Qhov sib xyaw ntawm cov fuse poob tsuas yog muaj cov khoom siv hluav taws xob, lub rooj txhawb nqa qis, qis zog sib cuag, qis qis qis qis, mounting phaj, sab sauv zoo li qub, duckbill, sab sauv sib cuag, fuse raj thiab lwm yam.
6. Qhov sib txawv ntawm cov kab hloov pauv
Lub ntsiab sib txawv yog raws li nram no:
Lub disconnecting hloov tsis muaj arc extinguishing ntaus ntawv, yog li nws tsuas yog tsim nyog rau kev txiav tawm tam sim no yam tsis muaj load, thiab nws tsis tuaj yeem txiav tawm lub load tam sim no thiab luv-circuit tam sim no, yog li lub disconnecting switch appliance tsuas yog ua haujlwm zoo nyob rau hauv cov xwm txheej. ntawm Circuit Court kev ruaj ntseg disconnection, thiab nws yog txwv tsis pub khiav lag luam nrog ib tug load, thiaj li tsis ua rau muaj kev huam yuaj.
Load hloov vim hais tias ntawm arc extinguishing ntaus ntawv, nrog ib tug tej yam arc extinguishing muaj peev xwm, tab sis tsis muaj zog raws li lub Circuit Court breaker arc extinguishing muaj peev xwm, nws muaj peev xwm phua qhov kev khiav hauj lwm tam sim no, luv luv Circuit Court, nws tsuas yog ntsiag to tiv thaiv luv luv tam sim no, Yog hais tias lub sij hawm no manually los yog hluav taws xob ua hauj lwm tripping tej zaum yuav tawg, yog li lub load hloov feem ntau yog siv nrog tam sim no-txheej fuse (load hloov + fuse tsis yog tus qauv configuration, tab sis kuj tsis tuaj yeem siv nrog lub fuse) Yog tias muaj ntau dhau. los yog luv luv Circuit Court yog tawg los ntawm ib tug fuse. Yuav kom txuag tau tus nqi, thauj khoom hloov pauv + fuse tuaj yeem siv tsis siv lub tshuab hluav taws xob.
Lub Circuit Court breaker muaj ib tug muaj zog arc extinguishing muaj peev xwm, thiab nws muaj peev xwm coj mus rhaub rau qhov qub ua hauj lwm tam sim no raws li qhov txhaum tam sim no. Kev tiv thaiv kev ua haujlwm ntawm Circuit Court breaker yog paub los ntawm cov khoom siv tiv thaiv relay. High-voltage Circuit Court breakers tsis muaj cov cuab yeej ntawm cov hluav taws xob qis hluav taws xob xws li thermal tso tawm, sib nqus tso tawm, kev tso tawm qis dua, thiab lwm yam. Txawm hais tias muaj kev ua txhaum ntawm txoj kab yog txiav txim los ntawm cov khoom siv tiv thaiv relay, thiab Circuit Court. breaker tsuas yog ua txhaum raws li cov lus qhia ntawm kev tiv thaiv relay. Load switches thiab disconnecting riam kuj tsis tas yuav muab cov lus txib rau lawv thaum txoj kab ua txhaum vim lawv tsis tuaj yeem ua txhaum tam sim no. Lub Circuit Court breaker yog ib qho kev hloov pauv uas muaj peev xwm tua hluav taws kub thiab yuav tsum tau siv ua ke nrog cov khoom siv tiv thaiv relay.
Los ntawm peb tuaj yeem xaus raws li hauv qab no:
Disconnecting hloov - tsuas yog qhib thiab txuas lub kaw lus tsis muaj kev thauj khoom tam sim no, thiab raws li cov kab hluav taws xob tseem ceeb pom kev cuam tshuam kev cuam tshuam, hauv cov txheej txheem kev saib xyuas raws li qhov system pom tseeb kev cuam tshuam. Cov qauv siv feem ntau: GW9, HGW9, GW4, GW5, thiab lwm yam.
Load hloov - tuaj yeem qhib thiab kaw qhov system ib txwm thauj khoom tam sim no, tab sis tsis tuaj yeem ua txhaum qhov system txhaum tam sim no. Cov qauv siv feem ntau: FZW32
Circuit Court breaker - Muaj peev xwm qhib thiab kaw qhov qub thauj khoom tam sim no ntawm lub cev, tab sis kuj tuaj yeem qhib thiab kaw qhov txhaum thiab luv-circuit tam sim no ntawm lub kaw lus. Cov qauv siv feem ntau: ZW32, ZW20, ZW7, ZW8, LW3, thiab lwm yam.
