Kev siv thiab kho cov fuses

Hauv cov tshuab hluav taws xob tsawg, fuses yog ib hom khoom siv hluav taws xob uas ua lub luag haujlwm tiv thaiv kev nyab xeeb. Fuses tau dav siv rau kev tiv thaiv kab hluav taws xob thiab cov khoom siv hluav taws xob tiv thaiv. Thaum muaj kev cuam tshuam luv luv lossis overload tshwm sim hauv daim phiaj hluav taws xob lossis cov khoom siv hluav taws xob, lawv tuaj yeem txiav tawm hauv Circuit Court kom tsis txhob muaj kev puas tsuaj rau cov khoom siv hluav taws xob thiab tiv thaiv kev sib kis ntawm kev sib kis.
Lub fuse yog tsim los ntawm lub hauv paus rwb thaiv tsev (los yog cov khoom txhawb nqa), kev sib cuag, yaj, thiab lwm yam. Cov yaj yog qhov tseem ceeb ua haujlwm ntawm lub fuse. Lub yaj yog sib npaug rau ib qho tshwj xeeb ntawm cov hlau txuas nrog hauv series hauv ib lub voj voog. Thaum lub caij luv luv lossis overload tshwm sim hauv Circuit Court, qhov tam sim no siab dhau, thiab cov yaj melts vim overheating, yog li txiav tawm Circuit Court. Melts feem ntau ua rau hauv filaments, grids, los yog nplooj ntawv. Melt cov ntaub ntawv muaj cov yam ntxwv ntawm qhov tsawg melting point, ruaj khov yam ntxwv, thiab yooj yim melting. Feem ntau, txhuas-tin alloy, nyiaj plated tooj liab ntawv, zinc, nyiaj thiab lwm yam hlau yog siv. Thaum lub sij hawm txheej txheem ntawm melting thiab txiav tawm Circuit Court, ib tug arc yuav generated. Txhawm rau kom muaj kev nyab xeeb thiab ua tau zoo tua cov arc, cov yaj yog feem ntau ntsia rau hauv lub fuse vaj tse thiab kev ntsuas raug coj los tua cov arc sai.
Fuses muaj qhov zoo ntawm cov qauv yooj yim, siv tau yooj yim, thiab tus nqi qis, thiab tau siv dav hauv cov tshuab hluav taws xob tsawg.
