Lub fuse cutout, qee zaum hu ua cutout fuse lossis dropout fuse, yog ib qho tseem ceeb hauv lub zog faib hluav taws xob. Nws ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv lub cev nrog rau kev nyab xeeb ntawm tib neeg thiab khoom siv.
Lub luag haujlwm tseem ceeb ntawm lub fuse cutout yog los tiv thaiv lub zog faib hluav taws xob los ntawm overcurrents. Overcurrent yog ib qho teeb meem hluav taws xob thaum tam sim no ntws hauv Circuit Court tshaj li qhov ua haujlwm ib txwm muaj. Overcurrents tuaj yeem tshwm sim vim muaj ntau yam xws li luv luv Circuit Court, khoom siv tsis ua haujlwm, thiab hluav taws xob surges.
Thaum ib qho kev tshwm sim overcurrent tshwm sim, lub fuse cutout ua haujlwm kom tshem tawm qhov yuam kev ntawm Circuit Court los ntawm qhov seem ntawm qhov system. Lub fuse cutout muaj ib lub fuse uas melts thaum lub tam sim no tshaj li ib tug predetermined theem, txiav tawm cov ndlwg ntawm hluav taws xob. Yog li ntawd, lub fuse cutout tiv thaiv cov khoom siv downstream los ntawm kev puas tsuaj thiab tiv thaiv kev nce ntxiv ntawm qhov txhaum.
Fuse cutouts yog tsim los kom muaj kev cuam tshuam tshwj xeeb. Qhov kev ntsuas cuam tshuam yog qhov siab tshaj plaws ntawm tam sim no uas lub fuse cutout tuaj yeem cuam tshuam kev nyab xeeb. Nws yog ib qho tseem ceeb heev uas yuav tau xaiv lub fuse cutout nrog ib qho kev cuam tshuam zoo rau daim ntawv thov kom muaj kev tiv thaiv zoo ntawm lub cev.
Lwm lub luag haujlwm ntawm lub fuse cutout yog muab lub peev xwm thauj khoom tawg ntawm qhov chaw sib txuas. Load break muaj peev xwm yog lub peev xwm los cuam tshuam lub Circuit Court yam tsis muaj teeb meem txhaum cai. Nws ua kom muaj kev nyab xeeb thiab yooj yim ntawm kev sib txuas ntawm cov khoom siv txuas nrog los ntawm cov khoom siv hluav taws xob rau kev kho lossis kho lub hom phiaj.
Fuse cutouts yog tsim los rhuav tshem cov load tam sim no yam tsis tau tsim ib qho arc, uas tuaj yeem ua rau cov khoom puas thiab ua rau muaj kev nyab xeeb. Los ntawm kev rhuav tshem cov khoom tam sim no, lub fuse cutout tso cai rau cov neeg ua haujlwm saib xyuas ua haujlwm ruaj ntseg ntawm cov cuab yeej txuas nrog yam tsis muaj kev pheej hmoo ntawm hluav taws xob lossis khoom puas tsuaj.
Tsis tas li ntawd, qee qhov fuse cutouts muaj qhov tshwj xeeb hu ua bypass hloov, uas tso cai rau qhov kev sib txuas ib ntus ntawm cov khoom thauj tom qab cais cov ntu tsis raug ntawm Circuit Court. Lub bypass hloov ua kom lub zog rov qab los rau qhov tsis muaj kev puas tsuaj ntawm qhov system thaum cov neeg ua haujlwm tu ua haujlwm ntawm qhov tsis raug.
Fuse cutouts yog siv dav hauv cov tshuab hluav taws xob, nrog rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Lawv yog ib qho tseem ceeb ntawm cov txheej txheem kev tiv thaiv, ua kom ntseeg tau thiab muaj kev nyab xeeb ntawm kev siv hluav taws xob.
Hauv ntiaj teb niaj hnub no, hluav taws xob hluav taws xob tuaj yeem ua rau muaj kev lag luam loj thiab cuam tshuam rau lub neej niaj hnub. Kev tiv thaiv los ntawm fuse cutouts pab txo qhov tshwm sim thiab cuam tshuam ntawm lub zog hluav taws xob los ntawm cov xwm txheej overcurrent. Yog tsis muaj fuse cutouts, lub zog faib hluav taws xob yuav raug cuam tshuam los ntawm kev puas tsuaj los ntawm overcurrents, ua rau muaj kev cuam tshuam ntev dua, kev puas tsuaj loj dua, thiab muaj kev nyab xeeb ntxiv.
Fuse cutout yog ib qho tseem ceeb ntawm lub zog faib hluav taws xob uas ua ob txoj haujlwm tseem ceeb: kev tiv thaiv overcurrent thiab load break peev xwm. Nws yog ib qho tseem ceeb ntawm qhov system tiv thaiv thiab ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov hluav taws xob network.
Kev xaiv kom raug thiab kev teeb tsa ntawm fuse cutouts yog qhov tseem ceeb los xyuas kom muaj kev tiv thaiv zoo. Fuse cutouts ua lub luag haujlwm tseem ceeb hauv kev muab cov kev pabcuam tseem ceeb thiab txhim kho lub neej zoo, ua rau lawv muaj txiaj ntsig zoo hauv kev lag luam hluav taws xob hluav taws xob.
