I-switchgear ye-voltage ephansi kanye ne-controlgear

Imiqondo eyisisekelo:
I-switchgear kanye nemishini yokulawula yitemu eliyisisekelo, elihlanganisa i-switchgear kanye nenhlanganisela yayo nokulawula okusizayo, ukutholwa, ukuvikela nokulungisa izinto.Kuhlanganisa futhi inhlanganisela yezinto zikagesi namadivayisi anezintambo zangaphakathi, izisetshenziswa ezisizayo, izindlu kanye nezingxenye ezisekelayo zesakhiwo.I-Switchgear isetshenziselwa ukukhiqiza amandla, ukudlulisa, ukusabalalisa kanye nemisebenzi yokuguqula amandla kagesi.Impahla yokulawula isetshenziselwa umsebenzi wokulawula wedivayisi yokusetshenziswa kwamandla.

I-switchgear nemishini yokulawula ihlanganisa imiqondo emithathu eyisisekelo:

• ukuzihlukanisa
Ukuze uvikeleke, nqamula ugesi noma uhlukanise idivayisi noma ingxenye yebhasi kumphakeli ngamunye wamandla ukuze wakhe ingxenye engayodwa yocingo (isibonelo, uma kudingekile ukusebenza kusikhondatha esibukhoma).Okufana nokushintshwa komthwalo, isinqamuli, isinqamuli sesifunda esinomsebenzi wokuzihlukanisa, njll.

• lawula (ucishiwe)
Ngenhloso yokusebenza nokugcinwa, xhuma noma unqamule ngaphansi kwezimo ezijwayelekile zokusebenza.Okufana ne-contactor kanye ne-motor starter, switch, switch yesimo esiphuthumayo, njll.

• isivikelo
Ukuze uvimbele izimo ezingavamile zezintambo, izinto zokusebenza kanye nabasebenzi, njengokulayisha ngokweqile, isifunda esifushane kanye nephutha lesisekelo, indlela yokunqamula i-fault current isetshenziselwa ukuhlukanisa iphutha.Okufana nalokhu: i-circuit breaker, shintsha iqembu le-fuse, inhlanganisela edluliswayo evikelayo kanye nokulawula izinto zikagesi, njll.

I-switchgear

1. I-Fuse:
Isetshenziswa kakhulu njengesivikelo se-short-circuit.Lapho isekethe ifinyezwa noma ilayishwe kakhulu, izoxhuma ngokuzenzakalelayo futhi inqume isekethe ukuze ivikeleke.Ihlukaniswe ngohlobo olujwayelekile kanye nohlobo olukhethekile lwe-semiconductor.

2. Iswishi yokulayisha / i-fuse switch (shintsha iqembu le-fuse):
Imishini yokushintsha imishini ekwazi ukuxhuma, iphathe futhi inqamule isimanjemanje esivamile futhi iphathe okwamanje ngaphansi kwezimo ezingavamile (lawa maswishi awakwazi ukunqamula i-short-circuit yamanje)

3. I-Frame circuit breaker (ACB):
Isilinganiso samanje singu-6300A;I-voltage elinganiselwe ku-1000V;Ukuphula amandla kuze kufike ku-150ka;Ukukhishwa kokuvikela ngobuchwepheshe be-microprocessor.

4. I-Molded case circuit breaker (MCCB):
Isilinganiso samanje singu-3200A;I-voltage elinganiselwe ku-690V;Ukuphula amandla kuze kufike ku-200kA;Ukukhishwa kokuvikela kusebenzisa ubuchwepheshe be-electromagnetic noma i-microprocessor eshisayo.

5. I-Miniature circuit breaker (MCB)
Inani lamanje elilinganiselwe alikho ngaphezu kwe-125A;I-voltage elinganiselwe ku-690V;Amandla okuphula aze afike ku-50kA

6. Ukukhishwa kokuvikelwa kwe-electromagnetic okushisayo kuyamukelwa
I-Residual current (evuzayo) i-circuit breaker (rccb/rcbo) I-RCBO ngokuvamile yakhiwa i-MCB kanye nezinsiza zamanje ezisele.Isekhethi encane kuphela enokuvikelwa kwamanje okusalayo ibizwa ngokuthi i-RCCB, kanti idivayisi yokuvikela esele ibizwa ngokuthi i-RCD.
