1. Kev taw qhia txog kev ua tiav ntawm cov khoom siv rau zaus hloov dua siab tshiab series resonance test.
Covsib txawv zaus series resonancexeem siv cov inductance ntawm lub reactor thiab lub capacitance ntawm cov khoom kuaj kom ua tiav capacitance resonance thiab tau txais high voltage thiab siab tam sim no. Nws yog ib txoj hauv kev tshiab thiab cov qauv hauv kev ntsuas siab tam sim no -voltage test, uas tau siv dav hauv tsev thiab txawv teb chaws. Series resonance yog ib tug resonant tam sim no filtering Circuit Court uas yuav txhim khu lub distortion ntawm lub hwj chim waveform, tau zoo dua sine voltage waveform, thiab zoo tiv thaiv kev sib haum xeeb ncov ntawm cov khoom kuaj; Thaum lub rwb thaiv tsev ntawm cov khoom kuaj yog punctured, tam sim no tam sim no detuned, thiab lub voj tam sim no poob sai sai rau ib feem kaum ntawm qhov ntsuas tam sim no; Thaum flashover breakdown tshwm sim, vim qhov poob ntawm resonance tej yam kev mob, lub arc tuaj yeem tua. Ntxiv rau qhov txo qis tam sim no ntawm luv luv - Circuit Court tam sim no, qhov hluav taws xob siab kuj ploj tam sim ntawd, thiab nws yuav siv sij hawm ntev dua los kho qhov hluav taws xob. Nws yog ib qho yooj yim los txiav tawm lub hwj chim dua nyob rau hauv flashover voltage. Yog li, nws yog qhov tsim nyog rau kev ntsuas hluav taws xob tiv thaiv hluav taws xob ntawm high-voltage thiab siab- cov khoom siv fais fab.
2. Daim ntawv thov ua tiav ntawm zaus conversion series resonance test khoom hauv GLS system
Qhov ntawm -qhov chaw voltage tiv thaiv qhov ntsuas ntawm GIS yog ua los ntawm AC voltage, oscillating xob laim impulse voltage, oscillating ua hauj lwm mem tes voltage, thiab lwm yam. AC voltage withstand test yog ib tug nquag siv txoj kev nyob rau hauv lub - qhov chaw voltage withstand test ntawm GIS, uas muaj peev xwm zoo xyuas txawv txawv hluav taws xob teb qauv (xws li electrode puas). Tam sim no, vim muaj kev txwv hauv cov cuab yeej ntsuas thiab cov xwm txheej, tsuas yog ntawm - qhov chaw ntsuas qhov hluav taws xob tau ua. Txawm li cas los xij, feem ntau GIS systems uas tsis tau ua tiav ntawm - qhov chaw AC voltage tiv thaiv kev sim tau ntsib teeb meem. Yog li ntawd, nws yog ib qho tsim nyog yuav tau ua ntawm - qhov chaw voltage tiv thaiv kev sim ntawm GIS systems. Tam sim no, vim muaj kev txwv hauv cov cuab yeej ntsuas thiab cov xwm txheej, tsuas yog nyob rau ntawm - qhov chaw ntsuas qhov hluav taws xob yog ua
(1) Cov kev cai xeem
① GlS yuav tsum tau nruab tag nrho. SF6 roj yuav tsum tau sau rau hauv qhov ntsuas qhov ntom ntom, thiab ntsuas qhov ntsuas ntawm lub hauv paus tseem ceeb, kev ntsuam xyuas ntawm ntau yam khoom, thiab nrhiav pom cov ntsiab lus ntawm SF6 roj dej thiab cov dej xau tau tiav. Tag nrho cov theem nrab windings ntawm tam sim no transformers tau grounded, thiab theem nrab voltage windings ntawm voltage transformers tau raug txiav thiab grounded. ② Ua ntej ua AC tiv thaiv qhov ntsuas hluav taws xob, cov khoom siv hauv qab no yuav tsum raug cais tawm ntawm GlS siab- cov xov hlau hluav taws xob thiab cov busbars. ③ Txhua qhov tshiab tau teeb tsa ntawm GIS yuav tsum tau kuaj xyuas qhov rwb thaiv tsev. Thaum kuaj xyuas qhov txuas ntxiv, cov khoom qub ntawm cov khoom siv uas nyob ib sab yuav tsum raug txiav tawm thiab hauv av.
(2) Txoj kev siv qhov ntsuas hluav taws xob
Siv qhov ntsuas hluav taws xob mus rau ntu nruab nrab ntawm tus neeg xyuas pib thiab lub casing; Rau lwm yam tsis xeem theem thiab lub plhaub hauv av sib txuas, thov siv hluav taws xob los ntawm bushing. Thaum lub sij hawm xeem, siv qhov voltage rau txhua yam ntawm GlS yam tsawg ib zaug. Nyob rau tib lub sijhawm, kom tsis txhob muaj kev puas tsuaj ntawm cov khoom qub, qhov ntsuas hluav taws xob yuav tsum tau siv rau ntau yam. Feem ntau, tsuas yog ua cov theem rau hauv av AC tiv thaiv qhov ntsuas hluav taws xob ntawm qhov chaw. Yog hais tias qhov kev sib cais ntawm lub Circuit Court breaker puas los yog disassembled thaum lub sij hawm thauj mus los thiab installation, nws yog tsim nyog los ua AC dielectric xeem ntawm qhov chaw nres nkoj. Tus nqi hluav taws xob tiv taus yuav tsum ua raws li theem rau hauv av AC tiv taus tus nqi hluav taws xob. Yog tias tag nrho cov capacitance ntawm GlS loj, qhov ntsuas qhov ntsuas hluav taws xob tuaj yeem ua rau hauv ntu.
