Cov txheej txheem txheej txheem thiab kev ceev faj rau Impact Voltage Test

Txhua yam kev ua ub no muaj feem xyuam rau qhov kev ntsuas hluav taws xob impulse yuav tsum nruj me ntsis ua raws li cov qauv thoob ntiaj teb thiab lub teb chaws kom paub meej cov qauv kev sib piv, kev sib piv thiab kev tsis ncaj ncees ntawm qhov kev xeem.
Basic General Standards (Test Methods and Measurement Criteria)
IEC 60060-1 / GB/T 16927.1: "High Voltage Test Technology - Ntu 1: Cov ntsiab lus dav dav thiab cov kev xav tau xeem". Qhov no yog qhov tseem ceeb tshaj plaws thiab cov txheej txheem dav dav, qhia meej meej cov qauv waveforms xws li xob laim impulse thiab kev ua haujlwm impulse, cov txheej txheem kuaj, nrog rau kev tso cai sib txawv rau waveform tsis (piv txwv li, qhov sib txawv ntawm cov qauv xob laim: pem hauv ntej ± 30%, ib nrab hnub ncov ± 20%).
IEC 60060-2 / GB/T 16927.2: "High Voltage Test Technology - Ntu 2: Kev Ntsuas Qhov Ntsuas". Cov qauv no tshwj xeeb thiab nthuav dav qhia txog cov kev xav tau ntawm kev ua haujlwm, cov txheej txheem calibration thiab kev ntsuas tsis paub meej rau kev ntsuas ntsuas xws li voltage dividers thiab digital recorders.
2. Cov qauv ntsuas cov khoom tshwj xeeb
Cov qauv no, nyob rau hauv lub moj khaum ntawm cov qauv hauv paus, qhia txog cov kev xeem tshwj xeeb rau cov khoom siv tshwj xeeb.
Fais fab Transformer: IEC 60076-3 / GB / T 1094.3 qhia txog cov txheej txheem tshwj xeeb, kev xeem sib lawv liag (xws li nthwv dej ua ntej, tom qab ntawd txiav nthwv dej, thiab tom qab ntawd tag nrho nthwv dej dua) thiab txoj kev txiav txim txhaum cai (tsuas yog siv "waveform piv txoj kev") rau kev ntsuas qhov cuam tshuam ntawm transformer.
High-voltage switchgear: Cov kev cai rau kev ntsuam xyuas kev rwb thaiv tsev rau siab -voltage switchgear tau teev nyob rau hauv IEC 62271-1 / GB / T 11022.
Rwb thaiv tsev: IEC 60815 / GB / T 26218 series cov qauv npog cov kev ntsuas cuam tshuam rau cov rwb thaiv tsev nyob hauv qhov chaw muaj kuab paug.
Cov txheej txheem tseem ceeb ntawm kev xeem: Ua ntej txhua qhov kev xeem, qhov ntsuas ntsuas yuav tsum tau ua kom tsis muaj qhov ntsuas qhov ntsuas waveform; Thaum lub sij hawm qhov kev xeem, los ntawm kev sib piv seb qhov siv voltage waveform thiab nruab nrab point tam sim no (los yog kis tau tus mob voltage) waveform ntawm cov qauv xeem muaj distortion, lub rwb thaiv tsev sab hauv tuaj yeem txiav txim siab tias tau tawg lawm.
Impulse voltage generator
Kev ceev faj rau qhov cuam tshuam qhov ntsuas qhov chaw
Tswj ntawm qhov chaw sim
Qhov chaw sim yuav tsum raug cais tawm ntawm lub cev los ntawm kev ruaj ntseg laj kab, thiab cov cim ceeb toom nyeem "High Voltage Hazard, Tsis Muaj Kev Nkag Nkag" yuav tsum tau dai ntawm qhov nkag.
