GDF-3000A DC System Earth Fault Detector
Zolakwika zamtundu wa DC, zolakwika zapakati pa DC ndi kulephera kwa magetsi a AC ndizolakwika zomwe zimakhala zowopsa komanso zovulaza mphamvu zamagetsi, ndikuyika pachiwopsezo magwiridwe antchito amagetsi.
Pofuna kuthandiza bwino ogwira ntchito yosamalira minda kuti apeze zolakwika za DC mwachangu komanso molondola, kampani yathu yapanga chowunikira cha DC pazaka zoyeserera ndikuphatikiza zokumana nazo zambiri zakumunda.
Chowunikira cha DC chimagwiritsa ntchito makina owongolera olondola kwambiri kuti azindikire ndikupeza zolakwika pogwiritsa ntchito kusiyana kwaposachedwa kwa DC panjira yolakwika.Ukadaulo wosintha mwachangu wa FFT umalowetsedwa mu chipangizo chofufuza zolakwika za DC, kuti muwone zolakwika zamitundu yosiyanasiyana, zolakwika za DC, komanso kulephera kwamagetsi a AC mumagetsi a DC okhala ndi ma voltage osiyanasiyana (24V (posankha), 48V, 110V, 220V).
Pakuchulukirachulukira kofunikira pakugwiritsa ntchito moyenera machitidwe amagetsi, zofunika pamitundu yosiyanasiyana ya DC yopeza zolakwika m'makina amagetsi zidzakweranso.Chifukwa chake, kulondola kwambiri, kusanthula kwamachitidwe kudzakhala zofunika kwambiri pa chipangizo chamagetsi cham'badwo watsopano wa DC.
(1) System-to-ground voltage muyeso ntchito, chida akhoza kuyeza dongosolo-to-pansi voteji, negative-to-pansi voteji, dongosolo voteji, ndipo akhoza kuzindikira voteji polojekiti osiyanasiyana 0-300V;
+
(3) AC mphamvu kuzindikira ntchito, chida akhoza kuweruza AC mphamvu kulephera mu dongosolo DC, ndipo akhoza kuyeza AC voteji mtengo mu dongosolo DC, ndi AC voteji kuyeza osiyanasiyana 0-280V;
(4) dongosolo anagawira capacitance kuyeza ntchito, chida akhoza kuyeza capacitance anagawira dongosolo ndi kusonyeza mu nthawi yeniyeni;
(5) Kuzindikira kwa ma netiweki a mphete ndi kuyika ntchito, chidachi chimatha kuzindikira zolakwika zosiyanasiyana zamaukonde mumipiringidzo iwiri yamabasi, kuphatikiza mphete zabwino, mphete zoipa, mphete ya bipolar ndi mphete ya bipolar, etc., kupeza malo olakwika a netiweki ya mphete;
(6) Chipangizocho chili ndi kusinthasintha kwa matalikidwe, kukonzanso, kusankhidwa kwa mawonekedwe amakono ndi ntchito yosankha njira yogwirira ntchito, yomwe imatha kuzindikira kusaka ndi malo a zolakwika zapaintaneti zotsutsana ndi mphete.
(7) Nthambi kutchinjiriza kukana muyeso ndi kutchinjiriza kulakwitsa malo ntchito, chida kuyeza kukana kutchinjiriza wa nthambi iliyonse pansi, ndipo akhoza kuzindikira malo kutchinjiriza mfundo zolakwa kudzera waveform anasonyeza ndi kusonyeza malangizo;
(8) Kulakwitsa kwaposachedwa kusanthula ntchito, chipangizocho chimatulutsa bwino matalikidwe a chizindikiro cha malo omwe amayezedwa pafupipafupi, ndikuwongolera kuzindikira kolondola ndi ntchito yowunikira ma sipekitiramu akusintha kwakanthawi ndikusintha mwachangu kwa FFT;
(9) Ammeter ntchito, chipangizochi chingagwiritsidwe ntchito ngati ammeter yolondola kwambiri, ndipo kusamvana kwamakono kungafikire 0.01mA;
(10) Mawonekedwe a Waveform curve ndi ntchito yowonetsera mayendedwe.Mukamagwiritsa ntchito chowunikira kuti muzindikire nthambi yoyezedwa, iwonetsa kusintha kwaposachedwa kwa nthambi yoyezera ngati mawonekedwe a curve yowonekera pazenera, zomwe zimakhala zosavuta kuti wogwiritsa ntchito azindikire cholakwikacho mwachangu komanso molondola.Pezani mayendedwe olakwika pomwe pali cholakwika cha mphete ndi cholakwika chapansi.