3. AC dielectric test program
Thawj theem ntawm AC dielectric xeem hauv GIS yog "kev ua kom huv si nyuaj", txhawm rau tshem tawm cov khoom siv hluav taws xob lossis tsis yog -cov khoom siv hluav taws xob uas yuav muaj nyob hauv GIS. Cov khoom no tuaj yeem raug coj los rau hauv lub sijhawm teeb tsa, lossis tsim cov khib nyiab hlau tom qab ntau qhov kev ua haujlwm, los yog daim ntawv fastener txiav cov khib nyiab thiab electrode nto burrs. "Precision purification" tuaj yeem txav cov khoom siv hluav taws xob mus rau thaj chaw hluav taws xob tsawg lossis ntes cov khoom, thiab hlawv cov burrs ntawm qhov chaw electrode yam tsis muaj kev puas tsuaj rau lub rwb thaiv tsev. Tus nqi hluav taws xob "empirical purification" yuav tsum qis dua qhov nqi hluav taws xob no. Qhov thib ob theem yog dielectric xeem, uas yog ua tom qab "precision purification" txheej txheem. Lub sijhawm yog 1 feeb.
4. Kev txiav txim ntawm qhov ntsuas qhov ntsuas hluav taws xob
Yog tias txhua feem ntawm GIS tau tiv thaiv qhov ntsuas qhov ntsuas hluav taws xob raws li cov txheej txheem kev sim xaiv yam tsis muaj kev cuam tshuam, nws raug txiav txim siab tias tag nrho GIS tau dhau qhov kev xeem; Yog hais tias qhov kev puas tsuaj tshwm sim thaum lub sij hawm kuaj, yuav tsum tau ua raws li qhov kev ntsuas hluav taws xob tiv thaiv hluav taws xob, ntau yam acoustic, kho qhov muag, electrochemical, thiab lwm yam cuam tshuam los ntawm qhov paug tawm, nrog rau cov txiaj ntsig tau muab los ntawm lwm yam kev kuaj xyuas txhaum cai thaum lub sij hawm kuaj. Yog tias tsis muaj teeb meem, cov kauj ruam hauv qab no tuaj yeem ua:
① Siv qhov ntsuas hluav taws xob uas tau teev tseg thiab rov kuaj dua. Yog tias cov khoom siv lossis cov khoom thaiv roj tuaj yeem tiv taus nws, qhov tso tawm yog tus kheej -kho tawm; Yog hais tias qhov rov ua dua qhov ntsuas hluav taws xob nce mus txog tus nqi tas li thiab lub sijhawm teev tseg, cov khoom kuaj pom tau tias tsim nyog, txwv tsis pub cov khoom hauv qab no yuav raug tua. ② Tshem tawm cov khoom siv, qhib qhov sib txawv, ua tib zoo tshuaj xyuas cov txheej txheem rwb thaiv tsev, thiab ua tib zoo ntsuas qhov tsim nyog rov qab ua ntej mus rau qhov ntsuas hluav taws xob tom ntej.
5. Cov txheej txheem rau kev txheeb xyuas qhov yuam kev hauv GIS voltage tiv thaiv kev ntsuas
Yog tias lub sijhawm nruab nrab ntawm cov kab nkag thiab tawm ntawm qhov hluav taws xob tiv thaiv kev ntsuas tom qab GIS segmentation loj dua, thiab tsis yog tus kheej rov qab tawm los yog kev puas tsuaj tshwm sim thaum lub sijhawm kuaj, nws nyuaj rau txiav txim siab qhov tseeb ntawm qhov txhaum ntawm tib neeg lub pob ntseg thiab tsuas yog saib xyuas nws, uas tuaj yeem yooj yim ua rau kev txiav txim siab thiab pov tseg ntawm cov neeg ua haujlwm, cov khoom siv, thiab cov khoom siv tsis tsim nyog; Yog tias qhov chaw ua txhaum cai raug tsim los ntawm lub hauv paus ntsiab lus ntawm lub plhaub vibration los ntawm kev poob siab yoj tawm los ntawm kev tawm, lub sij hawm tawm tuaj yeem txiav txim siab. Ua ntej txhua qhov ntsuas qhov ntsuas hluav taws xob, cov ntsuas hluav taws xob tuaj yeem ntsia tau rau ntawm qhov ntsuas qhov ntsuas, tshwj xeeb tshaj yog nyob rau hauv Circuit Court breaker, kev sib cais hloov, busbar, thiab insulator kev twb kev txuas lub plhaub ntawm txhua qhov kev sib txuas sib txuas.
