Kev ua haujlwm ntawm kev tso tawm fuse

Qhov kev tso tawm fuse yog luv luv-circuit tiv thaiv hloov pauv dav siv hauv 10kV faib kab kab kab thiab faib cov khoom siv hluav taws xob. Yog li dab tsi yog nws cov haujlwm tshwj xeeb?
Lub luag haujlwm ntawm kev tso tawm fuse:
Lub luag haujlwm tshwj xeeb ntawm kev tso tawm fuse yog yuav tsum tau muab tso rau ntawm ceg kab ntawm 10kV faib kab, uas tuaj yeem txo qhov kev siv hluav taws xob tawm. Vim tias nws muaj qhov pom tseeb ntawm kev sib txuas thiab muaj kev ua haujlwm ntawm kev hloov pauv, nws tsim kom muaj kev nyab xeeb rau cov kab thiab cov khoom siv hauv kev saib xyuas. Qhov chaw ua haujlwm nce kev nkag siab ntawm kev ruaj ntseg rau cov neeg ua haujlwm tu. Nruab rau ntawm lub transformer tis, nws kuj tseem siv tau los ua kev tiv thaiv tseem ceeb ntawm kev faib transformer. Yog li ntawd, nws tau nrov nyob rau hauv 10kV faib kab thiab faib transformers.
Lub hauv paus ntsiab lus ntawm kev tso tawm fuse:
Cov kev txav mus los ntawm ob qho kawg ntawm lub fuse raj yog fastened los ntawm fuse (melt). Tom qab kev sib cuag sab saud raug thawb mus rau hauv qhov protruding ntawm "duckbill", lub sab sauv zoo li qub ua los ntawm phosphor bronze ntawv, thiab lwm yam, presses tiv thaiv sab sauv kev sib cuag. lub taub hau, yog li lub fuse raj yog ruaj khov nyob rau hauv "duckbill". Thaum lub luv luv-circuit tam sim no tshuab los ntawm lub fuse, ib tug arc yog generated. Cov hlau ntawv raj lined nrog lub fuse tube ua rau muaj roj ntau nyob rau hauv qhov kev txiav txim ntawm lub arc. Vim tias qhov kawg ntawm lub raj fuse yog kaw, cov pa roj tau tawm ntawm qhov kawg, tshuab tawm lub arc. Vim hais tias lub fuse yog tshuab, lub sab sauv thiab qis txav ntawm lub fuse raj poob lub fuse zawm quab yuam. Nyob rau hauv qhov kev txiav txim ntawm lub fuse raj nws tus kheej lub ntiajteb txawj nqus thiab lub sab sauv thiab sab static contact springs, lub fuse tube ntog sai heev, ua rau lub Circuit Court yuav tsum tau disconnected. , tshem tawm cov faulty seem ntawm kab los yog faulty khoom.
