1. Kev ua tsis tiav thiab ua rau muaj hluav taws xob hloov hluav taws xob
Kev soj ntsuam txheeb cais qhia tau hais tias qhov txhaum ntawm high-voltage switchgear feem ntau poob rau hauv pawg hauv qab no:
1. Kev tsis kam ua haujlwm thiab ua haujlwm tsis zoo: Hom kev tsis ua haujlwm no yog qhov tsis ua haujlwm tseem ceeb ntawm high-voltage switchgear. Nws cov laj thawj tuaj yeem muab faib ua ob pawg: ib qho yog tshwm sim los ntawm kev ua haujlwm tsis ua haujlwm ntawm lub tshuab ua haujlwm thiab kev sib kis; lwm yam yog tshwm sim los ntawm hluav taws xob tsis ua hauj lwm. Ua los ntawm kev tswj thiab pab lub voj voog.
2. Kev tawg thiab kaw qhov yuam kev: Hom kev ua txhaum no yog tshwm sim los ntawm lub cev hluav taws xob Circuit Court breaker. Rau cov hluav taws xob hluav taws xob uas muaj roj tsawg, qhov tshwm sim tseem ceeb yog roj txhaj tshuaj luv luv, arc extinguishing chamber hlawv, tsis muaj peev xwm tawg, thiab tawg thaum kaw. tos. Rau lub tshuab nqus tsev vacuum breakers, cov tsos mob muaj xws li cov pa tawm hauv lub arc extinguishing chamber thiab lub tshuab nqus tsev vacuum, txo lub nqus tsev vacuum, re-ignition ntawm lub txiav capacitor bank, rupture ntawm lub ceramic raj, thiab lwm yam.
3. Rwb thaiv tsev txhaum: manifested sab nraud rwb thaiv tsev rau hauv av flashover breakdown, internal rwb thaiv tsev rau hauv av flashover breakdown, interphase rwb thaiv tsev flashover breakdown, xob laim overvoltage flashover breakdown, porcelain fwj bushing, capacitor bushing flashover, pollution flashover, tawg, tawg, nqa qws flashover, CT flashover, tawg, tawg, porcelain lub raj mis tawg, thiab lwm yam.
4. Kev ua txhaum tam sim no: Qhov tseem ceeb ntawm kev ua txhaum tam sim no ntawm 7.2 mus rau 12 kV voltage theem yog qhov tsis zoo ntawm qhov kev sib txuas ntawm lub qhov hluav taws xob hloov hluav taws xob, uas ua rau muaj kev sib cuag.
5. Sab nraud quab yuam thiab lwm yam tsis ua haujlwm: suav nrog cov khoom txawv teb chaws cuam tshuam, kev puas tsuaj ntuj tsim, cov tsiaj me luv luv, thiab lwm yam.
2. Kev soj ntsuam thiab kuaj cov qauv ntawm high-voltage switchgear
Raws li ntau hom kev txhaum ntawm high-voltage switchgear, muaj ntau txoj kev kuaj xyuas qhov txhaum:
1. Kev tshawb pom online ntawm cov yam ntxwv ntawm cov tshuab. Cov ntsiab lus saib xyuas muaj xws li: kaw thiab qhib coil circuits, kaw thiab qhib coil tam sim no thiab voltages, Circuit Court breaker txav kev sib cuag stroke, circuit breaker contact speed, kaw lub caij nplooj ntoos hlav, thiab Circuit Court breaker txiav txim. Mechanical vibration thaum lub sij hawm tus txheej txheem, kev txheeb cais ntawm tus naj npawb ntawm Circuit Court breaker ua hauj lwm, thiab lwm yam. Tam sim no, cov neeg kho tshuab raws li txoj cai kev soj ntsuam ntawm Circuit Court breakers mas muaj xws li kev soj ntsuam ntawm stroke thiab ceev, kev soj ntsuam ntawm vibration signals thaum lub sij hawm ua hauj lwm, thiab lwm yam. Kev saib xyuas thaum lub sijhawm ua haujlwm hauv Circuit Court breaker yog nyob ntawm qhov kev hloov pauv ntawm lub sijhawm tshwm sim thiab tus nqi siab tshaj plaws ntawm txhua qhov kev vibration teeb liab, ua ke nrog cov nthwv dej tam sim no ntawm qhov qhib thiab kaw coils, txhawm rau txiav txim siab qhov xwm txheej ntawm lub Circuit Court breaker. Rau lub Circuit Court breaker nrog cov khoom ruaj khov, lub ncov qhov ntau thiab tsawg ntawm nws qhov qhib thiab kaw kev vibration waveforms thiab lub sijhawm sib txawv ntawm txhua lub ncov yog qhov ruaj khov. Lub hauv paus rau kev txiav txim siab seb lub teeb liab vibration tau hloov pauv yog ua ntau qhov kev qhib thiab kaw rau ntawm lub tshuab hluav taws xob tshiab lossis lub Circuit Court breaker tom qab kho dua, thiab sau cov ntawv ruaj khov vibration waveform, uas yuav siv los ua tus yam ntxwv waveform "fingerprint" Circuit Court breaker thiab yuav ntsuas yav tom ntej. Lub vibration waveform yog muab piv nrog "tus ntiv tes" los txiav txim seb tus neeg kho tshuab yam ntxwv ntawm lub Circuit Court breaker yog qhov qub. Raws li radial hauv paus kev ua haujlwm network txoj kev xav (RBF network), qhov seem tsim los ntawm qhov sib txawv ntawm qhov kev noj qab haus huv kev co teeb liab thiab qhov tseeb kev co teeb liab ncov siab tshaj plaws ntawm lub Circuit Court breaker thiab lub sij hawm ntawm qhov cuam tshuam kev tshwm sim yog siv raws li cov yam ntxwv tsis rau Circuit Court breaker. Fault Diagnosis los txiav txim lub Circuit Court breaker. Seb puas muaj qhov txhaum thiab hom kev txhaum. Raws li lub teeb liab singularity nrhiav pom txoj kev xav ntawm wavelet transform, lub teeb liab vibration thaum lub Circuit Court breaker raug kaw yog thawj zaug rau wavelet denoising ua kom huv si lub teeb liab muaj txiaj ntsig. Tom qab ntawd lub Hilbert transform yog siv los rho tawm lub teeb liab lub hnab ntawv, thiab lub wavelet transform yog ua rau ntawm lub hnab ntawv kom tau txais cov teeb liab waveforms ntawm txhua qhov ntsuas. Thaum kawg, qhov singularity Performance index ntawm lub teeb liab lub hnab ntawv ncov yog xam raws li qhov transitivity ntawm lub modulus siab tshaj plaws ntawm txhua qhov ntsuas ntawm lub wavelet transform, thiab yog siv los ua tus yam ntxwv parameter rau Circuit Court breaker txhaum kuaj. Nws yog ib txoj kev tshiab thiab muaj txiaj ntsig zoo.
Stroke-time tus yam ntxwv saib xyuas yog hais txog kev hloov pauv hloov pauv hloov pauv mus rau hauv cov khoom siv hluav taws xob mem tes los ntawm photoelectric sensor. Los ntawm kev sau cov naj npawb ntawm cov pulses, tag nrho cov kab mob stroke tsis tuaj yeem ntsuas tau; nyob rau tib lub sijhawm, los ntawm kev kaw lub sijhawm thaum txhua qhov hluav taws xob mem tes tsim tawm, qhov siab tshaj plaws thiab qhov nruab nrab ceev thaum lub sij hawm txav ntawm qhov kev sib cuag tuaj yeem raug xam. Yog li ntawd, ntsuas qhov qhib thiab kaw cov yam ntxwv ntawm lub ntsiab ncej txuas txuas txuas ntawm lub Circuit Court breaker tuaj yeem cuam tshuam cov yam ntxwv ntawm cov neeg sib txuas. Kev soj ntsuam cov load tam sim no thiab tus naj npawb ntawm cov pib ntawm lub zog cia lub cev muaj zog tuaj yeem cuam tshuam txog kev ua haujlwm ntawm lub load (hydraulic operating mechanism), thiab tseem tuaj yeem txiav txim siab seb lub cev muaj zog li cas thiab muaj kev cuam tshuam cov lus zais ntawm kev ua haujlwm hydraulic.
2. Kev soj ntsuam hauv online ntawm kev ua haujlwm hluav taws xob suav nrog kev saib xyuas ntawm Circuit Court breaker breaker tam sim no weighted tus nqi, arc extinguishing chamber nqus degree, thiab lwm yam. Siv sib npaug hnav curves nyob rau hauv sib txawv tawg tam sim no, cov txheeb ze hluav taws xob coj mus rau txhua qhov tam sim no tawg yog accumulated. Tag nrho cov khoom siv hluav taws xob tso cai ntawm txhua qhov hluav taws xob hluav taws xob yog txiav txim siab los ntawm nws qhov ntsuas luv luv-circuit breaking tam sim no thiab cov sij hawm tso cai rau tawg ntawm tag nrho lub peev xwm. Rau calibration, cov khoom siv coj los siv tau los ua lub hauv paus rau kev txiav txim siab nws lub neej hluav taws xob. Daim ntawv no nthuav tawm cov xwm txheej uas cuam tshuam rau lub neej ntawm kev sib cuag ntawm lub tshuab nqus tsev hluav taws xob thiab qee qhov SF6 Circuit Court breakers, thiab qhia txog kev txhim kho hauv online rau kev siv hluav taws xob lub neej ntawm lub tshuab nqus tsev Circuit Court breakers. Txoj kev no yuav siv sij hawm mus rau hauv tus account lub sij hawm rhuav tshem thiab arcing lub sij hawm ntawm txhua theem, thiab yog qhov tseeb Qhov kev ua tau zoo tau zoo dua qub thiab tuaj yeem cuam tshuam cov hluav taws xob hnav ntawm txhua theem.
