Ama-circuit breaker ane-low-voltage-MCCB

1.Iyini iI-MCCB ?

Iziqephu zesekhethi ezibunjiwe zinganqamula i-curse ngokuzenzakalelayo ngemva kokuba i-current yeqe isilungiselelo sohambo.Ikesi lepulasitiki libhekisela ekusetshenzisweni kwezivikeli zepulasitiki njengekhese yangaphandle yedivayisi yokuhlukanisa amakhondakta nezingxenye zensimbi ezisekelwe phansi.Ama-circuit breaker abunjiwe ngokuvamile aqukethe iyunithi yohambo lwe-thermal-magnetic, kuyilapho amamodeli amakhulu afakwe izinzwa zohambo zesimo esiqinile.Iyunithi yohambo ihlukaniswe: uhambo lukazibuthe olushisayo nohambo lwe-elekthronikhi.Izilinganiso ezijwayelekile ezisetshenziswayo zimi kanje: 16, 25, 30, 40, 50, 63, 80, 100, 125, 160, 200, 225, 250, 315, 350, 400, 500, 630A.

2. Isici seI-MCCB ?

2.1:Ukuthobela izindinganiso ze-GB14048.2008;

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

2.3:Usayizi wozimele ukalwe okwamanje:63A;100A;225A;400A;630A;800A;

2.4:Umthamo omkhulu wokuphuka: kufika ku-100kA;

2.5:Idizayini enengqondo, ephephile futhi enokwethenjelwa, usayizi we-samll, isisindo esilula, ukubukeka okuhle;

2.6:Izesekeli yonke into, ukufakwa okusheshayo, kulula ukuyisebenzisa, ukusebenziseka okuqinile.

3.KanjaniI-MCCBisebenza?

Othintana nabo abakhulu be-low-voltage circuit breaker bavalwa ngesandla noma ngogesi.Ngemva kokuba othintana naye oyinhloko evaliwe, indlela yohambo lwamahhala ikhiya othintana naye oyinhloko endaweni evaliwe.Ikhoyili yokukhululwa kwe-overcurrent kanye ne-thermal element yokukhululwa kwe-thermal ixhunywe kuchungechunge nesekhethi eyinhloko, futhi ikhoyili yokukhishwa kwe-undervoltage ixhunywe ngokuhambisana nokunikezwa kwamandla.

Uma isekethe ine-circuited emfushane noma ilayishwe kakhulu, i-armature yokukhululwa kwe-overcurrent idonselwa ukuze kwenziwe indlela yokukhulula yamahhala isebenze, futhi othintana naye oyinhloko unqamula isekethe enkulu.

Uma isifunda sigcwele kakhulu, isici sokushisa sokukhululwa okushisayo sizogoba i-bimetal, iphushe indlela yokukhululwa yamahhala ukuze isebenze, futhi othintana naye oyinhloko uzonqamula isifunda esikhulu.

Uma isekethe ingaphansi kwe-voltage, i-armature ye-under-voltage release iyakhululwa, okwenza futhi indlela yokuhamba yamahhala isebenze, futhi othintana naye oyinhloko unqamula isekethe enkulu.

Lapho inkinobho ye-shunt tripping icindezelwa, i-armature ye-shunt tripper iyangena, okwenza indlela yohambo lwamahhala isebenze, futhi othintana naye oyinhloko unqamula isekethe enkulu.

4.Kungani u-Yueqing AIso?

4.1: Ubunjiniyela obugcwele nokusekelwa kobuchwepheshe: abakhiqizi abangochwepheshe abangu-3, ​​nethimba lesevisi yezobuchwepheshe.

4.2: Ikhwalithi ingu-No1, isiko lethu.

4.3: Izikhathi zokuhola ngokushesha:“Isikhathi siyigolide” kuwe nakithi

4.4: 30min impendulo esheshayo: sineqembu lochwepheshe, 7 * 20H

Thola ukwethenjwa kweklayenti ngenxa yedumela labo elifakazelwe lokuthembeka, ukusebenza nempilo ende.

Uma unombuzosnoma yiziphi izidingo zomkhiqizo, sicela ukhululeke ukuxhumana nami.
