Tam sim no hloov pauv yog ib qho tseem ceeb ntawm lub zog hluav taws xob. Lawv cov tub ntxhais muaj nuj nqi yog hloov kho qhov siab tam sim no mus rau qhov ntsuas me me ntawm qhov tam sim no rau kev ntsuas, kev tiv thaiv thiab tswj. Ntawm no yog cov laj thawj tseem ceeb los siv CTS thiab lawv cov ntawv teev npe tshwj xeeb:
1.Qhov kev cais tawm: Ua kom tib neeg thiab khoom siv muaj kev nyab xeeb
Hauv kev xa khoom siab lossis faib cov tshuab, ntsuas ncaj qha ntawm cov kev kub siab tam sim no (piv txwv li ntau txhiab tus neeg ntsuas hluav taws xob, tsim kom muaj kev pheej hmoo ntawm hluav taws xob. Infition tam sim no siv hluav taws xob induction kom hloov siab dua qub rau hauv qis thib ob tam sim no (feem ntau) lossis 1a). Qhov no yuav ua kom cov neeg ua haujlwm ruaj ntseg los ntawm kev ntsuas cov twj paj nruag thiab cov khoom tiv thaiv los ntawm high- voltage circuits.
Khoom Tiv Thaiv Khoom
I.Qhov theem theem siab yog cais los ntawm lub siab voltage kawg kom tiv thaiv cov hluav taws xob tsis zoo (xws li ua rau muaj kev ntsuas ntsuas. Piv txwv li, nyob rau hauv qhov kev tshwm sim ntawm lub luv luv Circuit Court, tsuas yog cov rated tam sim no dhau los ntawm theem nrab Circuit Court, tiv thaiv cov twj paj nruag thiab relay los ntawm kev ua kom muaj peev xwm ua tau. ii. Kev hloov dua tshiab tam sim no: hloov ntsuas ntsuas thiab cov khoom siv tiv thaiv
Kev yoog tau ntawm cov twj paj nruag ntsuas
Ntsuas seev xws li ammeters thiab fais fab metres feem ntau muaj cov me me ranges (piv txwv li}} A) thiab tsis tuaj yeem ntsuas qhov loj me me hauv siab- voltage Systems. Cov hloov hluav taws xob tam sim no txo qhov tam sim no los ntawm ib qho tam sim no (piv txwv li, 500: 5), cia cov ntsuas ntsuas kom nyab xeeb thiab muaj txiaj ntsig.
Ii.Sensitivity ntawm Cov Khoom Siv Tiv Thaiv
Relay Kev Tiv Thaiv Cov Khoom Siv (piv txwv li kev tiv thaiv thiab kev tiv thaiv kev sib txawv) yuav tsum muaj sai sai rau kev hloov pauv tam sim no. Lub chaw hloov hluav taws xob tam sim no tuaj yeem muab cov teeb liab raug kom ntseeg tau tias cov cuab yeej tiv thaiv khiav hauv lub sijhawm thaum lub sijhawm ua tsis taus lossis tiv thaiv cov khoom siv los ntawm kev puas tsuaj lossis nce ntxiv. Piv txwv li, hauv Transformer tiv thaiv, hloov pauv tam sim no tuaj yeem tshawb pom qhov sib txawv me me tam sim no thiab paub kev tiv thaiv ntau yam.
III. Cov Qauv Qauv thiab Kev Lag Luam: Txo cov nqi system
Kev sib raug zoo ntawm cov qauv tsev kawm theem nrab
Qhov thib ob tam sim no ntawm kev hloov pauv tam sim no feem ntau yog qauv rau ib qho ntawm cov twj siv sib txawv thiab cov khoom siv tiv thaiv ntawm cov qauv sib txawv thiab cov qauv tsim qauv. Piv txwv li, tib lub transformer tib tam sim no tuaj yeem txuas nrog ammeter, fais fab meter, thiab cov relay tiv thaiv. Txo ntu kev sib tw ntim ntawm cov neeg saib xyuas
Vim tias cov theem qub tam sim no yog qhov tsis tshua muaj, ib lub nyias nyias nyias tuaj yeem siv rau kev kis teeb liab, uas txo cov nqi thiab nyuaj rau cov khoom siv. For example, the conductor of carrier 5A has a much smaller cross-section volume than the conductor of carrier 500A.
