Muaj cov ris tsho yog cov khoom siv hluav taws xob siv nyob rau hauv cov chaw muaj kev muaj nrog cov khoom muaj peev xwm loj tam sim no thiab dej tsis txaus. Hauv tsab xov xwm no, peb yuav qhia cov qauv kev lag luam tshwj xeeb ntawm kev nthuav dav hauv kev nthuav dav, suav nrog cov chaw nyob hauv ntiaj teb, cov chaw muaj feem xyuam thiab lwm yam.
I. Cov Qauv Thoob Ntiaj Teb
Tam sim no, International Reverence Industrial Cov qauv muaj feem ntau yog cov hauv qab no: IEC 60309, NEMA, BS En 60309, AS / NZS 3123 thiab lwm yam. Cov qauv no yog siv rau hauv thaj tsam sib txawv nrog cov qauv sib txawv thiab cov yam ntxwv. Hauv qab no peb qhia cov qauv no ib qho los ntawm ib qho.
1.IJ 60309
IEC 60309 yog ib qho kev lag luam plug thiab ntsaws cov tawv txheem tsim los ntawm International ElectroteCort Commission. Nws muaj ntau yam nyob rau qib tam sim no xws li 16a, 32a, 63a, 125A, 250A thiab yog li ntawd, uas siv rau hauv cov chaw sib txawv. Hom Generals cov hom yog 2P + E, 3P + E, 3P + E, uas tau qhia tau nrog rau cov av, tsis muaj av thiab nrog nruab nrab.
2.NAS
Nema yog ib qho kev lag luam ntsaws thiab ntsaws cov txheej txheem tsim los ntawm cov koom haum hluav taws xob koom nrog. Nws siv cov txheej txheem polarized uas tiv thaiv cov ntsaws ntawm ntsaws ntawm muab tso rov qab thiab tsis raug. Cov qauv xws li NEMA L5, NEMA L7, NEMA L15, thiab lwm yam yog ib qho ntsaws, thiab L15 yog 30a / 250V ntsaws.
3.bs en 60309
BS En 60309 yog tus qauv rau kev lag luam plugs thiab cov thom khwm tsim los ntawm Europeannic tuam tsev, tseem hu ua tus qauv CEE. Nws zoo ib yam li IEC 60309 tab sis txawv rau qee qhov tsis sib xws. Hom Cov Khoom Siv Ntaus Nruag yog 16A, 32a, 63a, 125A, thiab lwm yam uas haum rau cov khoom ntim sib txawv.
4.SAS/NZS 3123
AS / NZS 3123 yog ib qho kev lag luam plug thiab ntsaws (cov txheej txheem tsim tsim los ntawm Australia thiab New Zealand. Nws siv cov qauv zoo sib xws rau NEMA qauv, uas tiv thaiv kev nkag tsis raug. Cov qauv ib txwm muaj yog 10A thiab 15a, uas haum rau cov khoom siv nrog lub zog sib txawv.
Ii. Rating tam sim no thiab plug hom
Qhov kev ntsuam xyuas tam sim no ntawm kev lag luam trackety yog qhov siab tshaj plaws tam sim no uas lub qhov (socking) tuaj yeem tiv taus. Raws li cov teb chaws sib txawv thiab cov cheeb tsam, qhov ntsuas tam sim no ntawm kev lag luam kab sib txawv, feem ntau suav nrog 16a, 32a, 63a, 250A kev ntaus nqi. Qhov siab dua qhov kev ntsuam xyuas tam sim no, ntau dua cov ntsaws lub ntswj tuaj yeem tiv taus.
Cov hom kev lag luam plug kuj sib txawv kuj sib txawv raws li cov qauv sib txawv. Common plug types are 2P+E, 3P+E, 3P+N+E, etc. 2P means two polarity pins, E means with ground, 3P means three polarity pins, N means with neutral. Hom sib txawv yog tsim rau cov kev sib txuas sib txuas sib txuas.
III. Muaj Qhov Chaw Siv Tau
Kev lag luam sab hauv yog qhov tsim nyog rau ntau qhov chaw muaj kev lag luam, suav nrog cov chaw tsim khoom, kev cob qhia, pov tseg, cov nkoj, mines thiab li ntawd. Vim nws cov plua plav, dej thiab lwm yam ntxwv, muaj steepperasal yog feem ntau siv nyob rau hauv ib puag ncig sab nraum zoov thiab hnyav. Raws li cov kev xav tau ntawm cov chaw sib txawv, kev lag luam sab hauv kuj tseem tuaj yeem nruab nrog tawg {}} {4 4} {{5} {tiv taus nta.
IV. Cov kev ceev faj
Thaum siv cov sockets, koj yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:
- Cov ntsuas ntsuas ntsuas qhov ntsuas tam sim no thiab cov chav ntsaws yuav tsum raug xaiv raws li lub nra tiag tiag los ua kom muaj kev nyab xeeb thiab kev ntseeg tau.
- Nquag khij lub rwb thaiv tsev ntawm lub qhov (socket) kom tiv thaiv kom tsis txhob to feakage thiab lwm yam teeb meem kev nyab xeeb.
- Thaum siv, plugs yuav tsum tau muab tso tawm kom raug thiab tshem tawm kom tsis txhob plug ua kom tso tawm rov qab los yog tsis raug rau kev tsis taus hluav taws xob tsis ua haujlwm.
- Tsis tu ncua tswj thiab ntxuav lub qhov (socket) kom tshem tawm cov hmoov av thiab kev cuam tshuam kom ntseeg tau tias ua haujlwm zoo ntawm lub).
Ntsiab lus:
Kab lus no piav qhia cov qauv cov kev lag luam ntawm kev lag luam cov khaub ncaws hauv kev nthuav dav, suav nrog cov chaw nyob tam sim no, ntsaws cov chaw thiab cov chaw muaj feem. Kev xaiv cov sockets yuav tsum tau ua raws li kev xav tau tiag tiag thiab kev nyab xeeb.
