo guddiyada qaybinta ugu weyn ilaa wareegyada quudiyaha - halka noocyada kala duwan ee Icu ay kuu oggolaanayaan inaad cabbirto qiimaha saxda ah marka loo eego heerarka khaladka dhabta ah.

Talada xulashada

● Wareegyada ugu dambeeya ilaa ~125A oo leh heerar cilladeed hooseeya, MCB ayaa ah doorashada dhaqaale.

● Qaybinta ugu weyn, ilaalinta matoorka iyo qalabka warshadaha, dooro MCCB oo leh awood jabin oo ka sareysa rakibaadda hadda jirta ee gaaban.

● Marka shaki la galo, hal fasal kor u qaad marka la jebinayo awoodda: kala duwanaanshiyaha kharashku waa yar yahay, halka xadka ilaalintu uu noqon karo faraqa u dhexeeya khalad yar iyo maqnaansho weyn.

Su'aalaha soo noqnoqda

S: Waa maxay MCCB?

J: Akiis wareeg ah oo qaabaysanwaa qalab difaac yar oo danab yar oo dib loo dajin karo kaas oo kala gooya wareegga culeyska saaran ama wareegga gaaban, ee loogu talagalay qulqulka sare iyo heerarka cilladaha marka loo eego qalabka wareegga yar.

S: Maxay Icu uga jeedaa MCCB?

J: Icu waa awooda jabinta wareega-gaaban ee ugu dambeeya - khaladka ugu badan ee hadda jabiyahu wuu joojin karaa. Ics waa awoodda jebinta adeegga, heerka uu si joogto ah u joojin karo oo uu sii shaqeeyo.

S: Sideen ku dooran karaa awoodda jabinta MCCB-gayga?

J: Dooro qiimaynta Icu oo ka sarraysa wakhtiga wareegga gaaban ee la filayo marka la rakibo. Looxyada qaybinta ee leh awoodda wax beddelka sare ama quudiyeyaasha warshadaha dhaadheer waxay caadi ahaan u baahan yihiin 36-50kA aaladaha fasalka.

S: Waa maxay DAM3-250 MCCB?

A: DAM3-250 waa 250A saddex tiir oo ka samaysan wareegga wareegga wareegga wareegga ah ee C·DADA Electric, oo lagu qiimeeyay ilaa 690V oo leh awood jebin ilaa 50kA, qaybinta korantada, ilaalinta gawaarida iyo codsiyada warshadaha.
