Muaj pes tsawg Joules rau Surge Protector? Ib Phau Ntawv Qhia Txog Kev Yuav Khoom Tag Nrho
Xyoo tas los kuv kib lub CNC board uas muaj nqis $3,000 vim kuv pheej yig dua li 200-Joule strip; lub ntxhiab tsw tseem ua rau kuv sawv.
Ib lub tshuab tiv thaiv hluav taws xob zoo pib ntawm 600 Joules rau cov khoom me me thiab nce dhau 2,000 Joules rau cov servers lossis CNC tshuab. Txuas tus lej rau tus nqi ntawm qhov koj ntsaws rau hauv.
Hauv qab no kuv piav qhia cov lej tseeb uas koj xav tau, vim li cas qhov kev ntsuas thiaj tseem ceeb, thiab kuv tam sim no qhia txog cov strips rau kuv tus kheej cog li cas kom koj tuaj yeem theej daim ntawv thiab tsis txhob poob ib lub rooj tsavxwm dua.
Vim li cas koj yuav tsum tau saib xyuas txog qhov Kev Ntsuas Joule?
Muaj ib zaug kuv tsis quav ntsej txog "Joules" ua ib qho kev lag luam tsis tseem ceeb - txog thaum ib qho kev nce siab tsuas yog tshem tawm ib lub lim tiam ntawm kev tsim khoom thiab ua rau kuv raug nplua rau kev thauj khoom los ntawm huab cua.
Yog tias qhov ntsuas Joule qis dhau, daim kab xev yuav tuag tom qab ib zaug ntaus thiab koj lub tshuab tseem noj cov spikes. Xaiv tus lej raug thiab tib daim kab xev yuav nqus tau qhov ntaus tom qab ntaus tau ntau xyoo.
Ua ntej kuv yuav ib lub thawv uas muaj cov kab txaij, kuv yuav tsum ua tib zoo saib seb puas muaj kev pheej hmoo: sau txhua yam khoom siv uas nyob hauv lub rooj zaum, sau nws tus nqi hloov, tom qab ntawd ntxiv 20% ntawm qhov kev nyab xeeb. Daim ntawv qhia yooj yim ntawd qhia kuv tias qhov tsawg kawg nkaus Joules uas kuv tuaj yeem txais tau. Yog tias cov qauv ntawm lub Hoobkas muaj tus lej ntawd, kuv yuav tsis lees txais cov khoom ntawd - tsis muaj email thib ob, tsis muaj kev sib tham. Kuv tau kawm los ntawm txoj kev nyuaj tias cov kab txaij pheej yig dua $ 0.50 tuaj yeem rho tawm qhov kev txiav txim $ 50,000.
Joules Ua Haujlwm Li Cas Hauv Lub Neej Tiag
Xav txog Joules zoo li lub tank roj hauv koj lub tsheb. Lub tank 500-Joule tuaj yeem nqus tau 500 "units" ntawm lub zog spike ua ntej cov hlau-oxide varistors (MOVs) hlawv tawm. Lub tank 2,000-Joule kav ntev dua plaub npaug hauv qab tib lub spikes. Kev suav lej yog linear, yog li kuv khaws daim ntawv qhia txog kev dag ntxias rau ntawm kuv lub rooj:
| Hom Khoom Siv | Qhov Loj ntawm Cov Ncej Loj | Cov Joules Muaj Kev Nyab Xeeb |
| Lub xov tooj them fais | 50 J | 300 J |
| Lub PSU ntawm lub laptop | 150 J | 600 J |
| 3-axis CNC pawg thawj coj saib xyuas | 400 J | 1,800 J |
| PSU ntawm lub server | 600 J | 2,500 J |
Tus nqi zais ntawm "Tsuas Yog Txaus" Joules
Cov neeg yuav khoom nyiam siv nyiaj tsawg kawg nkaus ntawm BOM, tab sis ib daim kab hluav taws xob uas tuag tom qab ib zaug ntaus yuam kom koj rhuav thiab hloov thaum lub sijhawm kho tom ntej. Lub sijhawm tsis ua haujlwm ntawd tuaj yeem kim dua li tag nrho cov peev nyiaj tiv thaiv hluav taws xob. Tam sim no kuv teev tsawg kawg yog ob npaug ntawm Joules uas tau xam kom daim kab hluav taws xob muaj sia nyob kom txog thaum lub sijhawm kaw tom ntej.
