Qhov kev tiv thaiv tawm ntawm rab phom tawm feem ntau yog 2kΩ, uas yog siv rau kev tawm mus kom muaj kev nyab xeeb tom qab them tas. Tus nqi tiv thaiv no yog tus nqi txheem, uas yog siv los txheeb xyuas lub xeev tawm thiab xyuas kom muaj kev nyab xeeb.
Cov lus piav qhia ntxaws:
Lub luag haujlwm ntawm qhov tso tawm resistor:
Lub luag haujlwm tseem ceeb ntawm lub resistor tso tawm yog kom tso tawm cov nqi hluav taws xob hauv lub capacitor lossis lwm yam khoom siv khaws cia hluav taws xob hauv rab phom them tom qab them tiav, kom tsis txhob muaj cov nqi hluav taws xob seem ua rau muaj kev phom sij rau tus neeg siv lossis cov khoom siv.
Tus nqi txheem:
Qhov kev tawm tsam ntawm qhovrab phom tua tawmfeem ntau yog 2kΩ, uas yog tus nqi txheem ib txwm muaj hauv kev lag luam.
Kev txheeb xyuas qhov tso tawm:
Tus nqi tiv thaiv no siv ua ke nrog lwm lub voj voog hauv rab phom them kom paub qhov xwm txheej tso tawm. Thaum lub resistor tso tawm txuas nrog lub voj voog, lub pawg them yuav raug txiav txim siab ua lub xeev tso tawm thiab pib cov txheej txheem tso tawm.
Kev lav phib xaub:
Qhov muaj lub resistor tso tawm ua kom ntseeg tau tias tom qab them tiav lawm, qhov them hauv rab phom tau raug tso tawm kom nyab xeeb ua ntej tus neeg siv rub rab phom them tawm, zam kev raug xwm txheej xws li hluav taws xob poob siab.
Cov ntawv thov sib txawv:
Ntxiv rau rab phom tso tawm tus qauv, muaj qee qhov kev siv tshwj xeeb, xws li BYD Qin PLUS EV lub charger hauv lub tsheb, uas nws lub resistor tso tawm yuav muaj lwm tus nqi, xws li 1500Ω, nyob ntawm tus qauv tsim hluav taws xob thiab cov kev xav tau ua haujlwm.
Kev tawm tsam tiv thaiv kev tawm tsam:
Qee cov phom tua hluav taws xob kuj muaj lub resistor qhia txog kev tua hluav taws xob sab hauv, uas, ua ke nrog lub micro switch, tuaj yeem siv los paub meej tias lub xeev tua hluav taws xob tau nkag mus tom qab rab phom them hluav taws xob txuas nrog kom raug.
Cov lus sib piv ntawm cov nqi tsis kam ntawmcov phom tua tawmraws li GB/T cov qauv
Tus qauv GB/T muaj cov kev cai nruj heev rau tus nqi tiv taus ntawm cov phom tua hluav taws. Tus nqi tiv taus ntawm CC thiab PE yog siv los tswj kev sib phim ntawm lub zog tso tawm thiab lub tsheb kom ntseeg tau tias muaj kev nyab xeeb ntawm kev siv hluav taws xob.
Lus Cim: Lub phom tua hluav taws tsuas yog siv tau yog tias lub tsheb nws tus kheej txhawb nqa lub luag haujlwm tua hluav taws.
Raws li Appendix A.1 ntawm nplooj ntawv 22 ntawm GB/T 18487.4, V2L tswj lub voj voog tsav thiab ntu tswj hwm ntawm A.1 muab cov kev cai tshwj xeeb rau qhov hluav taws xob thiab tam sim no ntawm kev tso tawm.
Kev tso tawm sab nraud yog muab faib ua DC tso tawm thiab AC tso tawm. Peb feem ntau siv cov khoom siv hluav taws xob ib theem 220V AC tso tawm yooj yim, thiab cov nqi tam sim no pom zoo yog 10A, 16A, thiab 32A.
63A qauv nrog peb theem 24KW tso zis: tso tawm phom tsis kam tus nqi 470Ω
32A qauv nrog ib theem 7KW tso zis: tso tawm phom tsis kam tus nqi 1KΩ
16A qauv nrog ib theem 3.5KW tso zis: tso tawm phom tsis kam tus nqi 2KΩ
10A qauv nrog ib theem 2.5KW tso zis: tso tawm phom tsis kam tus nqi 2.7KΩ
