Raws li lub hauv paus tseem ceeb ntawm kev ruaj ntseg hluav taws xob, high voltage fuses yog haum rau cov xwm txheej hauv qab no. Cov qauv tsim thiab kev ua haujlwm ntawm high voltage hluav taws xob system uas yog ze ze rau lub zog tshiab tsheb yuav tsum tau:
I. Core Protection Scenarios
Main Circuit Court tiv thaiv
Roj teeb them- kev tiv thaiv tawm: Yog tias qhov tam sim no tshaj qhov kev nyab xeeb (xws li kev ua haujlwm tsis tu ncua lossis luv luv) thaum lub roj teeb them nqi - cov txheej txheem tawm, qhov siab -voltage fuse yuav yaj sai, tiv thaiv lub roj teeb los ntawm overheating, ntes hluav taws lossis tawg. Piv txwv li, thaum lub roj teeb tswj qhov system pom qhov txawv txav tam sim no, lub fuse tuaj yeem txiav lub voj voog hauv milliseconds los tiv thaiv kev puas tsuaj rau lub roj teeb pob.
Tsav hluav taws xob tiv thaiv: Tus tswj lub cev muaj zog ntawm lub tsheb hluav taws xob (xws li lub inverter) yuav tsum ua kom muaj zog tam sim no. Fuses tuaj yeem tiv thaiv lub cev tsis muaj zog, luv luv Circuit Court thiab lwm yam kev ua txhaum uas tshwm sim los ntawm kev hloov pauv tam sim no, thiab tiv thaiv lub cev muaj zog thiab tswj kev puas tsuaj.
Pab tiv thaiv Circuit Court
Cua txias System: High voltage fais fab mov yuav tsum tau rau compressors, PTC rhaub thiab lwm yam khoom pab rau cov hluav taws xob tsheb. fuses tiv thaiv luv luv - Circuit Court tam sim no los ntawm cov khoom siv tsis ua haujlwm los ntawm kev cuam tshuam rau tag nrho lub tsheb hluav taws xob.
DC / DC converter: Thaum hloov hluav taws xob siab DC mus rau qhov tsis tshua muaj hluav taws xob DC (xws li them aa 12V roj teeb), lub fuse tiv thaiv lub converter los ntawm kev puas tsuaj los ntawm ib qho luv luv Circuit Court lossis overload ntawm lub input / output terminals.
Charging system: Thaum them ceev lossis them qeeb, lub fuse tuaj yeem tiv thaiv luv luv lossis overload ntawm pawg them lossis lub tsheb charger tshwm sim los ntawm qhov hluav taws xob hluav taws xob tsis ua haujlwm, kom muaj kev nyab xeeb.
High voltage hlau hlua tiv thaiv
Yog hais tias lub siab -voltage hlau hlua nyob rau hauv ib lub tsheb fais fab (xws li cable txuas lub roj teeb, lub cev muaj zog thiab lub chaw nres nkoj them) luv luv - Circuit Court vim kev laus, hnav lossis cuam tshuam, lub fuse tuaj yeem txiav tam sim no sai los tiv thaiv cov hlua hlau los ntawm kev ntes hluav taws lossis ua rau muaj kev puas tsuaj rau lwm yam khoom.
II. Kho kom haum rau cov xwm txheej tshwj xeeb
800V siab -voltage platform
Thaum lub tsheb hluav taws xob tau hloov kho mus rau qhov hluav taws xob hluav taws xob ntawm 800 V lossis siab dua, lub siab -voltage fuse yuav tsum muaj siab ntau dua -tiv taus (feem ntau yog npog 500V-1000V) thiab tawg tau (txog 10 kA) los tiv thaiv qhov hluav taws xob luv luv. Hauv 800V qhov system, piv txwv li, lub fuse yuav tsum tau txiav ntau txhiab amperes ntawm hluav taws xob thaum lub sij hawm luv luv los tiv thaiv lub kaw lus ntawm kev sib tsoo.
High Frequency Pulse Tolerance
Siab - zaus tam sim no pulses yog tsim thaum lub cev muaj zog pib thiab roj teeb tsub thiab tawm. fuses yuav tsum muaj kev poob siab tiv thaiv kom tsis txhob muaj cov fuses cuav tshwm sim los ntawm cov mem tes tam sim no. Piv txwv li, yog tias lub cev muaj zog pib thiab nres ntau zaus, lub fuse yuav tsum tiv taus luv luv - lub sij hawm overload yam tsis muaj kev puas tsuaj.
Kho kom haum rau cov xwm txheej hnyav
Kub adaptability: Fuses yuav tsum ua haujlwm tsis tu ncua nyob rau hauv ntau qhov kub thiab txias ntawm -40℃txog 85 degree, yoog rau cov xwm txheej hnyav xws li kev them nyiaj kub kub thiab tsis kub pib.
Kev co thiab kev cuam tshuam: Kev co thiab kev cuam tshuam ntawm lub tsheb hluav taws xob thaum lub sijhawm ua haujlwm yuav ua rau muaj kev ntxhov siab rau lub fuse, uas yuav tsum tau tiv thaiv los ntawm kev tiv thaiv- kev co tsim.
III. Daim ntawv thov
Tsheb neeg nrog caij
Lub zog tshiab cov neeg caij tsheb feem ntau xav tau plaub mus rau 8 qhov siab -voltage fuses los tiv thaiv lub ntsiab Circuit Court (xws li roj teeb, lub cev muaj zog), pab cuam Circuit Court (xws li cua txias, DC / DC) thiab them nyiaj.
Cov tsheb lag luam
Lub zog tshiab kev lag luam thiab cov tsheb tshwj xeeb xav tau ntau lub fuses (piv txwv li, 8-16) vim lawv xav tau lub zog ntau dua. Piv txwv li, lub tshuab hluav taws xob high-voltage rau lub tsheb fais fab tuaj yeem muaj lub ntsiab fuse, lub fuse fuse thiab them fuse, tsim cov txheej txheem tiv thaiv.
Charge pawg
Cov zis kawg ntawm DC charging pawg yuav tsum tau nruab nrog lub siab voltage fuse los tiv thaiv lub charging module thiab lub tsheb them chaw nres nkoj.
