Abaphuli beeSekethe zeTyala eziMoluliweyo: Ukhuseleko oluSebenza ngeendlela ezahlukeneyo kwiinkqubo zoMbane

yazisa:

Kwinjineli yombane,abaphuli beesekethe zetyala elibunjiweyo (IiMCCB) zizinto ezibalulekileyo ekukhuseleni iinkqubo zombane kwimithwalo enzima, ii-short circuits kunye nezinye iindlela zokungasebenzi kakuhle.IiMCCBZisetyenziswa kakhulu kwiindawo ezahlukeneyo zokuhlala, zorhwebo kunye nemizi-mveliso ukuqinisekisa ukusebenza kakuhle nangokukhuselekileyo kweenkqubo zombane. Kweli nqaku, siza kuhlola ukusetyenziswa, iimpawu kunye nezinto eziqwalaselwa yi-MCCBs.

Ukusetyenziswa kweiqhekeza lesekethe elibunjiweyo:

IiMCCBzisetyenziswa kwiintlobo ngeentlobo zezicelo, kuquka:

1. Izicelo zemizi-mveliso: Ii-MCCB zisetyenziswa rhoqo kwizicelo zemizi-mveliso ukubonelela ngokhuseleko kwiinkqubo zombane kwimithwalo engaphezulu, ii-short circuits, kunye nezinye iintlobo zeziphene. Ezi zicelo ziquka imveliso, ioyile negesi, ukumbiwa kwemigodi kunye nezinye iindawo zoshishino.

2. Izicelo zorhwebo: Ii-molded case circuit breakers zisetyenziswa kwizicelo zorhwebo, ezifana neevenkile ezinkulu, iihotele, izakhiwo zeeofisi, njl.njl., ukuqinisekisa ukusebenza kakuhle nangokukhuselekileyo kweenkqubo zombane.

3. Izicelo zokuhlala: Ii-molded case circuit breakers zisetyenziswa kwiindawo zokuhlala ukuqinisekisa ukhuseleko lwabantu abahlala endlwini. Zifakwe kwiibhokisi zokusasaza ukuze kukhuselwe ii-circuits kwiingxaki zombane.

Iimpawu zee-molded case circuit breakers:

1. Umlinganiselo wamandla: Umlinganiselo wamandla ombane wee-molded case circuit breakers wahlukile, ukusuka kwii-ampere ezimbalwa ukuya kwii-ampere ezininzi. Olu phawu luyenza ikwazi ukusetyenziswa kwiindlela ezahlukeneyo zokusebenza.

2. Uphawu lokukhubeka: I-molded case circuit breaker ineempawu zokukhubeka, eziqinisekisa ukuba i-circuit iyakhubeka xa kukho ingxaki yombane ukuthintela umonakalo ongakumbi. Uphawu lokukhubeka lunokuba lobushushu okanye olunemagnethi.

3. Umthamo ophezulu wokuqhekeza: I-molded case circuit breaker inomthamo ophezulu wokuqhekeza kwaye inokumelana nomsinga omkhulu wempazamo ngaphandle kokuqhekeka. Olu phawu luqinisekisa ukuba i-circuit ikhuselekile ekonakaleni.

4. Ukukhetha: I-molded case circuit breaker inika ukhetho kwinkqubo yombane, oko kukuthi, kuphela i-molded case circuit breaker ekufutshane nee-fault trips, ngelixa ezinye ii-circuits kwinkqubo yombane zingachaphazeleki.

Amanyathelo okukhetha ii-molded case circuit breakers:

1. Umlinganiselo wamandla: Xa ukhetha i-molded case circuit breaker, kufuneka kuqinisekiswe ukuba umlinganiselo wamandla wenkqubo yombane omiselweyo unokumelana nomlinganiselo wamandla ngaphandle kokukhubeka.

2. Uhlobo lokusilela: Uhlobo lokusilela oluyilwe yi-MCCB luyinto ebalulekileyo ekufuneka iqwalaselwe xa kukhethwa i-MCCB. Umzekelo, ezinye ii-MCCB zenzelwe ukukhusela ukusilela kobushushu, ngelixa ezinye zenzelwe ukukhusela ukusilela kwemagnethi.

3. Ubushushu obuphakathi: Ubushushu obuphakathi kwindawo engqongileyo apho kukho i-molded case circuit breaker nayo ibalulekile. I-MCCB inomlinganiselo wobushushu kwaye isenokungasebenzi kakuhle ukuba ubushushu obuphakathi budlula umlinganiselo we-MCCB.

Ngamafutshane: I-MCCB yinxalenye ebalulekileyo kwinkqubo yombane njengoko ikhusela kwiimpazamo zombane. Inee-currents ezahlukeneyo ezilinganisiweyo, iimpawu zokukhubeka kunye nomthamo wokuphuka, ngoko ke ifanelekile kwiindlela ezahlukeneyo zokusetyenziswa. Xa ukhetha i-MCCB, umlinganiselo wangoku, uhlobo lwempazamo, kunye nobushushu be-ambient kufuneka kuqwalaselwe ukuqinisekisa ukusebenza ngokufanelekileyo.
