Kev cuam tshuam ntawm Ambient Temperature ntawm Circuit Breaker yam ntxwv

Circuit Breaker yog ib qho ntawm cov khoom siv hluav taws xob siv dav hauv kev faib khoom. Cov neeg siv khoom feem ntau txhawj xeeb txog yuav ua li cas txo lub peev xwm ntawm ntau hom hluav taws xob hluav taws xob hauv ntau qhov chaw thiab cov xwm txheej. Piv txwv li, lub Circuit Court breaker yog ntsia rau hauv tag nrho cov khoom siv hluav taws xob (switchgear, lub thawv), vim muaj ntau yam khoom siv hluav taws xob (riam hloov (los yog hloov load), contactor, circuit breaker, txuas tooj liab bar, thiab lwm yam). Ib qho teeb meem uas yuav tsum tau xav txog yog qhov cuam tshuam ntawm qhov kub thiab txias ntawm cov yam ntxwv ntawm Circuit Court breaker.
1 Cov ntaub ntawv yas hom Circuit Court breaker
Los ntawm cov tam sim no ntau ntawm cov yas plhaub Circuit Court breakers muag nyob rau hauv domestic thiab txawv teb chaws kev lag luam, muaj tag nrho cov electromagnetic hom (feem ntau hu ua roj khob hom tso), thermal-electromagnetic tso hom, hluav taws xob tso tawm thiab microprocessor tso tawm thiab hais txog.
1) Lub tshuab electromagnetic roj khob mus txawv tebchaws tsis yog tsuas yog siv rau kev thauj mus los ntev, tab sis kuj tseem siv rau kev tiv thaiv luv luv tam sim no (uas yog, kev tiv thaiv overload thiab luv Circuit Court siv tib lub khob roj mus txawv tebchaws). Qhov kev ncua ntev ntawm kev tiv thaiv kev ncua ntev yog nyob ntawm cov tshuaj tiv thaiv lub caij nplooj ntoos hlav hauv lub khob roj thiab cov roj methyl silicone kom damp lub nce siab ntawm cov tub ntxhais floating (thaum cov tub ntxhais ntab hauv lub khob roj yog nyob rau hauv ib qho loj tam sim no, nws muaj peev xwm kos tau rau hauv lub zog ntawm cov tub ntxhais. mus ncig teb chaws ntaus ntawv armature tsis floating upward kom lub Circuit Court breaker mus txawv tebchaws).
2) Tus naj npawb loj tshaj plaws yog siv cov thermodynamic - electromagnetic hom. Nws overload ncua ncua sij hawm siv kub bimetal Cheebtsam, luv luv Circuit Court tam sim no siv electromagnet system. Cov tuam txhab sib txawv, nyob rau hauv cov lus qhia lossis cov qauv, coj kev sib raug zoo ntawm kev khiav hauj lwm tam sim no thiab qhov kub thiab txias ntawm lub Circuit Court breaker muaj peev xwm txo lub rooj, los yog nyob rau hauv qhov nkhaus ntawm qhov kub thiab txias tam sim no, hu ua kub them nyiaj nkhaus.
3) Overcurrent tiv thaiv Circuit Court breaker rau tsev neeg lossis cov chaw zoo sib xws. Lub Circuit Court breaker ua raws li tus qauv GB10963, nws txawv ntawm 1), 2) chav kawm (nyob rau hauv txoj kab nrog GB14048.2) yog qhov ntsuas ntsuas ntsuas kub yog 30 degrees, (ntawm chav kawm, raws li kev tiv thaiv cov khoom siv hauv tsev, nws overload. ncua ntev thiab luv luv Circuit Court tiv thaiv cov yam ntxwv tsis zoo ib yam).
2 Universal (thav duab) Circuit Court breaker
1) Universal Circuit Court breaker, xws li DW15-630 muaj thermal-electromagnetic hom (siv thermal relay rau overload ncua ncua kev tiv thaiv, electromagnetic mus ncig teb chaws rau luv luv Circuit Court tiv thaiv), nws muaj peev xwm txo yog yeej ib yam li cov yas- case thermal-electromagnetic hom. Lwm yam universal circuit breakers, xws li SRW45 universal circuit breakers yog tib yam.
2) Electronic tso tawm (nrog rau microprocessor tso tawm)
Hluav taws xob thiab microprocessor mus txawv tebchaws breakers yog siv ntau dua nyob rau hauv universal (thav duab hom) Circuit Court breakers. Tam sim no, yas plhaub Circuit Court breakers nrog loj tam sim no specifications yog siv nyob rau hauv industrial electronics Cheebtsam, uas hloov mus rau ib tug dav ambient kub ntau yam (-40-85), uas yog, nyob rau hauv no kub ntau yam, kev ua tau zoo ntawm cov khoom siv hluav taws xob yuav tsis hloov. . Kev tshuaj xyuas yog vim li cas: qhov kev hloov pauv ntawm qhov kub thiab txias tsis cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob. High tam sim no specifications poob peev xwm vim hais tias cov hlau tooj liab ntawm high tam sim no cua sov tshwm sim los ntawm qhov nce ntawm tag nrho cov kub nce. Rau cov khoom siv hluav taws xob tsawg, qhov ntsuas kub nyob hauv 10-40 Circuit Court breaker kub nce qhov pib tsis muaj txiaj ntsig, thiab ntau dua 40 muaj kev cuam tshuam, qhov cuam tshuam me me.
Txhawm rau ua kom tiav, thaum qhov ntsuas kub ntawm qhov ntsuas kub siab tshaj qhov ntsuas kub rau qhov ntsuas hluav taws xob ntsuas hluav taws xob, lub ntsuas hluav taws xob ntsuas hluav taws xob tau teeb tsa hauv lub txee hloov pauv yuav tsum tsim nyog txo tus nqi tam sim no, uas yog qhov ntsuas tam sim no sib npaug los ntawm qhov muaj peev xwm txo qis. Qhov siab tshaj plaws ambient kub (lub thawv thiab txee ib puag ncig) ntawm tag nrho cov khoom siv sib txawv raws li hom thiab qhov ntau ntawm cov khoom siv hluav taws xob sab hauv. Cov neeg siv yuav tsum siv qhov siab tshaj plaws qhov ntsuas qhov ntsuas kub, xws li 50, 55 lossis 60, thiab tom qab ntawd txo lub peev xwm raws li qhov ntsuas kub tam sim no lossis qhov ntsuas kub tau muab los ntawm cov chaw tsim khoom hluav taws xob hluav taws xob.