Thaum lub sij hawm xeem, ib tug txheej txheem clearance tau siv. Tsuas yog tom qab tus thawj saib xyuas kev ntsuam xyuas tau lees paub tias txhua tus neeg ua haujlwm tsis yog -cov neeg ua haujlwm kuaj tau khiav tawm mus rau thaj chaw nyab xeeb thiab lub suab thiab lub teeb ceeb toom tau qhib, tuaj yeem hais kom lub siab nce ntxiv.
Grounding thiab Discharge Specifications
Tag nrho cov khoom siv kuaj (qhov cuam tshuam lub tshuab hluav taws xob lub cev, qhov hluav taws xob faib hluav taws xob, thiab qhov hloov hauv av) nrog rau lub plhaub sab nraud ntawm cov qauv ntsuas yuav tsum tau txuas nrog kev ywj pheej thiab qis -impedance siab rau hauv av.
Yuav tsum tau tshem tawm cov txheej txheem: Ua ntej yuav hloov cov xaim, kov cov qauv kuaj lossis ua cov khoom siv tu, lub hauv paus ntsiab lus ntawm "tso tawm ua ntej, tom qab ntawd ua haujlwm" yuav tsum ua raws. Cov neeg ua haujlwm yuav tsum siv cov pas nrig hauv av uas muaj cov txheej txheem rwb thaiv tsev sib haum nrog cov cuab yeej siv, thiab tso tawm qhov siab -voltage kawg, txhua qib ntawm lub zog cia capacitor, thiab siab -voltage terminals ntawm cov qauv ntsuas mus rau hauv av nyob rau hauv ib ntus, kom ntseeg tau tias muaj kev tawm thiab luv luv. Cov txheej txheem no yuav tsum tau ua raws li tus txheej txheem kev ua haujlwm yuav tsum tau ua thiab tsis tuaj yeem ua kom yooj yim.
Kev Tiv Thaiv Hluav Taws Xob thiab Kev Npaj Thaum Muaj Xwm Ceev
Qhov chaw sim yuav tsum tau nruab nrog hluav taws kub - cov khoom siv sib ntaus sib tua tsim nyog rau hluav taws xob hluav taws xob (xws li cov tshuab tua hluav taws carbon dioxide).
Rau cov roj-cov qauv ntsuas rau hauv dej, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas lub siab tso tawm cov cuab yeej thiab lub tshuab ua pa ua ntej, thiab saib xyuas seb puas muaj cov pa phem tawm thaum lub sijhawm kuaj.
Kev npaj thiab ua pov thawj ua ntej qhov kev sim
Cov khoom siv kuaj xyuas
Tshawb xyuas seb qhov sib txawv ntawm txhua theem ntawm lub tshuab hluav taws xob cuam tshuam puas yog raws li cov nqi preset. Qhov saum npoo ntawm cov txheej txheem rwb thaiv tsev yuav tsum huv, qhuav thiab tsis muaj kev puas tsuaj.
Tshawb xyuas tag nrho cov siab -voltage kev twb kev txuas conductors thiab shrouds, kom ntseeg tau tias kev sib txuas txhim khu kev qha thiab du nto kom tshem tawm qhov cuam tshuam ntawm corona tawm ntawm qhov ntsuas.
Paub meej tias qhov ntsuas cable ntawm qhov qis- qhov hluav taws xob sab ntawm qhov hluav taws xob faib hluav taws xob yog ob npaug - txheej tiv thaiv thiab muaj qhov zoo tib yam - taw tes hauv av kom tsis txhob cuam tshuam los ntawm cov voj voog hauv av.
Standardization ntawm ib puag ncig tej yam kev mob
Ua ntej qhov kev xeem raug cai, ib puag ncig qhov kub thiab txias, txheeb ze humidity thiab atmospheric siab yuav tsum tau sau tseg. Thiab raws li IEC 60060-1 / GB / T 16927.1 tus qauv, qhov ntsuas qhov ntsuas hluav taws xob yuav tsum raug kho raws li tus qauv huab cua.
