Substation commissioning thiab high voltage hipot testing yog inherently txaus ntshai ib puag ncig. Kev khiav hauj lwm qib siab hloov pauv zaus series resonant systems suav nrog kev tuav cov hluav taws xob loj heev uas yuav tsum muaj kev qhuab qhia tsis zoo. Kev saib xyuas ib leeg tuaj yeem ua rau muaj kev puas tsuaj loj rau cov khoom muaj nqis siab -, xws li 10kV / 35kV XLPE fais fab cables lossisnruab nrab-voltage switchgears, los yog cuam tshuam tus neeg teb xov tooj kev nyab xeeb. Ua raws li tsib txoj kev nyab xeeb tseem ceeb no yog qhov yuav tsum tau ua rau txhua tus kws tshaj lij-voltage test engineering team.
Xyaum 1: Validate Automatic Voltage Regulation (AVR) thiab tshaj -Voltage Protection
Ua ntej pib qhov twgAC tiv taus cov khoom siv kuaj, engineers yuav tsum configure thiab ob -xyuas lub built- nyob rau hauv tsis siv neeg parametric tiv thaiv. Qhov dhau-voltage, tshaj-tam sim no, thiab flashover tiv thaiv qhov pib yuav tsum tau teem rau ntawm tib neeg-tshuab interface (HMI). Kev siv lub zog hluav taws xob nrog cov khoom siv hluav taws xob siab tshaj AVR tau lees paub tias txawm tias lub tshuab hluav taws xob lub tshuab hluav taws xob portable muab cov khoom siv hluav taws xob tsis ruaj khov, lub kaw lus yuav lim cov kev sib raug zoo thiab kaw tsis pub dhau microseconds thaum lub sij hawm rwb thaiv tsev tawg, ua rau muaj kev phom sij.
Xyaum 2: Siv nruj nruj ib leeg-Point Common Grounding
Kev siv tsis raug hauv av yog ib qho tseem ceeb ntawm kev ntsuas tsis ua haujlwm thiab kev sib tsoo hauv qhov chaw thaum kuaj kab hluav taws xob. Tag nrho cov khoom siv hauv lub cev-xws li lub excitation transformer, capacitive voltage divider, thiab modular resonant reactors- yuav tsum tau sib txuas ua ke rau ib qho chaw sib koom ua ke hauv av. Floating grounds tuaj yeem ua rau muaj qhov cuam tshuam loj heev rau kev tawm tswv yim rau hauv qis -voltage control systems thaum lub teeb nyem cable, ua rau muaj kev puas tsuaj loj heev.
Xyaum 3: Tswj Cov Cuab Yeej Siv Hluav Taws Xob uas yuav tsum tau ua
Thaum configuring siab -voltage resonant reactors nyob rau hauv series rau elevated test voltages, lub cev clearance yog tseem ceeb heev. High-voltage leads thiab reactor crowns yuav tsum muaj kev nyab xeeb nruj ntawm cov phab ntsa substation, scaffolding, laj kab thaiv, thiab lwm yam hauv av. Kev tshem tawm huab cua tsis txaus ua rau txoj hauv kev ionization, ua rau huab cua ntxov ntxov uas ua rau kev sim siab thiab ua rau cov neeg ua haujlwm muaj kev pheej hmoo.
Xyaum 4: Cais tawm thiab txheeb xyuas qhov Kev Ntsuas Qhov Ciam Teb
Thaum lub sij hawm tu cov khoom siv hluav taws xob niaj hnub lossis kev ua haujlwm tshiab substation, cov cuab yeej hluav taws xob uas nyob ib sab feem ntau tseem muaj zog. Kuaj pab pawg yuav tsum tau ua tib zoo cais cov phiaj cable lossis switchgear thaiv. Tshem tawm tag nrho cov cuab yeej hloov pauv (CTs thiab PTs), hluav taws xob ntes, thiab cov khoom siv hluav taws xob sib txuas los ntawm cov khoom ntsuas. Kev tsis cais cov ciam teb no tuaj yeem ua rau tsis pom kev tuaj yeem ua rau muaj kev puas tsuaj siab -voltage test waves rau hauv cov khoom siv hluav taws xob tsis zoo hauv chav tswj.
Xyaum 5: Teem kom muaj pov thawj pov tseg thiab siv cov pas nrig pom
High -voltage capacitive cuab tam, tshwj xeeb tshaj yog ntev underground XLPE fais fab cables, khaws cia cov hluav taws xob seem uas ploj lawm ntev tom qab lub resonant test set yog powered down. Cov neeg ua haujlwm yuav tsum tsis txhob kov qhov siab -voltage circuit tam sim ntawd tom qab kev sim. Ib qho kev cog lus hauv av thiab tso tawm cov pas nrig yuav tsum tau siv rau lub cev rau cov neeg xyuas kom txog thaum lub sijhawm tiag tiag -timeParametric tso saib ntawm qhov hluav taws xob faib hluav taws xob lees paub qhov tsis muaj peev xwm, ua raws li qhov pom kev nyab xeeb hauv av clamp ua ntej kev hloov kho kev hloov pauv pib.
