Cov neeg txav tau kev sib cuag ntawm ob qho kawg ntawm lub raj fuse tau nrawm dua los ntawm kev txuas (yaj). Tom qab thawb lub txav sab saud mus rau sab nrauv tiv thaiv ntawm" duckbill", sab saud sab saud ua los ntawm phosphor tooj liab ntawv thiab lwm yam yog nias tiv thaiv kev sib cuag sab saud lub taub hau, yog li lub raj fuse yog khov kho hauv" duckbill" ;. Thaum lub luv luv-qhov hluav taws xob tam sim no yog tshuab los ntawm kev fuse, ib qho arc yog tsim. Lub thawv ntawv steel hlau nrog txoj kab txuas fuse ua rau muaj cov roj ntau ntau hauv qab qhov txiav txim ntawm arc. Sab qaum kawg ntawm lub raj fuse raug kaw, thiab cov pa roj yog muab tso tseg rau hauv qis kawg kom tawg tawm lub arc. Vim tias lub tshuab fuse, qhov sib txuas sab saud thiab qis dua ntawm kev sib txuas ntawm lub raj fuse poob qhov kev nruj ntawm lub fuse. Raws li qhov kev ua ntawm lub fuse tube' s tus kheej kev sib tsoo thiab sab saud thiab qis qis sib txuas ntawm lub qhov dej tawm, lub fuse tub sai sai poob, tawg Circuit Court. , Txiav tawm ntawm cov kab txhaum lossis cov khoom siv tsis raug.
Hauv qhov tseeb 10 kV kab system thiab lub fuse ntawm lub tshuab hluav taws xob tsis tuaj yeem ua haujlwm tau raug, ib qho laj thawj yog qhov zoo ntawm lub tshuab hluav taws xob tsis zoo, lub siab ntawm lub luag haujlwm tsis muaj zog, thiab kev saib xyuas thiab kho qhov tso tawm fuse tsis tau nqa tag nrho cov xyoo puag ncig; qhov laj thawj thib ob yog Cov khoom zoo ntawm kev tso tawm fuse yog qhov qis qis dua thiab tsis tuaj yeem rub tawm lossis kaw tsis tau. Ob qho laj thawj txo txoj haujlwm ntawm kev xa tawm-fuse. Hauv kev muaj tiag, nws feem ntau tshwm sim uas tsis muaj lub raj raj ua kom tsis muaj hmoov, tsis muaj yaj, lossis siv tooj liab tooj liab, txhuas xaim lossis txawm tias xaim hlau los hloov cov yaj. Ua kom tus nqi mus txawv tebchaws hauv kab thiab tsis ua hauj lwm tus nqi ntawm cov tshuab xa hluav taws xob nyob siab.
