I-Molded Case Circuit Breaker (MCCB) Isikhokelo esiSiseko

Ukubunjwa Case Circuit Breakers(MCCB) yinxalenye ebalulekileyo yayo nayiphi na inkqubo yombane, ebonelela ngokugqithiswa okuyimfuneko kunye nokukhusela isiphaluka esifutshane. Ezi zixhobo zidla ngokufakelwa kwiphaneli yombane engundoqo ukuze kuvuleleke ukuvalwa kwesixokelelwano xa kuyimfuneko. Ii-MCCBs ziza ngobukhulu obahlukeneyo kunye nokulinganisa kwaye zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kweenkqubo zombane.

Amacandelo kunye neempawu

Isiqhelo esibunjiweyo sesaphuli sesekethe sineenxalenye ezininzi ezibalulekileyo, kubandakanywa iyunithi yohambo, indlela yokusebenza kunye nabafowunelwa. Iyunithi yohambo inoxanduva lokubona ukugqithiswa kunye neesekethe ezimfutshane, ngelixa indlela yokusebenza ivumela ukusebenza ngesandla kunye nokulawula kude. Abafowunelwa benzelwe ukuvula nokuvala iisekethe njengoko kufuneka, ukubonelela ngokhuseleko oluyimfuneko.

Umgaqo osebenzayo weplastiki yecala le-circuit breaker
I-MCCB isebenza ngokubeka iliso kumbane oqukuqelayo. Xa i-overload okanye isiphaluka esifutshane sifunyenwe, iyunithi yohambo ibangela ukuba abafowunelwa bavuleke, baphazamise ngokufanelekileyo ukuhamba kombane kunye nokuthintela umonakalo onokuthi ubekho kwinkqubo. Le mpendulo ngokukhawuleza ibalulekile ekukhuseleni iziseko zombane kunye nezixhobo ezixhunyiwe.

Iintlobo kunye neenzuzo
Ii-MCCB zifumaneka kwiindidi ezahlukeneyo, nganye ilungiselelwe ukuhlangabezana neemfuno ezithile. I-voltage elinganisiweyo ye-insulation ye-molded case circuit breaker yi-1000V, efanelekile ukutshintshwa okungaqhelekanga kunye nemoto eqala kwiisekethe ze-AC 50Hz. Zilinganiswe kwii-voltages zokusebenza ukuya kwi-690V kunye nemilinganiselo yangoku ukuya kwi-800 ACSDM1-800 (ngaphandle kokukhuselwa kwemoto). Ukuthobela imigangatho efana ne-IEC60947-1, i-IEC60947-2, i-IEC60947-4 kunye ne-IEC60947-5-1, i-MCCB iyisisombululo esisebenzayo nesithembekileyo kwizicelo ezahlukeneyo.

Iinzuzo zokusebenzisa i-MCCBs kwiinkqubo zombane zininzi. Banikezela ngokhuseleko oluyimfuneko kwiimpazamo zombane, ukuqinisekisa ukhuseleko lwabasebenzi kunye nezixhobo. Ukongeza, ii-MCCBs kulula ukuzifaka kunye nokugcina, zinceda ukuphucula ukusebenza kakuhle kweziseko zombane.

Ngamafutshane, ii-breakers zesekethe ezibunjiweyo ziyimfuneko ekusebenzeni okukhuselekileyo nokuthembekileyo kweenkqubo zombane. Ukuqonda amacandelo ayo, imisebenzi, kunye nemigaqo yokusebenza kubalulekile ekwenzeni izigqibo ezinolwazi malunga nokukhetha kwayo kunye nokuphunyezwa kwayo. Ngokuguquguquka kwazo kunye namandla okukhusela, ii-MCCBs zisisiseko sobunjineli bombane banamhlanje kwaye zidlala indima ephambili ekukhuseleni iziseko ezingundoqo.
