Bokosi la Fuse

Bokosi la fuse ndi mtundu wa mawotchi opangira magetsi , omwe ndi mtundu wolamulira wa magetsi onse a nyumba. Ngakhale nyumba iliyonse yomangidwa kuzungulira 1960 kapena pambuyo pake ili ndi gulu lokhala ndi magetsi oyendayenda, makapu m'nyumba zogona zakale zomwe zimagwiritsidwa ntchito ndi mafasho kuti apereke chitetezo chokwanira kwa maulendo apanyumba.

Bokosi la fuseti lili ndi mabotolo angapo omwe mafelemu amawombera ngati mababu a kuwala. Dera lililonse panyumba limatetezedwa ndi fuseti, ndipo fuseti iliyonse iyenera kukhala yoyenera komanso yoyenerera moyenerera pa dera lake. Kugwiritsa ntchito fuseti yoyipa pa dera kungapangitse ngozi yaikulu yamoto, choncho ndikofunika kudziwa fuse yoyenera pa dera lililonse.

Mabasi Opangira Fuse

Ma fuseti a maulendo oyenera (osati maulendo apamwamba othamanga) amatchedwa fus fuses ndipo ali ndi zida zowonongeka. Pali mitundu iwiri yosiyana ya mabungwe: maziko a Edison (omwe amapezeka pa mtundu wa T fuses) ndi maziko otsutsa (omwe amapezeka pa fesipi ya mtundu wa S).

Mzere wa Edison (Mtundu wa T) umawoneka ngati maziko a babu ndipo umagwirizana ndi zitsulo zomwe zimapezeka mabokosi akale a fuse. Tsamba la kukanidwa (Mtundu wa S) fuses idzagwira ntchito ndi zitsulo za Edison pokhapokha zitakhala ndi maziko a adapter omwe amawombera ndi kutseka m'dothi la Edison. Mtundu wa mtundu S ndiye amawongolera mu adapata.

Zolinga zotsutsa zimadziwikanso kuti "zowonongeka," ndipo zinapangidwa kuti zisawononge eni nyumba kuti asagwiritse ntchito fuseti yoyipa pa dera. Mtundu uliwonse wa mtundu wa S S wokupangidwira kwapadera kumakhala ndi adapotala yofanana ndi kukula kwa thread yomwe imalepheretsa kusokoneza mafayilo. Mwachitsanzo, amalepheretsa munthu kuyika fusemu 20 pampiringidzo 15-amphamvu, cholakwika chachikulu. Matendawa amatchedwa "over-fusing" ndipo angapangitse kuti fusele isalephere kuimbidwa mpweya wozungulira dera usanatenge moto.

Mtundu wa 15 amphamvu wa mtundu wa S umaphatikizapo adapitala ya mamita 15 okha. Mosiyana ndi zimenezi, mtundu wa fodya T ungagwirizane ndi zitsulo zilizonse za Edison, mosasamala kanthu za dera la dera. Ngati muli ndi bokosi lakale la fuse ndi mabotolo a Edison, kusintha kwa makina otengera ndi mawonekedwe a mtundu wa S amapangitsa gululo kukhala lotetezeka kwambiri.

Fuses-W Fuses

Mitundu ya W-mafayi ndi mawonekedwe akale a fuse pogwiritsa ntchito maziko a Edison ndipo onse ndi osatha masiku ano. Iwo ndi mafotolo omwe amagwiritsidwa ntchito mobwerezabwereza ndipo ndi "kuchita mofulumira" -ndiko, alibe nthawi yothandizira fuseti ndipo nthawi yomweyo amasokoneza dera kamodzi pamene fuse yomwe yawonetsedwa kuti yatha.

Ma fuseswa amapangidwa kuti azigwiritsidwa ntchito pa magetsi ndi magetsi omwe alibe magetsi. Mafakitale a magetsi amakoka zina zowonjezera pa kuyambira ndipo amavuta mtundu W Wopsereza ngati galimoto ili ndi kukula kwakukulu. Chifukwa cha ichi, fusasi yowonongeka imagwiritsidwa ntchito mochuluka kuposa mtundu wa W-fuses.

Zotsatira: 120 volts; mpaka ma 30 amps

Mtundu-SL ndi mtundu wa TL Fuses

Ma fuses ndi SL ndi T-medium-duty nthawi-kuchepetsa maferesi ndipo tsopano ndi maferesi omwe amapezeka kwambiri panyumba. Kusiyana kokha pakati pa SL ndi TL fusasi ndi mtundu wa maziko: SL fuse ili ndi maziko okanidwa, ndipo fulisi ya TL ili ndi maziko a Edison.

Ma fuses ndi SL ndi TL ali ndi pulasitiki yotentha yotentha yomwe imayikidwa pakati pa fuse element (gawo limene limatuluka, kapena "mphuno," pamsewu wambiri). Izi zimathandiza kuti fusezi ikhale ndi nthawi yambiri yozungulira yowonjezera, yomwe imayambitsa kupititsa patsogolo mwachangu pamene magalimoto ayamba. Popanda nthawi yowonongeka, kungoyamba kukonza zowonongeka kapena firiji kungachititse kuti fuselo liwombe.

Malingaliro: 120 volts; mpaka ma 30 amps

Mtundu-S ndi Mtundu-T Wolemera Nthawi-Mafilimu Ochedwa

Zida zowonongeka kwa nthawi zimagwiritsidwa ntchito pa maulendo ndi magalimoto oyendetsa kapena apamwamba kapena magalimoto oyendetsa magalimoto omwe nthawi zambiri amayendetsa (monga sump pump motor). Ma fuseswa amakhala ndi nthawi yochulukirapo kwambiri kuposa fusiti ya SL kapena TL. Komabe, mofanana ndi mafayilo a SL ndi TL, kusiyana kokha pakati pa S ndi T zowonjezera fusasi ndizowonjezera: mtundu-S uli ndi maziko otsutsa; mtundu-T uli ndi maziko a Edison.

Fusitasi yowonjezera nthawi yowonongeka ili ndi fusasi yowonjezera zitsulo yosungidwa ndi chitsime yomwe ili pamphuno ya solder. Ngati vuto la deta likuwonjezeka kwa nthawi yayitali, phula la solder limasungunuka ndipo kasupe amakoka chingwecho popanda mphamvu, kudula mphamvu ku dera. Izi zimapangitsa fuseti kutenga nthawi yochuluka yozungulira yambiri kuposa nthawi zina zochedwa fuses.

Malingaliro: 120 volts; mpaka ma 30 amps

Fuse Miniberaker

Anthu osokoneza bongo ndi ma fuses omwe amatha kusokoneza magetsi a Edison. Iwo amawombola m'malo mwa fuseti ndi phokoso lozungulira. Anthu osambira pang'ono amakhala ndi batani kakang'ono kamene kamatuluka pamene dera likulowetsa. Zonse zomwe mukufunikira kuchita ndizitsulola batani kuti mubwezeretsenso. Opuma pang'ono amapangidwanso kuti azichedwa kuchepa kotero kuti sapita mosafunikira pamene magalimoto kapena zipangizo zimayambira.
