Lub tshuab hluav taws xob tso tawm yog cov cuab yeej siv hauv cov tshuab hluav taws xob los tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj vim hluav taws xob surges, luv Circuit Court, thiab lwm yam hluav taws xob tsis raug. Nws ua haujlwm los ntawm kev rhuav tshem cov hluav taws xob hluav taws xob thiab txo qhov ntws ntawm qhov tam sim no thaum muaj qhov tshwm sim dhau los lossis qhov teeb meem tshwm sim, cais qhov txhaum thiab tiv thaiv nws los ntawm kev sib kis.
Qhov kev tso tawm fuse feem ntau yog siv nyob rau hauv qis-voltage systems mus txog 36kV, xws li kev faib transformers, overhead kab, thiab underground cables. Nws muaj lub cev cylindrical plooj (porcelain) lub cev uas muaj ib lossis ntau lub fuse ua los ntawm cov nyiaj, tooj liab, lossis lwm yam khoom siv hluav taws xob. Lub cev plooj (porcelain) yog ntsia rau ntawm lub hauv paus steel thiab txuas nrog cov qauv kev txhawb nqa, xws li tus ncej lossis lub transformer.
Raws li kev ua haujlwm ib txwm muaj, lub fuse nyob rau hauv qhov kev tso tawm fuse nqa cov ntsuas tam sim no yam tsis muaj kev tiv thaiv, cia cov hluav taws xob hluav taws xob kaw. Txawm li cas los xij, thaum muaj teeb meem los yog overcurrent tshwm sim vim yog qhov ua rau sab hauv lossis sab nraud, lub fuse caij melts thiab tawg hluav taws xob Circuit Court.
Lub melting ntawm lub fuse lub caij yog tshwm sim los ntawm Joule cua sov nyhuv, uas tshwm sim thaum cov hluav taws xob tam sim no ntws los ntawm lub caij raws li tsis kam, ua rau ib tug nce nyob rau hauv kub thiab tshwm sim melting. Lub melting ntawm lub fuse caij ua rau lub porcelain lub cev ntawm lub fuse tawg, disconnecting faulty seem ntawm lub Circuit Court.
Lub dropout fuse kuj muaj kev tshem tawm haujlwm uas tshwm sim ib txhij nrog lub melting ntawm lub fuse caij. Qhov kev tshem tawm yog tsav los ntawm cov roj hluav taws xob siab uas tsim los ntawm arcing thaum lub sij hawm ua txhaum thiab tom qab melting ntawm lub fuse caij. Cov roj hluav taws xob siab no ua rau lub zog molten fuse, cov plooj (porcelain) lub cev, thiab lwm yam khib nyiab los ntawm bushing, tsim kom pom qhov pom thiab lub suab nrov. Qhov kev tshem tawm yog ib qho tseem ceeb ntawm qhov kev tso tawm fuse vim nws ua kom ntseeg tau tias qhov txhaum raug tshem tawm sai thiab tiv thaiv kev puas tsuaj ntxiv rau lub cev.
Muaj ntau hom kev tso tawm fuses tsim kom haum rau cov kev siv tshwj xeeb thiab kev ntsuas hluav taws xob. Qee qhov piv txwv suav nrog:
1. Sab hauv / Sab Nraud Dropout fuses- Cov no muaj nyob rau hauv ntau qhov kev ntsuas hluav taws xob, los ntawm 240V txog 36kV, thiab yog tsim los siv rau ob qho tib si sab hauv tsev thiab sab nraum zoov.
2. Cutout Dropout fuses- Cov no feem ntau siv nyob rau hauv cov khoom siv hluav taws xob thiab raug ntsuas ntawm qhov hluav taws xob mus txog 15kV.
3. Kev tshem tawm cov fuses- Cov no yog tsim los siv rau hauv cov ntawv thov uas yuav tsum muaj kev txhaum tam sim no, feem ntau hauv circuits uas muab cov khoom lag luam loj.
1. Kev ntseeg tau- Lub fuse tso tawm yog cov khoom pov thawj thiab txhim khu kev qha uas tau siv hauv kev lag luam fais fab rau ntau tshaj ib puas xyoo.
2. Tus nqi qis- Dropout fuses kuj pheej yig thiab yuav tsum tau saib xyuas tsawg.
3. Yooj yim rau nruab thiab hloov- Dropout fuses yog ib qho yooj yim rau nruab thiab hloov, ua rau lawv muaj kev xaiv nrov rau cov neeg cog lus hluav taws xob.
4. Kev tiv thaiv overcurrent- Lub dropout fuse muab kev tiv thaiv overcurrent zoo heev, txo qhov kev pheej hmoo ntawm kev puas tsuaj rau cov khoom siv hluav taws xob thiab txo qis sijhawm.
Dropout fuse yog qhov tseem ceeb thiab txhim khu kev qha ntawm cov tshuab hluav taws xob, muab kev tiv thaiv overcurrent thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj rau cov khoom siv. Nrog nws cov nqi-zoo, yooj yim ntawm installation thiab hloov, thiab cov ntaub ntawv pov thawj, nws tau dhau los ua kev xaiv nrov rau cov neeg ua haujlwm hluav taws xob thiab cov kws tsim khoom. Raws li cov tshuab hluav taws xob tau dhau los ua qhov nyuaj thiab nyuaj, qhov kev tso tawm fuse yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev ua kom lawv txoj kev nyab xeeb thiab kev ntseeg tau.
