Tua tawm fuse yog kab kab ntawm 10 kV cov kab xa tawm thiab cov xa hluav taws xob xa hluav taws xob feem ntau siv hluav taws xob tiv thaiv luv luv. Nws muaj kev lag luam, ua haujlwm yooj yim, hloov pauv mus rau ib puag ncig sab nraum zoov nrog cov yam ntxwv muaj zog, tau siv dav hauv 10kV cov kab xa khoom thiab cov xa hluav taws xob faib ua ib sab raws li kev tiv thaiv thiab khoom siv, ua haujlwm nrog. Nws tau teeb tsa hauv 10kV kev faib khoom faib kab kab, txo lub zog hluav taws xob, vim tias nws muaj qhov pom kev cuam tshuam tsis zoo, muaj kev ua haujlwm ntawm kev sib cais, tsim kom muaj kev nyab xeeb ua haujlwm ib puag ncig rau kev saib xyuas kab thiab khoom siv, ua rau muaj kev nkag siab zoo ntawm kev nyab xeeb ntawm cov neeg ua haujlwm tu. Txhim kho ntawm kev faib hluav taws xob xa hluav taws xob, tuaj yeem siv los ua kev tiv thaiv tseem ceeb ntawm kev faib hluav taws xob xa hluav taws xob, yog li, hauv 10kV cov kab xa khoom thiab cov xa hluav taws xob xa tawm tau nrov.
Nws txoj haujlwm ua haujlwm yog: fuse raj ntawm ob qho kawg ntawm kev sib chwv txav mus txuas rau lub fuse (yaj), kev sib cuag txav thawb "duckbill" bulge, phosphorus, tooj liab phaj, thiab lwm yam. yog li lub fuse raj khov kho clamped ntawm "duckbill". Thaum qhov hluav taws xob luv luv tam sim no dhau los ntawm lub fuse tau tshuab tawm, arcing, fuse raj hauv ob sab phlu vulcanized fiber raj nyob rau hauv cov nyhuv ntawm arc tsim cov pa roj ntau vim yog qhov kawg ntawm cov yeeb nkab fuse raug thaiv, roj mus rau qhov kawg kawg ntawm cov tshuaj tsuag. , tshuab tawm lub arc. Vim yog fuse, fuse raj txav mus fuse txuas lub zog poob, lub fuse raj zoo li qub hu rau lub caij nplooj ntoo hlav ntawm tus kheej lub ntiajteb txawj nqus, thiab hauv qab, fuse raj poob sai, lub Circuit Court txiav tawm, tshem tawm ntawm qhov ua txhaum ntawm kab lossis cov khoom siv tsis ua haujlwm.
