Lub thav duab Circuit Court breaker muaj feem xyuam rau lub network faib nrog AC 50Hz, ntsuas voltage ntawm 380V thiab 660V, thiab ntsuas tam sim no ntawm 200a-6300a.Nws yog tsuas yog siv los faib hluav taws xob hluav taws xob thiab tiv thaiv kab thiab cov khoom siv hluav taws xob los ntawm overload, undervoltage, luv Circuit Court, ib-theem grounding thiab lwm yam txhaum.Lub Circuit Court breaker muaj ntau yam kev tiv thaiv kev txawj ntse thiab tuaj yeem ua tiav kev tiv thaiv xaiv.Raws li ib txwm muaj, nws tuaj yeem siv rau kev hloov kab tsis tu ncua.Lub Circuit Court breaker hauv qab 1250A tuaj yeem siv los tiv thaiv lub overload thiab luv luv Circuit Court ntawm lub cev muaj zog hauv lub network nrog AC 50Hz voltage ntawm 380V.
Tus ncej hom Circuit Court breaker kuj feem ntau siv rau cov kab txuas txuas tseem ceeb, tsheb npav khi hloov, lub peev xwm loj hloov pauv thiab lub cev muaj zog loj hloov pauv ntawm 400V sab ntawm lub transformer.

Peb Yuye hom thav duab Circuit Court breaker tau npog tag nrho cov ntsuas tam sim no, mus txog 6300A, thiab tau dhau CQC ntawv pov thawj

.

Basic yam ntxwv parameter ntawm Circuit Court breaker

(1) Rated ua haujlwm voltage Ue

Qhov ntsuas kev khiav hauj lwm voltage yog hais txog qhov nominal voltage ntawm lub Circuit Court breaker, uas tuaj yeem ua haujlwm tsis tu ncua raws li kev siv ib txwm siv thiab kev ua haujlwm.
Tuam Tshoj qhia tias qhov siab tshaj plaws ua haujlwm voltage yog 1.15 npaug ntawm qhov ntsuas hluav taws xob ntawm qhov system ntawm qhov voltage ntawm 220kV thiab hauv qab no;Qib voltage ntawm 330kV thiab siab dua yog 1.1 npaug ntawm qhov ntsuas hluav taws xob raws li qhov ua haujlwm siab tshaj plaws.Lub Circuit Court breaker tuaj yeem tswj cov rwb thaiv tsev nyob rau hauv qhov kev ua haujlwm siab tshaj plaws ntawm qhov system, thiab tuaj yeem ua thiab tawg raws li cov xwm txheej tau teev tseg.

(2) Rated tam sim no (hauv)

Rated tam sim no yog hais txog qhov tam sim no uas qhov kev tso tawm tuaj yeem dhau mus ntev thaum qhov kub ntawm qhov ntsuas kub qis dua 40 ℃.Rau lub Circuit Court breaker nrog adjustable tso tawm, nws yog qhov siab tshaj plaws tam sim no uas qhov kev tso tawm tuaj yeem dhau mus ntev.
Thaum lub ambient kub tshaj 40 ℃ tab sis tsis siab tshaj 60 ℃, nws raug tso cai kom txo cov load thiab ua hauj lwm ntev.

(3) Tshaj tawm tshaj tawm tam sim no teeb tsa tus nqi IR

Yog tias qhov tam sim no tshaj qhov teeb tsa tam sim no tus nqi IR ntawm kev tso tawm, lub Circuit Court breaker yuav ncua tripping.Nws kuj sawv cev rau qhov siab tshaj plaws tam sim no uas lub Circuit Court breaker tuaj yeem tiv taus yam tsis muaj tripping.Tus nqi no yuav tsum ntau dua qhov siab tshaj plaws load tam sim no IB tab sis tsawg dua qhov siab tshaj plaws tam sim no iz tso cai los ntawm kab.
Lub thermal disconnect relay IR tuaj yeem hloov kho nyob rau hauv qhov ntau ntawm 0.7-1.0in, tab sis yog siv cov khoom siv hluav taws xob, qhov kev hloov kho ntau dua, feem ntau yog 0.4-1.0in.Rau lub Circuit Court breaker nruab nrog tsis adjustable overcurrent mus txawv tebchaws relay, IR = nyob rau hauv.

(4) luv Circuit Court tso tawm tam sim no tus nqi im

Lub luv luv-circuit tripping relay (instantaneous los yog luv luv) yog siv los sai sai mus rau lub Circuit Court breaker thaum muaj teeb meem tam sim no, thiab nws qhov pib tripping yog im.

(5) Lub sijhawm luv luv tiv thaiv ICW tam sim no

Hais txog tus nqi tam sim no tso cai hla dhau lub sijhawm pom zoo.Tus nqi tam sim no yuav dhau los ntawm tus neeg xyuas pib hauv lub sijhawm pom zoo, thiab tus neeg xyuas pib yuav tsis raug puas tsuaj vim overheating.

(6) Lub peev xwm tawg

Lub peev xwm tawg ntawm Circuit Court breaker yog hais txog lub peev xwm ntawm Circuit Court breaker kom muaj kev nyab xeeb txiav tawm qhov txhaum tam sim no, uas tsis tas yuav cuam tshuam nrog nws cov ntsuas tam sim no.Muaj 36ka, 50kA thiab lwm yam specifications.Nws feem ntau muab faib ua txwv luv luv-circuit breaking peev ICU thiab ua haujlwm luv-circuit breaking peev ICs.
