Hom fuses: los, hauj lwm, labeling

Fuses yog siv qhov txhia chaw - lawv yog cov nyob rau hauv lub kos duab nyob rau hauv ib tug ntau yam ntawm hluav taws xob pab kiag li lawm, tsheb, muaj khoom. Muaj ntau ntau hom ntawm cov ntsiab. Yuav ua li cas lawv xav tau thiab yog dab tsi lawv cov yam ntxwv? Xav txog lub ntsiab hom fuses.

feature

Fuse - ib tug generic lub sij hawm uas yog siv yog ruaj khov txaus nyob rau hauv electricians. Qhov no kom meej qhia kev tiv thaiv rau ntawm tej, cov khoom thiab hluav taws xob tes hauj lwm. Lub fuse yog ib tug switching khoom. Yuav ua li cas yog nws cov hom phiaj? Lub fuse yog tsim los tiv thaiv cov hluav taws xob network ntawm siab currents thiab luv luv circuits. Lub hauv paus ntsiab lus ntawm cov lag luam yog yooj yim heev kom paub meej - nyob rau hauv cov ntaub ntawv ntawm kev kawm ntawv overcurrent so yeej tsim no lub caij. Feem ntau qhov no fuse. Yog li ntawd txheej txheem tag nrho cov hom ntawm cov iav fuses.

Cov inserts - ib tug tseem ceeb, uas yog tsis tau tsis muaj txhua yam ntawm kev tiv thaiv cov ntsiab. Hauv nws kuj muaj ib tug tshwj xeeb tawg unit. Inserting lub fuses no yog ua los ntawm iav los yog fibreboard housings thiab tsau nyob rau hauv tshwj xeeb daim uas ua hluav taws xob. Hais tsim rau cov me dej tsaws ntxhee, thiab tej zaum yuav tsis muab rooj plaub no.

meltable

Qhov no yog feem ntau hom fuses rau siv nyob rau hauv lub tsev. Tej zaum qhov no yog ib lub xwb lub caij uas yog ib qho yooj yim mus kuaj rau serviceability. Ua li no, koj cia li yuav tsum tau saib nyob rau ntawm qhov kev nthuav dav ntawm clearance - nws yuav tsum tau pom lawm fusible txuas los yog tsis. Cov chaw no yog ua los rau hauv lub khob vaj tse nyob.

Fuse tej hub raj

Qhov no lub caij tsis txawv los ntawm cov iav khoom. Qhov txawv tsuas nyob rau hauv cov khoom ntawm lub plhaub. Tab sis yuav siv cov lus no yog tsis yog li ntawd xis - kev tshawb nrhiav "lub teeb" yog tsis tau tso tawm. Mus xyuas nws yog tsim nyog los siv ib tug tester los yog multimeter.

Fuse-txuas PVD

Cov fuses yog ua tau hauj lwm rau lub hauv paus ntawm lub tib lub hauv paus ntsiab lus. Tab sis cov qauv no yog hloov thiaj li mus saib tus txheej xwm ntawm cov khoom. Piv txwv li, yog ib tug lub caij yog cua tshuab, ces ib tug tshwj xeeb chij yuav tshwm sim nyob rau hauv lub rov qab ntawm cov khoom.

Hais nrog quartz xuab zeb

Cov fuses muaj siab arcing yam ntxwv. Tsim lawv nyob rau hauv ob lub versions: nyob rau hauv cov ntaub ntawv ntawm tej hub ntaub ntawv los yog iav Certificate. Feem ntau cov khoom no yog tsim los ua hauj lwm uas muaj currents. Tseem muaj ntau tshaj cov qauv. fuse ntaus ntawv muab ib tug ntau nthuav dav, qhov kev siv ntawm tej LDPE. Nws yuav tsum tau yuav tsum tau paub uas fuse yog cua tshuab.

Fast-acting fuses

Cov khoom uas yog tsis muaj dab tsi tshwj xeeb los ntawm tus so ntawm tib. Qhov txawv tsuas yog hais tias lub fuse yog hlawv sai sai heev thaum ib tug luv luv Circuit Court tshwm sim.

SMD

Cov khoom no yuav tsum muaj nyob rau hauv hluav taws xob pab kiag li lawm. Lawv yog cov heev me. Muaj nuj nqi thiab lub hom phiaj fuse - tiv thaiv cov khoom los ntawm siab currents uas lawv ua ib qho hauj lwm zoo heev.

