Hom Fuses thiab Daim Ntawv Thov

Ntau hom fuses cuam tshuam ib qho dhau-tam sim no thiab tawg lub voj voog los ntawm melting lub fuse. Lawv feem ntau muab faib ua ob hom, AC fuse, thiab DC fuse. Tsis tas li ntawd, fuses tau muab faib ua ntau hom nyob ntawm qhov voltage thiab kev tsim kho. Lawv yog:
1.DC Fais Fab
DC fuses tsim ib qho arc uas nyuaj rau nres tshaj AC arcs vim tias tsis muaj xoom tam sim no ntws hauv Circuit Court. Rau kev txo cov DC fuse arcing cov electrodes tau muab tso rau ntawm qhov deb ntau vim qhov loj ntawm lub fuse nce raws li piv rau AC fuse.

2.AC Fuse
Hauv AC circuits, lub arc tua tau yooj yim thaum piv rau DC circuits. Vim tias qhov zaus ntawm AC fuses hloov nws qhov amplitude ntawm 0º mus rau 60º nyob rau hauv txhua txhua ob. AC fuse ntxiv tau muab faib ua ob pawg. Lawv yog cov tsis tshua muaj hluav taws xob fuses thiab high voltage fuses.

2.1 Tsawg Voltage Fuse
Tsawg voltage fuses muaj ntau heev nyob rau hauv cov tshuab hluav taws xob thiab lawv tuaj nyob rau hauv cov duab sib txawv thiab tsim. Tsawg voltage fuses muaj qhov ntsuas hluav taws xob tsawg dua lossis sib npaug li 1,500V.
2.1.1 Cartridge Hom Fuse (Tag nrho cov hom kaw)
Cartridge fuse muaj cov cua kub-tiv thaiv ceramic lub cev uas kaw los ntawm lub hau hlau ntawm ob qho kawg. Cov khoom ntim xws li chalk, plaster ntawm Paris, quartz lossis marble plua plav nyob ib puag ncig lub cev qhov chaw uas ua raws li qhov chaw arc quenching thiab txias nruab nrab. Feem ntau, lawv tau siv dav hauv kev lag luam, thaj chaw ua liaj ua teb thiab thaj chaw nyob xws li fuse panels, cua txias, twj, thiab khoom siv hauv tsev.

Cov hom fuses no tau muab faib ua D-hom thiab Link-type fuses.
D-hom fuse muaj lub nplhaib adapter, cartridge, puag, thiab cap. Lub hauv paus fuse txuas nrog lub fuse cap thiab lub cartridge yog khaws cia rau hauv lub fuse cap los ntawm lub nplhaib adapter. Lub Circuit Court tau ua tiav thaum qhov kawg ntawm lub cartridge ua rau kev sib cuag nrog tus neeg xyuas pib.
Link-type cartridge fuses tseem hu ua High Rupturing Capacity fuses (HRC). HRC fuse muaj lub peev xwm tawg siab. Nws muaj ob lub hlau xaus ntawm ob sab. Lub filling ntawm lub fuse nrog hmoov ntshiab quartz ua raws li ib tug arc extinguishing neeg sawv cev. Cov khoom siv fuse siv nyiaj los yog tooj liab rau nws qhov kev tsim kho.
Bolted fuse
Lub Hniav fuse tseem hu ua spade lossis plug-in fuse. Automotive OEMs siv lub fuse no rau lub tsheb tiv thaiv Circuit Court thiab tiv taus qhov kub thiab txias. Txawm li cas los xij, Bolt down fuse yog cov khoom tshwj xeeb tsim rau cov tsheb diesel thiab tsis tsim nyog rau cov tsheb thauj khoom.
