Izaphuli zesekethe ezisezantsi-MCCB

1.Yintoni iI-MCCB ?

Izaphuli zesekethe ezibunjiweyo zinokuwucima ngokuzenzekelayo umsinga emva kokuba umsinga ugqithise ulungiselelo lohambo.Icala leplastiki libhekisela ekusetyenzisweni kwee-insulators zeplastiki njenge-casing yangaphandle yesixhobo sokuhlukanisa abaqhubi kunye neengxenye zetsimbi ezisekelwe phantsi.Izaphuli zesekethe ezibunjiweyo zihlala zineyunithi yohambo lwe-thermal-magnetic, ngelixa iimodeli ezinkulu zixhotyiswe nge-slid-state sensors zohambo.Iyunithi yohambo yahlulwe yaba: uhambo lwemagnethi eshushu kunye nohambo lombane.Ireyithingi ezisetyenziswa ngokuqhelekileyo imisinga zezi zilandelayo: 16, 25, 30, 40, 50, 63, 80, 100, 125, 160, 200, 225, 250, 315, 350, 400, 500, 630A.

2. Uphawu lweI-MCCB ?

2.1:Ukuthobela imigangatho ye-GB14048.2008;

2.2:I-voltage ye-insulation elinganisiweyo: 800V;

2.3:Ubungakanani besakhelo silinganiswe ngoku: 63A;100A;225A;400A;630A;800A;

2.4:Umthamo ophezulu wokuqhawula: ukuya kuthi ga kwi-100kA;

2.5:Uyilo olunengqiqo, olukhuselekileyo noluthembekileyo, ubungakanani besamll, ubunzima obulula, inkangeleko entle;

2.6:Izincedisi yonke into, ukufakwa ngokukhawuleza, kulula ukuyisebenzisa, ukusetyenziswa okunamandla.

3.NjaniI-MCCBisebenza?

Abafowunelwa abaphambili be-low-voltage circuit breaker bavalwe ngesandla okanye ngombane.Emva kokuba uqhagamshelwano oluphambili luvaliwe, indlela yohambo lwasimahla ivalela umfowunelwa oyintloko kwindawo evaliweyo.I-coil yokukhutshwa kwe-overcurrent kunye ne-thermal element yokukhululwa kwe-thermal idibaniswe kwichungechunge kunye nesekethe eyintloko, kwaye i-coil yokukhutshwa kwe-undervoltage ixhunywe ngokuhambelana nokunikezelwa kwamandla.

Xa isiphaluka sifutshane okanye sigxininiswe kakhulu, i-armature yokukhululwa kwe-overcurrent itsalwa ukuze yenze inkqubo yokukhululwa kwamahhala, kwaye uqhagamshelwano oluphambili luqhawula isiphaluka esiphambili.

Xa isiphaluka sigqithisekile, into yokufudumala yokukhutshwa kwe-thermal iya kugoba i-bimetal, iqhube i-free release mechanism, kwaye umnxibelelwano oyintloko uya kuqhawula isiphaluka esiphambili.

Xa isiphaluka siphantsi kwe-voltage, i-armature ye-under-voltage release ikhululwe, eyenza ukuba i-free trip mechanism isebenze, kwaye uqhagamshelwano oluphambili luqhawula isiphaluka esiphambili.

Xa iqhosha lokutyibiliza licinezelwa, i-armature ye-shunt tripper iyatsala, yenza indlela yohambo lwasimahla lusebenze, kwaye umfowunelwa oyintloko uqhawula uqhagamshelwano lwesekethe engundoqo.

4.Kutheni uYueqing AIso?

4.1: Ubunjineli obugcweleyo kunye nenkxaso yobugcisa: Abavelisi be-3 abaqeqeshiweyo, kunye neqela lenkonzo yobugcisa.

4.2: Umgangatho nguNo1, inkcubeko yethu.

4.3: Amaxesha okukhokela ngokukhawuleza: “Ixesha ligolide” kuwe nakuthi

4.4: 30min impendulo ngokukhawuleza: sineqela lobuchwephesha, 7 * 20H

Fumana ukuthembela kwabathengi ngenxa yodumo lwabo oluqinisekisiweyo lokuthembeka, ukusebenza kunye nobomi obude.

Ukuba unombuzosokanye nayiphi na imveliso efunekayo, nceda uzive ukhululekile ukuba uqhagamshelane nam.