Resettable

Nws yog heev nthuav daws teeb meem. Resettable fuse yog ib yam khoom, uas yog nyob rau hauv ib tug tshwj xeeb cov yas. Thaum yas insert yog txias, nws yuav ua hluav taws xob. Thaum lub insert yog sov mus rau ib tug tej yam kub, nws conductive khoom no poob vim ntau zog kuj. Tom qab txias, tam sim no muaj peev xwm dua ntws los ntawm cov khoom. Plus cov qhov chaw yog hais tias tom qab ib tug burnout tsis muaj yuav tsum tau rau lub caij hloov. Kev lag luam ua cov khoom nyob rau hauv ntau hom. Lawv yog tsim rau soldering ntawm attachments los yog nto mount technology. Nyob rau hauv kev, cov ntawm fuses siv nyob rau hauv muaj hwj huam circuits.

heev

Yog hais tias tag nrho cov saum toj no cov khoom txhua leej txhua tus paub, tus heev fuse - nws yog ib tug tsawg artist. Cov txheej txheem lus muab txaus burnout resonant suab. Tshwj xeeb heev ntaus ntawv, uas yog txuas mus rau lub conductive qhov chaw, cia li tawg. Lub luag hauj lwm rau no tshwj xeeb sensors. Tsis ntev los no saib xyuas tam sim no nyob rau hauv ib tug hluav taws xob Circuit Court. Qhov no yog ib tug heev muaj tseeb fuses, raws li lawv suab tsis yog nyob ntawm seb cov yam ntxwv ntawm cov hlau nyob rau hauv lub conductive qhov chaw. Qhov no lub caij nyob rau hauv lub tseeb ntawm qhov tam sim no sensor.

Lwm yam kev fuses

Mus ua hauj lwm nyob rau hauv ib tug high-voltage circuits siv tshwj xeeb Autogas, roj khoom, raws li zoo raws li cov ntsiab ntawm cov kua hom. Muaj txawm shooting tiv thaiv. lawv yuav tsis pom nyob rau hauv lub neej txhua hnub - yog ib tug kws haib khoom.

Labeling thiab npav

Txhua Chaw tsim tshuaj paus ua fuses rau ib code los yog ib feem tooj. Fuse tooj tso cai Wage mus nrhiav thiab qhia ntxiv rau specifications. Feem ntau, cov lis dej num yuav tsum muaj nyob rau hauv cov khoom. Tsis tas li ntawd, cov code yuav tau mus thov mus rau lub hlau ib feem. Tsis tas li ntawd cov lis dej num rau lub tsev nyob tej zaum yuav kuj qhia lub ntsiab cov ntaub ntawv - ib tug nyob tam sim no ib tug, ib tug me me voltage V dawm taw yam ntxwv los yog tsim nta. Lub ntawm fuses yuav txiav txim los ntawm cov ntaub ntawv no.

Yog li, lub nyob tam sim no muaj nqis - yog lub siab tshaj plaws muaj nqis nyob rau uas yam khoom ntawd yuav ua rau ib ntev lub sij hawm.

Nominal voltage - lub siab tshaj plaws permissible voltage uas qhov khoom securely lov rau hauv Circuit Court nyob rau hauv cov kev tshwm sim ntawm ib tug luv luv Circuit Court los yog overload rau lub network.

Rhuav muaj peev xwm hu ua ncov currents. Thaum lawv fuse yuav ua hauj lwm, tab sis nws lub cev yuav tsis raug puas tsuaj.

Cov yam ntxwv xa dependence nyob rau hauv lub sij hawm ntawm uas tus fuse caij los ntawm collapsing tam sim no uas ntws los ntawm cov khoom no. Ntau hom ntawm fuse yam ntxwv yog grouped rau hauv daim ntawv thov cov yam ntxwv thiab cov lus teb ceev. Feem ntau, cov yam ntxwv qhia hais tias kev ruaj ntseg nthuav dav. Siv rau xa mus rau cov tsiaj ntawv ntawm lub Latin niam ntawv. Thawj denoted tawg peev xwm. Yog li, G - yog ib tug tag nrho cov ntau yam, qhov khoom no puas tau los tiv thaiv lub Circuit Court thiab overload, thiab luv luv Circuit Court kev tiv thaiv. A - ib nrab ntau, thiab cov fuses tsuas tiv thaiv luv luv circuits.

Qhov thib ob tsab ntawv qhia txog lub hom chains:

• G - general hom phiaj Circuit Court.
• L - kev tiv thaiv ntawm cables thiab tis tshuab.
• M - Circuit Court kev tiv thaiv nyob rau hauv hluav taws xob motors.
• Tr - fuse muaj peev xwm tiv thaiv lub transformer network.

Hais nrog tsab ntawv R siv nyob rau hauv ua ke nrog hwj chim semiconductor khoom. Ib tug PV yuav muab kev tiv thaiv rau hnub ci hlwb.

Yog li ntawd, peb ntsia dab tsi yog qhov hom fuses thiab yuav ua li cas lawv npe lo rau.