IV. Taw qhia Ntau - Circuit Court Kev Ntsuam Xyuas: Yooj Yim Qauv Qauv
Tib transformer soj ntsuam ntau lub voj voog
Hauv ib peb {- theem txheej txheem, txhua theem tam sim no siv tau siv cov hloov pauv tshwj xeeb, lossis cov hloov pauv tau tshwj xeeb siv ntau yam hloov tshiab. Piv txwv li, xoom -} ntu tam sim no transformer Tam sim no tuaj yeem kuaj tau peb tam sim no tsis txaus ntseeg thiab paub qhov tsis yooj yim kev tiv thaiv.
Kev Tiv Thaiv Nruab Nrab thiab Kev Ntsuas
Hloov pauv tam sim no hloov cov phiajcim tam sim no ntawm txhua lub voj voos mus rau chav tswj hwm rau hauv paus tswj hwm thiab kev tswj hwm. Piv txwv li, nyob rau hauv ib qho hloov, tam sim no hloov pauv cov teeb liab tam sim no los ntawm txhua qhov hluav taws xob rau kev sib txuas lus cav rau kev saib xyuas cov chaw taws teeb thiab tswj.
V. TSHWJ XEEB APPLICES
Zog Metering
Hauv cov metres meters, hloov pauv tau tuaj yeem hloov loj tam sim no ntawm tus neeg siv khoom me me, tso cai rau lub ntsuas ntsuas kom ntsuas cov kev siv fais fab. Piv txwv li, tsev neeg meters siv cov hloov pauv tam sim no los ntsuas cov khoom xa tuaj tam sim no thiab suav cov nqi hluav taws xob tam sim no. Kev Ntsuam Xyuas Harmaul
High - precision Tam sim no hloov tuaj yeem kuaj cov harmonic Cheebtsam hauv qhov tam sim no thiab siv lawv rau kev tsom xam lub zog. Piv txwv li, hauv kev thov nrog cov khoom siv tsis loj, xws li inverters, hloov pauv tuaj yeem pab ntsuas qhov kev sib kis tau zoo.
Txuas Ntxiv Hluav Taws Xob
Hauv kev siv hluav taws xob txuas ntxiv xws li photovoltaic (PV) thiab cov hloov cua, tam sim no cov hloov pauv tuaj yeem ua kom muaj raws li cov qauv GROc. Piv txwv li, hloov pauv tam sim no ntawm cov zis ntawm cov invere tau tuaj yeem tshawb pom cov nthwv dej tam sim no txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau sib kab.
VI. Taw qhia Tiag - Ntiaj Teb Piv Txwv
Kev tiv thaiv
Hauv 220kV hloov, hloov pauv hloov tam sim no (piv txwv li} A) rau theem ob (piv txwv li} A) rau kev tiv thaiv zoo. Thaum tus neeg hloov pauv sab hauv, cov cuab yeej tiv thaiv sib txawv sai sai ua txhaum kev txhaum los ntawm kev sib piv cov cim ntawm cov hloov pauv tam sim no ntawm ob sab.
Kev tiv thaiv muaj zog
Nyob rau hauv kev loj lub cev muaj zog circuits Circuit Court, hloov pauv tam sim no tuaj yeem soj ntsuam qhov tam sim no ntawm lub cev muaj zog. Thaum muaj ntau dhau ntawm CirciCet tshwm sim, lub teeb tsa kev tiv thaiv siv hluav taws xob hloov pauv hloov chaw kom txiav lub zog hluav taws xob thiab tiv thaiv lub cev muaj zog. Kev nyab xeeb hluav taws xob hauv tsev
Hauv cov neeg muaj tswv yim hluav taws xob muaj zog, hloov pauv tam sim no tuaj yeem kuaj pom so kua muag. Thaum lub toast tam sim no tshaj 30MA, lub Circuit Coffer breaker tam sim ntawd jumps kom tsis txhob muaj hluav taws xob.
