Muab piv rau kev tiv thaiv kev ua tau zoo ntawm fuses thiab Circuit Court breakers, Circuit Court breakers tau piav qhia nyob rau hauv cov nqe lus ntawm hom tsis xaiv thiab xaiv hom, feem.
Ua ntej, lub fuse.
(1) Lub ntsiab zoo thiab cov yam ntxwv ntawm lub fuse.
① Kev xaiv zoo. Ntev npaum li qhov ntsuas tam sim no ntawm lub fuse txuas ntawm sab sauv thiab qis fuse ua tau raws li lub teb chaws tus qauv thiab kev xaiv overcurrent piv tau teev tseg los ntawm IEC tus qauv ntawm 1.6: 1, uas yog, qhov ntsuas tam sim no ntawm lub fuse sab saud tsis tsawg dua 1.6. lub sij hawm tus nqi ntawm cov qib qis, nws yog suav hais tias lub sab sauv thiab qis theem tuaj yeem xaiv txiav tawm qhov txhaum tam sim no;
② Zoo tam sim no txwv cov yam ntxwv thiab muaj peev xwm tawg siab;
③ Tus txheeb ze me me;
④ Tus nqi pheej yig.
(2) Lub ntsiab shortcomings thiab tsis muaj zog ntawm lub fuse.
① Lub fuse yuav tsum tau hloov tom qab fuse tsis ua haujlwm;
② Kev tiv thaiv ib leeg muaj nuj nqi, tsuas yog ib qho dhau-tam sim no hloov pauv lub sijhawm tus yam ntxwv, siv rau overload, luv Circuit Court thiab tiv thaiv hauv av;
③Thaum ib theem cua tshuab, peb-theem lub cev muaj zog yuav ua rau qhov tsis zoo ntawm kev ua haujlwm ob-theem. Tau kawg, lub fuse nrog lub tswb ceeb toom tuaj yeem siv los ua rau nws. Ib-theem cua tshuab tuaj yeem cuam tshuam peb-theem;
④ Kev tswj chaw taws teeb tsis tuaj yeem paub, nws yuav tsum tau ua ke nrog hluav taws xob riam hloov thiab hloov.
Thib ob, tsis yog xaiv Circuit Court breakers.
(1) Lub ntsiab zoo thiab cov yam ntxwv.
① Tom qab qhov kev ua txhaum raug txiav lawm, nws tuaj yeem rov pib dua manually yam tsis hloov cov khoom, tshwj tsis yog qhov loj luv luv tam sim no yuav tsum tau kho;
② Ob txoj haujlwm tiv thaiv kev tso tawm ntev thiab tam sim no tso tawm tam sim no nrog lub sijhawm hloov pauv yog siv rau kev tiv thaiv luv luv thiab luv luv raws li, thiab txhua tus ua nws txoj haujlwm;
③ Lub tshuab ua haujlwm nyob tau tuaj yeem paub cov chaw taws teeb tswj.
(2) Main shortcomings thiab tsis muaj zog.
①Nws yog ib qho nyuaj rau ua tiav cov kev xaiv txiav tawm ntawm sab sauv thiab sab qis uas tsis yog xaiv Circuit Court breakers. Thaum qhov txhaum tam sim no loj, lub sab sauv thiab sab hauv Circuit Court breakers tau yooj yim disconnected tam sim ntawd;
② Tus nqi txheeb ze dua me ntsis;
③ Qee qhov hluav taws xob hluav taws xob muaj peev xwm tawg me me. Piv txwv li, yog hais tias ib tug Circuit Court breaker nrog ib tug me me ntsuas tam sim no yog ntsia ze ntawm lub loj-muaj peev xwm transformer, lub peev xwm tawg yog tsis txaus. Tam sim no cov khoom uas muaj peev xwm tawg tau txaus siab, tab sis tus nqi siab dua.
Thib peb, xaiv lub Circuit Court breaker.
(1) Lub ntsiab zoo thiab cov yam ntxwv.
①Nws muaj qhov zoo ntawm cov lus hais saum toj no uas tsis yog xaiv Circuit Court breakers;
②Nws muaj ntau yam kev tiv thaiv kev ua haujlwm, suav nrog kev ncua sij hawm ntev, sai sai, ncua sij hawm luv luv thiab hauv av txhaum (xws li xoom ntu tam sim no thiab qhov seem tiv thaiv tam sim no) kev tiv thaiv, uas tuaj yeem paub txog overload, qhib Circuit Court ncua, luv luv Circuit Court tam sim no tam sim no thiab hauv av Kev tiv thaiv kev txhaum feem, Kev tiv thaiv siab, yooj yim los kho ntau yam tsis muaj, yooj yim kom tau raws li ntau yam kev tiv thaiv cov cai ntawm cov kab hluav taws xob. Tsis tas li ntawd, nws tseem tuaj yeem muaj kev tiv thaiv cascade, uas muaj kev xaiv zoo dua kev ua haujlwm.
③ Feem ntau ntawm cov khoom tam sim no muaj cov yam ntxwv ntawm kev txawj ntse. Ntxiv nrog rau kev tiv thaiv kev ua haujlwm, lawv kuj muaj kev ntsuas hluav taws xob, kev kaw lus tsis raug, kev sib txuas lus kev zam txim, thiab lwm yam, kom ua tiav kev saib xyuas hauv nruab nrab thiab kev tswj hwm ntawm cov khoom siv hluav taws xob thiab cov tshuab.
(2) Qhov teeb meem loj.
(1) Tus nqi yog siab heev, thiab nws tsuas yog siv tau rau ntawm thawj qhov kawg ntawm cov kab xa tawm thiab cov chaw tseem ceeb tshwj xeeb;
②Qhov loj dua.
