Cov hluav taws xob hauv tsev feem ntau yog ib zaug -theem 220V, thaum cov ntawv thov kev lag luam feem ntau siv peb -theem 380V. Txawm li cas los xij, qhov hluav taws xob tsim los ntawm lub tshuab hluav taws xob cog hluav taws xob tsis yog ntawm ob qho no. Yog li, pes tsawg volts puas lub tshuab hluav taws xob tsim hluav taws xob tiag tiag?
1. Lub tshuab hluav taws xob tsim hluav taws xob muaj pes tsawg volts?
Lub tshuab hluav taws xob tso zis hluav taws xob yog txiav txim siab los ntawm chav tsev muaj peev xwm, rwb thaiv tsev tsim, thiab daim phiaj sib raug zoo. Qhov ntsuas tso zis voltage ntawm mainstream generators nyob rau hauv Suav teb tau muab faib ua cov theem hauv qab no:
| Cov khoom me me thiab nruab nrab- qhov loj me ntawm cov khoom tsim (hydropower, cogeneration) | 6.3 kV, 10.5 kV |
| Loj thiab nruab nrab - qhov loj thermal fais fab units (300MW chav kawm) | 13.8 kV, 18.5 kV |
| 1 lab kilowatt ultra-supercritical unit | 20 kV, 24 kV |
Qhov laj thawj tseem ceeb vim li cas cov tshuab hluav taws xob tsis ncaj qha tso tawm 220V / 380V yog qhov qis -voltage tiam tam sim no siab heev, ua rau coil thiab kab poob rau skyrocket thiab rwb thaiv tsev nqi nce ntau, ua kom ntev - nrug, muaj zog xa mus tsis tau. Yog li ntawd, yuav tsum tau txais ib hom "nruab nrab-voltage, multi-theem transformation" hom.
II. Txoj Kev Taug Kev Hluav Taws Xob: Plaub theem ntawm kev hloov pauv hluav taws xob, Los ntawm lub tshuab hluav taws xob mus rau qhov (socket).
Hluav taws xob mus los ntawm lub tshuab hluav taws xob mus rau cov neeg siv los ntawm plaub theem tseem ceeb: kev txhawb zog thiab kev sib kis, kev txo qis hauv cheeb tsam, kev faib hluav taws xob txo, thiab txo qhov hluav taws xob hauv lub davhlau ya nyob twg. Tag nrho cov txheej txheem cia siab rau transformers rau kev hloov hluav taws xob, thaum kawg sib piv cov khoom siv hluav taws xob hauv tsev thiab kev lag luam.
Kauj Ruam 1: Voltage Boosting thiab Transmission - Los ntawm "Nruab Nrab Voltage" mus rau "Ultra-High Voltage/Extra-High Voltage"
Tom qab lub tshuab hluav taws xob tsim hluav taws xob 6.3kV–24kV nruab nrab- hluav taws xob hluav taws xob, nws tau txuas tam sim ntawd mus rau lub ntsiab kauj ruam- nce transformer, uas nce qhov voltage mus rau 220kV, 500kV, thiab rau inter- kis tau tus mob hauv cheeb tsam, txawm mus rau 1000kV AC thiab ± 800kV voltage.
Kauj ruam 2: Kev txo qis hauv cheeb tsam - Los ntawm "Ultra-High Voltage" mus rau "High Voltage"
Ultra- hluav taws xob hluav taws xob siab tau xa mus rau cov chaw tseem ceeb nyob ib puag ncig lub nroog, qhov chaw uas nws tau nqis mus rau 110kV thiab 35kV high voltage theem los ntawm kauj ruam-down transformers, nkag mus rau hauv nroog cheeb tsam faib network los npaj rau siab -voltage power supply rau hauv nroog thiab chaw ua si.
Kauj Ruam 3: Voltage Kauj Ruam -Kawm - Los ntawm "High Voltage" mus rau "Voltage nruab nrab"
High-voltage hluav taws xob nkag mus rau hauv nroog faib chaw nres tsheb, qhov twg nws tau nqis rov qab mus rau 10kV nruab nrab voltage. Qhov hluav taws xob tam sim no raug xa mus los ntawm cov kab hluav taws xob hauv av lossis cov kab hluav taws xob mus rau cov khoom siv hluav taws xob xa mus nyob ze cov chaw nyob, cov chaw tsim khoom, thiab cov cheeb tsam kev lag luam. Qhov no yog qhov feem ntau voltage theem nyob rau hauv nroog fais fab faib tes hauj lwm.
Kauj Ruam 4: Terminal Voltage Kauj Ruam-Txuas - Los ntawm "Nruab nrab Voltage" mus rau "Low Voltage (Residential/Industrial)"
Qhov no yog cov kauj ruam tseem ceeb ze tshaj rau tus neeg siv. Lub 10kV nruab nrab- hluav taws xob hluav taws xob hloov mus rau 380/220V peb-theem plaub-hlau qis-voltage hluav taws xob los ntawm kev faib hluav taws xob hauv cov chaw nyob thiab cov chaw tsim khoom.
Nws siv peb theem xov hlau thiab ib lub xov hlau nruab nrab los muab peb -theem 380V fais fab rau cov chaw tsim khoom, cov khw muag khoom, thiab cov khoom siv loj, thiab yog sib xws nrog siab - cov khoom siv fais fab xws li lub cev muaj zog, cov cuab yeej siv tshuab, thiab cov cua txias hauv nruab nrab.
III. Kev Tshawb Fawb Tseem Ceeb Tshaj Plaws: Kev Sib Raug Zoo Ntawm 220V thiab 380V
Tsev neeg 220V thiab industrial 380V tsis yog ob lub tshuab hluav taws xob ywj pheej, tab sis yog ob daim ntawv tso tawm ntawm tib yam peb -theem plaub-hlau fais fab mov: Hauv peb-theem hluav taws xob, qhov hluav taws xob ntawm theem kab yog 380V (kab hluav taws xob), thiab qhov hluav taws xob ntawm ib theem kab thiab cov kab nruab nrab yog 220V). Ob leeg txaus siab rau kev sib raug zoo lej ntawm "√3".
Los ntawm ntau txhiab volts ntawm nruab nrab- hluav taws xob hluav taws xob los ntawm cov tshuab hluav taws xob mus rau 220V / 380V qis- hluav taws xob hluav taws xob tom qab ntau qhov kev hloov pauv, txhua kauj ruam ntawm kev hloov hluav taws xob ua raws li cov qauv kev tshawb fawb thiab cov qauv hauv tebchaws. Qhov no ua kom muaj txiaj ntsig ntev - kis tau tus mob nyob deb thiab ua tau raws li qhov xav tau ntawm lub zog muaj kev nyab xeeb ntawm cov xwm txheej sib txawv, uas yog qhov kev txawj ntse ntawm cov tshuab hluav taws xob niaj hnub no.
