Inkqubo yokuJonga kwi-Intanethi ye-Metal oxide Arrester
Ngokuqhelekileyo kukho iindlela ezimbini zokubeka iliso kwimeko yokufakelwa kwezixhobo zombane eziphezulu kwizikhululo ezincinci: ukubeka iliso kwi-intanethi kunye nokuphila (okuphathekayo) kwi-intanethi.Owangaphambili unokufumana iiparitha zeempawu ezibonisa ukugquma okungaqhelekanga kwesixhobo nangaliphi na ixesha, elilungele ulawulo oluzenzekelayo.Nangona kunjalo, utyalo-mali lukhulu ngokwentelekiso, ukufakela kunye nokwakhiwa kuyingxaki noko, kwaye ukulungiswa rhoqo kuyafuneka.Okokugqibela, ineenzuzo zotyalo-mali oluphantsi, ekujoliswe kuyo kakhulu, kulula ukuyifaka, ukuyigcina nokuhlaziya.Logama nje iyunithi yesampulu ifakwe kwisixhobo sombane kwangaphambili, ukubonwa rhoqo kunokwenziwa kwisixhobo sombane esisebenzayo, kwaye isiphene sokugquma singafumaneka kwangethuba, ukuze kwandiswe ixesha lokuvavanywa kokungaphumeleli kombane kunye nokutshintsha ngokupheleleyo. -line esweni indlela.
I-GDDJ-HVC i-dielectric loss tester ye-live capacitive isixhobo ingasetyenziselwa ukulinganisa ilahleko ye-dielectric kunye ne-capacitance yezixhobo ze-capacitive (i-bushing, i-CT, i-CVT, i-coupling capacitor), kunye nokufumanisa iimpazamo ze-insulation ngempumelelo.
1. Inzwa yangoku yomngxuma yangaphandle ngokuchaneka okuphezulu idla ngokusetyenziswa endaweni yeyunithi yesampulu yemveli, ebandakanya ngaphezulu kwesekethe enye yokutshintsha.Ngexesha lovavanyo, iithebhu ezininzi ezimfutshane ziyafuneka ukukhokela ukhuseleko lwangoku kwisixhobo sokuvavanya.I-GDDJ - i-HVC isebenzisa i-traditional straight-through structure, inokufakwa kufuphi nezixhobo, i-lead of end shielding ayiphulwanga kwaye ubude bufutshane kakhulu, ezithintela isiphaluka esivulekileyo sokukhusela ekupheleni.Inzwa iyakwazi ukubona ngokuchanekileyo iimpawu ngaphakathi kwe-100μA ~ 700mA.I-impedance ye-sensor iphantsi, inokumelana nombane we-frequency yangoku i-10A kunye ne-10kA yempembelelo yombane yangoku, ukuhlangabezana neemeko zokusebenzisa ukufunyanwa kwe-intanethi.
2. Iyunithi yesampulu ithatha igobolondo le-aluminium e-die-casting yokutywinwa koyilo olungangeni manzi, kwaye yamkele isinxibelelanisi sekhebula elingangeni manzi kwimveliso yesibini, elungele ukuqhagamshelwa;Emva kokuba i-sensor ifakiwe, ayidli amandla.Ukuvavanya, kuphela intambo yesibini yeyunithi yesampula kufuneka idibaniswe, kwaye "iplagi kunye nokudlala" inokufezekiswa ngaphandle kokusebenza kwintambo yesiginali yokukhusela.
3. Iprosesa engundoqo yesixhobo yi-American TI 32-bit floating-point high performance digital signal processor (DSP), eqhuba inkqubo yokusebenza yexesha langempela kwaye ithathe i-16-bit, isantya esiphezulu, i-synchronous multi-channel. isampula ye-analog converter yedijithali (A/D) ukuqonda umlinganiselo wexesha langempela kunye nokubalwa okuchanekileyo okuphezulu kobungakanani obubekwe esweni.Iyakwazi ukujonga izixhobo ezininzi ngaxeshanye.
4. Iindlela ezimbini zokubona i-intanethi ye-intanethi yokulahlekelwa kwe-dielectric zinokubonelelwa, ezinokulinganisa ukuhlukana kwe-dielectric loss kunye ne-capacitance ratio yezixhobo ezimbini ze-capacitive kwisigaba esifanayo, kunye ne-PT ye-voltage yesibini ingasetyenziselwa njengesalathisi sokulinganisa i-capacitance kunye ne-dielectric. ilahleko yesixhobo.Ukusebenzisa i-sensor yangoku kunye neteknoloji yokucoca idijithali ephuculweyo, ingxaki yokuchaneka kwelahleko ye-dielectric kunye nokuzinza isonjululwe, idityaniswe nemilinganiselo yokukhusela i-electromagnetic egqibeleleyo kunye neteknoloji yokuqhubela phambili, ukucoca idijithali kunokuqinisekisa iziphumo zovavanyo lwelahleko ye-dielectric azichatshazelwa yimpembelelo yokuphazamiseka kwe-harmonic. kunye nokuphazamiseka kwentliziyo, ngokuchaneka ngokupheleleyo ukuya kuthi ga kwi-±0.05%.
5. Ngokufunyaniswa kokwahlukana kwelahleko ye-dielectric kunye ne-capacitance ratio ye-in-phase capacitive equipment, ayikwazi ukuphepha kuphela ukuphazamiseka kwesiphumo sovavanyo lokulahleka kwe-dielectric okubangelwa ukusebenzisa i-PT yombane wesibini njengomqondiso wesalathiso, kodwa inokunceda ukunciphisa impembelelo Ukuphazamiseka kwintsimi yombane yesigaba ukuya kwisigaba.
6. Umtshini uxhotyiswe ngesikrini esikhulu se-LCD sokubonisa i-voltage esweni, i-current, i-dielectric loss, i-resissive current, i-capacitive current kunye nezinye iinkcukacha.
7. Umvavanyi akanalo kuphela umsebenzi wokubona ubomi, kodwa unokubeka iliso kwi-intanethi ixesha elide, kwaye urekhode ngokuzenzekelayo idatha esweni.
8. Inkqubo ithatha i-sensors zangaphandle endaweni ye "traditional sampling unit", enokuthi iphuculwe ngokulula ukusuka "kubonwa okuphilayo" ukuya "kukubeka iliso kwi-intanethi" phantsi kokusebenza ngokuqhelekileyo kwesixhobo.Akukho mfuneko yokususa izinzwa ezifakiweyo, akukho mfuneko yokukhubaza isixhobo, yongeza nje iyunithi yokubeka iliso (IED).
9. I-detector ithatha idizayini ephathekayo, ilula ukuyisebenzisa, ibhetri ye-lithium kumatshini inokugcina iiyure ze-8 zexesha eliqhubekayo lokusebenza, ukuhlangabezana ngokupheleleyo neemfuno zokusetyenziswa kwentsimi.