●High kudalirika mapangidwe
Chipangizocho chimatenga 32-bit microcontroller yotumizidwa kunja monga dongosolo lalikulu, ndipo mapangidwe a hardware amatsatizana ndi mphamvu ndi mphamvu zamagetsi.Njira yamkati ya redundancy imatengedwa kuti iwonetsetse kudalirika kwa chipangizocho ndi chipangizo chomwe chikuyesedwa.
●Kusankhidwa kwazinthu zolondola
Chipangizocho chimatenga chojambulira cholondola kwambiri ngati gawo lotengera ma siginecha, ndipo sampuli yamagetsi imatenga chip chosinthira cha analogi-digito cholondola kwambiri, voteji ndi impedance zimayesedwa molondola;
●Kulumikizana kwamunthu ndi makompyuta
Onse osanthula ndi chowunikira amagwiritsa ntchito mawonekedwe a kristalo amadzi a TFT kuti ogwiritsa ntchito awone zambiri;
Opaleshoniyo ndi yophweka komanso yofulumira, ndipo pamene kudziwika kwa nthambi zosiyanasiyana kukuchitika, batani loyambira limodzi lokha likhoza kumalizidwa;
Zotsatira za mayeso ndizolunjika ndipo zotsatira zoyesa zimatha kuperekedwa kwa wogwiritsa ntchito m'mawonekedwe osiyanasiyana, kuphatikiza mawonekedwe oyambira kapena osasunthika, milingo ya insulation, kukana kutsekereza, kutayikira kwapano, komanso chidziwitso chamayendedwe.
●Dongosolo lozindikira komanso kuzindikira mwanzeru
The analyzer amazindikira dongosolo voteji mlingo;
The analyzer akhoza kudziwa mphete yolakwa gulu;
Chidziwitso cha detector ndi analyzer chikalumikizidwa kamodzi, sichingakhudzidwe ndi mtunda wodziwika;
Chojambulira chikayang'ana, wokhometsa amatha kumangitsa chingwe chimodzi chamagetsi kapena kumangitsa zingwe zamagetsi zingapo kuti azitha kuzindikira bwino;
Pambuyo poyeserera kwa detector, ngati nthambi yoyesedwa ili ndi netiweki ya mphete kapena cholakwika cha kutchinjiriza, chidziwitso chowongolera chokhudzana ndi malo oyeserera chimatsimikiziridwa.
●Kumaliza kuyesa ntchito ndikutha kuthana ndi zolakwika
Module yotumizira ma data opanda zingwe imamangidwa pakati pa analyzer ndi chowunikira cholumikizirana.Ntchito yoyesera ndi zidziwitso zowonetsera zatha, ndipo zimatha kuthana ndi ma netiweki a mphete osiyanasiyana ndi zolakwika zamtundu wa DC.
Analyzer ali ndi njira zosiyanasiyana zogwirira ntchito posankha ntchito za "Amplitude Modulation", "Waveform" ndi "Mode", zomwe zingagwirizane ndi zochitika zosiyanasiyana zovuta.
●Chitetezo chapamwamba
Chipangizocho chimatenga chizindikiro chodziwikiratu cha micro-amplitude ndi chowunikira chapamwamba kwambiri cha DC kuti chizindikire zolakwika ndikuyika, ndipo sichikhudza dongosolo la DC.
