Lub tsheb hluav taws xob yog cov khoom lag luam siab kawg ua ke nrog cov khoom siv niaj hnub high-tech, high electronics, high material technology thiab manufacturing technology. Nws tso siab rau lub roj teeb fais fab los tsav tsheb thiab charger los ntxiv zog. Lub fuse yog lub luag haujlwm rau kev ua haujlwm ntawm ob lub zog sib txuas thiab kev tiv thaiv kev nyab xeeb hauv lub cev, uas cuam tshuam rau tag nrho kev nyab xeeb ntawm tsheb thiab tib neeg. Yog li ntawd, lub fuse rau kev tiv thaiv hluav taws xob tsheb yuav tsum yog DC hom millisecond precision khoom muaj peev xwm ntawm high-speed disconnection, Txwv tsis pub, thaum lub luv luv Circuit Court tam sim no tshwm sim, lub Circuit Court channel tsis tau sai thiab xyuam xim disconnected, kom lub luv luv Circuit Court tam sim no. tuaj yeem cuam tshuam ncaj qha rau lub roj teeb lossis rhuav tshem IGBT kev sib xyaw ua ke ntawm pawg inverter, thiab qhov kev puas tsuaj loj yog qhov tsis tuaj yeem xav txog.
Tom qab lub fuse txuas nrog hluav taws xob Circuit Court, lub fuse yog ib qho zoo heev conductor uas tsis tshua muaj kev tiv thaiv nyob rau hauv ib txwm load, tsuas yog siv ib tug me me ntawm hluav taws xob zog, thiab yuav ua hauj lwm stably nyob rau hauv ib tug ntev lub sij hawm nyob rau hauv lub hwj chim mov. Thaum lub overload txhaum tam sim no tshwm sim nyob rau hauv lub tshuab hluav taws xob, qhov tam sim no los ntawm lub fuse nce sai heev, thiab tam sim no qhov ceev los ntawm lub fuse nce sai heev, ua rau muaj kev kub ntxhov nyob rau hauv nruab nrab ntawm lub fuse. Thaum qhov kub nce mus txog qhov melting point ntawm lub fuse, lub fuse pib yaj los ntawm cov khoom mus rau cov kua, thiab tag nrho cov molten hlau nkag mus rau hauv ib puag ncig quartz xuab zeb sib txawv, yog li txiav tawm qhov txhaum tam sim no hauv Circuit Court. Tag nrho cov txheej txheem yuav siv li kaum vib nas this, vim hais tias lub fuse kuj qeeb los teb rau lub overload tam sim no, Feem ntau, Circuit Court breakers los yog thermal relays yog siv los tiv thaiv overload.
Thaum muaj qhov luv luv luv luv tam sim no hauv Circuit Court, qhov tam sim no dhau los ntawm qhov sib txuas fuse nce sai heev hauv lub sijhawm luv luv, ua rau lub caj dab nyias ntawm lub fuse txuas ncaj qha hlawv thiab vaporizing los ntawm cov khoom hauv lub sijhawm luv luv. , ua kom muaj zog daim phiaj arc ion roj, txwv txoj kev du ntawm qhov luv luv tam sim no, thiab tua sai sai thiab tshem tawm qhov kub thiab txias thiab high-voltage arc choj nyob rau hauv nruj ib puag ncig quartz xuab zeb thiab yuam kom txias, txiav tawm cov channel ntawm lub luv-circuit tam sim no, thiab ua tiav cov nyhuv ntawm kev nyab xeeb thiab high-ceev disconnection, tag nrho cov txheej txheem yuav siv sij hawm tsuas yog ob peb milliseconds.
Vim nws txoj haujlwm yooj yim, tsis tshua muaj nqi tsim khoom, thiab muaj kev nyab xeeb thiab kev ntseeg siab ntawm kev txwv qhov txhaum tam sim no, lub fuse yog cov khoom siv hluav taws xob zoo tshaj plaws rau kev tiv thaiv overcurrent, tshwj xeeb tshaj yog rau kev tiv thaiv luv luv. Tom qab lub sijhawm ntev ntawm kev siv thiab kev hloov pauv, nws tsis tau hloov thiab tshem tawm los ntawm kev hloov cov khoom siv, tab sis tau siv dav hauv kev lag luam niaj hnub thiab kev siv hluav taws xob hauv pej xeem.