Joules ntawm Surge Protector yog dab tsi?
Kuv tseem nco qab lub ntsej muag ntawm kuv tus neeg muag khoom thaum kuv hais kom nws qhia kuv cov lej MOV tiag tiag - nws paub tias qhov kev ua si tau xaus.
Joules yog tag nrho lub zog uas lub pob MOV tuaj yeem nqos ua ntej nws luv. Nyeem daim ntawv nplaum UL, tsis txhob nyeem cov ntawv tuab ntawm sab xub ntiag, vim tias qee lub npe ntxiv cov lej ntawm peb MOVs txawm tias tsuas yog ib txoj kev ua haujlwm xwb.
Hauv txhua daim kab koj yuav pom ib lossis ntau daim disc xiav uas loj li ib feem plaub. Cov ntawd yog MOVs. Lawv txoj kab uas hla thiab tuab teeb tsa qhov ntsuas zog, tsis yog lub tsev yas. Kuv xav tau daim disc 14 hli rau 1,000 Joules thiab 20 hli rau 2,000 Joules. Yog tias lub Hoobkas xa cov disc 10 hli, kuv taug kev tawm.
MOV Txoj Kab uas hla vs. Lub Rooj Zog
| Txoj kab uas hla ntawm lub disc | Cov Joules Ib Txwm Muaj | Lub voj voog ntawm lub neej ntawm 500 J hits |
| 10 hli | 400 J | 1 |
| 14 hli | 1,000 J | 2 |
| 20 hli | 2,000 J | 4 |
| 34 hli (2 daim) | 3,000 J | 6 |
Vim Li Cas Qee Cov Kev Ntsuas Dag
Ib qho kev dag ntxias yog txuas peb lub MOVs kab-rau-nruab nrab, kab-rau-av, thiab nruab nrab-rau-av, tom qab ntawd ntxiv lawv cov qib ntsuas. UL tsuas yog suav txoj kev me tshaj plaws xwb, yog li tus lej tiag tiag yog ib feem peb ntawm lub npe. Kuv ib txwm thov daim ntawv qhia kev xeem UL 1449 thiab ua ib lub voj voog rau qhov ntsuas ib qho. Yog tias tus neeg muag khoom tsis kam, kuv rho tawm cov lus hais.
Xav tau pes tsawg Joules rau ntau yam xwm txheej sib txawv?
Kuv khaws daim npav laminated hauv kuv lub hnab nyiaj hla tebchaws nrog Joule specs tseeb rau txhua yam khoom uas kuv yuav; cov neeg ua haujlwm hauv kev lis kev cai xav tias kuv coj txawv txawv, tab sis kuv cov lus tsis poob qis.
Siv 600 J rau xov tooj thiab teeb, 1,000 J rau cov tshuab luam ntawv, 1,500 J rau TV, thiab 2,000 J lossis ntau dua rau txhua yam uas kim dua koj cov nyiaj hli txhua hli.
Txoj cai yooj yim: hloov tus nqi faib los ntawm kaum sib npaug qhov tsawg kawg nkaus Joules. Lub ntsuas $ 200 xav tau 200 J yam tsawg kawg nkaus, tab sis kuv ntxiv 50% chav rau kev laus. Qhov luv luv ntawd yeej tsis tau ua rau kuv poob siab.

Cov Ntaub Ntawv Ntug Uas Tib Neeg Tsis Nco Qab
Cov tsav tsheb tsav tsheb pov rov qab EMF spikes uas tuaj yeem yog ob npaug ntawm txoj kab hluav taws xob. Kuv ib txwm ob npaug ntawm Joule qhov ntsuas thaum lub nra hnyav yog inductive. Cov roj teeb chargers yog lwm qhov ntxiab - lawv zoo li tsis muaj teeb meem, tab sis cov khoom siv hloov pauv tuaj yeem pov 800 J rov qab rau hauv txoj kab thaum lub relay qhib. Kuv poob $ 900 oscilloscope li ntawd; tam sim no txhua lub rooj sib tw kuaj tau txais yam tsawg kawg nkaus 1,500 J.
Vim li cas qhov kev ntsuas Joule siab tseem ceeb rau koj cov khoom siv hluav taws xob
Hnub uas kuv txoj kab xaiv thiab tso khoom tsis ua haujlwm lawm, kuv muaj 12 tus neeg ua haujlwm sawv tsis ua haujlwm ntawm $ 80 ib teev twg—$ 960 ib teev vim tias daim kab hluav taws xob 400-Joule tsis ua haujlwm lawm.
Cov kab txaij High Joule ua haujlwm zoo li daim txhuam cev loj dua; lawv nqus cov suab nrov rov qab kom koj lub tshuab ua haujlwm tas li thiab koj cov lus thov lav tsis hloov pauv.
Txhua lub qhov hluav taws xob loj ua rau MOV hnav me ntsis. Ib lub tshuab hluav taws xob 500-Joule tuag tom qab ib lub tshuab hluav taws xob 400-Joule raug, tab sis ib lub tshuab hluav taws xob 2,000-Joule tsis cuam tshuam plaub lub tshuab hluav taws xob zoo ib yam. Qhov ntawd txhais tau tias koj hloov cov hlua hluav taws xob thaum lub sijhawm teem tseg tom ntej, tsis yog thaum muaj xwm txheej ceev.

Kev suav lej yeej nyuaj heev: txuag tau $1.60 ua ntej yuav raug nqi ob txhiab daus las tom qab. Kuv tus CFO thaum kawg tsis sib cav lawm thaum kuv qhia daim ntawv no rau nws.
Daim Duab Ua Tsis Tau Zoo Hauv Ntiaj Teb Tiag Tiag Kuv Khaws Cia
Kuv muab ib daim kab xev 600-Joule uas tawg lawm lo rau ntawm daim ntawv tshaj tawm ze ntawm lub moos. Daim MOV tawg zoo li lub ncuav qab zib thiab ua rau daim yas kub hnyiab. Nyob ib sab ntawm nws yog ib daim kab xev 3,000-Joule uas raug xob laim tib yam thiab tseem zoo sim. Tsis tas yuav hais lus; daim duab ua qhov kev cob qhia.
Muaj pes tsawg Joules yog tus tiv thaiv Surge zoo?
Kuv hais rau txhua tus neeg yuav khoom tshiab tib kab lus: "Zoo pib ntawm 1,000 Joules thiab nce mus txog thaum tus nqi tsis mob ntau dua li lub sijhawm tsis ua haujlwm."
Ib lub cuab yeej tiv thaiv hluav taws xob zoo muaj tsawg kawg yog 1,000 Joules, daim ntawv pov thawj UL 1449, thiab lub zog clamping qis dua 400 V. Txhua yam qis dua yog lub hwj chim strip, tsis yog kev tiv thaiv.
Kuv khiav ib daim ntawv teev kawg ua ntej kuv kos npe rau PO: UL cov ntaub ntawv tus lej, ib qho taw tes Joule ntsuas, 14 hli MOV yam tsawg kawg nkaus, thiab 100 kA luv luv-circuit xeem. Yog tias lub Hoobkas kuaj xyuas tag nrho plaub, daim kab xev tau txais kuv lub logo thiab tsib xyoos warranty.
